The Westermo 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 “watchdog” 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 answering 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.
