Introduction INTRODUCTION Zetron Model 640 Paging Terminal MODEL 640 OVERVIEW The Model 640 is a low cost, fully automatic dial-access paging terminal. The Model 640 is specifically designed to provide flexible paging for industrial plants, hospitals, and low RCC applications. The Model 640 supplies the interface between the telephone and radio systems for paging applications. It performs selective signaling activation and message transmission.
Introduction (like a public announcement system). Numeric pages display a set of numbers (usually a phone number) that the caller keys in by way of DTMF telephone. Alphanumeric pages are text messages sent to alphanumeric-compatible display pagers. Alpha messages can be generated through a variety of input devices, including a standard touch-tone telephone. Talkback paging connects the caller directly with a paging customer who has a portable radio for 2-way communications.
Introduction Remote Transmitter Control The Model 640 is equipped with a modem and tone encoder to remotely control transmitters over a radio or wireline link The Model 640 can control any transmitter capable of decoding analog Motorola PURC tones. A Zetron Model 66 Transmitter can be added to control other types of transmitters that do not use the PURC protocol.
Introduction • Repeat paging • Flexible programming of multiple pager groups • Support for alpha modem plus voice and numeric message entry on every telephone interface • Multiple serial interfaces for direct alpha message entry • Canned alphanumeric messages • Modem access for programming through any dial-up line • System alarm output • Autobauding of the maintenance modem at 300 and 1200 baud • Flexible password protection for individual databases, subscriber phone numbers, alphanumeric

Hardware Overview An uninterruptible power supply (UPS) option (Part No. 802-9049) obtains standby power from storage batteries and keeps the system operating through brownouts and blackouts. Zetron’s standard UPS is a 400 VA unit with built-in batteries that provide 30 minutes of emergency power. Higher capacity UPS options may be available as required. Other UPS equipment can provide more capacity and can even power radio equipment.
Hardware Overview DRAM Memory The DRAM memory (item #3, Figure 2) physically resides in one or more single in-line memory module (SIMM) units installed into J9, J10, and J11. The base area of DRAM memory is loaded with the operating software for the Model 640 paging terminal. This plug-in board is also used for non-volatile storage of the subscriber database. The EMS area of the DRAM memory is used as a storage buffer for the ADPCM voice storage and playback functions.

Hardware Overview CAUTION DID, end-to-end, and ground start matrix configurations do NOT function properly for the Dual Trunk 4-Wire Audio Interface Board. Refer to “E&M Trunk Configurations” on page 25 for operational descriptions of this interface. ROM DISK BOARD The ROM (read-only memory) disk (Part No. 702-9389) stores all of the paging software for the peripheral and main processor boards. It plugs directly into an expansion slot on the main processor board.
Hardware Overview RAM DISK BOARD The RAM (random access memory) disk (Part No. 702-9386) stores the voice prompts and database information. It could also contain paging software in some circumstances to avoid updates to the ROM disk board. The RAM disk (item #7, Figure 2) is essentially like a hard drive in a computer. The RAM disk board is very similar to the ROM disk in design. It usually includes four 128KB RAM chips along with the associated battery back-up circuitry.
Hardware Overview PARALLEL PRINTER CARD The parallel printer option (Part No. 950-9758) enables the Model 640 to print the system log data in real-time. When the printer card is installed in either expansion slot (items #9 and #10, Figure 2), a printer can be connected to the DB-25 that is exposed through the rear of the chassis.

Communications Setup COMMUNICATIONS SETUP OVERVIEW OF MODEL 640 COMMUNICATION Communicating with the Model 640 can be achieved several ways. Zetron has designed the paging terminal to allow for programming flexibility and convenience. A communications link with the Model 640 should be established before the system is interfaced to the radio station and telco. This order of installation aids the technician in “seeing” what is going on with the paging terminal.
Communications Setup MCU (Model 640 Communications Utility) MCU is a user-friendly interface to all aspects of the Model 640 programming. It can be accessed only from a personal computer connected to the Model 640 by way of modem or local serial cable. MCU provides easy-to-follow pull-down menus, on-screen help, and a useful tutorial that overviews the hardware and software of the paging terminal. MCU allows the system operator to monitor system traffic (log files) and view statistics and call counts.

