Overview
DAG cards have an 8-pin RJ45 connector with two bi-directional RS422
differential circuits, A and B. The PPS signal is carried on circuit A, and
the serial packet is connected to the B circuit.
Pin Assignments
The 8-pin RJ45 connector pin assignments and plugs and sockets are

Out-pin Connections
Normally the GPS input should be connected to the A channel input, pins 3
and 6. The DAG card can also output a synchronization pulse; used when
synchronizing two DAG cards without a GPS input. Synchronization
output is generated on the Out A channel, pins 1 and 2.
Ethernet Crossover Table
A standard Ethernet crossover cable can be used to connect the two cards.
