Wiring
Power supply must be connected to the first (leftmost) device. When devices are
connected, autoaddress procedure must be started using HIQ Configurator.
Devices inside switchboard are addressed sequentially, from left to right. Devices
outside of switchboard (field modules) are addressed in order of ascending serial
numbers - lowest serial number gets the first address, second lowest the second,
and so on.
Inside the switchboard, bus is connected with 4x flat cable and RJ9 connectors.
Outside the switchboard, bus is connected with a unshielded twisted-pair cable
and orange push-wire terminals.
Maximum bus length is 100 meters. Up to that length, bus can be connected with
no special rules, branching is allowed. Longer bus (up to 300m) is possible, but
cable must be connected in line (no branches/trunks), and last device must be
terminated with a 120ohm resistor between CANL and CANH.

Bus wiring
1. Take one ingoing and one outgoing wire together,
and remove insulation for about 10-12mm.
2. Crimp wires together into a ferrule.
3. Wrap wires together for a few centimeters.
4. Push ferrules into clamps.
