1. INTRODUCTION
In the modern automatic measurement system, communication
between equipments and computers is essential. The measured
procedures can be varied with users’ testing programs, therefore, the
programmable power supply can be operated remotely from an
instrument controller or computer across the RS232 interface (standard)
or GPIB (optional).
Interface selection and setup
The GPIB address and RS232 baud rate can be changed in normal
operation condition. Press [UTILITY] key and knob switch or arrow keys
on the front panel, in which the last transmitting interface settings will be
displayed. Select interface and press [EDIT/SAVE], then select the baud
rate (or GPIB address) and press [FIELD] to confirm the setting. Finally,
press [EDIT/SAVE] to store the setup.

2. CONNECTING THE PROGRAMMABLE EST VIA
GPIB INTERFACE
The GPIB interface capabilities:
The GPIB interface of the programmable EST 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 EST can transmit multilane messages
across the GPIB.
AH1(Acceptor Handshake) : The EST 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 EST 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 EST asserts the SRQ (Service request)
line to notify the controller when it
requires service.
RL1 (Remote/Local)
: The EST responds to both the GTL(Go to
Local) and LLO(Local Lock Out)
interface messages.
PP0 (Parallel Poll)
: The EST has no Parallel Poll interface
function.
DC1 (Device Clear)
: The EST has Device clear capability to
return the device to power on status.
