VISA Resource Name
Because of the limited support for VXI-11(Discovery Protocol only), the instrument must be referred
to by its raw socket information when used in software packages which communicate via a VISA
resource name. For example, an instrument at IP address 192.168.1.100 would normally have a
VISA resource name of "TCPIP0::192.168.1.100::inst0::INSTR" but for this instrument the name
must be modified to read "TCPIP0::192.168.1.100::9221::SOCKET" where 9221 is the TCP port
used by this instrument for control and monitoring, see below.
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).
LAN Error
If a LAN connection is made but an error is detected (e.g. the IP address is the same as another
device on the network) then the instrument's display will flash alternately between the normal
voltage and current values and LAn Err, until the error is corrected. If a LAN error occurs;
check and correct the configuration of the instrument; a LAN Configuration Initialize (LCI)
mechanism is provided via a recessed switch on the rear panel ( marked LAN RESET) to reset the
unit to the factory default. The default setting is for the instrument to attempt to obtain settings via
DHCP if available or, if DHCP times out (30 seconds), via Auto-IP. In the very unlikely event that an
Auto-IP address cannot be found a static IP address of 192.168.0.100 is assigned.
The display will also flash alternately between the normal values and
connection is found at power on, but will stop flashing after 10 seconds. To disable this message at
every power on send the command 'NOLANOK 1' over any interface. To re-enable the message at
power on send the command 'NOLANOK 0 ' or use the recessed rear panel LAN RESET switch to
reset all LAN parameters to their factory default settings, see the introduction to the LAN section.
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.
