Remote Control Programming

8.1

Overview

If your unit is fitted with a computer interface option then RS232, USB or LAN connector will
be present on the rear panel based on the order configuration. The interface allows the
power source settings to be configured remotely and measurement data to be retrieved for
analysis and test report generation.
The front panel LOCAL key allows the user to restore LOCAL CONTROL unless the Bus
controller has sent a LOCAL LOCKOUT (LLO) message. The Bus Controller may restore LOCAL
CONTROL by sending a GOTO LOCAL (GTL) message.

Programming Conventions and Notations

The following conventions and notations are used in this section of the manual:
1. COMMANDS are shown in the left hand column in BOLD with NO underline.
2. Command DESCRIPTIONS appear in the right hand column.
3. SCPI is "Standard Commands for Programmable Instruments -1992". Refer to the SCPI
1992 standard for more information. The full standard publication is available from the
IVI Foundation at http://www.ivifoundation.org/
4. Some SCPI keywords are optional, and are ignored by the device. Optional keywords
are enclosed in [ ] brackets.
5. Lowercase letters of commands shown are also optional.
6. The SCPI standard requires uppercase text in all SCPI commands (start with : ), however,
the command parser is not case sensitive and will accept commands sent in lower case.
It is recommended that programming formats follow the SCPI standard.
7. Some SCPI commands have query command counterparts as noted. A query command
consists of the command with a question mark ( ? ) appended at the end. Parameters
cannot be sent with a query. IEEE-488.2 commands do not have query counterparts
unless explicitly shown with a question mark appended.
8. IEEE488.2 common commands start with an asterisk ( * ) and are not case sensitive.
9. All required Functional Elements for devices are implemented.
10. All numerical values are ASCII encoded decimal strings consisting of 1 or more ASCII
digits. 8 and 16 bit register values are binary weighted values represented by an ASCII
string of 1 or more decimal digits. One exception, the Serial Poll byte, is an 8 bit
hexadecimal byte.
11. Multiple Commands and Queries may be sent in one Program Message but each must
be separated by a semicolon ( ; ). The term 'Program Message' refers to one or more
