TR-36

Rack modem for industrial PSTN-

and 2/4-wire leased line applications

The TR-36 is an analogue V.34 19”-rack PSTN modem as

well as a industrial 2/4-wire leased line modem. V.34 provides

speeds up to 33.6kbit/s on the communication line. Several

features make it ideal for use in industrial applications: Pass-

word protection, dial-back security and caller ID answering

are only some of this features. For redundant use, the PSTN

dial backup function is useful. In case of a leased line failure,

the modem will establish a dial backup link. The modem has

both RS-232 and RS-485/422 interfaces allowing it to be

used in many different applications. All connections are ac-

cessible from the back of the 19”-card. The TR-36 is the ideal choice for industrial dial-up and 2/4 wire leased

line applications where many modems need to be installed in a small amount of space.

Configuration and diagnostics

The TR-36 is congurable via its serial interface in different ways, either via standard terminal emulation

software using AT-Hayes commands or Westermo’s own modem conguration software - TD-Tool. Additio-

nally the TR-36 can be congured via its onboard DIP-switches. TD-Tool is a Windows based conguration

GUI that simplies setting up the modems, connection statistics can be viewed and congurations saved for

further use. To assit in fault nding and reconguration of unmanned stations, the modem can be congured

remotely via a PSTN connection.

Harsh industrial environment

The TR-36 is designed to function reliably within industrial environments and in areas of high level interferen-

ce. The modem is equipped with transient protection on the line side and a “watchdog” that monitors

and automatically resets the modem in the event of a fault.

The TR-36 is designed to be mounted in Westermo’s RV-07 19” rack which can hold up to 17 TR-36

modems.

Approvals

The construction of the units has gone through extensive testing and approvals both by Westermo and

approved test houses. The TR-36 is approved for use in Europe.
