Problems and Solutions
Switching Problems
Switching Latency
All crosspoints involved in a Take do not switch in the same vertical
interval. This can be caused by noisy or missing VI Reference signal and/
or incorrect timing on the Input signals. All Input Video signals are
required to be zero timed. Digital Audio signals are automatically phased
to the Reference signal.
If using a remote panel, check that the Time Server Reference setting is
enabled on the Router Reference Configuration web page.
SNMP Monitoring
Acappella supports the Simple Network Management Protocol (SNMP) for
system monitoring. SNMP Agents reside on the monitored equipment, and
SNMP monitoring software residing on a PC communicate to accomplish
the system monitoring.
SNMP messages originating from Thomson Grass Valley equipment
conform to the following standards:
•
1157 - SNMP v1
•
1901-1907 - SNMP v2c
•
3416 - Protocol Operations for SNMPv2
•
MIB-II - (SysGroup and SNMP Group only)
SNMP Managers

tomer Service for instructions on obtaining MIBs.
NetCentral SNMP Manager
