HBUS Cable
* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for optimal HBUS RS485 performance.
*** Not applicable for PIV or Bluetooth® enabled reader installations.
**** Tested with 13.6V at start of cable.
Notes:
Shielded cable may reduce the obtainable cable length. Shielded cable should be
•
grounded at the Controller end only.
If other cable types are used, operating distances and performance may be reduced
•
depending on the cable quality.
HBUS allows up to 20 readers to be connected to a single cable. Each reader requires
•
13.6 Vdc to function correctly. The cable length and the number of readers connected will
have an impact on the voltage at each reader.

Distance between readers
The distance separating any two proximity readers must not be less than 200 mm (8 in) in all directions.
When mounting a proximity reader on an internal wall, check that any reader fixed to the other side of
the wall is not less than 200 mm (8 inches) away.
