About This Manual
This technical manual is for the RS-232 Interface; a microprocessor-controlled
option card for all models of XFR Series and XHR Series DC output power supplies.
This manual provides you with specifications, user options, and configuration
instructions for the interface, along with a command set which allows you to control
your power supply from a computer console. Error messages and calibration
procedures are also included.
This manual is designed for the user who is familiar with basic electrical theory
especially as it applies to the operation of power supplies. This implies a recognition
of Constant Voltage and Constant Current operation modes and the control of input
and output power, as well as the observance of safe techniques while effecting
supply or pin connections and any changes in switch settings. The user should also
have experience with a computer-based communications software package.
Refer to your power supply manual for installation, configuration, and operating
procedures for your power supply.
