In addition, the breakout box includes a Lemo 7-pin connector to
extend serial communications and/or power on Port 2. Because the
BNC connectors are used to service the event marker and 1PPS
features, pins 4 (1PPS) and 5 (Event Marker) are inactive on the Lemo
connector.
For Port 2 pinouts, see Port 1, 2, and 3 Connectors, page 88. For more
information on 1PPS input and event marker output, see Chapter 11,
Event Marker Input and 1PPS Output.
