LCOM is the network that connects the 4HD/5HD-HUB units to: QubicaAMF pinspotter interfaces, camera
assembly, Bumper Control units or other LCOM controlled devices (such as XLMP or EDC).
The LCOM network runs through a four-wire cable, with two wires carrying the power and two wires
carrying the communications bi-directional signal.
QubicaAMF supplies 60ft – 20m of LCOM cable for each pair of lanes, enough for a standard installation.
Every LCOM device is exclusively powered through the LCOM line.
The source for the LCOM line on each pair of lanes is the C1 connector on the 4HD/5HD-HUB unit.
The pin out for this connector is:
 +: +18 Volts unregulated;
 B: Communication –;
 A: Communication +;
 -: Common.
The recommended size for LCOM wires is AWG 18 - 0.75mm².
The LCOM power line is protected from a short-circuit by an AUTO-FUSE mounted inside the 4HD/5HD-HUB
unit.
The LCOM communication is protected from electrostatic discharge by special devices mounted on all
LCOM electronic boards.
A bad wiring during installation may break some protection devices.
