Operation Instructions for the
Equestrian/Course Speed-Timer
 The Beam consists of two parts, the Receiver and Wireless Transmitter. The system also comes with a large display unit that connects to the Receiver.
The Transmitter sends a narrow invisible Infra Red Beam to the Receiver on a continuous bases. Any interruption of the Beam between the Transmitter and Receiver sends a code to the Display that can be used to start or stop the Display program. The Receiver is plugged into the RJ11 Connector on the bottom of the Display with the 50-foot (15-meter) included cable. The remote transmitter is a wireless connection between the transmitter and receiver. Both the transmitter and receiver have standard tripod screw mounts for attachment to photo style tripods and both use individual 9-volt alkaline batteries. The Receiver shares the power of the Display and can also be used in conjunction with the 110-volt AC adapter provided with the system.
Alignment between the Transmitter and Receiver is accomplished by first turning on the Transmitter and positioning it in a location from 3 to 200 feet (1 to 60 meters) from the Receiver. Plug the cable from the Beam Receiver into the RJ9 Connector located on the bottom of the Display and turn the main switch on the Display, to "On". Point the Receiver at the Transmitter. When alignment is correct a red LED on the back of the Receiver will go out indicating alignment. No further setup is required.
Uses:
Stand alone Display with one Beam and the same entrance and exit for the event.
Have the receiver and transmitter turned on and aligned as above. The Display will cycle, first displaying "rdy" on the Display, then "0.000". Passing between the Transmitter and Receiver will start the clock running, then passing again through the Transmitter and Receiver will stop the clock. This finish time will remain on the display until the next competitor breaks the beam to restart. There is no need to dismount to reset the timer, and can easily be used without assistance or timekeeper intervention.
Display with two Beams with different entrances and exits for the event.
Plug the optional Y Connector into the Display, then the start Beam into one side of the Y Connector. Layout the required length of optional cable to the finish location and plug the cable into the second outlet on the Y connector and the back of the remote receiver. Turn the main switch on the Display to on. Point the Receiver at the Transmitter, when alignment is correct a red LED will go out on the back of the Receiver indicating alignment. Align the remote Beam in the same manner. No further setup is required. Note: an optional Manual Start or Stop switch can be substituted for either the start or stop location.
As soon as the competitor break the beam at the beginning of a run, the time on the display starts counting up. This allows the competitor, judges and spectators to see the elapsed time throughout the run until the beam is broken again, freezing the display at the total elapsed time.
