LED Indicators
The DigiTag-LR receiver has 2 LED lights. The red is always on and indicates that power is applied to the device
and it is ready to read and decode transmitters. The high efficiency bright green flashes briefly when a
transmitter's transmission is detected in the field. The green LED remains on if the connected access control
system validates the transmitted code. Whilst the green LED is illuminated the receiver will not read and decode
any more transmitter transmissions.
Range Adjustment
The maximum range of the receiver is dependant on environmental conditions, transmitter orientation and
transmitter battery life but should be approximately 15M in high gain mode and the attenuator control set to
position '0'. A small 2 pin jumper is present and if disconnected selects low gain mode. Additional the attenuator
control can be rotated to give further range reductions. The lowest range setting would therefore be with the
attenuator set to '9' and the low gain mode selected on the 2 pin jumper.
DIP Switch Settings
The DigiTag-LR receiver has options to select output interface type and various logical settings.

Switch 1
: Selects the industry standard interface device type. It is recommended that this switch remains off
and utilise the Wiegand 26 Bit standard when connecting to third party access controls or to the CDV Group
brands Link.net & Centaur.
Switch 2
: When off allows both automatic and manual pressed transmissions to be read and decoded but when
set to on, will only read and decode manual user pressed transmissions.
Switch 3
: When set to off enables the tag to be read and decoded repeatedly whilst in the receivers detection
field.
When on, the tag is read and decoded only twice before ignoring it until it is removed from the receiver's detection
field for at least 10 seconds.
Switch 4
: When on, connects two 4K7 pull-up resistors to the outputs D0 and D1 to 5Volts. This switch should
be normally on but in some cases third party access control units require open-collector style outputs and in this
case switch 4 should be off.
