NOTE: There is an internal debounce on the trigger input which means that only one edge will be detected during the debounce period (50ms). As such, when triggering on thin laser barrier strips or short button presses it is important to trigger on the first edge which will be seen, otherwise the trigger signal can be missed.
CAN port
9 way D-type male connector. If two CAN ports are present on the front of the unit then they are internally connected in parallel, this makes connecting termination much simpler.

NOTE: No internal CAN termination is fitted within the SPEEDBOX, It is essential that the user fits appropriate termination if required. In general, if the SPEEDBOX is at one end of a two node CAN network with a CAN logging device at the other end, then the SPEEDBOX will need to be fitted with a 120Ω resistor between CAN H and CAN L in the cabling used to attach it to the network

Antenna 1 and 2
SMA 3.3V feed to antennas. On the standard SPEEDBOX and the SPEEDBOX-INS Single Antenna only “GPS A (Main)” is connected. On the SPEEDBOX-INS Dual Antenna (and older dual antenna SPEEDBOX systems) RF 1 is connected to GPS A (Main) and is the rear antenna on the vehicle, RF 2 is connected to GPS B and is the front antenna on the vehicle.
