Description TR-36 is designed to satisfy industry’s demands on reliability and functionality in environments with high levels of interference. The modem has an RS-232 interface and works both as calling/answering and on 2- or 4-wire leased line. TR-36 can handle rates up to 115.2 kbit/s on the terminal side and up to 33.6 kbit/s on the line side. Specific parameters can also be set in hardware using DIP-switches.

In the TR-36, the termination is combined with fail-safe functionality. The termination is used to prevent undefined states when the bus is in tri-state condition.
Mounting /Removal Before mounting or removing the unit: This unit has one separate protective earthing terminal (marked with “symbol” ), while the unit is provided with two mains supply connectors. The grounding terminal of these mains supply connectors is a functional earthing point only. Prevent access to hazardous voltages by disconnecting the unit from AC/DC mains supplies and all other electrical connections.

Please refer to TD-Tool for a complete description of the functionality of the Windows program.
Application example … TR-36 connected to TR-36 with DTR signal call PSTN Network Configure the units AT&F Set the unit to factory default. AT&W Store default settings. Set up the connection – The dialling modem AT&Z0=”nnn” Store the number of the remote modem in the dialling TR-36. AT&S0 Set DSR signal always high (if this signal is used to trig the DTR). AT&B1 Activates automatic DTR dialling if DTR switches from low (OFF) to high (ON). AT&W Save settings.
… TR-36 – Secure Call-back The TR-36 is connected to a PLC which one want to restrict access to. The TR-36 can support access control through the Secure Callback function. In this example password and callback to a predefined number is chosen. The modem in the calling end is here chosen to be a PSTN modem, but can be any of the PSTN, ISDN or GSM modem from Westermo product range.
PSTN Network Set up the connection The dialling modem TDW-33 ATD0705123456 CONNECT 9600 Password: n3Y9kA6otYZu8 NO CARRIER The answering modem TR-36 TR-36 answers the call and requests to TDW-33 TR-36 verifies the password to the passwords stored and if true compare dissconnects.
… Silent answering on predefined numbers TR-36 PSTN Network The TR-36 is connected to Power meter which is remotely monitored and the TR-36 shares the PSTN line with normal telephones which is preferred not to give a Ring signal when the meter is read. The TR-36 is setup to answer calls on the Caller ID received, the valid numbers to answer is programmed into the TR-36.
… Frequently used settings for PLC-systems PSTN Network Most PLC-systems and other industrial applications where modems are used require the same changes to the standard settings. The most commonly encountered problems concern speed, parity and control signals from the connected equipment. Speed and parity are changed with the switches under the cover in block S1. If this action does not solve the problem the modem’s answering codes and possible echoing of commands might be the source of the difficulty.
… Leased line connection using 2- or 4-wire Leased Line Leased line connections can be set up using either 2- or 4-wire.When renting a 4-wire line from a telephone company one pair of cables for transmission and one pair for reception are usually provided. The maximum transmission distance depends on the attenuation of the line. The maximum value is theoretically 30 dBm. To have a good error rate it is recommended to keep the attenuation under 25 dB.
… TR-36 485 – two wire half duplex TR-36 485 PSTN Network 1 Termination 2 3 4 In this application the TR-36 is set to communicate with a number of units with RS-485 interface. The communication is 2 wire half duplex at 38.4 kbit/s, 8 data, parity even and 1 stop bit. Configure the TR-36 485 AT&F Set the unit to factory default AT&W Store default settings S2:3 ON RS-422/485 enable RS-232 disable S2:4 OFF Select 2-wire RS-485 S1:4 ON 38.
