Digital Output
The digital output gives the following functionality:
1. Output Contact
The modem has a change over relay output (SPDT-contact). This output can be
controlled by a remote modem through Transparent I/O and Output service in the
Generic I/O function. The output can also be programmed to follow the local DCD
or DTR signals.
2. Remotely controlled
The output can be programmed to follow a remote modem data input. A remote unit
can also set/reset the output as well as transferring a sequence of “set- and resets” of
the output.
3. Follow DCD/Network
The output can be programmable to follow the local DCD or DTR signal.
Digital Input
The digital input gives the following functionality:
1. Static input
A static digital level trigged input high or low triggers the Generic I/O. With a level
trigged input only the first entry in the Generic I/O list can be trigged by the I/O input.
The input is trigged when the selected level has been stable for ta ms. A new trig will not
occur until the input has return to the opposite state an back again.
