warning

Use caution while working on the cab roof or standing on exterior surfaces. Surfaces may be uneven or slippery and hardware or harnesses may present tripping hazards. Contact a local equipment dealer for additional information or assistance with working on the roof or from an elevated position on a specific make and model machine.

  1. Connect the combine roof cable 12-pin DTM plug intended for Port A of the Trimble 372 receiver into the 12-pin DTM receptacle labeled "A" on the adapter cable.

  2. Connect the 12-pin DTM plug intended for Port B of the combine roof cable into the 12-pin DTM receptacle labeled "B" on the adapter cable.

    Note:  If there is already a connector on the machine intended for Port B of the 372, plug it into the "PTB" connector on the combine roof cable.

  3. Connect the 12-pin DTM plug labeled "Port 2" into the center connector in the Trimble 392 receiver.

  4. Connect the M12 connector labeled "Port 3" into the right connector of the Trimble 392 receiver.

    Note:  If using an RTKClosed Real-time Kinematic radio, do not plug the M12 connector from P/N 115-0172-668 port 3 of the 392. Instead, plug the RTK radio into port 3 of the 392.
