External System Control of Acappella
Serial Control
An Acappella router can be controlled using the 9 pin RS-422 D connector
on the rear of the router. Acappella supports the Terminal/Computer Inter-
face (T/CI) protocol that employs synchronous serial ASCII commands.
Commands may be issued to control the router by either an operator
entering commands manually (using a terminal interface like hyperter-
minal), or by an automation or other external system. This connection is
point-to-point; a cable from the serial connector on the Acappella router to
the command Input device.
Note Refer to the latest version of the Routing Products Protocols Manual for
information about the Terminal/Computer Interface (T/CI) Protocol used to
control Acappella systems. This manual is available for download on the
Grass Valley web site (see
page 4 ).
