Open the box of the WASPT device.
Connect telemetry lines A and B to connector J9

We recommend using a twisted cable with minimum
section of 0.22mm²/0.8in² (AWG24).
If the receiver is connected to one of the head
communication channels RS-485, the line must be
terminated (SW8 column, Tab. 1, page 3).
Insert the DTWRX board in the specific J8 housing
and close the box of the WASPT device.
