Description
The TD-36 (485) is designed to function reliably within industrial environments and in
areas of high level interference.
The TD-36 (485) is a V.34 modem meaning that it can support bidirectional data rates of
up to 33.6 kbit/s on the PSTN or leased line side. Fast connect ensures that leased lines
can re-establish connections in the range of 5 seconds.
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. These func-
tions together with remote configuration make the modem perfect for installation at
unmanned sites and prevent the need of costly service trips.
The modem also has password protection, dial-back security and caller ID answering to
ensure that only authorised users can communicate with the modem and any connected
equipment.
The TD-36 (485) also has a single digital input and output relay. The input and output can
be used to trigger, or be triggered by a number of different user defined events. Both the
digital input and output are galvanically isolated from the rest of the modem.
For ease of setup the modem is supported by the Westermo TD-tool configuration soft-
ware but also has DIP switches to assist configuration. Drivers for Windows setup are
also supplied.
