    8.8. Global Output Commands 8.8.1. Description Global commands are a way to quickly set all power supplies on the RS-232/RS-485 Digital communication bus to the same setting. For example, sending “GOUT OFF” is one way to turn a whole group of supplies OFF at nearly the same time. CAUTION After sending a global command, it is important that the controller wait 200 mSec before sending any more RS-232/RS-485 messages.

  • Page 92: Fast Queries

    8.9. Fast Queries These are commands that read a response very quickly from the Power Supply. They use unprintable character codes. They allow the Power Supply to avoid the normal command processing delays. The processing time for these queries is typically 2ms, so total query speed is 2ms plus the RS-232/RS-485 transmission time.
