VERY IMPORTANT!!! Determine what type of TX102, TX104, or TX108 you have purchased. There are two different types of Telplex: multi-drop (Rev. 3.03) and standard (Rev. 1.04). Multi-drop units are identified by a TYPE A sticker on the rear panel. Standard units do not have a TYPE A sticker. Certain parts of this manual will pertain only to a multi-drop unit and not the standard unit or vice versa.
A Telplex pair may be used in a "point-to-point" application where up to two, four, or eight separate lines of data may be multiplexed and demultiplexed simultaneously between two sites as shown in Figure 1. The Telplex TX104 and TX108 multiplex four or eight individual communications lines into a single composite channel.
Figure 2 Individual Telplex models are self-contained devices which can be desk-top or rack mounted. The baud rate, word size, stop bits, parity, XON/XOFF handshaking and RTS/DSR pass through for all terminal ports are programmable. Other programmable features for the terminal ports include Block Size, Local Access, and Status Messages. Serial Port Destination and Unit Number are programmable for multi-drop units.
System mode (multi-drop units) and Local mode (standard units) allow a local terminal to instruct the Telplex to enter into any of the other modes of operation. Either type of unit communicates in MUX mode when a successful connection has been made with a remote Telplex. While in MUX mode, terminal ports on the local Telplex communicate with designated terminal ports on a remote Telplex. Local Unit Configuration mode allows a local terminal to program the various features on the local Telplex.

This section discusses basic installation instructions pertaining to unpacking your Telplex, obtaining the software from the supplied diskette, power considerations, factory default parameters and composite/terminal port cabling. Operation is described in Section 4, Section 5 discusses configuration and Section 6 provides specific configuration examples. After opening the box, check the packing list that comes with your Telplex to ensure that you have received all components.
Please review the README.RDM file to obtain instructions for TERM.EXE and SMODE.EXE. To view the README.RDM file on your screen, first insert the diskette into your PC's disk drive and then enter the command TYPE README.RDM from your disk drive prompt. To print this file, enter the command COPY README.RDM LPT1: from your disk drive prompt. The TX104 and TX108 require 115 VAC, 50/60 Hz power and come with a three-prong power cord.
From the factory, the Telplex terminal ports come with the following power-up default configuration: Baud rate: 9600, Word size: 8 bits, Stop bits: 1 bit, Parity: None, XON/XOFF TX and RX: Disabled. RTS/DSR pass through: Disabled. Block Size: 32 characters. Local Access: Enabled for Port 1 only. Status Messages: Enabled for Port 1 only.
The composite ports of multiple Telplex units are connected together via external modems (Section 3.5.1) or cable (Section 3.5.2). See Section 3.5.1.1 if connecting a modem to a TX104 or TX108 or Section 3.5.1.2 if connecting a modem to a TX102.
The EIA-232 port of an external modem is DCE (Data Communication Equipment) with a DB-25 female connector. Please see Section 3.6 for a pin definition of a DCE device. Use the pinout shown in Figure 3 to connect an external modem to the TX104 or TX108 COMPOSITE EIA-232 port.
The modem should be connected to the COMPOSITE EIA-232 port on the back panel of the TX102 and the unit programmed to operate with a Line Type of Modem (see Section 5.8). The TX102 composite port has an RJ-45 modular connector. Most modems do not have RJ-45 modular connectors. Therefore, adapters are required to convert the modem's DB-25 connector to a module connector. BayTech has a complete line of RJ-45 adapters that will make your installation quick and trouble free.
See Section 3.5.2.1 if connecting a TX104 or TX108 to a remote Telplex via cable or Section 3.5.2.2 if connecting a TX102. If you wish to connect the composite port of a local TX104 or TX108 to a remote Telplex via cable, use the COMPOSITE EIA-422 port on the back panel of the TX104 or TX108 (see Appendix B). You must program the unit to use a Line Type of direct (see Section 5.8).

