The GPIB connector pin-out is defined by the IEEE-488 standard and shown for reference
only in Table 5-7 below.

5.10.6 Remote Control Commands
The USB, RS232, LAN and GPIB interfaces use the same command set for setting of test
parameters. However, there are some functions of the GPIB 488.2 interface that are not
available through USB/RS-232/LAN. The IEEE-488 interface option for the CPS series
conforms to the requirements of the IEEE-488.2 standard.
These interfaces provide all of the control commands and parameter setting commands of
the GPIB interface with the exception of the 488.2 Common Command the Status Reporting
commands and SRQ capability.
For information on supported programming commands, refer to section 7, “Remote Control
Programming”. The identification command *IDN is also available through USB, RS-232 and
LAN interfaces.
The RS485 Serial interface uses ModBUS command packets instead of the SPCI message
based control commands. ModBUS programming is register based instead of message based
and requires values to be put in specific register locations to control the output settings or
register read backs for measurement data. This communication protocol is covered in a
separate manual, “APS_CPS100_Series_AC_Source_MODBUS_Protocol_Guide-PN160954-
10_v1.1.pdf” part number 160954-10 available for download at https://adaptivepower.com
