Mitsubishi FX1N-422-BD RS422 interface Board
Introduction to Mitsubishi FX1N-422-BD
The RS-422 communication board FX1N-422-BD (hereafter reaferred to as "422BD") is connected to the FX1S/FX1N
Series PLC basic unit, and used as a connection port for a programming tool (such as the GOT Series, the ET Series,programming tool FX-10P/20P or personal computer).
For example, by using the 422BD, two GOT Series units can be connected to the FX1S/FX1N Series PLC, or the GOT Series unit can be connected to a programming tool (such as FX-10P, FX-20P or personal computer). However, a programming tool can be connected to only either one between the connector built in the PLC and the connector of the 422BD.
Only one function expansion board can be connected to one PLC basic unit. Accordingly, the 422BD cannot be used together with the FX1N-485-BD or the FX1N-232-BD.

Installation of Mitsubishi FX1N-422-BD
Make sure to turn off the power before installing the 422BD.
A) Communication board 422BD (function expansion board)
B) Connector for optional equipment
C) M3 screw to fix board (2 pieces) (offered as accessories of board)
D) Top cover for board (offered as an accessory of board)
E) M3 screw to fix top cover (offered as an accessory of board)
Note: This screw cannot be removed.
• Plug the communication board A) in to the connector B).
• Fix the board to the basic unit with two M3 screws C). (Tightening torque: 0.3 to 0.6 Nm)
• Remove the top cover of the basic unit, and attach the top cover for board D) instead.
During attachment, remove D)’ with a nipper, etc. so that the connector of the board is exposed.
• Fix the top cover with the M3 screw E). (Tightening torque: 0.3 to 0.6 Nm)
• When the FX1N-5DM is used also, refer to the handy manual offered with the FX1S/FX1N Series PLC main unit.
• Only one function expansion board is available for one FX1S/FX1N Series PLC basic unit. Never stack up two or
more function expansion boards. (Even if they are stacked up, they do not function at all.)
