Event Marker/1PPS cable
The following cable is available:
P/N 36451-02: Cable ASSY EVENT MARKER/1PPS
Used for power input to port 4, event marker in and 1PPS output.
The event marker/1PPS cable provides a breakout box with two BNC (female) connectors for 1PPS input and event marker output.
Connect a device that accepts 1PPS output pulses to the BNC connector labeled 1PPS on the breakout box. Connect a device that outputs event marker pulses to the receiver, such as a photogrammetric camera, to the BNC connector labeled Event Marker on the breakout box.
In addition, the breakout box includes a Lemo 7-pin connector to extend serial communications and/or power on port 4. 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 4 pinouts, see Lemo connectors (port 3 and 4).
The following pinouts are for the event marker/1PPS cable. The event marker/1PPS cable is used only with the receiver connector Port 4 ( for event marker output).
