TD-36 485
Telephone modem, RS-232/422/485
The TD-36 485 is designed to function reliably within industrial environments and in
areas of high level interference. The modem has an RS-232 and RS-422/485 interface
supporting terminal data rates up to 115 kbit/s. 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
software but also has DIP switches to assist configuration. Drivers for Windows setup
are also supplied.
