• COM3 and COM4 cannot be used for +5V Output.
• Do not connect any pins to COM3 [NC].
• No. 5 pin (GND) for RS-232C (COM1,COM2,COM3, COM4) is the
signal ground. Be sure to connect the GND terminal to the other
unit’s SG (signal ground) terminal.
• Be sure to confirm what settings will be used by the other device
when setting the switches. Failure to do so can result in a unit
malfunction or damage.
• Whenever changing any PS-A switch settings, be sure to first turn
the PS-A’s power supply OFF. Failure to do so can cause a PS-A
malfunction.
• Connect the FG terminal line to the connector cover's PS-A con-
nector attachment screw.
• FG and SG terminals are internally connected in the PS-A. When
connecting to another device, be sure to create an SG shorting
loop in your system.
Use inch type (#4-40UNC) threads to hold the cable's set (attachment) screws
in place.
