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, operang 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 funcon correctly. The cable length and the number of readers connected
will have an impact on the voltage at each reader.

The distance separang any two proximity readers must not be less than 200 mm (8 in) in all direcons.
