Preferred Practices
Mounting location and positioning are very important to this unit’s correct operation.
Read and understand the information in “Access Control Reader Location” before you
begin the installation.
The Antenna is very sensitive to its mounting location while the Controller Module is
not. Additionally, you cannot extend the cable joining the Controller Module and
Antenna. So, mount the Antenna in the best location; and then install the Controller
Module in the best location within a 10 ft. (3 m) radius.
NOTE: Do not alter the Antenna cable length.
Record the location and serial number of the ACR for later inclusion in the floor plan.
Access Control Reader Location
When mounting the ACR, you must plan the best location for the Antenna and the
Controller Module.
Antenna Location Considerations
The Antenna is a tuned circuit: When selecting a mounting location, consider the
Antenna proximity to metal surfaces.
Optimally, mount the Antenna at least 6 in. away from any metal surface such as: metal
studs in the wall, metal frames around doors, air ducts, or conduit and plumbing inside
the walls.
Mount the Antenna to the right of persons approaching the controlled access point as
the microchip is usually implanted in the right arm.
Antenna Height
The ACR should accommodate people of different heights without requiring them to
stoop or stretch. Mounting the Antenna to suit the widest range of people is very
important.
Figure 3 LF Field Shape and Dimensions, shows a side view of the Antenna and the
extent of the LF Field. The field is greatest at the point labelled “Center of LF Field”.
When mounting the Antenna, the aim is to place the Center of LF Field at the same
height as the implanted microchip.
Specifications
The Access Control Reader (ACR) is a Controller Module and an Antenna joined by a
10 ft. (3 m) cable. The device reads the implantable VeriChip™ microchip. The ACR can
work as: a stand-alone reader, an Integrated access control, or part of a VeriGuard™
system.

Wiegand
In Integrated operation and Network operation, the ACR sends microchip information
in standard 26 bit format Wiegand. This is an unacknowledged one-way
communication. Third-party software that receives this data must ensure correct
reception.
RS232
An RS232 port provides connection to a PC running a terminal emulation program
such as HyperTerminal® which is shipped with the Microsoft® Windows® operating
system.
Set the terminal as follows: one stop bit, no parity, baud rate 19200.
This is an unacknowledged one-way communication. Third-party software that
receives this data must ensure correct reception.
System Integration
In network mode, the RS485 network is connected to an Area Controller Hub
Sub-Network. Be sure to record the serial number and location of the Access Control
Reader for node location entry. Refer to the system installation manual for system
installation and commissioning.
Installation and commissioning is completed by the competent contractor or a
competent facility personnel. Following commissioning, no user adjustments are
required at the Access Control Reader during operation.

Communication Overview
The ACR sends microchip identification numbers through the Wiegand and RS232
ports and communicates via an RS485 network.
RS485
As part of a VeriChip RFID system the ACR sends the microchip identification number
to the Hub and to the application server using VeriChip’s proprietary RS485
communication protocol. The VeriChip RFID system issues commands to the ACR and
other components based upon its inputs and configuration.

4 Apply power to the ACR.
5 Notice the current measured by the ammeter. Values may range from 50 mA to
360 mA.
6 Start at the right hand #4 DIP switch. Turn it ON and OFF and record the position
which caused the greatest current and the ammeter reading. Continue to test all
the combinations of switch positions. Table 5, following, has been provided for you
to record your measurements.
7 Select the switch combination that causes the greatest current.
8 If two settings produce the same values, use either setting.
9 You have now tuned the Antenna for the best possible performance in its current
location. You must now re-check its performance using a microchip. If the
detection zone is large enough, replace the label covering the tuning DIP switch.
End of Procedure
All three communication channels are active in Network mode. This allows the ACR to
output microchip identification numbers to third party systems through both the
RS232 and Wiegand ports while continuing to function as part of the VeriGuard
security system on the RS485 network.
In network operation, the ACR is configured through the VeriChip application.
Integrated Mode
When operated in Integrated Mode the ACR can automatically monitor a single access
point. When the ACR reads a VeriChip implantable microchip, it transmits the
microchip identification through the RS-232 and Wiegand ports.
Selecting the operating mode is the first step of the installation procedure below.
Installation
Installation of the ACR consists of several steps. The first step is to select the operating
mode.
Selecting Integrated or Network Mode
The operating mode can be selected using two jumpers: J4 and J5. Both jumpers are
found in the middle of the Controller Module circuit board. Both jumpers have two
pins and a single jumper which can be used to connect the pins.
To select Integrated Mode or Network Mode:
1 Open the Controller Module by removing the four screws in the top of the case.
Locate the jumpers.
2To select Integrated Mode: Connect both J4 and J5 with jumpers.
3To select Network Mode: Remove the jumpers from J4 and J5. Store the jumpers
by placing them on only one pin of each pair.
4 Close the Controller Module.
End of Procedure
Surface Mounting on a Wall
To mount the ACR to a wall surface:
If, after tuning the Antenna, the ACR detection zone is still not adequate, you must
consider modifying the current location; or, selecting another location for the ACR.
Modifying the current location could include:
Moving the Antenna cable further from the Antenna.
Removing any metallic objects near the Antenna.
If you move the Antenna to another location, you may need to retune the Antenna.
Page 15 PN: 981-000293-000 R1.3
1 Once you have chosen a location for the Antenna, use the supplied mounting
template to mark the location of the four mounting holes and one cable entry
hole.
2 Drill the appropriate size holes for #8 screws (4.17 mm) and suitable mounting
hardware for the wall material.
3 Drill the appropriately sized hole for the Antenna cable.
Page 8 PN: 981-000293-000 R1.3
Installation Guide: Access Control Reader Installation Guide: Access Control Reader
4 Feed the cable connector through the hole first and draw the cable up to the
Controller Module. Do not connect the Controller Module at this time.
5 Mount the Antenna to the wall using mounting hardware suitable for the wall
material.
NOTE: Do Not allow the cable to hang within 4 in.
(10.2 cm) of the Antenna back.