Installation INSTALLATION INTRODUCTION This section contains the information necessary to install the paging terminal. This includes making connections to both the telco and radio station equipment. The information is presented in the form of checklists and step-by-step procedures. Where appropriate, procedures in this section refer to detailed information contained elsewhere in the manual. Installation Overview Initial installation of the Model 640 is usually accomplished in six major steps: q 1.
Installation Installation Warning This equipment generates and uses radio frequency energy. If the Model 640 is not installed and used in accordance with this manual, it may cause interference to radio communications. The Model 640 should only be installed by experienced radio and paging systems personnel. Specialized knowledge in telephone systems is also critical for interfacing the Model 640 with the telephone network. CAUTION Always power down the paging terminal before removing or installing cards.
Installation Telco Terminal Block Adapter Model 640 rear panel Radio Station Equipment (Co-located transmitter, Tx link controller, etc.) Figure 17. System Configuration with the Optional Installation Interface Assembly 66-Type Punchdown Block Installation The other method of installation requires a 66-type punchdown block (Part No. 802-0093 or 8020263) and a female 25-pair cable (Part No. 709-0004) to split the radio station and telco wiring out of the Model 640’s RJ21 connector.
Installation 66-type punchdown block Telco Radio Station Equipment (Co-located transmitter, Tx link controller, etc.) Model 640 Figure 18. System Configuration with a 66-Type Punchdown Block TELCO CONNECTIONS The male 50-pin RJ21 connector on the rear of the Model 640 provides both trunk and radio station interfaces for the paging terminal. As a result, even though the telco and transmitter connections are accomplished separately (different installation instructions), they are not totally unrelated.

Installation q 2. Loosely attach two 440 × 5/16-in spacers to the bottom of the terminal block adapter with two 440 ? 1-in screws as shown in Figure 19. Figure 19. Terminal Block Adapter Installation q 3. Loosely attach the 440 × 1/8-in spacer to the top of the terminal block adapter with the 440 × 3/8-in screw. q 4. Secure the board to the RJ21 interface on the rear of the Model 640 chassis. q 5. Tighten the three screws into the standoffs and the paging terminal.
Installation Note: Once the terminal block adapter is installed, the serial ports for trunks C and D (if a second dual trunk card is installed) are partially blocked. This should not create a problem as long as all alphanumeric serial input is directed to trunks A and/or B. Be aware of this minor inconvenience when configuring the trunks in the database to avoid extra work.
Installation To telco connection To Model 640 terminal block adapter Figure 21. Clamp-On Ferrite (Part No. 305-2025) Installation CAUTION Four clamp-on ferrites (Part No. 305-2025) are supplied with the optional terminal block adapter kit. The ferrites must be installed on each phone cord, immediately adjacent to the Model 640 chassis. Failure to properly install the ferrites may result in radio interference! q 4. Plug a cord into each of the telco jacks on the terminal block adapter. q 5.
Installation 66-type punchdown block (Part No. 802-0093 or 802-0263) R J 2 1 25-pair cable (Part No. 709-0004) To RJ21 radio station and telco interface R J 2 1 Figure 22. Punchdown Block Installation Follow the steps below to connect the punchdown block to the paging terminal: q 1. Power-down the paging terminal. q 2. Obtain or make a cable with a female 50-pin connector (to Model 640) on one end and either flying leads or a male 50-pin connector (to punchdown block) on the other end.
Installation Telco Punchdown Block Interface The block typically has telco wiring on one side and open terminals on the other side. To interface the phone company’s punchdown block to the Model 640, a second punchdown block is usually required to split the radio station and trunk wiring out of the RJ21 connector (already installed above). Figure 23 illustrates the hardware connections between a common telco 66-type punchdown block and the Zetron punchdown block.
Installation q 2. Connect the leads for each Model 640 trunk as shown in Figure 23, using standard 26 AWG wire-wrap wire. Wiring configuration varies by telephone line type. The figure above shows the wiring configuration for an E&M 4-wire telco punchdown block. Notes: Many applications do not require all six of the available phone line pins. For example, a typical 2-wire telco interface only requires the TIP and RING leads for each trunk.
Installation 3. The RING/TIP pair provides two-way audio for DID, end-to-end, and E&M 2-wire tie trunks. The pair also provides “to telco” for E&M 4-wire to CO trunks. 4. The RING1/TIP1 pair is not used with DID, end-to-end, and most E&M 2-wire tie trunks. The pair only provides “from telco” for E&M 4-wire to CO trunks. q 3. Use bridging clips or wire to connect the middle terminals of each row. Again, the appropriate connections depend on the telephone line types.

Adjustment Procedures ADJUSTMENT PROCEDURES OVERVIEW The following procedures describe the level adjustments necessary to make the Model 640 operate properly. Each procedure should be performed following the initial installation process and whenever the hardware configuration changes. For example, if the telephone line signaling format changes, or if new options are purchased, the appropriate levels should be readjusted.
Adjustment Procedures Test Equipment The following equipment is required to adjust the trunk card levels: • buttset • digital voltmeter (DVM) • miniature flat head screwdriver • small Phillips head screwdriver • touch-tone phone Notes: The trunk card adjustments are very important. They affect background noise immunity when recording voice prompts, speech silence compression, DTMF key decoding, VOX disconnect features (if used), and modem communications. Follow each procedure carefully.

