Analog Out (Single Programmable models only)
Connections V and I
OUT OUT
current limit respectively. The scaling is fixed at 0 to 5 Volts for 0 to 100% of maximum output.
V and I are always present on the terminals, whether the instrument is under local or
OUT OUT
remote control. The COMMON return signal is referenced to the positive output of the power
supply.
Do not apply external voltages to these terminals.
Remote On/Off (Single Programmable models only)
A switch closure or logic low between connections Rem Off and COM will turn off the output. The
COM return signal is referenced to the positive output of the power supply.
Do not apply external voltages to these terminals.
RS232 (XEL-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.
Pin Name Description
1 RI Passively asserted (+V through 10kΩ)
2 TXD Transmitted data from instrument
3 RXD Received data to instrument
4 CTS
5 GND Signal ground
6 RTS
Passively asserted (+V through 10kΩ)
7 DSR No internal connection
8 DTR
9 CD No internal connection
Signal ground is connected to instrument ground.
USB (XEL-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
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 (XEL-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 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 refer to www.lxistandard.org/home
GPIB (factory option on XEL-P models only)
The GPIB signal grounds are connected to the instrument ground. The implemented subsets are:
SH1 AH1 T6 TE0 L4 LE0 SR1 RL2 PP1 DC1 DT0 C0 E2
The GPIB address is set from the front panel.
