Ordinarily you’d be correct with Tx goes to Rx and vice versus if cabling from receiver to screen. However in this case the OP was making an adapter cable to swap the 372 receiver with a Novatel receiver. Therefore in his wiring convention Tx should by rights go to Tx and Rx should go to Rx (unless of course Trimble and NovAtel have different data direction conventions for a Tx pin for example).As robt suggested have you simply tried swapping round the Rx & Tx wires on RS232 plug?
This shows the transmitting port (Tx) from the deutsch plug connected to the transmitting port (Tx) on the NovAtel, when usually the transmitting port (Tx) is connected to the receiving port (Rx) and vice versa
Rs232 Tx (out)- com1 RxD (in)
Rs232 Rx (in) - com1 TxD (out)
In any event a quick swap of the Tx and Rx was tried I believe but to no avail. It’s more than likely a baud rate mismatch - but this requires a bit of laptop work with some terminal software to reprogram the NovAtel baud rates.
