This special cable from AiM was developed to connect two ACC3 Analog-to-CAN Converters (sold separately) plus up to 2 more CAN expansions to your MyChron6 dash (sold separately) and to an external power source.
One end has a male 5-pin 712 (screw-in) connector. The other end has two male 5-pin 712 connectors, two female 5-in 712 connectors, and a cable with two unterminated wires for +12V Power In and Ground. A typical connection example would be to plug one of the male connectors into the MyChron6, one male into an ACC3, and the third male into a SmartyCam; the two female would accept an LCU and the standard cable from a second ACC3; the two unterminated wires connect to an external battery to power the network.
Despite its karting roots, this cable can also be used certain in automotive installations as a compact replacement for a 4-port CAN Data Hub.