WARNING: Do not use a cable longer than 150 feet to connect the TX102 to a remote Telplex. If connecting a terminal device to a TX104 or TX108, refer to Section 3.6.1. Refer to Section 3.6.2 if connecting to a TX102. IMPORTANT: Before you proceed with cabling, you must know whether the terminal devices that you will connect to your Telplex are DTE (Data Terminal Equipment) or DCE (Data Communication Equipment).
If you are interfacing a DCE device to a DTE device, use a one-to-one straight cable as shown in Figure 7. If you are interfacing a DCE device to a DCE device, used a crossed cable as shown in Figure 8.
The terminal ports on the TX102 have RJ-45 module connectors. Most serial computers, terminals, and printers do not have RJ-45 modular connectors. Therefore, adapters are required to convert either DB-25 or DE-9 connectors to modular connectors. BayTech has a complete line of RJ-45 adapters and cables that will make your installation quick and trouble free.
Section 4.1 discusses terminal port operation, Section 4.2 discusses composite port operation, Section 4.3 discusses the different operating modes, Sections 4.4 and 4.5 discusses the LEDs and SELECT switch functions, and Section 4.6 discusses data flow control. The TX102, TX104, and TX108 multiplex two, four, or eight lines of data respectively. Multiplexed data is sent sequentially over a single telephone communication line or cable.
" Multiplexed data from individual terminal ports is sent and received by the composite port in blocks. The Block Size for individual terminal ports may be programmed from 1 to 255 characters. If a terminal port requires a higher priority, the port would have a larger Block Size than the other terminal ports. For example, if a port on a main frame computer system is primarily sending data to a remote terminal, the main frame port could be programmed to have a higher data block size.
A standard unit will send a message similar to the following for a TX104 when the Telplex is powered up and when MUX mode is terminated (see Section 4.3.3): TX104 in Local mode --- Type +++ to Access Local Mode When a standard unit enters into MUX mode, the Telplex will send the following message: TX104 in MUX mode A multi-drop unit will send the following message when the Telplex is powered up and when returning to MUX mode from System mode (see Section 4.3.
NOTE: This section does not apply to standard Telplex units. Serial Port Destination is the remote Telplex terminal port a local terminal port will connect to once a communication link is established. The Serial Port Destination consists of the remote Telplex's Unit Number, Module Number and Port Number. The Unit Number may range from 1 to 32, the Module Number may range from 1 to 16 and the Port Number may range from 1 to 8.
Data transfer between a local and remote Telplex is accomplished via each respective unit's composite port. Each unit generates and traps internal commands used to transmit and receive terminal port data over the composite link. These internal commands are stripped out of the data stream and are not seen by the terminal ports. This makes the data flow between respective terminal ports totally transparent.
If you configure your external modem to use leased lines and are using Hayes compatible modems, the local modem should be programmed to operate using either auto originate (ATO) or auto answer (ATA) and the remote modem should be programmed to operate using either auto answer or auto originate respectively. You can program the Telplex to send out the auto originate or auto answer AT commands to the external modem upon power-up , loss of DCD, or manually using the Programmable Strings (see Section 4.2.2.3).
There are seven operating modes for multi-drop units: System mode, Local Unit Configuration mode, Remote Unit Configuration mode, MUX mode, Local Diagnostics mode, Remote Diagnostics mode, and Access Local Modem mode. There are four operating modes for standard units: Local mode, MUX mode, Local Unit Configuration mode, and Remote Unit Configuration mode. Sections 4.3.1 through 4.3.5 describe each operating mode in detail.
NOTE: Item "6" (Access Local Modem) will appear in the System Menu only when using Modem Line Type. If using Modem Line Type and the Telplex enters System mode, the unit will send +++ to the external modem which will put the modem into command mode. The Telplex will send ATO to the local modem when you type "3" (Mux Mode) from the System Menu. This will instruct the local modem to return to data mode.
