1. INTRODUCTION
In the modern automatic measurement system, communication between
equipments and computers is essential. The measuring procedures can be
varied with users’ testing programs, therefore, the programmable power
supply can be operated remotely from an instrument controller or computer
through
the RS232 interface (optional) or GPIB (optional).
Interface selection and setup
The GPIB address can be changed in normal operation condition. Press
[SHIFT] key and [LOCAL] key on the front panel, in which the last
transmitting interface settings will be displayed. Select interface and press
[ENTER], then select the baud rate (or GPIB address) and press [ENTER]
to confirm the setting by using the knobs.

2. CONNECTING THE PROGRAMMABLE POWER
SUPPLY VIA GPIB INTERFACE
The GPIB interface capabilities:
The GPIB interface of the programmable power supply corresponds to the
standard of IEEE488.1-1987, IEEE488.2-1992 and SCPI-1994. The GPIB
interface functions are listed as follows:
SH1(Source Handshake) : The power supply can transmit multilane
messages through the GPIB.
AH1(Acceptor Handshake) : The power supply can receive multilane
messages across the GPIB.
T6(Talker) : Talker interface function includes basic
talker, serial poll, and unaddress if MLA
capabilities, without talk only mode
function.
L4 (Listener) : The power supply becomes a listener when
the controller sends its listen address with
the ATN (attention) line asserted. The
power supply does not have listen only
capability.
SR1 (Service Request) : The power supply asserts the SRQ (Service
request) line to notify the controller when
it requires service.
RL1 (Remote/Local) : The power supply responds to both the
GTL(Go to Local) and LLO(Local Lock
Out) interface messages.
PP0 (Parallel Poll) : The power supply has no Parallel Poll
interface function.
