* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for optimal HBUS RS485 performance.
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 at
least 9 Vdc to function correctly. The cable length and the number of readers connected
will have an impact on the voltage at each reader.
