Table 10.2 gives pinout information for the power/serial data cable
(PN 32345), which is supplied with the Trimble R7 receiver.
Note – Table 10.2 assumes that the cable is attached to the connector
labeled Port 1 or Port 3.
10.3Event Marker/1PPS Cable
The event marker/1PPS cable shown in Figure 10.3 provides a breakout
box with two BNC ( female) connectors for providing 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 Trimble R7 receiver, such as a
photogrammetric camera, to the BNC connector labeled Event Marker
on the breakout box.
