LCOM line
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 bi-directional communication 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:
•

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.
Bad wiring during installation may break some protection devices.
