I'm trying to configure my homebrew pendant to open the jog tab (display) when ever I hit a jog related key on the pendant. I don't have the ability to send a "Tab" key so I need to do this from within a brain. I did find button command 232 described as tab screen on/off, however this does not work, it just seems to blank the entire display until you toggle it again.

Surely there must be a way???

button 50 maybe?

I'm not sure why you want the jog display to show up since OEM command will work even if the screen is not visible but to expand on what ger21 wrote, the "jog tab (display)" is in fact the screen #50.
You can then send an OEM Button 323 to toggle the visibility on the Jog screen

Also, IMHO the easiest way to send a "TAB" keystroke is certainly to use a Pokey...

323 works, thanks for that, I want the jog display up, because depending on my vantage point I might be looking at the control panel or I might be looking at the touchscreen, I want to make this as user friendly as possible.

Thanks again.
