4. REMOTE OPERATION
4.1 Introduction
The rear panel switches and connector on the power supply allow you to program the supply with an analog
device or to output readback signals. This section covers the following topics.
•
Section 4.2 explains how to use the programming and monitoring selection switch and connector.
•
Section 4.3 contains procedures for remote analog programming of output voltage and current limit
with 0-5V and 0-10V voltage sources and 0-5k
Ω
and 0-10k
Ω
resistances.
•
Section 4.4 shows the connector and switch settings for using calibrated readback signals for output
voltage and output current with selectable 0-5V or 0-10V scales.
Isolated Programming . The four-channel Isolated (ISOL) Programming Interface is an internal card which is
ordered as an option. It allows remote programming and readback of the power supply’s output voltage and
current limit with 0-5V analog signals at a different potential relative to the power supply's output. The ISOL
Interface is described in Section 4.5.
Remote Digital Programming . You can operate the power supply from a computer if you have had the
GPIB or RS-232 Interface card installed as an option. Refer to the separate interface manual for all setup and
operation instructions for remote digital programming.
4.2 Switches and Connector Used for Remote Programming and
Monitoring
Use the rear panel SW1 Programming, Monitoring, and Shutdown Select switch and the rear panel J2
Programming and Monitoring connector to choose among several remote programming and monitoring options.
This section lists the functions of each of the switches and the connector terminals and provides you with the
procedures for resetting them.
4.2.1 Rear Panel SW1 Switch
The SW1 Programming, Monitoring, and Shutdown Select switch is an 8-position piano DIP switch located on
the power supply's rear panel. See Figure 4.2-1. The SW1 switch enables you to choose:
•
Resistive programming of output voltage or current limit
•
Output voltage and current limit programming scales
•
Output voltage and current monitor scales
•
Remote shutdown circuit logic
•
Over temperature shutdown mode
