Kramer VP-23 Switcher

Frankie

Has any one controlled this switcher? I can switch the video/rgb but i cant get the audio to switch out the "Master Output".

Thanks

Hi Frankie,

At first the commands:
(*commands for cvs inputs ****KR_VP23_DATA1*****)
KR_VP23_CVS1 ="$01,$81,$81,$81"
KR_VP23_CVS2 ="$01,$82,$81,$81"
KR_VP23_CVS3 ="$01,$83,$81,$81"
KR_VP23_CVS4 ="$01,$84,$81,$81"

(* the audio master commands *****KR_VP23_DATA2 *****)
KR_VP23_MSTR_CVS="$02,$81,$81,$81" (* AUDIO from CVS INPUTS *)
KR_VP23_MSTR_YC ="$02,$82,$81,$81" (* AUDIO from YC INPUTS *)
KR_VP23_MSTR_VGA="$02,$83,$81,$81" (* AUDIO from VGA INPUTS *)

You need to send the two commands see code below:

DEFINE_CALL 'KR_VP23_CTRL' (KR_VP23_DATA1[4],KR_VP23_DATA2[4])
{
SEND_STRING KR_VP23,KR_VP23_DATA1 (* switch inputs in a group*)
WAIT 1 'KR_VP23_TIMER'
{
SEND_STRING KR_VP23,KR_VP23_DATA2 (* switch audio to master*)
}
}

Good luck

Thanks Leo. Thats what I was doing but the audio would not switch... Maybe its a bad switcher?

Hi there Frankie,

However did you try to switch manually and does that works? If not
there a few other possibility's:

1. How is the audio Breakaway setting (Position 8 in the rs232 manual)?
2. Is the audio level knob on the zero position (no audio to master out)?
3. Is the talkover button stuckt (is it pushed and by a mechanical problem never released)?

That's all i can think about at this moment. If all this makes no sence that maybe you should send the switcher to repair.
Good Luck
