I am trying to use the xbeepro 900hp rs232/rs485/usb rf modem as a delivery interface from air to ground one way to display engine telemetry. My data is transmitted via rs422 lines tx+ , tx-. I’ve attached those lines to the tx on the host/transmitter and the rs422 rx on the ground/receiver and the to my display device. I’ve put the dip switchs with 1 up for the 422 operation.
The leds show the host receiver tx blinking rapidly, that transmit is working?
Yes that shows that the radio is receiving the data on the 422 line and transmitting it over the air to the Address listed in the radios DL and DH commands.
