8.2.3 GPIB Address
The GPIB address (also referred to as the unit address) of the Lx / Ls Series power source is the
same for either language mode. The Unit Address can range from 0 through 31. The Unit Address
is set at the factory to 1 but may be changed by selecting the CONFIGURATION screen and setting
a new value. The value set is retained in non-volatile memory.
In APE mode, the GPIB address is returned by the TLK CFGA query command. The CFGA
command will be accepted but changes to the GPIB listen address will not take effect until input
power on the Ls unit is cycled. This is different than the L Series where the new listen address
takes effect immediately.
8.2.4 APE over RS232
Although not available on the L Series power source, the Ls AC power source also has a RS232C
serial interface. It is possible to use the APE mode over RS232C but this mode of operation is not
formally supported by California Instruments. Certain capabilities such as GPIB trigger and SRQ may
not function when using the RS232C interface. In general, it is recommended to use the normal
SCPI mode when programming the Ls Series over the RS232C interface.
