GPIB

Primary goal of this project is to learn how to communicate over GPIB. Some action I do causes it to twitch on my CAMAC bus analyzer but I can't get it to do much else. I got it to return some data when I messed with the DOWNLOAD menu but not when I actually tried to read a device register.

You need to use this to select RS-232 vs GPIB, baud setitngs, etc. I have yet to get any activity over RS-232 so sticking for GPIB for now.


RS-232

Above: configuration screen

Supports:

  • Baud: 75-19200
  • Data bits: at least 7, 8
  • Stop bits: at least 1
  • Parity: odd, even, none
  • Flow control: at least CTS/RTS off

When I got it settings were:

  • 9600 baud
  • 1 stop bit
  • even parity
  • 7 bits
  • CTS/RTS off


Keyboard

The keyboard (where does this attach?) serial port settings are configured separately than the "RS-232C" settings but are on the same screen
