Linear Wiegand Output MegaCode Receiver 318MHz | LIN-WOR

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 dip switches.

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.

Features

• Easy way to equip existing installations with radio transmitter access
• Keyless entry offers user convenience, safety, and security for triggering gates, barrier arms, and doors
• The ideal way to facilitate handicapped access
• Multi-button transmitters can double as personal emergency devices for triggering security alarms
• RF input/Wiegand output receiver supports 26, 30, and 31-bit data formats
• Wide selection of MegaCode (over 1 million codes) format transmitters, with available block coding
• Field adjustable read range – from 5 to 500 feet
• Connects as easily as a card reader; transmitters are added like cards, with no software changes required
• Facility and ID codes tailored to system requirements
• A weather-resistant case for mounting outdoors

Electrical

• Robust RFI and ESD protection for all inputs and outputs, including antenna input; protection to prevent output errors during brownouts
• Power: Terminal block input “+” and “Gnd”; input voltage 5 Vdc regulated or unregulated between +6 to +24 Vdc with reverse polarity protection
• Hold: Terminal block input “Hold”; follows standard Wiegand hold line conventions; hold line can be overridden via dip switch
• Antenna: 9-1/2 in whip antenna with F-connector (supplied)
• 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 the hold is removed by the host system
• Up to 300 feet with 24 AWG, 500 feet with 20 AWG; up to 1,000 feet, CAT-5

Mechanical

• 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
• Button Offset: 1 position; if set to ON, the transmitter ID number is offset with a number based on which button is pressed
• Receiver Lockout Disable: 1 position; if set to ON, the 1-second receiver lockout is not performed
• Enclosure: Weather-resistant, anodized aluminum enclosure with removable end caps to provide wiring and programming access; end caps secured with screws
