User manual GRASS VALLEY 8937D DATASHEET

[. . . ] [. . . ] Both channels are fully DVB ASI compatible and can be used in any application where standard SDI video or ASI signals are to be copied and distributed. The standard reclocker circuits greatly reduces jitter-induced over cable runs adjacent to high power lines or from unstable sources of standard data rate signals. The reclocker can easily be disabled to pass SMPTE 310M and other nonstandard data rate signals. A user-enabled video presence detection feature generates individual SNMP traps for each channel that can be sent to our NetCentral SNMP manager or other SNMP systems.
