… Remote output and transparent mode
In this application the TD-36 485 I/O is used to send a SMS and then make an transpar-
ent I/O connection. The transparent I/O is in this example set up to an IDW-90 ISDN
modem, but can be any of the Westermo remote product supporting Generic I/O
(IDW-90, TD-36 485 and GDW-12).
The TD-36 485 has a alarm signal connected to it’s I/O input, when this input is activated
by the external alarm contact an SMS defined by Entry 1 in the entry list is sent. When
the SMS is transferred Entry 2 is programmed to be trigged. Entry 2 is programmed to
set up an Transparent I/O connection to an ISDN-modem IDW-90. The status of the
alarm signal will be transferred to the remote IDW-90 and activate an Alarm bell.
At this time the SMS should be available on the operators mobile showing the reason
for the alarm. The operator can acknowledge the alarm, the acknowledge signal will
now be transferred back to the originating TD-36 485 and alarm system. The alarm
system will deactivate the alarm output causing the remote alarm bell to stop sounding.
The Transparent I/O connection will be terminated by a programmed timeout.
