Keyboard & Rotary Control
All functions, including the selection and set-up of the remote control interfaces, can be set from
the keyboard. The rotary Jog control can be used to adjust output voltage and current settings in a
quasi-analogue mode. The output to be controlled is first selected with the appropriate Control key.

Analog Remote Control and Monitoring
Non-isolated inputs and outputs to set voltage and current limit and to monitor actual output volt-
age and current. These signals are referenced to the negative output and have a range of 0 to 10V
or 0 to 5V (selectable via the keyboard). Note that the analog control voltage is digitised within the
power supply.

Logic Control Input and Output
LOGIC IN is a rear-panel opto-isolated input that is activated at an input current greater than
approximately 1mA. User can set LOGIC IN (via the keyboard) to enable the output, disable the
output, or be ignored when it is activated.
LOGIC OUT is an isolated rear-panel open-collector output that will sink up to 2mA when activated
(‘switch closure’); the maximum voltage that can be applied to LOGIC OUT is 30VDC. User can set

The QPX1200SP offers full remote control and read-back using RS-232, USB, GPIB or LAN
(compliant with LXI class C). All interfaces are at ground potential and opto-isolated from the
output terminals. The QPX1200L has USB, RS-232 and LXI compliant LAN only (no GPIB).
RS-232
Standard 9-pin D connector. Baud rate 9,600.
USB
USB 2.0 connection (backwards compatible with USB 1.x). Operates as a virtual COM port.
GPIB (IEEE-488) - QPX1200SP only
The interface conforms with IEEE-488.1 and IEEE-488.2.
Ethernet (LAN)
Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to Local
Area Network or direct connection to a single PC.
