4 Remote Interface Reference
The Model 420 provides both RS-232 and IEEE-488 interfaces as standard
features. Upon request, the RS-232 port can be reconfigured for RS-422
operation. The serial and IEEE-488 interfaces may operated
simultaneously. Separate output buffers are also provided for the serial
and IEEE-488 return data. However, for optimal performance and
simplicity of programming, AMI normally recommends limiting operation
to one interface. An exception to this recommendation would be using the
serial port as a debugging aid during programming of the IEEE-488 port
(or vice-versa), which can prove to be a useful resource.
4.1 SCPI Command Summary
The following manual conventions are used for SCPI (Standard
Commands for Programmable Instruments) syntax for the remote
interface commands:
‡
Braces { } enclose valid parameter choices.
‡
A vertical bar | separates multiple choices for each parameter.
‡
Triangle brackets < > indicate that you must supply a value.
‡
Parentheses ( ) within < > indicate alternative units are available.
For example, the command
PSwitch {0|1}
indicates that the command
PSwitch
has two parameter options:
0
or
1
. Refer to the detailed
description of each command for information regarding specific parameter
choices and their meanings. Capitalized portions of the commands indicate
acceptable abbreviations. Default settings are shown in bold.
