Some routers include ‘pulse’ boards that can report the sync rate of the sources connected to
them. This command is a query only command to obtain a source sync rate.
<frequency> is the value returned in the response message and gives the sync rate frequency in
hertz. This value has a resolution of 21 bits and thus a maximum value of 2.09Mhz.
For example, to query for the sync rate of source 2 on level 5:
**G SYNC_REPORT,5,2~!!
The returned response could be:
**G SYNC_REPORT,5,2,35535~!! - or -
**G SYNC_REPORT,5,2,0~!! Indicating that no signal is connected to that source on level 5.
H/V Sync Input Termination
Varname: PULSE_INPTERM
Use: Modify input H or V sync termination for SPII type routers.
Syntax: G VAR2,PULSE_INPTERM,input_num, sync channel [1(H) or 2(V)],value [0 (510ohm) or
1 (75ohm)] ~!!
Example:
**G VAR2,PULSE_INPTERM,5,1,0~!! Set sync input 5 H channel to 510ohms.
Details of the “G” command can be found on our website or by contacting the factory.
