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.

NOTE: No internal CAN termination is fitted within the SPEEDBOX MINI, It is essential that the user fits appropriate termination if required. In general, if the SPEEDBOX MINI is at one end of a two node CAN network with a CAN logging device at the other end, then the SPEEDBOX MINI 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.
