How to set up equipment
:


Stands
:

Step 1:

Adjust the tripod/pulley system stands at a distance of thirty feet apart from each

other.




Step
2
:
Check to see that the string

in between the stands has a small amount of slack so



that it is not pulling too tightly for the motor to turn.

Step
3
:
Ensure tha
t all of the equipment is secure

to
or on
the stands.



Cables
:

Step 1:

Connect the ser
ial cable with the mini gender chan
ger end to the direct

connection port on the PCB board. Connect the other end of cable to the RS
-
232

port on the ALR
-
9780 reader.

Step 2:

Connect serial cable into Direct RC2 port on PCB board to the serial port on your

computer.


Step 3:

Connect 12V power supply to power leads on board. Red lead goes to positive,

Black lead goes to ground.



Tag
:

Step 1:
Secure the tag onto the lower level of the string on the side of the pulley system
closest to the motor.




6






Reader
:

Step 1:
Ensure that the power supply for the reader is connected and working properly


either with battery supply or 12V ac adapter.

Step 2:
Connect the reader antenna cable onto ANTO port on the reader.

How To Run HyperTerminal


Fo
r
the use of range testing,

HyperTerminal is a program that will read data from
the PCB board serial ports. It is
also
used to send the reader commands and receive
information back that can then be displayed.

There are two COM setting in HyperTerminal.

COM1 will show the number of
signals that the reader is receiving back and COM2 will show the commands that are
being sent to the reader


To run HyperTerminal for the RFID Range

Tester
:


Step 1
:

Open HyperTerminal program

Step 2:
Enter any name that you

choose when prompted

Step 3:

Choose COM1
or COM2 depending on the information you wish to receive. For


test results, choose COM1.




Step 4:
Change the baud rate/bits per second to 19200




8

Step 5:
If the connection does not occur automatically, c
lick on the
Connect
icon on the


screen. The information should then appear in the box.

Features of Motor Control PCB Board
:



Power Switches
are used to turn on and off the motor power and power to the
entire circuit.




Attenuation Switch

is to cho
ose of you want to take readings by changing
distance or if you want to take readings with no changing distances but altered
attenuations.



Variable Power supply capabilities

are also a feature of this board. It is able to
run off of a power supply rangi
ng from a 5
-
36V input.



LCD Display

is used to see the tag ID that is being read, the number of responses
that the antenna has received back from the tag and the number of times that the tag has
moved away from the original position.

There is also a contr
ast adjuster
for easy viewing.




15 LEDs
each to help monitor that the elements in the circuit are working
properly. The let you know when different elements are on and when. There are motor
channel indicators, power indicators, direction indicators, an
d reader signal indicators
.

Each

on is labeled on the board and each section is separated with a different color. This
is useful for seeing if an element has lost power or isn’t making a connection when
troubleshooting.




4 Serial Ports
are supplied for

in circuit programming, or for the use of
HyperTerminal and reader data.




In circuit programming

is possible with this board but not a required feature for
testing.

Basic Operation
:


Step 1:

Set
-
up equipment as directed in equipment set
-
up

Step 2:

Open and setup HyperTerminal as directed.

Step 3:

Switch

power, motor power, an
d
attenuation switched into the “up” position for

distance test or leave attenuation switch down for attenuation test.

Step 4:

Read the results from hyper terminal or the display for testing needs.

Step 5:

Wait for tag to return to its original position a
nd switch tag if desired.

Step 6:

Turn off and on master power
switch
for new test.





Troubleshooting
:


Motor Shutters:

Give more slack in the string.


Can’t read LCD display:

Try adjusting contrast.


Board loses power:

The voltage regulator has a the
rmal shutdown mode so try turning



off master power and giving 5 minutes to cool down, then restart




test.


If test results are not showing properly:

Try turning of master power and turn back on to restart test.
