Question:  

What are compatible AxLink cable types?

Answer:

Compatible AxLink cable types include those manufactured by Liberty Wire & Cable Inc., and cables that comply with Category 5 or Belden 8102 standards.

Pre-Manufactured AxLink Cable

Liberty Wire & Cable Inc. manufactures AxLink cable that contains two pairs of conductors:  

Data (AXP/AXM): 22 AWG stranded shielded twisted pair (STP) with a single drain wire

Power (+12V/GND): pair of 18 AWG stranded wire.  

The nominal capacitance between the data conductors is 12.5 pF/ft.  Maximum Overall Cable Distance Using Liberty Wire & Cable Inc. AxLink cable, the maximum overall cable distance between the Central Controller and all external devices for data communication is 3,000 feet with no remote power.  Liberty Cable & Wire Inc. Cables FIG. 4 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.

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.

Ground Shielding

Under normal circumstances ground shielding should not be necessary.  Only use ground shielding when experiencing noise in the line.  The shield connection should only be tied on one end - the Master side. Tying both ends can result in a ground loop.

Tie the ground shield connection to the Master side only​.
