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:
B
AUD - RATE 9600
Parity none
Data bit
8 bits
Stop bit 1 bit
Command delay time 20 msec.
