Note: The 9VDC adapter connection cannot be used in Hazardous Locations. 4.4.3 RS-232 Connection The 5901 may be powered from pin 9 of the RS-232 connector, P4. There are a number of restrictions with respect to the 5VDC tolerance and fuse considerations. Contact Control Microsystems Technical Support for further information when using this method of powering the 5901 modem. 4.5 Configuration Jumpers The 5901 modem uses three configuration jumpers for setting modem operation parameters.
4.6 5901 Modem Reset Control A common problem encountered with consumer modems is the tendency to periodically go into an unstable state. The usual solution for this problem is to simply turn the modem off and then turn it on again. The modem then returns to normal operation. When a modem is used in industrial or commercial applications that require it to be installed in very remote locations this solution is not feasible.
LED Color Function DSR Red DTR OH Red Red The DSR LED is on when the modem is ready to start communication. It is always in a MARK state (on). The DTR LED is on when DTR is asserted by the DTE device. The OH LED is on when the modem is off hook.
5 Operation The operation of the 5901 modem is configured and controlled using commands or strings of commands. These commands are sent to the 5901 through the serial communication RS-232 port. Commands sent to the 5901 are referred to as AT commands. See section 10-AT Command Guidelines for information on how the AT commands are structured. The 5901 modem contains a pre-set operating configuration. This configuration is shown as the default settings in sections 10.2AT Command Set to10.10-At@ Command Set.
Select the Dial Up radio button. Enter the dialing information required to make connection with the remote controller. Some sample Dialing Prefix strings are shown below. To connect to a remote controller that is using a 5901 modem use this command string: Dial Prefix &F0 To connect to a remote TeleSAFE controller that is using a 6901 modem use this command string: Dial Prefix 5.1.
The Modem Command entry box in the INIM element configuration is where the configuration commands are entered. When the INIM function is energized during a Ladder Logic program the command string that is in the Modem Command entry box is sent to the 5901 modem. Note: The INIM function automatically inserts the AT command when the command string is sent to the modem. Note: When using SCADAPack com3 or SCADAPack Plus com3 or com4 the 5901 configuration must disable hardware flow control.
5.3 Operation with Non-Programmable Controllers When the 5901 modem is used with non-programmable controllers it operates as an answer only modem. This mode of operation is typically used with a SmartWIRE 5202 Communication Controller. The 5202 controller is not programmable and cannot send configuration commands to the 5901 modem. The 5901 modem must be configured using a communication program. Refer to the section 5.1.
6 Maintenance This module requires no routine maintenance. If the module is not functioning correctly, contact Control Microsystems Technical Support for more information and instructions for returning the module for repair.
7 Troubleshooting To determine the source of a problem when using the 5901 modem always check the status register of the DIAL or INIM function. The value stored in status register will indicate the type of problem. Refer to the help file in the TelePACE program or to the TelePACE Reference and User Manual. To determine the configuration of the 5901 modem use the &V command. The command format is: AT &V The modem will display the contents of all configuration registers. See section 10.

