ALARM OUTPUT
Isolated rear-panel open-collector output signal. User can select output to be activated for either
OVP, OCP, Overtemperature or Sense miswiring, or for any of those four faults.
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.
INTERFACES (XDL 35-5P & XDL 56-4P only)
Full remote control facilities are available through the optional RS232, GPIB and USB interfaces.
Setting and readback resolutions are the same as for the Output and Meter specifications
respectively.
RS232:
Variable Baud rate, 19200 Baud maximum. 9-pin D-connector. Single
instrument or addressable RS232 chain operation.

USB:
Standard USB hardware connection.
Remote Command
Processing Time:
Typically <80ms between receiving the command terminator for a step
voltage change at the instrument and the output voltage beginning to
change.
