1 Rack mounted telephone- and leased line modem for industrial applications TR-6 Rack modem for industrial PSTNand /-wire leased line applications The TR-6 is an analogue V. 9 -rack PSTN modem as well as a industrial /-wire leased line modem. V. provides speeds up to.6kbit/s on the communication line. Several features make it ideal for use in industrial applications: Password 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- and RS-85/ interfaces allowing it to be used in many different applications. All connections are accessible from the back of the 9 -card. The TR-6 is the ideal choice for industrial dial-up and / wire leased line applications where many modems need to be installed in a small amount of space. Configuration and diagnostics The TR-6 is configurable via its serial interface in different ways, either via standard terminal emulation software using AT-Hayes commands or Westermo s own modem configuration software - TD-Tool. Additionally the TR-6 can be configured via its onboard DIP-switches. TD-Tool is a Windows based configuration GUI that simplifies setting up the modems, connection statistics can be viewed and configurations saved for further use. To assit in fault finding and reconfiguration of unmanned stations, the modem can be configured remotely via a PSTN connection. Harsh industrial environment The TR-6 is designed to function reliably within industrial environments and in areas of high level interference. 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-6 is designed to be mounted in Westermo s RV-07 9 rack which can hold up to 7 TR-6 modems. Approvals The construction of the units has gone through extensive testing and approvals both by Westermo and approved test houses. The TR-6 is approved for use in Europe. Industrial PSTN Modems

For a cable located within m and connected to this port, the use of shielded cable is recommended, this is to minimise the risk of interference. The cable shield should be properly connected (60 ) to an earthing point within m of this port. This earthing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or similar, where the unit is builtin. This conductive enclosure should be connected to the earthing system of an installation and may be directly connected to the protective earth.
