SECTION 5
REMOTE PROGRAMMING
The rear panel of the SLM mainframe is designed to connect with a PC (Personal Computer) or
Notebook PC through GPIB or RS-232 interfaces.
5.1 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
mainframe to be active simultaneously. This feature can greatly reduce the testing time and increase
efficiency.
5.2 RS-232 Interface and Commands
The following RS-232 commands are the same as GPIB commands. The RS-232 protocol in SLM
mainframe is listed as follows:
B AUD - RATE 9600
Parity none
Data bit
8 bits
Stop bit 1 bit
Command delay time 20 msec.
