When the Isolated Analog Option is ins
talled, do not apply any signals to the
isolated VPGM and IPGM (J1
10) pins. All other J1 features
may be used normally. Refer to Section 4.5 for a description of J1 features.
CHAPTER 6 REMOTE ANALOG PROGRAMMING
The rear panel connector J1 allows the user to program the power supply output voltage and current
log device. J1 also provides monitoring signals for output voltage and output current.
ming range and monitoring signals range can be selected between 0
the setup switch SW1. When the power supply is in Remote Analo
g programming, the serial commun
cation port is active and can be used to read the power supply parameters.

lect between Local or Remote Analog programming of the output voltage and current limit.
In Local mode, the output voltage and current limit can be programmed via the front panel VOLTAGE
and CURRENT encoders or via the RS232/485 port. In Remote Analog mod
e, the output voltage and
current limit 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

6.3 LOCAL/REMOTE ANALOG INDIC
2, Item 5) is an open collector output that indicates if the power supply is in
cal mode or in Remote Analog mode. To use this output, connect a pull
source of 30Vdc maximum. Choose the pull
tor so that the sink current will be less than 5mA
when the output is in low state. Refer to table 6