Trunk Card Level Adjustments q 8. Set the meter range for 3-5 VAC. q 9. Connect a buttset or equivalent high impedance monitor to the appropriate trunk. q 10. Dial into the trunk (using any touch-tone phone) by way of the local telco CO. q 11.
Adjustment Procedures Hybrid (BAL R and BAL C) Adjustment The BAL R and BAL C potentiometers isolate the trunk card audio output (TO TEL) from the telco line input audio (FROM TEL). The two audio paths are separated into transmit and receive. This is accomplished by adjusting the resistive and capacitive impedance of the active hybrid balance circuit. Some adjustment is usually required to compensate for the particular telephone line impedance to the telco central office.
Adjustment Procedures q 12. Repeat steps #8 and #9 until the pot settings make little difference. q 13. Set the AGC KILL switch back to the normal position (toward the front of the chassis). Note: q This adjustment minimizes signal bleeding from the TO TEL back into the FROM TEL. 14. Hang up the telephone and terminate the call. The hybrid adjustment is complete. STATION INTERFACE ALIGNMENT PROCEDURE The following alignment procedures assure correct radio station interface and optimum signal levels.

Troubleshooting and Repair Network Interface Unit (niu) Diagnostics When a down TNPP link is suspected, the niu command provides some useful diagnostics of the network interface unit. The command can be issued from the plus prompt (+) to determine the nature of the trouble. In addition, the -l switch tells the paging terminal to provide information on the status of each link. For a detailed description of the niu command, see the Model 640 Operating and Programming Manual (Part No. 025-9417).
Troubleshooting and Repair ♦ Data block(s) Each data block contains one page. A TNPP packet can contain more than one data block if each page contains the same routing information (same header). This field is limited in size only by the 1024 character maximum per packet. The Model 640 supports both full capcode paging and ID paging for TNPP networking. Each type of data block has a slightly different format. See Table 25 and Figure 67 for details on the data block fields. ♦ End Flag ETX “♥.
Troubleshooting and Repair Example Valid Entries 5C Description 2 hex digits 01 - FF Packet serial number - differentiates between redundant and original packets Data Block Elements The data block is of variable length. Recall that several data blocks can be included in one packet. Each block must end with an ETB (end of text block) character and the last block must end with an ETX (end of text) character. The block format depends on whether the TNPP format is capcode or ID paging.

Troubleshooting and Repair TNPP Response RS Description Resend - the destination node could not accept the page at this time. An response usually indicates one of three conditions: • the link is too busy (too much traffic or too many long messages) • the destination node is too busy • the page is to long for the destination node to handle The page failed. Solution Check the RF link for excessive traffic. Check the destination node for excessive traffic.
Troubleshooting and Repair Traffic Message Description Solution(s) page timed out Indicates that the outbound page did not receive a response within the specified time-out interval. Check the link connection for excessive noise or a weak signal. This may indicate the network packet modem(s) successfully sent the packet, but the round trip time was too long. packet timed out Indicates that the inbound packet was not received successfully. Usually there was too long of a gap between characters.

