The unit is supplied with either 4 or 8 inputs, which can be hardware configured to accept either dry contact (no voltage) or voltage (5-18V dc) triggers.
DigiLink US, ECO DC Version Some major points to consider when installing equipment: 1 Never install antennas near or adjacent to telephone, public address or data communication lines or overhead power cables. 2 Avoid, where ever possible, running antenna coax alongside other cables. 3 Avoid mounting the transmitter in suspended ceiling voids, or in the immediate vicinity of telephone exchanges or computer equipment. 4 Always use 50 ohm coaxial cable between the antenna and the transmitter.
DigiLink US, ECO DC Version Installation The following procedure must be adhered to when installing the DigiLink paging system. Ensure you have taken into consideration all of the above information before selecting the location for your transmitter. If in doubt consult your dealer. 1 Remove the cover from the DigiLink transmitter unit by unscrewing the two Pozi head screws located at the top and bottom of the unit (see Diagram 1). 2 Carefully lift off the cover and set aside.

DigiLink US DC Version Section 2: System Operation Confirmation of power connection is by way of the red LED on the front fascia. This will remain off until a zone is triggered. It will then blink continuously, except during transmission repeat periods or when the power source falls below 10.5V dc, when it will remain off. Confirmation of transmit is by way of the momentary green LED on the front fascia. This will light for approximately 1 second each time a transmission occurs.
