XML Identification Document URL
As required by the LXI standard, the instrument provides an XML identification document that can
be queried via a GET at "http://<hostname>:80/lxi/identification" that conforms to the LXI XSD
Schema (available at http://www.lxistandard.org/InstrumentIdentification/1.0) and the W3C XML
Schema Standards ( http://www.w3.org/XML/Schema ). This document describes the instrument.
TCP Sockets
The instrument uses 2 sockets on TCP port 9221 for instrument control and monitoring. Text
commands are sent to this port as defined in 'Remote Commands' and any replies are returned
via the same port. Any string must be one or more complete commands. Commands may be
separated with either semicolons ";" or line feeds. No terminator is required since the TCP frame
contains complete commands though commands may be sent with a terminator if desired (it will
be ignored). Each command over TCP behaves as if it is terminated with a command terminator
(ASCII character 0AH, line feed).
GPIB Interface
The GPIB interface 24-way connector is located on the instrument rear panel. The pin
connections are as specified in IEEE Std. 488.1-1987 and the instrument complies with IEEE Std.
488.1-1987 and IEEE Std. 488.2-1987.
