There are three connectors on the rear of the system which are used for timing, in addition to the Trigger Port which is located in the main port compartment.
The Active Loop Port and Expansion port are both protected by the rubber port cover for transport or when not in use, and the Active Timing Antenna should also be folded down into the slot when not in use to protect it from damage.
Active Loop Port
The Active Loop Port (two red banana jacks) is used to connect a Loop Cable when using Ubidium as an Active System.
Ubidium can support loop cables between 5 meters (~16 ft) and 60 meters (197 ft) in length, which should be setup with a width between 30cm (11 inches) and 60cm (22 inches).
Longer cables may result in power degradation which will inhibit the ability of the system to provide 100% Loop Power.
 |
Only connect RACE RESULT Loop Cables to the Active Loop Port. Do not connect any external power source through the Active Loop Port. |
Active Timing Antenna
The Active Timing Antenna is used for 2.4Ghz with Active Transponders when using Ubidium as an Active System.
When not in use this should be folded down into the storage slot on the case of the system, it is not necessary to disconnect this antenna.
Trigger Port
The trigger port (black and blue banana jacks) can be used to connect to third-party timing devices to either receive or send timing impulses. These are a pair of standard 4mm banana plugs.
Devices used to record impulses should normally open and close the circuit to create the trigger, the impulse must be LOW for a duration of at least 1ms (0.001s). If recording multiple consecutive triggers, then the impulses must be 10ms apart (0.01s).
The trigger port cannot be used to connect a Loop Cable for timing.

Expansion Port
The expansion port is used for connecting the Ubidium Ground Antenna.
