Linear WOR: Wiegand Output Receiver

The Model WOR Wiegand Output Receiver is designed for use as an access control interface for Linear’s block coded digital transmitters. The unit receives signals from transmitters, adds a facility code to the data, and sends the information to the Wiegand input of the access control panel via a 5-wire connection.

Several transmitter and receiver options can be set using the unit’s dipswitches. Three different Wiegand output formats (26, 30, & 31-bit) are supported. Three receiver options (lockout, hold, & button offset) can be set. Transmitter buttons on multi-button units can be selectively disabled. The facility code is set using 16 dipswitches.

Three antenna types can be used with this receiver. The local whip antenna (supplied) screws directly on to the receiver. The directional (EXA-2000) and omni-directional (EXA-1000) remote antennas attach to the receiver’s antenna input via RG-59 cable and a type F connector.

An on-board RADIO RANGE knob allows adjustment of the receiver’s gain. It can be set to limit the maximum radio range that the receiver can achieve. Two indicators display the receivers performance and operation. The red RADIO indicator lights when the receiver detects a radio signal. The two color red/green STATUS indicator lights green when the receiver is sending Wiegand data and during the 1-second post receiver lockout timer (if receiver lockout is enabled). The indicator turns red when the receiver’s HOLD input (connected to the access control panel) is active. Receiver test points are provided for listening to the incoming signals with an audio amplifier.

The receiver is housed in a weather-resistant enclosure and can be mounted indoors or outdoors. Gaskets and a weather-tight wiring strain relief seal the unit from the elements.

OUTPUTS

Data:

Terminal block output "Data 0" and "Data 1" standard Wiegand electrical and protocol interface

LEDs:

Red RF activity LED indicates RF activity at 318 MHz; red/green decode LED is green during Wiegand data transmissions and receiver hold timing window (if enabled) after any output transmission; otherwise it is off unless hold enable is selected, in which case LED will remain red until hold is removed by host system

CONTROLS

Pushbutton:

Momentary switch labeled "Program" used to configure microprocessor after system option selection and configuration

DIP SWITCHES

Receiver Facility Code:

Four positions to select 1 of 16 possible MegaCode facility codes; if code 0 is selected, the receiver will validate any received facility code; any other selection requires the transmitters' facility code to match the receiver facility code selection for validation

Output Facility Code:

16 positions to select one of 65,536 possible facility codes; a selected output format may not use all 16 bits

Output Format:

3 positions for selecting either 26, 30, or 31bit Wiegand output format

Button Disable:

5 positions, each corresponding to 1 of 5 possible MegaCode transmitter buttons - left or top left, right or top right, bottom left, bottom right, top

Receiver Lockout Disable:

1 position; if set to ON, the 1 second receiver lockout is not performed

Button Offset:

1 position; if set to ON, the transmitter ID number is offset with a number based on which button is pressed:

Button	Offset
Left	0
Right	16384
Bottom Left	32768
Bottom Right	49152

Wiring:

up to 300 feet with 24 AWG, 500 feet with 20 AWG; up to 1,000 feet, CAT-5

Enclosure:

Weather-resistant, anodized aluminum enclosure with removable end caps to provide wiring and programming access; end caps secured with screws

Operating Temperature:

-22° to +155° F (-30° to +70° C)

Electrical:

Robust RFI and ESD protection for all inputs and outputs, including antenna input; protection to prevent output errors during brownouts