If Local mode is currently accessed by another terminal port, the Telplex will send the following message: Local Mode Currently Being Accessed by another Port Local and Remote Unit Configuration mode are used to program the various features of the local Telplex or a remote unit. For multi-drop units, Local Unit Configuration mode is accessed by typing "1" from the System Menu and Remote Unit Configuation mode is accessed by typing "2" from this menu.
In MUX mode, the local Telplex is connected to a remote unit via the composite link and respective terminal devices are able to communicate back and forth. Data received on a local terminal port is transmitted to the designated remote terminal port and vice versa. MUX mode is accessed in a number of ways depending on the Line Type you are using (Modem or Direct).
NOTE: Standard units support Remote Diagnostics mode only. Diagnostics mode allows the active terminal to perform various tests with a remote Telplex unit if a communication link is established. Multi-drop units also allow the same tests to be performed on the local unit. The active terminal may communicate individually with any port on a remote Telplex or the local unit (multi-drop units only) or perform a self test on all ports.
NOTE: The menu for Remote Diagnostics is identical to this menu except the header will read "Remote Diagnostics Menu". When performing remote unit diagnostics, the local Telplex will first prompt you to enter the desired remote Telplex Unit Number followed by the desired remote module number regardless of the diagnostic you select. The remote module number will be "1" for a remote TX102, TX104, TX108, or TX4. The remote module number will be 1 to 8 for a TX28 and 1 to 16 for a TX60.
If you type "2" from the Local Diagnostics Menu (Self Test Diagnostics), the Telplex will perform a self test on all local ports and will respond with the results shown below: Self Test Module on Local Unit Z passed RAM passed EPROM passed UART passed PORT 4 passed PORT 3 passed PORT 2 passed PORT 1 passed Once the self test has been completed, the Telplex will return to System mode and display the System Menu. If you get a "failed" message after any of the tests, call BayTech at 1-800-523-2702.
Diagnostics mode for a standard unit is accessed from the Remote Configuration Mode menu. This menu is accessed from the Local Mode menu (see Section 4.3.1) by tying Control-R from the active terminal. The Telplex will respond with the Remote Configuration Mode menu as follows Communicating to Remote Unit, Enter ^X to Cancel Bay Technical Associates Model TX108 Statistical Multiplexer Copyright 1990-1992 Revision 1.04 Remote Configuration mode Status..............
If the remote unit fails its self-test, the local Telplex will display one of the following messages: Self-test Self-test Self-test Self-test Failed Failed Failed Failed on on on on Processor Memory Register Port X If you get one of these messages, call BayTech at 1-800-523-2702. The local Telplex will return to the "Run Diagnostic" menu shown on the previous page.
NOTE: This section does not apply to standard units. If you type "6" (Access Local Modem) from the Telplex System Menu (see Section 4.3.1), the Telplex will respond with the following: COMMUNICATING WITH MODEM Type Ctrl U to Send String 1 Type Ctrl V to Send String 2 Type Ctrl X to exit to System Menu Here, you will be communicating in full duplex with the composite port.
NOTE: If the Telplex enters the idle state abnormally (e.g., by the Telplex losing power, but not the local modem) and the local modem is still connected to the remote modem, you should enter into Access Local Modem mode (multi-drop units) or Local mode (standard units) and type ATO. This will cause the Telplex to return to MUX mode. When using Direct Line Type and the power switch is turned on, the Telplex will go through the following sequence: 1) Perform a short self test.
If a multi-drop unit is operating in Local Unit Configuration mode, the function of the remaining LEDs is indicated by the blue TERMINAL labels (TX, RX, RTS, CTS, DSR, DCD, and DTR). These LEDs reflect the state of the active terminal port's EIA-232 lines. If one of these LEDs is illuminated, this indicates that positive voltage is detected on the respective signal.
