CDVI WIRELESS S.P.A. DTRR1 ユーザーズマニュアル

The DigiTag-LR Receiver is designed to be mounted in proximity to the door or 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 DigiTag-LR receiver has an internal 
antenna that detects the DigiTag-LR 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 tags through metal objects 
and will be impeded by large dense obstacles between it and the tag, 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, and 
we recommend the use of screened cable such as Beldon 9535 or an equivalent.

The DigiTag-LR Receiver can be connected 
directly to the CDV Group DG-502M access control 
unit or to any access control system controller that 
supports the Wiegand 26 Bit or Clock & Data ISO 
format industry standard interfaces.  A maximum 
cable distance when using screened cable is 
around 30 metres to a CDV Group DG502M access 
control unit or 75M when using the industry 
standard Wiegand or Clock & Data interface option.
