1.1 Interface Connection
RS-232
For RS-232 connectivity, refer to the diagram below for pin out information. The RS-232 is
labeled in the rear panel and it is a female DB-9 interface.
A straight pin-to-pin DB9 female to DB9 male serial cable is required for using the RS-232
interface. Do not use a null modem or crossover DB9 serial cable.
Refer to the user manual for details on configuring all serial settings as required for RS-232
communication.
USBTMC
The standard USB port is a USBTMC-compliant port that can be used for remote communication.
There are no settings in the menu system for USB configuration. The only requirement is that
NI-VISA is installed on the computer, which can be downl oaded at http://www.ni.com/visa/.

2 Remote Commands
2.1 Parameter Definitions
The 9800 Series po wer supplies support c ommunication proto cols, which include standard SCPI
commands and a few proprietary command s that follow the SCPI convention. The SCPI i nt erface
enables users to operate the power suppl y t hrough a computer or a terminal equipped wi t h RS-232,
or USB interface. SCPI IEEE-488.2 also sup ports multi-unit control allowing a user to control up to 32
power supplies.
The following table lists all of the numerical parameters.
All commands sho uld be ended with the <Rtn> a nd <NL> and there should be a space between
command and numerical parameter.
2.2 IEEE488.2 Common Commands

2.3 STATUS Subsystem
You can get the current status of the power supply by reading the operation status registers. The
power supply records the different status of the instrument through the four status register
group. The four status registe r groups are: status byte register, standard event regist er, query
status register and operation status register. Status byte register records the informa ti on of the
other status registers.