If a standard unit is operating in Local mode or MUX mode, the function of the LEDs is indicated by the white COMPOSITE labels (TX, RX, DSR, CTS, and DCD). The LEDs reflect the state of the EIA-232 line for the composite port. If one of these LEDs is illuminated, this indicates that positive voltage is detected on the respective signal. # The SELECT switch on the front panel is used for multiple purposes depending upon how Local Access and Line Type are configured.
Once the SELECT switch is released, the Telplex will send a powerup status message as discussed in Section 4.1.2.4. Send the Escape Code Sequence to access System/Local mode. If you access Local Unit Configuration mode, the status menus will show the values currently stored in non-volatile memory. The status menus will not show the temporary changes for Port 1. Cycling power on the Telplex will cause Port 1 to revert back to the values stored in non-volatile memory.
# # # When information is received by a Telplex terminal port, the data is stored in a receive buffer and is subsequently transmitted to the remote unit through the composite port. If the receive buffer fills, the local Telplex will make the terminal port's CTS line false (negative voltage), signaling that it cannot receive more data.
# # If RTS/DSR pass through is enabled for a local terminal port on the Telplex, the state of the RTS input line for this port will be reflected on the DSR output line of the designated remote terminal port. As an example, refer to Figure 1 on page 2. Suppose RTS/DSR pass through for terminal Port 1 on both units is enabled. If Port 1 of Unit 1 receives a false condition (negative voltage) on the RTS line, Unit 1 will signal Unit 2 to make the DSR line of Port 1 false.
The Telplex will also send an XOFF character out of a local terminal port if the transmit buffer of the designated remote terminal port fills. % & When the Telplex transmits data to a terminal device and the terminal device cannot receive any more data, the unit will expect to receive an XOFF character. When the terminal device can receive more data, the Telplex will expect to receive an XON character.
To access Local or Remote Unit Configuration mode for either type of Telplex, use the following procedure: 1. Connect a dumb terminal or a computer emulating a dumb terminal to the desired terminal port (factory default is Port 1). Make sure your terminal device is configured to operate at the same serial parameters as the terminal port on the Telplex. Factory default is 9600 baud rate, 8 bit word size, 1 stop bit, no parity, and XON/XOFF handshaking disabled. 2.
NOTE: If you choose Remote Unit Configuration for a multidrop unit, the local Telplex will first prompt you to enter the desired unit number and module number of the remote Telplex. The module number will be "1" for a remote TX102, TX104, TX108, or TX4. The module number will be 1 to 8 for a remote TX28 or 1 to 16 for a remote TX60. Section 5.1.1 shows the main configuration menu for multi-drop units. Section 5.1.2 shows the main configuration menu for standard units.
A standard Telplex will respond to Control-T (Local Unit Configuration) or Control-R (Remote Unit Configuration) while in Local mode with a menu similar to the following: Bay Technical Associates TELPLEX Model TX104 Statistical Multiplexer Copyright 1990-1992 Version 1, Revision 1.04 Status........................................1 Serial Port Configuration.....................2 Block Size, Local Access & Status Messages....3 Composite Port Configuration.............
By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1.1 or Section 5.1.2) for either type of unit with "1" (Status), you may review the current status of the Telplex and make any necessary changes.
Current Unit Number is: 1 +-------+------------------------------------------+----------+ | String| Programmable String | Send On | +-------+------------------------------------------+----------+ | 1 | | Manual | +-------+------------------------------------------+----------+ | 2 | | Manual | +-------+------------------------------------------+----------+ Press any Key to continue NOTE: The "Remote Destination" and "Current Unit Number" menus shown above and on the previous page will not appear for a sta
Type the desired port number followed by . The Telplex will proceed to a status menu for the port you select and a list of options to change.
