AB Soft TDW-33 Description

86619-2202

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 “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 TDW-33 is ideal for industrial applications as it mounts easily on to a 35 mm

DIN-rail, runs from 12–36 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 soft-

ware. Drivers for Windows setup are also supplied.