The standard includes 256 characters, each identified by a three-digit decimal number (000-255). Audio Identifies anything that is “heard,” either by the human ear or by some equipment. In the Model 640, audio can indicate incoming trunk data (voice, DTMF, or serial) or outgoing station data (voice, serial, digital, or analog).
Glossary Term Definition Busy An already-in-use condition in the radio transmission equipment or phone line. BUSY LED A light on the front panel of the paging terminal that indicates when the radio station is currently being used. This LED corresponds to the busy input signal (pin #41) on the trunk and radio station interface connector. Buttset A modified telephone designed for troubleshooting and repair of telecommunications equipment.
Glossar Term Definition Channel An electronics communications path. A narrow band of frequencies (assigned by the FCC) that a radio system must operate within to avoid interference with other adjacent channels. Circuit A pathway for electrical signals. Class of Service (COS) A set of operating parameters that defines certain paging subscribers. The class of service identifies settings like paging coverage zones, voice and display page limits, caller security codes, etc.
Glossary Term Definition Decoder A device that receives input data and translates it into a usable format. Delay The time difference between initiation of an event and the response. Destination The final paging terminal or coverage region (TNPP node address) for which a page is intended. Deviation Level The range of variation of a specific tone level. The tone deviation is usually set between 3.0 and 4.0 kHz for the Model 640 radio station audio.
Glossar Term Definition DVM (Digital Voltmeter) A piece of test and repair equipment used to measure electrical power in volts. E (ear) Lead The receive line of an E&M trunk. E&M A telephone line type that indicates seizure and supervision on two separate wires. E and M refer to the two data wires - Ear (receive) and Mouth (transmit). Empty Message A tone-only alert that is received by a pager.
Glossary Term Definition Ferrite A metal casing designed to block RF noise interference from the radio station equipment. Six ferrites are included in the installation interface assembly option to protect each of the telco trunk and the radio station connectors. Field A parameter in the Model 640 database that requires a formatted entry. Each database record is made up of one or more fields. Field-Upgrade A modification to the paging terminal equipment that is performed by a technician at the site.
Glossar Term Definition Glare A condition caused when opposite ends of a loop start telephone line are seized simultaneously. A glare condition results in misdirected or incomplete calls. Golay Sequential Code (GSC) A high-capacity digital paging format. Golay is registered to Motorola and features advanced error-correction and fade resistance. The GSC format supports tone, voice, numeric, and alphanumeric paging.
Glossary Term Definition Interference Any noise source that impairs the communication link between two pieces of equipment. Interference can affect telephone connections, RF and µwave connections, and paging transmissions. Initialization String See Modem Initialization String. Installation Interface Assembly An optional kit that simplifies the radio station and telco connections to the Model 640.
Glossar Term Definition Maintenance Port An RS-232 data communication interface between the Model 640 and the office PC. It can be either a local serial connection or a remote modem connection. The maintenance port is needed for updating the database and modifying system operating characteristics. Zetron strongly recommends that a modem maintenance port be available at all times for factory support and troubleshooting.
Glossary Term Definition Multitone A digital pager format that supports tone, voice, and numeric pages. Although somewhat obscure, Multitone pagers are popular for health care applications where combined voice and display messages (such as a patient room number) are desired. NAK A TNPP packet response that a page was not properly received by the destination node. A No AcKnowledge response can indicate too much RF link noise or invalid packet data (capcode, pager format, etc.
Glossar Term Definition Packet A page or set of pages sent between TNPP nodes. Each packet can contain several blocks of data, up to 1024 total characters. A block contains one page and identifies parameters such as the page type, the subscriber ID or capcode, the origination and destination nodes, and the message text. Packet Modem A modem designed for sending TNPP page packets. The packet modem is usually dedicated to TNPP paging applications.
Glossary Term Definition Plus (+) Prompt The actual prompt that indicates a ZLINK connection has been established and the terminal is awaiting a command. The plus prompt is similar to a DOS prompt. It allows the user over 60 commands that provide maintenance and diagnostics of the paging terminal. When the system operator is at the plus prompt, the key can be pressed to access the Model 640 databases.
Glossar Term Definition Progress Tones Different tones and beeps the paging terminal plays to callers to indicate what the Model 640 is doing. Progress tones are invaluable when troubleshooting paging malfunctions. Different tone sequences allow the experienced technician to identify when an error occurred and what the source of the error may be. Prompts A tone or voice message that guides a user through the paging process, telling the user when and what type of action is appropriate.
Glossary Term Definition Receiver An RF unit that accepts incoming signals, extracts the audio portion, amplifies it, and converts it back to the original sound waves. Record A unique set of database parameters. Each database contains one or more records that define some portion of the paging terminal operation. For example, in the Subscriber database, individual paging customers have a record that defines their service. Reformat A reset of the original skeleton databases from the ROM disk.
Glossar Term Definition Routing The data path through which calls or information are passed. In a TNPP or TAP system, routing is the sequence in which a page is passed between paging terminals. Satellite An orbiting system in space that receives radio communications from earth transmitters and resends the information to remote locations. Security Code A number required to access some portion of the paging terminal operation.
Glossary Term Definition Static Interfering noise picked up by a receiver. Static is often caused by lightning or conflicting man-made electrical products. Station See Radio Station. Statistics A mathematical analysis of data. The Model 640 offers statistics on many characteristics of the paging system. For example, a statistics file is available that shows the average and maximum number of pages transmitted per minute. Statistics can be viewed using either ZLINK or MCU.
Glossar Term Definition Terminal Block Adapter An optional interface card for simplified connections to the radio station and telco equipment. The terminal block adapter is part of the installation interface assembly option and plugs easily into the rear panel RJ21 connector. It splits the 50 signals into four 8-pin telephone jacks and two 12-pin Wiedmueller connectors for the analog and digital portions of the transmitter interface.
Glossary Term Definition when the transmitter is remotely located, or when the transmitter is part of a simulcast system. Transmitter Link Controller A piece of equipment that governs how the link transmitter sends out data. The transmitter link controller performs the same functions as a transmitter controller, except it is interfaced to a link transmitter rather than the paging transmitter. Transmitter Zone See Zone. Trunk A wireline data path between communications switching equipment.
Glossar Term Definition Voice Prompts A voice message that guides a caller in using the paging system. Voice prompts tell the user when and what type of action is appropriate. The voice prompts are recorded at the Zetron factory, however, they can be field-recorded for custom applications. Voice Storage The amount of memory available in the paging terminal for temporary storage of recorded voice pages and system voice prompts. Note that the Model 640 does not provide permanent storage of voice pages.
