SECTION 4

GPIB/RS-232 PROGRAMMING

OPERATION

4.1 INTRODUCTION

The rear panel of the SLM chassis is designed to connect with a PC (Personal
Computer) or NOTEBOOK PC through GPIB or RS-232 interfaces.

4.2 GPIB

COMMANDS

The following GPIB setting commands are channel-dependent, except the "CHAN"
command, which is channel-specific; therefore, for proper testing program execution,
the channel-specific command "CHAN" should be sent first, followed by the channel-
dependent

command.

Example:

Short ON of channel 1 of SLM-Series Electronic Load module, the GPIB
programming command is: CHAN 1:SHOR ON.

The following GPIB commands with [GLOB:] option can set all the SL-series load
modules in the SLM chassis to be active simultaneously. This feature can greatly
reduce the testing time and increase efficiency.

4.3 RS-232 INTERFACE AND COMMANDS

The following RS-232 commands are the same as GPIB commands. The RS-232
protocol in SLM chassis is listed as follows:
