NOTE:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a commercial or residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

MicroBadge 4053 Reader
Description
The MicroBadge 4053 RFID reader is a self-contained low frequency reader for
powering and interrogating passive RFID transponders. The reader is configured to
interface with other electronic devices via an RS-232 or RS-485 connection.
The 4053 reader emits a low frequency magnetic field, which will provide enough
energy to power a transponder within the read range of the transponder. The
transponder will send a unique identification, which the reader detects. If the
identification code is valid and the internal error detection determines that there are
no errors in the data received, an audible tone is emitted, the red LED on the front of
the reader turns to green, and the code is sent to the RS232 or RS484 port of the
reader.

Section
Installation Instructions
The reader should be mounted near the location that is desired to be monitored.
Before final installation of the reader, test the system with tags at range and
orientation typical of system operation. Typically, the read range for a credit card size
transponder is approximately 8 inches, and an 18mm button transponder has a read
range of 5 inches. Caution should be taken that the reader is not mounted within 12
inches of metallic objects, because of possible performance degradation of the system.
Once a suitable location is determined, position the reader to allow the transponder to
be presented nearly parallel to the face of the reader. This allows for the greatest read
range for the entire system.
After the reader is mounted, the 12 VDC (nominally) power transformer should be
plugged into a 110 volt, 50 – 60 Hz socket, and the power plug from transformer
should be plugged into the reader power jack. The LED indicator on the front of the
reader should be glowing with a RED color.
Next, plug an RS232 cable with a nine–pin connector into the RS232 port of the
reader, and connect the other end of the cable into the serial port of a computer.
To test the functionality of the reader, start up a terminal program in the computer.
(PROCOM or Windows terminal program will work fine.) Set the communications
parameters to 19,2000 baud, no parity, eight data bits, and one stop bit. Make certain
that the port selected in the terminal port corresponds to the port that the RS232
cable is connected.
Next, present a transponder to the reader at approximately 4 inches and parallel to the
face of the reader. An audible “beep” should be heard, and the LED should
alternately flash RED and GREEN. Moreover, you should see a string of 18 digits
displayed on the computer monitor. These digits correspond to the identification
code stored in the transponder.
If an audible “beep” is head, but the computer does not display the 18 digits on the
monitor, verify that the proper port is selected, and that the proper communications
parameters are set.

If an audible “beep” is not heard, verify that the LED is glowing RED, which
indicates that power is being supplied to the reader. Try another transponder, and
bring it closer to the reader antenna. If this fails to produce a sound, disconnect the
unit from the computer and from power and call the factory.
