11 USING DIGITAL COMMUNICATION INTERFACE FOR REMOTE CONTROL
If a digital communication interface has been installed in place of the standard board, the PS-A series unit can be
uter (hereinafter "PC") or sequencer via a USB, GP-IB, or RS-232C.
e has a local bus, a single PC or seque
ontrol multiple PS-A
series units.
The optional digital communication interface boards (referred as “digital IF board” hereinafter) for the PS-A series are
as follows:
●
IF-70GU: Used with GP-IB and USB digital communication interfaces. Can be connected to a PC for remote
control.
●
IF-71RS: U
ication interfaces that are compatible with RS-232C. Can
nected to a PC or
sequencer for remote control.

CN2
Short-circuits the frame GND and signal GND of GP-IB and USB.
CN 2 is used to eliminate ground loops in noisy environments.
CN3
Connects to the terminator of the local bus and the internal bus when the circuit is closed. In
the local bus, a terminator is required for the power supply units at each end of the signal line
or for stand alone.
CN4
Switches operation between the GP-IB and USB.
The GP-IB operates when the circuit is closed, and the USB operates when the circuit is open.
