Remote On/Off
A switch closure or logic low between connections Rem Off and COMmon will turn off the output.
Warning! COM is referenced to the output control circuit and will be within ~1V of the
positive output potential.
Do not apply external voltages to these terminals.

Signal ground is connected to instrument ground.
USB
The USB port is connected to instrument ground. It conforms with USB 2.0 (Full Speed) and
accepts a standard USB cable. The Windows plug-and-play functions should automatically
recognize that the instrument has been connected. If the correct driver is not found, follow the
Windows on-screen prompts and install the required files from the CD supplied.
LAN
The LAN interface is designed to meet LXI ( Lan eXtensions for Instrumentation) version 1.2; the
instrument is Class C compliant. Remote control using the LAN interface is possible using a TCP/IP
Socket protocol. The instrument also contains a basic Web server which provides information on
the unit and allows it to be configured. Since it is possible to misconfigure the LAN interface,
making it impossible to communicate with the instrument over LAN, 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.
Further details are given in the Remote Operation chapter. For more information on LXI standards

GPIB (factory option on programmable models only)
The GPIB signal grounds are connected to the instrument ground. The implemented subsets are:
The GPIB address is set from the front panel.
