The transponder must be in maintenance mode for the Installation message to be received and processed, otherwise the
message is ignored.

RS-422 bus will be selected if pins are left unconnected. The pin must be grounded to select RS-232 bus. (See Table 6-2)

Transmit and receive are from the MXS perspective. Connect as appropriate. There must be at least one COM port
connected for control.