7 The cable may be loosely coiled. Tightly coiling the cable may damage it. Use a
maximum of three turns over the entire cable length.
6 Route the cable away from the Antenna.
Ensure the cable does not kink and does
not contact any electrical wires or sharp
surfaces.
Figure 6 shows an incorrect method of
cable routing. The metal shield of the
cable will detune the Antenna when the
cable and Antenna are within 4 in. of
each other.
Figure 7 shows two correct methods of
routing the cable. The method on the
right is better than the method on the
left as it draws more of the cable further
from the Antenna.
Figure 8 is a variation of Figure 7. In
Figure 8 the cable is led up and then in a
horizontal direction either to the left or
right. This again draws the cable away
from the Antenna.
Use the following procedure to test the detection zone size.
To test the detection zone size:
1 Bring a VeriChip™ implantable microchip slowly towards the surface of the
Antenna. When the microchip signal is first acquired, the Antenna LED will flash
and the Antenna buzzer will beep. When the signal is acquired, note the distance
between the microchip and the Antenna.
2 Move the microchip a few feet away from the Antenna and wait for more than
12 seconds. Repeat Step 1.
Once the microchip signal has been acquired, the ACR will not indicate signal
acquisition again until the microchip is out of range for more than 12 seconds.
3 Repeat the above steps several time to find the size of the LF Field.
End of Procedure
Tools
You will need:
an ammeter capable of reading DC milliamperes
a small tipped tool such as a small screwdriver
a power source for the ACR. This must supply 500 mA @ 24 VDC.
Tuning Overview
Tuning increases Antenna efficiency and creates a larger LF Field. The increase of
Antenna efficiency is measured by the ACR current draw. When the ACR current peaks,
the Antenna is tuned.
Tuning is controlled by four small on-off DIP switches. You must select the switch
combination that causes the greatest current draw.
To Tune the ACR:
1 Mount the Antenna in location. Arrange the Antenna cable in its final position.
Connect the Antenna cable to the controller. Place an ammeter capable of
measuring DC mA in series between the power supply and the Controller Module.
See Figure 10.
8 Wire the Controller Module as described in Table 2.
9 Connect the Antenna cable to the Controller Module.
10 If you have not already done so, record the location and serial number of the ACR
for later inclusion on the floor plan.

Tuning the ACR
The ACR will work in most installations without tuning. However, tuning features have
been provided to accommodate the widest possible range of installations.
When do you need to tune the ACR?
You need to tune the ACR when it is installed near a metallic object or structure and
the range of the LF Field does not provide a minimal operational microchip detection
zone.
The microchip detection zone is dependent on the size of the LF Field. The largest
possible LF Field extends approximately 3 in. to 4 in. from the Antenna surface
depending on site conditions. If the detection zone is less than this, it is possible that
tuning the Antenna may increase the LF Field size. However, Antennas are shipped
tuned. So, if your LF Field size is adequate, there may not be any advantage to tuning.

Mounting the Antenna Inside a Wall
When the Antenna must be located inside a wall, consider the following:
The detection zone will be smaller due to the wall thickness. You may not have a
large enough detection zone on both sides of the wall. For example, Figure 9 shows
an Antenna mounted inside a 4 in. (10.16 cm) wall. In the figure, only about 1 in.
(2.54 cm) of the LF field extends into the corridor on the right side of the wall.
The wall material must not contain metal that would block the LF Field.
The Antenna must be mounted vertically to ensure an even detection zone.
You will need to construct a mounting surface inside the wall. Do not suspend the
Antenna by the cable.
