Introduction
The DigiTagLR Receiver is designed to be used with the DigiTagLR range of
active transmitters from the CDVI Group. Best performance from the
transmitter and receiver will be gained when adhering to all the relevant
instructions. The DigiTagLR receiver will read and decode the secure coded
signals from the transmitter when in the field range of the receiver and validate
this against the internal memory store of up to 30 transmitters. A single timed
relay output is available on this model to signal electronic door locking or other
automation equipment. The DigiTagLR receiver is equipped with a low / high
gain selector and a range attenuator for further transmitter detection range
reduction. The exact range is dependant on environmental conditions,
mounting proximity to metal objects and battery condition of the transmitter.
The DigiTagLR receiver contains an internal antenna that must not be
modified as it is tuned for best performance in the factory. It must always be
mounted vertically and clear of metal obstacles or mountings. Additionally an
external antenna (SEA433) can be used if you need to site the receiver
elsewhere or inside metallised structures. This is connected to the miniature
screw terminals inside the receiver housing. Hereby, CDVI Wireless Spa,
declares that the radio equipment type DTRR1434R is in compliance with
directive 2014/53/EU. The full text of the EU declaration of conformity is
available at the following internet address: www.erone.com.

Installation Procedure
The DigiTagLR Receiver is designed to be mounted in proximity to the door or gate opening at a height of 1200 – 1400 mm. It is not
recommended that the receiver is mounted over the door, but as a conventional access control reader would be.
Always mount the receiver in the upright position. The DigiTagLR receiver has an internal antenna that detects the DigiTagLR range of
active transmitters most efficiently at the front and the rear of the unit. Avoid mounting the reader on or near large metal surfaces as this
could cause poor reading performance, erratic transmitter detection or non-linear operation.
The receiver can not read active transmitters through metal objects and will be impeded by large dense obstacles between it and the
transmitter so always think line-of-site for optimal reading performance.
Cable connections are by way of screw terminals on the bottom of the circuit board.
