The PS-A unit side connector is a D-Sub 9

Interfit Bracket #4-40 (UNC)
• COM2 is an interface for the serial 2 port
type only.
• Do not connect any pins to [NC].
• Connect the FG terminal line to the shell.
• Always connect the #5 SG (Signal
Ground) of the PS-A unit to the
connected device, especially if the
connected device is also not isolated.
Failure to do so may damage the
RS232C/RS422/RS485 circuit.
• FG and SG terminals are internally
connected in the PS-A. When
connecting to another device, be sure
not to create an SG shorting loop in your
system.
COM1
COM1can be changed to RS-232C, RS-422 or
RS-485. (The factory setting is RS-232C.) To
change this setting, open the PS-A unit's FAN
Unit or Memory Slot Cover and set DIP switch
on the circuit board to the desired position.
