Disconnect
” refers to the Unison processor’s status (as named in the Unison menus)
and binding refers directly to the station’s status.
You connect/disconnect the AV/Serial Interface station from the Unison processor in the
same manner as any other Unison station. (Arch>Setup>Stations>Connect|Disconnect)
From the AV/Serial Interface station, you type
Escape
. That clears all bindings for the
station.

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.