You may now select other options from the menu to reconfigure Port 3. For example, to set XON/XOFF handshaking in the transmit data direction, send "6" (Set Xon/Xoff Xmit) in response to the prompt. The Telplex will respond with: Output Flow Control (Xmit) - Xon/Xoff is ( OFF ) Stop/Restart Output Upon Receiving of Xoff/Xon ? (Y/N) : You should then type "Y" to enable Xon/Xoff on transmit or "N" to disable XON/XOFF on transmit.
CAUTION: If the configuration of the device you are configuring from is not changed to match the new configuration of the port, you will be locked out of the Telplex and unable to access its functions. If this happens, cycle power on the unit and re-enter Local Unit Configuration mode. If you enter "Y", the new configuration for that port will be stored permanently in non-volatile memory and the Telplex will subsequently power-up at that configuration.
" ' By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1.1) for either type of unit with "3" (Block Size, Port Local Access, and Status Messages), you may review the current status of the Block Size, Local Access, and Status Messages and make any necessary changes.
Enter the desired block length. NOTE: It is recommended that the transmit Block Size for a particular terminal port be no less than 10 characters due to resulting performance degradation. For example, if you enter "255", the Telplex will respond with: +------+------+------+------------+ | Port | Block|Local | Status | | | Size |Access| Messages | +------+------+------+------------+ | 2 | 255 | NO | OFF | +------+------+------+------------+ Set Block Size.......1 Set Local Access.....2 Set Status Messages..
If you wish to enable Local Access for Port 2, type "Y" in response to the prompt. The Telplex will respond with: +------+------+------+------------+ | Port | Block|Local | Status | | | Size |Access| Messages | +------+------+------+------------+ | 2 | 255 | YES | OFF | +------+------+------+------------+ Set Block Size.......1 Set Local Access.....2 Set Status Messages..
If the current values for Block Size, Local Access, and Status Messages are satisfactory, type "X" in response to the prompt. The Telplex will respond with an updated status menu for all terminal ports and a prompt to enter another port number. You can now enter another terminal port number to change or "X" to exit back to the main configuration menu (see Section 5.1). By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1.
Enter the desired string (up to 42 characters). If String 1 must include control characters, use the prefix ^ (5E hex or ASCII 94) to represent the Control key. For example, if you want the string to include Control-T, you would enter ^T in response to the prompt along with the rest of the desired string. The entry must be followed by the key. NOTE: All AT commands require a Carriage Return at the end of the command(s) before the modem will execute the command(s).
Following our example, type "3" (For Power/DCD) to send String 1 out upon power-up or loss of DCD. NOTE: If you select "4" (For Manual), the programmable string will only be sent manually by typing Control-U for String 1 or by typing Control-V for String 2 when the Telplex is in Access Local Modem mode (multi-drop units) or Local mode (standard units).
NOTE: This section does not apply to standard units. By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1.1) with "5" (Set Serial Port Destination), you may review the current remote destination status for all terminal ports and make any necessary changes.
The Telplex will respond with an updated status menu and prompt to enter another port or "X" to exit. Type the number of any additional port you wish to reconfigure or "X" to exit. ( # NOTE: This section does not apply to standard units. By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1) with "6" (Set This Unit Number), you may configure the Unit Number for the local Telplex.
By responding to the Enter Request: message at the end of the main configuration menu (see Section 5.1.1) with "7" for a multi-drop unit or "5" for a standard unit (Composite Port Configuration), you may review the current status of the composite port and make any necessary changes. Programmable features for the composite port include baud rate and Line Type. NOTE: This choice will not appear in the main menu when performing remote unit configuration.
If you wish to change the baud rate for the composite port to 38,400 bps, enter "D" in response to the prompt and the Telplex will respond with the reconfigured status of the port, the option menu, and the prompt as follows: +------+------+------+------+------+--------+ | Port | Baud | Word | Stop |Parity| Line | | | Rate | Size | Bits | | Type | +------+------+------+------+------+--------+ | 5 | 38400| 8 | 1 | None | Direct | +------+------+------+------+------+--------+ Exit/Save......1 Set Baud Rate..
