Remote Analog Programming of Output Voltage and Current Limit
Release 1.1 61
Remote Analog Programming of Output Voltage and Current Limit
Remote analog programming allows control of the power supply’s output voltage
and/or current limit to shift from local operation at the front panel voltage and current
controls to external analog sources. As you vary the external programming source,
the power supply’s output varies proportionally over its output range.
Using remote analog programming requires that you reset switch S1 and make
connections to the J1 connector on the power supply’s rear panel.

Options
See Table 4.2 for a summary of the options available to you for programming output
voltage and current limit using an analog source.
Table 4.2 Remote Programming Options
Select Remote Control Function
The REMOTE CONTROL options allow you to select an interface for remote
control. Before selecting a remote control source, be sure to set up each input using
the appropriate S1 settings.
Remote control functions are listed here along with their respective programming
interfaces:
• Analog V & I: Voltage and current programmed via the analog interface
(LCL/RMT button is ON or S1-5 and S1-6 are ON at rear panel)
• Analog V: Voltage programmed via the analog interface; current programmed
via front panel
(LCL/RMT button is OFF and S1-5 is ON at rear panel)
• Analog I: Current programmed via the analog interface; voltage programmed
via front panel
(LCL/RMT button is OFF and S1-6 is ON at rear panel)
Voltage source programming is selected at rear panel switch S1: S1-5 and/or S1-6
are ON and S1-1 and S1-2 are OFF.
