Introduction
All Maple Systems HMIs programmed with EBPro (EasyBuilder Pro), including every cMT X Series and cMT Series model, are compatible with a Mitsubishi A173UH/A2A/A2U/A2AS/A2USH/A3U. Configure your Controller and HMI/cMT with the following parameters to establish reliable communication.
Supported Series: Mitsubishi A173UH,A2A,A2U,A2AS,A2USH,A3U

Pass-through
When the PC reboots or virtual com port is reinstalled, it needs to be re-initialized for pass-through.
Wiring Diagram
Use the RS422 to RS232 PLC programming cable (shown as follows).
NOTE: Due to hardware limitations, this PLC is not supported by HMI models without RTS/CTS.
NOTE: The serial port pin assignments may vary between HMI models.
