EARTH Connection
Connect the IXP110 Controller to a good EARTH point. Using the Power Input Port,
connect the EARTH Lead to the 'ETH' Terminal. Mains EARTH can be used, but
electrical noise may exist.
Antenna Readers
Antenna Reader Distance
The ideal cable distance between the IXP110 Controller and its Antenna Reader
ranges between 2 m to 16 m (7 ft to 53 ft). Optimal performance is not guaranteed
outside of this range. Achieve optimal performance using a good quality shielded multi-
strand **3-pair twisted cable. The cross-sectional area of the cable must not be less
2
than 0.2 mm
(0.0003 in
NOTE:
**When installing an ImproX RA, use 1-pair twisted cable.
Cable Specifications
The cable specifications should be similar to the following:
Conductor Resistance:
Capacitance, Core to Earth:
Capacitance, Core to Core:
Distance between Antenna Readers from the SAME Controller
To avoid mutual interference install the Antenna Readers no closer than 150 mm (6 in)
apart.
Distance between Antenna Readers from DIFFERENT Controllers
To avoid mutual interference install the Antenna Readers no closer than 500 mm
(20 in) apart.
Arc Suppression
Snubber devices are recommended for EMF Flyback and Arc Suppression when
driving an inductive load with the Relay, see Figure 2.
