2. Electrical Installation
The Antenna Controller power requirements are 12Vac/dc@500mA.
This power supply, protected by a 0.5A fuse on the reader, does not include supply to
external outputs.
Maximum consumption, including supply to external outputs, is 1A
Power to the Antenna Controller can be supplied in three different ways:
a) 12Vac, rectified by a diode bridge on the reader.
B) 12Vac from a transformer with two 12Vac outputs and a center point,
Important note! For this option the two negative polarity diodes of the diode bridge
rectifier D29 and D30 (see Figure 0-1) must be removed.
c) 12 regulated/non regulated DC voltage.

Twisted pair wire can be used for distances of up to 20 centimeters.
At any distance ranging between 20 cm. and 1.2 m., coaxial cable should be used.
For distances from 1.2 m. to 33 m. coaxial cable is used, in half-length multiples of the
wavelength. See table 3-1 for half- wavelength calculations.

3. Antenna Tuning
3.1 Factory Tuning
The antenna is factory tuned and does not require customer adjustment. If it becomes
necessary to tune the antenna, the following sections describe the process.
3.2 Antenna Tuning Equipment
!
!!
! DVM - Digital Voltmeter (mV range).
!
!!
! DVM adapter Cable (see Figure 3-1).
! Non-conductive ceramic screwdriver.
Figure 3-1: DVM Adapter Cable
3.3 Tuning Procedure
Antenna tuning should be performed after the antenna has been installed in its final
position. This will ensure that the tuning will compensate for the effects of nearby
metallic objects.
To tune the selected antenna, follow the procedures below:
1) Choose the transmitter of antenna to be tuned by removing it’s SL jumper
( for constant RF transmission) and by placing all other SL jumpers in
OFF position
2) Connect Antenna coax cable or twisted wires to the selected antenna
terminal block on the Reader (Figure 0-1)
3) Connect the DVM adapter Cable to connector P5 (Figure 0-1).
4) Apply power to the Reader.
Note: Do not touch the Antenna.

4) Using the ceramic screwdriver, turn the antenna matching capacitor to
reach maximum capacity.

5) Turn the antenna matching capacitor slowly counter-clockwise (CCW)
until the maximum DVM reading is achieved (approximately
110 - 130 mV).
Note: If voltage is highest when the matching capacitor is at the position of its
maximum capacitance, replace existing Cp capacitor with one of the next
higher value. If voltage is highest when the matching capacitor is at the
position of its minimum capacitance, replace the existing Cp capacitor
with one of the next lower value (see Table 4.1).
Next, repeat steps 4 & 5.

6) Turn the Antenna matching capacitor clockwise (CW) to reduce the
reading by 10mV to 15 mV (i.e. if the maximum reading was 120mV, the
final reading should be 105mV to 110mV).
7) Slowly move a metallic object close to the Antenna assembly (up to 2 cm
from the Antenna). The reading should rise slightly towards the maximum
before it drops, when the metallic object is placed very close to the Antenna
assembly.
Note: If the reading does not rise, but only drops, readjust CCW to reduce
reading by 10 - 15mV, then re-check with a metallic object.
3.4 Antenna Tuning Final Check and Assembly
At the completion of the procedures in Section 5-3, perform the following procedures:
1) Return all SL jumpers to MT position.
2) Check Antenna operation with a card.
3) Cover and seal Antenna matching capacitor tuning opening with special
non-corrosive RTV (“Rotacil 1112”, or equivalent).
3.5 Procedure for Choosing Coil - Ls
- Refer to section 1.1 for connector and jumper positions on card.
1) Connect a 50Ω resistor, to simulate antenna load, by applying a jumper to
the selected transmitter.
(J1 - Xmtr. #1, J2 - Xmtr. #2, J16 - Xmtr. #3 or J19 - Xmtr. #4).
2) Remove the SL jumper of the selected transmitter (for constant RF
transmission) and place all other SL jumpers in OFF position
3) Connect DVM to connector P5.
4) Apply power to card and register the DVM reading.
5) Remove 50Ω resistor jumper (see step #1) and connect the selected antenna
cable to the selected antenna terminal block.
6) Perform antenna-tuning procedure. (Refer to section 1.1).
7) If DVM reading at maximum point is lower by more than 10 mv with
antenna than with 50Ω resistor, replace Coil Ls with one of the next lower
value .(i.e. 3.9µH → 3.3µH )
8) If DVM reading at maximum point is higher by more than 40 MV with
antenna than with 50Ω resistor, replace Coil Ls with one of the next higher
value. (i.e. 3.9µH →4.7µH )
9) After replacing Coil Ls, repeat procedure from step 6.
10) Return all SL jumpers to MT position.

Power Supply
A single Site Controller supplies power to a limited network of Antenna Controllers.
Power supply to all system elements should take into consideration the total and
distributed current loads according to the routing topology of the supply lines with
the associated voltage drops. Class 2 limits the maximum allowed current via field
wiring to 8A. This actually means a maximum rating of about 5A for the fuse on the
transformers secondary circuit.
6.3 Transformer
The Site Controllers transformer is intended to convert the incoming AC power
(115/230) to 12VAC @ 3.3A used to power the Site Controller GBI 2.0 board and a
limited number of Antenna Controller units.
6.4 Fuses
The Site Controller’s AC supply system is protected by three fuses, one on the
transformer’s primary circuit and two (in series) on the transformer’s secondary
circuit.
To comply with class 2 requirements, the 5A slow blow fuse on the transformer’s
secondary circuit is non-replaceable. The 3A fuse placed in series with this 5A
fuse is replaceable and is intended to blow before the 5A fuse.
