    HE-XRC9 deactivates the MJ1 serial port. However, support is provided to select which device is currently active through ladder control. The HE-XRC9 is provided connection to the internal handshake lines of RTS and CTS. As such, the OPEN function block handshake parameter of hardware is functional if the HE-XRC9 is programmed appropriately.

    The factory default setting of these parameters are 9600, 8, N, and 1. It is possible to program the HE-XRC9 for a different baud rate and frame protocol and save those values to non-volatile memory; however, it is left to the user to record those values and set the OPEN function block appropriately.

Modes of Operation   The COM Module can only be in one mode at a time.   Idle Mode When not receiving or transmitting data, the modem is in Idle Mode. The modem uses the same amount of power in Idle Mode as it does in Receive Mode.

Data in the DI buffer is grouped into RF packets (up to 2048 bytes in each packet - refer to PK (Maximum RF Packet Size) Command), converted to RF data and then is transmitted over- the-air until the DI buffer is empty.
