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 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 authorized 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. |
