2. To test the reader’s RS-232 output:

• Interface the reader’s 3 RS-232 data lines to the system’s controller, or

• Interface the reader’s 3 RS-232 data lines to a different commercial system that works normally with other readers

and cards, or with other RS-232 output devices, or

• Clip the test unit from AWID’s LR-2000KIT Test & Set-up Kit to the LR-2000 reader, or

• Interface the reader’s 3 RS-232 data lines to the serial port of a PC, and run the Windows HyperTerminal program *, or

• Connect the leads for a single-trace oscilloscope suitable for AWID’s data output (9,600 bits per second)

between the reader’s Transmit Data and Data Common wires.

* In Microsoft Windows, the path is: Start Æ Programs Æ Accessories Æ Communications Æ HyperTerminal Æ

Hypertrm.exe. Configuration is 9,600 bits per second, 1 start bit, 8 data bits, 1 stop bit, no parity,

ASCII emulation, flow control = any. To open the port and start HyperTerminal, click on the Call tab at the top

of the window, and select the option “Start Call”.

7.4 TESTING AN APPLICATION SYSTEM

When the LR-2000 reader is interfaced to the reader input port of the application system, the format of displayed data depends

upon the programming of the system. In a typical access control or automated vehicle identification system, the program

allows selection of a code format that replicates the Wiegand-style encoding that AWID has programmed into the credentials.

Therefore the system’s monitor may display the code data in the same data fields, and the same number system (decimal), that AWID

uses for its encoding. Testing may be as simple as reading the decimal values of the credential’s data fields on the monitor.

If the system’s monitor indicates that data are received from the reader but not recognized by the host (“Code format error”,

“Facility code error”, “Parity error”, etc.) –

• Check the host’s programming.

• Check the reader’s output.

• Check the wiring between the reader and the controller.

• Check the credential’s code on a different reader or on a different system.

If the system’s monitor indicates no data input from the reader –

• Test the LR-2000 reader and the credential by interfacing to a different controller that is known to work normally.

• Test the system by connecting the LR-2000 reader directly to the controller’s reader port, bypassing the cable and junctions.

• Test the system’s input using a different reader and compatible card or tag.

8 INSTRUCTIONS FOR LR-2000HiLoMA READER SET

AWID’s LR-2000HiLoMA is a set of two units that work together at a reader location. One unit is a Master Reader that controls

the alternation of RF transmission between the two units. The second unit is a Remote Antenna, in an identical housing. The two units

are interconnected by a coaxial cable. Instructions for installing the LR-2000HiLoMA reader set can be downloaded from the

public documents in AWID’s Web site, www.awid.com

• Position: The master reader and the remote antenna may be in either position at the site. The deciding factor may be the position

of the master reader that results in the easiest or shortest cabling.

• Separation: AWID supplies a 6 foot long coaxial cable to connect the remote antenna to the master reader. When installed

on brackets, the practical maximum separation between the master reader and the remote antenna is about 4 feet. Do not attempt

to substitute a longer cable because of electrical loss in the cable.

• Accessories: All accessories for the LR-2000 reader apply also to the LR-2000HiLoMA reader set. Use the same LR-2000KIT.

• Reference Documents: o LR-2000HiLoMA Installation Sheet. o Technical Reference issues for description, applications, etc.
