* The matching of wire sizes to equivalent wire gauges are only approximate.
** Recommended cable types for opmal HBUS RS485 performance.
*** Not applicable for PIV or Gallagher mobile credenal reader installaons.
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, operang 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 funcon correctly. The cable length and the number of readers connected
will have an impact on the voltage at each reader.
3 Distancebetweenreaders
The distance separang any two proximity readers must not be less than 200 mm (8 in) in all direcons.
When mounng a proximity reader on an internal wall, check that any reader xed to the other side of
the wall is not less than 200 mm (8 in) away.
