For the TCAN1046A footprint, the TXD inputs (pin 1 and 5) of the transceiver; TXD1 is routed to pin 6 of J11, or TP13. The signal path to the J11 header is pre-installed with a 0-Ω series resistor, R22. TXD2 is routed to pin 10 of J11, or TP14, and the signal path to the J11 header is pre-installed with a 0-Ω resistor, R28.

For the TCAN1046AV foorpint, the TXD inputs (pin 1 and 6) of the transceiver; TXD1 is routed to pin 6 of J22, or TP29. The signal path to the J22 header is pre-installed with a 0-Ω series resistor, R50. TXD2 is routed to pin 10 of J22, or TP31, and the signal path to the J22 header is pre-installed with a 0-Ω resistor, R54.
