Pair

Although the arrows in this diagram showing data flow are bidirectional, and the Adapters and Balun Mate II do support bidirectional data transfer, the direction of flow on the transmit lines (coax TX, twisted-pair pins 1 and 2) will always be opposite to the direction of flow on the receive lines (coax RX, twisted-pair pins 4 and 5). Which signal is input and which is output on either interface will usually depend on the DTE/DCE configuration of the attached devices.
