Facility Control

I cant seem to get DashBoard to control XPT's I can control CC's and Cut, but can't get a button to switch the XPT's
This is the code I'm using for RossTalk

RossTalk: XPT [Bus]:[source] (Bus MLE 3 PGM, Source IN 0

Vision 17.2a
DashBoard V7.0.0

Many thanks

I believe somewhere along the line, Vision switched from calling it "MLE" to "ME".
The actual command should look something like ME:3:PGM, IN:0 or, if it is a version that *does* support "MLE" it would be MLE:3:PGM, IN:0
#DashBoard

I did get this code to work for some XPT's:
XPT MLE:3:PGM:IN:1

But I can not get it to work for XPT 0 (Black) or for PVW using this code:
XPT MLE:3:PVW:IN:1

Any help?
#DashBoard

For BLACK, use BK
For Preview, use PST

Example commands:
XPT MLE:1:KEY:1:IN:1
XPT MLE:1:PST:GS:1
XPT MLE:4:PGM:BK
#DashBoard
