The following RS-232 setting commands are channel-dependent commands except ”CHAN” which is a
channel-specific
command; therefore, for proper program execution ”CHAN” should be sent first, and
then the channel-dependent command.
For example:
Short ON of Channel 1 of SL-series Electronic Load module, the RS-232 programming
command is: CHAN 1;SHOR ON.
As with the GPIB commands, the following RS-232 commands with [GLOB:] option can set all the SL-
series Electronic load modules in the SLM mainframe to be active simultaneously. This feature can
greatly reduce the testing time and increase efficiency.
