Introduction

GPI Interface
Two independent ground-closure sensing GPI inputs (
sharing common ground connection as chassis potential) are available.
Associated with each GPI user control is a selection of one of 32 user-defined
card presets in which GPI activation invokes a card control preset. Because
the GPI closure invokes a user-defined preset, the resulting setup is highly
flexible and totally user-defined. Invoking a user preset to effect a change
involves card setup communication limited only to the items being changed.
GPI triggering can be user selected to consider the activity on discrete GPI
ports, or combinations of logic states considering both GPI inputs, as well as
be set for level or edge triggering. This flexibility allows multistage,
progressive actions to be invoked if desired. Indication is provided showing
whenever a GPI input has been invoked.
GPO Interface
Two independent phototransistor non-referenced (floating) contact pairs
(
and
) are available. A GPO can be invoked by setting a GPO
GPO 1/1
GPO 2/2
to be enabled when a card preset is in turn applied (i.e., when a preset is
invoked (either manually or via event-based loading), the GPO is
correspondingly also activated.
Serial (COMM) Ports
The 9934-AUD-PRO-DSP is equipped with two, 3-wire serial ports (

de-embedding to an output port, and provide RS-485 LTC I/O (when licensed
with option
). Either port can be configured as RS-232 Tx/Rx or RS-422
+LTC
non-duplexed Tx or Rx.
The card can be set to monitor input video/audio for input errors such as input
LOS, frozen or black frame, loss of reference, closed captioning ancillary data
loss, and/or per-channel audio absences. These alarms can be propagated as a
card general error or warning message, and can be downloaded as basic .txt
logs or via a Syslog function.
User setup tables configure the alarm severity escalation as well as trigger
holdoff/release and other thresholds as applicable.
