No arguments.
Return
The number of the fi rst RGB PIP card. There are two valid values that this command can return “0” or “1”. If there is an RGB PIP provided with the display this command is issued to then “1” will be returned otherwise “0” is returned indicating that there is not an RGB PIP present. The syntax for the returned value is the following:
=<value>~~~~
where “value” = the number of the fi rst RGB PIP.
LAST NTSCDescription
LAST NTSC is used to query the controller for the number of the last NTSC PIP card in the display’s confi guration. If the FRST NTSC command returned “0”, indicating that no NTSC PIPs are present, then this command will return “0”.
Argument
No arguments.
Return
The number of the last NTSC PIP card. Valid return values for this command are 0 to the maximum number of PIPs the display’s confi guration can accept. The syntax for the returned value is the following:
=<value>~~~~
where “value” = the number of the last NTSC PIP.
LAST RGBDescription
LAST RGB is used to query the controller for the number of the last RGB PIP card in the display’s confi guration. If there is not an RGB PIP present in the confi guration (the FRST RGB command returned “0”) then “0” is returned.
Argument
No arguments.
Return
The number of the last RGB PIP card. Valid return values for this command are “0” to the maximum number of PIPs the display’s confi guration can accept. The syntax for the returned value is the following:
=<value>~~~~
where “value” = the number of the last RGB PIP.
The range of values returned by the FRST, LAST commands represent the values that are to be used to indicate the PIP number in the command structure. If for example the FRST RGB command returns a “1” and the LAST RGB command returns a “3” then there are 3 RGB PIPs on which commands can act. Therefore there are four valid values that can be
