Description
1
RS-232C /RS-485
It is a 9-pin D type male connector. The control commands are
transmitted between remote and PC for remote control.
2 ANALOG
INTERFACE Signal
Connecting Terminal
There are 25 pins signals for APG input/output terminals and
system status signal terminals. See
Appendix A
for detail pin
assignments.
3
System Bus
It is for serial/parallel data transmission.
4
USB
The remote controller uses USB connector to connect to PC for
remote operation.
5 Output terminal
The output terminals of DC Power Supply.
6 Remote Sense
Connector
Connecting this connector to load can compensate the voltage
drop generated due to cable resistance. Be sure to connect the
remote sense connector “+” to the positive output terminal and
“–” connector to the negative output terminal. Do not connect the
remote sense connector to the “+”, “–” output terminal reversely.
7 Current Sharing
Connector
It shares the output current equally when connecting in parallel
and it has to be removed when connecting in series for use.
8 GPIB/ETHERNET
Connector (Option)
The GPIB/ETHERNET bus used by remote controller is
connected to PC via this connector for remote control.
9 AC Power
Connector
It inputs AC power through power line and connects to input
stage through this connector.
10 Functional Ground This terminal is for user to refer to Earth Ground easily.
11 Fan Mask
