4 Remote Interface Reference
The Model 187 provides the capability of supporting RS-232 and IEEE
488.2 compliant interfaces simultaneously. Upon request, the RS-232 port
can be reconfigured for RS-422 operation. Separate output buffers are
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:
W Braces { } enclose valid parameter choices.
W A vertical bar | separates multiple choices for each parameter.
W Triangle brackets < > indicate that you must supply a value.
For example, the command UNITs {0|1|2} indicates that the command
UNITs has three parameter options: 0 , 1 , or 2 . 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.
