TDW-33
Telephone modem, RS-232
The TDW-33 is designed to function reliably within industrial environments and in
areas of high level interference. The modem has an RS-232 interface supporting
terminal data rates up to 115-kbit/s. The TDW-33 is a V.90 modem meaning that it
can support data rates of up to 56 kbit/s on the PSTN line side.
The modem is equipped with transient protection on the line side and a “watch-
dog” that monitors and automatically resets the modem in the event of a fault.
These functions 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 answer-
ing to ensure that only authorised users can communicate with the modem and any
connected equipment.
The TDW-33 is ideal for industrial applications as it mounts easily on to a 35 mm
DIN-rail, runs from 12–48-VDC power supplies, has screw terminal connections and
is tri galvanically isolated.
For ease of setup the modem is supported by the Westermo TD-tool configuration
software. Drivers for Windows setup are also supplied.
