Operation
This chapter provides a detailed explanation of operating your DSS-8224 via GPI or remote panel.
Overview
The DSS-8224 can be operated using a remote control module. Each control module provides push buttons inserts
with LED indicators. The following diagram shows a MRP-8120 Rackmount Control Panel with one of each type
of remote control module.

Up to ten cards can be controlled simultaneously by a single RCM-8120 control module (one Master card and nine
Slave cards). Also, up to three control modules may be connected to a control bus. When multiple modules are
connected to a control bus, selecting the active module is accomplished via a GPI connection on the back of each
control module. Only one module can be active at a time, to avoid bus contention. Non-active modules will indicate
the currently selected Output. The control bus is a single coax cable. It originates at the Master card (BNC 7 for
Output 1, BNC 8 for Output 2).

Output 1 (BNC 7) and Output 2 (BNC 8) cannot be connected to the same control bus.
The control bus provides both power and data communications to the remote modules. Female T-connectors may be
used to split the coax at each card or module to loop the control bus to the next module. Remote modules may also
be connected together via audio/control cable such as Belden 1503A audio/control cable (22 AWG shielded pair).
Remote modules may also be GPI controlled with closed contact or logic low (level or pulse). Four GPI terminals
are provided on the back of each control module, one for each input. For more information, refer to the User
Manual for your RCM-8120.
When operating the DSS-8224 with the control module, connecting multiple cards to the same bus allows you to
switch multiple channels of SDI video, Analog video, AES, and Analog audio simultaneously.