10 AT Command Guidelines Modem operation is controlled by generic AT commands. These AT commands may be basic AT (i.e., commands preceded by AT, AT&, AT%, AT*, AT\, AT), AT-, or AT#) or S-Register (e.g., S6=n) commands. The command syntax and operation guidelines governing each of these command categories are described in subsequent sections. 10.
10.1.2 Escape Code Sequence When the 5901 modem has established a connection and has entered on-line data mode, it is possible to break into the data transmission in order to issue further commands to the modem in an on-line command mode. This is achieved by the DTE sending to the modem a sequence of three ASCII characters specified by register S2. The default character is '+'.
Minimum, maximum, and default values for S-Parameters may be altered with ConfigurACE. 10.2.3 A - Answer The modem will go off-hook and attempt to answer an incoming call if correct conditions are met. Upon successful completion of answer handshake, the modem will go on-line in answer mode. This command may be affected by the state of Line Current Sense, if enabled. (Most countries do not require Line Current Sense.) Operation is also dependent upon +FCLASS command and countryspecific requirements.
If +FCLASS=1, 1.0, or 2 is selected, the modem will behave as a facsimile modem and attempt to connect to a facsimile machine (or modem) by entering the HDLC V.21 channel 2 receive state (as if +FRH=3 had been issued). This command will be aborted upon receipt of any DTE character if the modem has not finished dialing. In this case, the modem will go on-hook and return to command mode after displaying the NO CARRIER message.
; Return to command state. Added to the end of a dial string, this causes the modem to return to the command state after it processes the portion of the dial string preceding the ";". This allows the user to issue additional AT commands while remaining off-hook. The additional AT commands may be placed in the original command line following the ";" and/or may be entered on subsequent command lines.
I1 Reports the least significant byte of the stored checksum in decimal. Reports 255 if the prestored checksum value is FFh. I2 Reports "OK". I3 Reports identification codes in the form VX.X-F_A where: VX.X = F= Firmware version (e.g., V3.00) Firmware model and ROM size: V90 or V34 = V90 or V34 in 1M ROM V90_2M or V34_2M = V90 or V34 in 2M ROM A= Application DLS = Desktop Serial DLP = Desktop Parallel DLL = Low Power PC Card DL3 = Low Power 3V DLG = Low Power World Class Example: V3.

(Default.) Result Codes: OK n = 0 or 1. ERROR Otherwise. 10.2.
selected and dial tone is not detected, NO CARRIER will be reported instead of NO DIAL TONE. The value 000b is written to S22 bits 6, 5, and 4, respectively. X1 Disables reporting of busy tones unless forced otherwise by country requirements; send only OK, CONNECT, RING, NO CARRIER, ERROR, NO ANSWER, and CONNECT XXXX (XXXX = rate). Blind dialing enabled/disabled by country parameters. If busy tone detection is enforced and busy tone is detected, NO CARRIER will be reported instead of BUSY.
Result Codes: OK n = 0 or 1. ERROR Otherwise. 10.3.2 &Dn - DTR Option This command interprets the ON to OFF transition of the DTR signal from the DTE in accordance with the parameter supplied. The parameter value, if valid, is written to S21 bits 3 and 4. Also, see S25. &D0 DTR drop is interpreted according to the current &Qn setting as follows: &D1 &Q0, &Q5, &Q6 DTR is ignored (assumed ON). Allows operation with DTEs which do not provide DTR. &Q1 DTR drop causes the modem to hang up.
OK ERROR If the modem is connected. 10.3.4 &Gn - Select Guard Tone This command causes the modem to generate the guard tone selected by this command (DPSK modulation modes only). The parameter value, if valid, is written to S23 bits 6 and 7. &G0 Disables guard tone. (Default) &G1 Disables guard tone. &G2 Selects 1800 Hz guard tone. This command may not be permitted in some countries. Result Codes: OK n = 0 to 2. ERROR Otherwise. 10.3.
&M0 Selects direct asynchronous operation. The command sequence &M0\N0 selects normal buffered mode, but the command sequence \N0&M0 selects direct mode. This is because the \N0 command is analogous to the &Q6 command. The value 000b is written to S27 bits 3, 1, and 0, respectively. (See &Q). &M1 Selects synchronous connect mode with async off-line command mode. The value 001b is written to S27 bits 3, 1, and 0, respectively. (Serial interface operation only.

11 Modem S-Registers The modem S-Registers are summarized below along with their default values; registers denoted with an '*' may be stored in one of the two user profiles by entering the &Wn command. One of these profiles may be loaded at any time by using the Zn command. Registers or register fields quoted as “reserved” are reserved for current or future use by the firmware, or are permanently overridden by PTT limitations. All bit-mapped registers are read-only.

12 Modem Result Codes The modem responds to commands from the DTE and to activity on the line by signaling to the DTE in the form of result codes. The result codes that the modem can send are described below. Two forms of each result code are available: long-form, an English-like "verbose" response, and shortform, a data-like numeric response (included in parentheses following the long-form). The longform code is preceded and terminated by the sequence < CR> < LF>.
