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 termi-
nals 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 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 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 Out-
put 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/Remote Analog control
(J1-8) function and Setup switch SW1-1, 2 settings.

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 voltage
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.
