AXlink Wiring Considerations

Liberty Cable & Wire Inc. cables

FIG. 3 shows a wiring diagram for AXlink cables manufactured by Liberty Cable & Wire Inc. The

PWR connection shown in the diagram is only used when supplying 12 VDC via the AXlink cable.

The PWR connection should not be used when a local power supply is connected directly to the

external AXlink device.

Belden 8102-compliant cables

Belden 8102-compliant cable contains two single twisted pairs (STP) of 24 AWG with a single

drain wire. The nominal capacitance between conductors is 12.5 pF/ft. Using Belden 8102-

compliant cable for AXlink data communication, the maximum overall cable distance between the

Central Controller and all external devices is 3,000 feet with no remote power.

FIG. 4 shows a wiring diagram for the AMX-approved Belden 8102 AXlink cable. The PWR

connection shown in the wiring diagram is only used when supplying 12 VDC via the AXlink

cable. The PWR connection should not be used when a local power supply is connected directly to

the external AXlink device.

Category 5-compliant cables

Category 5 cable contains four unshielded twisted pairs (UTP) of 24 AWG solid wire. The nominal

capacitance between conductors is 15.0 pF/ft. Using Category 5-compliant cable for AXlink data

communication, the maximum overall distance between the Central Controller and all external

devices is 1,000 feet. If the installation site's wiring conforms to EIA/TIA 568 Category 3

standards, AXlink data communication will function properly. However, power (PWR) cannot be

used with EIA/TIA 568-Category 3 standard cable because of connector types and punch blocks.

FIG. 5 shows a wiring diagram for Category 5-compliant cable used for AXlink data

communication. The PWR connection shown in the wiring diagram is only used when supplying 12

VDC via the AXlink cable. The PWR connection should not be used for EIA/TIA 568 cable

installations.
