It uses an 8-pin MINI-DIN female connector and communicates half-duplex at baud rates from 9600 to 115200 bps. The maximum transmission distance is defined by the GOT's specification, not by the board itself — so the cable run limit depends on the HMI model at the other end. ## No isolation — ground-loop awareness needed The communication line is not insulated from the CPU module, meaning there is no galvanic isolation between the RS-422 signals and the PLC logic. In an environment with large drives or high common-mode voltage, this can couple noise into the serial link unless the ground reference is shared cleanly.","metaTitle":"Mitsubishi Electric FX5-422-BD-GOT Serial Comm Board, RS-422","metaDescription":"Mitsubishi Electric FX5-422-BD-GOT serial communication board for MELSEC iQ-F series.
