we have two ADM3053 CAN transceivers and they are controlled by a NI PXI embedded controller. We would like to use the PXI system as low level gateway.

In this structure the communication between the nodes can't set up. (our opinion due to the wrong ACK - acknowledgement)

We connect the RXD of Transceiver_1 to the TXD of Transceiver_2 and the RXD of Transceiver_2 to the TXD of Transceiver_1.

What could be the problem?
