Introduction
9902-2UDX-DI Functional Description
GPO Interface
Two independent phototransistor non-referenced (floating) contact pairs
(
GPO 1/1
and
GPO 2/2
) are available. A GPO can be invoked by setting a GPO
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 9902-2UDX-DI is equipped with two, 3-wire serial ports (
COM 1 - Serial
Port 1
,
COM 2 - Serial Port 2
). The ports provide for SMPTE 2020
de-embedding to an output port, and provide RS-485 LTC I/O (when licensed
with option
+LTC
). Either port can be configured as RS-232 Tx/Rx or RS-422
non-duplexed Tx or Rx.
Alarm Function
The card can be set to monitor input video/audio for input errors such as input
LOS, frozen or black frame, loss of reference, and closed captioning ancillary
data loss. 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.
