7. REMOTE AND ANALOG PROGRAMMING

7.1.

Introduction

The rear panel connector J1 allows the user to program the power supply Output voltage and
Output current limit with an analog device. J1 also provides monitoring signals for Output
voltage and Output current. The programming range and monitoring signals range can be
selected between 0-5V or 0-10V using the setup switch SW1. When the power supply is in
Remote Analog programming, the serial communication port is active and can be used to
read the power supply operating parameters.
COM (J1-12), VPGM_RTN (J1-22) AND IPGM_RTN (J1-23) terminals of J1
connect internally to the negative Local Sense potential (-LS). Do not connect
these terminals to any potential other than negative Local Sense (-LS), as it may
When the Isolated Analog Option is installed, do not apply any signals to the non-
isolated VPGM and IPGM (J1-9 and J1-10) pins. All other J1 features may be
used normally. Refer to Section 4.5 for a description of the J1 connector features.

Local/Remote Analog Selection

J1-8 (Fig.4-4) accepts a TTL signal or an Open-Short contact (referenced to J1-12) to select
between Local or Remote Analog programming of the Output voltage and Output current
limit.
In Local mode, the Output voltage and Output current limit can be programmed via the Front
Panel VOLTAGE and CURRENT encoders or via the RS-232/RS-485 port. In Remote
Analog mode, the Output voltage and Output current limit can be programmed by analog
voltage or by programming resistors via J1-9 and -10 (Refer to Sections 7.4 and 7.5). Refer
to Table 7-1 for the Local/Remote Analog control (J1-8) function and Setup switch SW1-1, -2
