Alarm Outputs
Associated with each main output are recessed 2-pin connectors marked Alarm. These provide
access to an opto-isolated NPN switching transistor, the function of which can be set from the
keyboard, see the Alarm Output section of this manual.
The maximum operating voltage that can be applied across the terminals is 20VDC and the
maximum sink current for the switch 'closure' is 1mA.
Do not apply external voltages between the terminals exceeding 30VDC.
RS232 (P models only)
9−pin female D−connector with pin connections as shown below. Can be connected to a
standard PC port using a fully wired 1:1 male-female cable without any cross-over connections.
Signal ground is connected to instrument ground.
USB (P models only)
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
recognise 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 (P models only)
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 Initialise (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 refer to www.lxistandard.org/home
GPIB (P 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.
