6.4 Odometer Extension Cable
If a SPIDAR NIC-500 is being attached to SmartCart, SmartTow or SmartChariot platform using
an odometer trigger, the odometer cable must now be directly connected to the NIC-500. This
will necessitate the use of an odometer extension cable, pictured below. The cable coming off
the odometer must now be connected to this extension cable. The other end of this extension
cable will be connected to the NIC-500.
