Changing the Station Type
This process, while simple to do, must be done in the following order for consistently
correct results.
Step 1:
If the AV/Serial Interface station is bound to the Unison processor, manually
disconnect
the station at the Unison processor. (Arch>Setup>Stations>Disconnect)
Step 2:
Send the ST command with the station type you want it to become. Sending the ST
command also executes an
Escape
command at the station to unbind the station
and send a service pin message. (See
Step 3:
Connect
the AV/Serial Interface station at the Unison processor.
(Arch>Setup>Stations>Connect) The station may connect automatically if there is
only single station of that type in the Unison configuration.