IMPORTANT: When using Direct Line Type and you change the baud rate of the local unit's composite port, the remote unit's composite port baud rate must then be changed in order to reestablish MUX mode with the local unit. The Telplex will now return to the main configuration menu (see Section 5.1). ) By responding to the Enter Request: message at the end of the main configuration menu with "X" (Exit), the Telplex will return to System mode.
In this application, ports on Unit 1 will communicate with respective ports on Unit 2. Use the following guidelines to configure each unit for this application: 1. Connect a terminal to Port 1 of the TX104 that will be located at the site with the terminals (Unit 2). Access System mode by typing +++. Access Local Unit Configuration mode and change the Unit Number from "1" to "2" (see Section 5.7). If using modems to connect to Unit 1, change the Line Type to "Modem" (see Section 5.
* * For the "star" application, we will consider a local TX60 that has four terminal port modules (installed as Module 1 through Module 4) and four composite modules to communicate with four remote TX104s as shown in Figure 10 below. The TX60 Composite modules are labeled as Composite 1 through Composite 4 and will installed as Module 5 through Module 8 respectively.
The Serial Port Destination for the terminal ports on each TX104 should be configured as follows: TX104 SERIAL PORT DESTINATIONS FOR EXAMPLE "STAR" APPLICATION TX104-X Unit X (Ports 1-4) Serial Port Destination Unit Modul e Ports 1 5 1 1-4 2 5 2 1-4 3 5 3 1-4 4 5 4 1-4 The Serial Port Destination for each TX104 may be configured locally from each unit or remotely from the TX60 once the TX60 has been configured and the composite modules have been connected to the respective TX104 composi
5. ( Connect the composite ports of each TX104 to the respective composite port on the TX60 via modem or cable (see Section 3.5). Once the units recognize one another, you may configure the required Serial Port Destinations for each TX104 (as shown in the table on the previous page) remotely from the TX60. Since there are no adjustments and no moving parts in a Telplex, preventative maintenance is unnecessary.

OTHER BAYTECH PRODUCTS Print Master 700 Series printer controllers are made in several different configurations satisfying various interface requirements. Each unit allows computers to share, select and/or contend for printers easily and economically, without switching cables. The internal buffering system allows simultaneous, high-speed input from all connected computers and output to all printers. Models come in six, eight, and ten port sizes.
LaserShare is an intelligent printer controller that allows up to four or eight computers to send data to a single HP LaserJet laser printer. LaserShare MIO installs into the HP LaserJet Series IIISi, Series 4, and Series 4SI and will support serial speeds up to 460K bps. LaserShare connects directly into the optional I/O or MIO slot of the laser printer. Power is taken directly from the laser printer so there is no need for a power cord.
TRAN-X high speed parallel/serial converter products allow you to extend parallel cables to 1000+ feet and allow your network server, graphics workstation, or PC to send/receive data at speeds up to 46,000 characters per second. You can use the Tran-x Series with BayTech Model 24SII, LaserShare, or network print servers for the fastest long distance peripheral sharing solution available anywhere. Modular cabling provides simplicity in connections between remote devices.
Optical Isolated Input, 16 Channel Switched Input, EIA-232/422 4 serial I/O ports, or EIA 485/422 4 serial I/O ports. System configuration and comprehensive data collection functions are provided through module configuration menus. Telplex Models TX102, TX104 and TX108 are asynchronous statistical multiplexers which multiplex and demultiplex two, four, or eight communications channels over a single channel. This single channel is typically a telephone line or cable.
500 SERIES MULTIPORT CONTROLLERS Included in the 500 Series line of multiport controllers are units intended for the following applications: Port Expansion (A-Series): Allows a single serial port on a computer to individually access up to 17 peripheral devices with full duplex communication. Single Port Contention (DQ-Series): Allows up to 17 terminals to contend for a single port on a computer system.
