SN65HVD06: R signal when transmitting

HS FAE Germany
Mastermind 31170 points
Part Number: SN65HVD06

Hello,
how is the receive signal R when transmitting on pin D? (RE = LOW, DE = HIGH)

Customer wants to verify the signal that is transmitted through D, by checking the receive signal at R.

Regards, Holger

    Holger,

    When the RE line is low, the receiver's "R" output will correspond to the logic state of the bus (as per Table 2 in the datasheet).  This is true whether the bus is being driven by the same transceiver or by some other node on the network.  So, what the customer intends to do (verify that the transmitter is working by monitoring the R output) will work.
