CAUTION

COM (J1-12), VPGM_RTN (J1- 22) AND IPGM_RTN (J1-23) terminals of J1

connect internally to the -Sense potential (-S). Do not connect these term inals

to any potential other than -Sense (-S), as it may damage the power supply.

CHAPTER 6 REMOTE ANALOG PROGRAMMING

6.1 INTRODUCTION

The rear panel connector J1 allows the user to program the power supply Output Voltage and

Current with an analog device. J1 also provides monitoring signals for Output Voltage and Out-

put 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 pro-

gramming mode, the serial communication port is active and can be used to query the power

supply settings.

6.2 LOCAL/REMOTE ANALOG INDICATION

Contact 8 of J1 (Fig.4-2, Item 5) accepts TTL signal or Open-Short contact (referenced to J1-12)

to select between Local or Remote Analog programming of the Output Voltage and Current.

In Local mode, the Output Voltage and Output Current can be programmed via the front panel

VOLTAGE and CURRENT encoders or via the RS232/RS485 port. In Remote Analog mode, the

Output Voltage and current can be programmed by analog voltage or by programming resistors

via J1 contacts 9 and 10 (refer to Sections 6.4 and 6.5). Refer to Table 6-1 for Local/Remot e

Analog control (J1-8) function and Setup switch SW1-1, 2 setting.

6.3 LOCAL/REMOTE ANALOG INDICATION

Contact 21 of J1 (Fig. 4-2, Item 5) is an open collector output that indicates if the power supply is

in Local mode or in Remote Analog mode. To use this output, connect a pull-up resistor to a volt-

age source of 30Vdc maximum. Choose the pull-up resistor so that the sink current will be less

than 5mA when the output is in a low state. Refer to table 6-2 for J1-21 function.
