Product questions
Does the A1SJ71QC24N1-R2 have RS-422 or RS-485 ports?
No. Both channels on the A1SJ71QC24N1-R2 are RS-232C. The similarly named A1SJ71QC24N1 without the R2 suffix has RS-232C on channel 1 and RS-422/485 on channel 2; do not assume the two modules are interchangeable.
What transmission speeds can both channels use simultaneously?
Both RS-232 channels can operate at up to 115,200 bps simultaneously, subject to a combined limit of 230,400 bps. Available settings are discrete speeds from 300 to 115,200 bps when the modem function is not used.
What connectors and cable distance does the module use?
Each channel uses a 9-pin D-sub RS-232 connector. Mitsubishi specifies a maximum RS-232 transmission distance of 15 m. Choose the mating cable and wiring to suit the connected device and consult the hardware manual.
Can the A1SJ71QC24N1-R2 communicate through a modem?
Yes. The modem function can use either RS-232C interface; the hardware manual specifies full-duplex communication and modem-mode rates from 1,200 to 115,200 bps. Verify the modem and system configuration before ordering.
How can I confirm that this module fits my PLC system?
Fitment cannot be established from the part number alone. Provide the PLC CPU and base-unit model numbers, the existing module label, and the equipment serial number so the system and communication requirements can be checked.
