PREFACE
Important Installation Information
It is the purchasers’ responsibility to determine the suitability of this equipment and its derivatives for
any given application, Scope cannot give specific advice in this manual, as each use will require
independent evaluation.
Scope has, wherever possible, employed extra safeguards to monitor the system’s performance.
Certain system installations, operational requirements or budgets may, however, limit the
effectiveness of these safeguards. Again, the suitability of the system for any given application must
therefore be decided by the installer and their customer, relative to the application and risk.

System Overview
The Scope Digilink MK3 DL10AC and DL5AC are mains powered, programmable radio paging
systems which can be used to transmit data to fixed base stations and/or portable receivers. The unit
is supplied with either 5 or 10 inputs, which can be hardware configured to accept either dry contact
(no voltage) or voltage (5-18V dc) triggers. Each input is pre-programmed as either N/O (Normally
Open), N/C (Normally Closed) or C/S (Change of State). Triggering any of the inputs (zones) will
result in pre-programmed data (including up to 80 characters of text message) being transmitted to
the selected receiver or group of receivers.
The unit can be programmed to repeat transmit (1-5 repeat transmissions or until reset) if required. In
addition, the trigger filter time can be defined between 100 milliseconds and 25 seconds (period for
which the zone must remain in the active state before triggering). One input (IN9) can be configured
as a Reset to clear any current transmission cycles. This can also be used as an “Arm/Disarm” facility
for the alarm inputs. Various other parameters can be programmed to suit specific user requirements.
The Configuration Data sheets accompanying your system will detail how all the various parameters
have been set. It is vital that you retain this information in a safe place as you will need to quote the
unit’s serial number in the unlikely event that you experience any problems. You will also need this
information to order more pagers (these must be matched to the identity of your system).
For advanced users who wish to program the unit themselves, a Programming Kit must be
purchased. This provides a Windows based application running on a PC's USB port, allowing all
functions to be programmed and stored in the system’s secure non-volatile memory. Full details can
be found in the PT10 Pro Configuration Utility provided on CD with the Programming Kit.
Section 1: Installation
The information contained in this Section is intended for use by authorised system
installation engineers only. Other personnel should not undertake installation of this
equipment under any circumstances.
Siting of the hardware
Before locating the hardware in any given location, it is important to take into account the range of
operation that you require. The standard transmitter can quite easily provide ranges of up to a mile
or more, covering a considerable area with just a quarter wave antenna connected directly to the unit.
For coverage of very large sites, or where exceptionally difficult operating conditions exist, it may be
advantageous to install an external antenna. Installing the transmitter on the second or third floor of
a building will more often than not boost overall range. However, horizontal range is not always
required as much as propagation through a multi-storey building. Here it may be more useful to use
a small external antenna mounted outside the building at half the building height. Sometimes range
is required more in one direction than in the other: moving the aerial to one side of the building can
provide a bias in the required direction, which may overcome the range difficulties. (See section:
Other Antennas).
Important: coaxial feeds which are longer than 5 metres must employ low loss 50 ohm coax. We
normally do not recommend feeds of more than 15 metres for standard applications. However, we
suggest you contact our technical department where other considerations may prove this to be
impractical.
A further consideration that must be taken into account is the length and location of the dry contact
cables. To avoid interference and possible false triggering, cable runs should be kept to a minimum
(ideally less than 10 metres) and should be isolated from other cabling (e.g. mains, telecoms. PC
networks, etc).

Caution! RF exposure requirements: this product should be installed so as to ensure a separation
distance of greater than 20 cm between the antenna and all persons during normal use.
Some major points to consider when installing equipment:
Never install antennas near or adjacent to telephone, public address or data
communication lines or overhead power cables.
Avoid, where ever possible, running antenna coax alongside other cables.
Avoid mounting the transmitter in the immediate vicinity of telephone exchanges
or computer equipment.
Always use 50 ohm coaxial cable between the antenna and the transmitter. If
cable runs exceed 5 metres, always use low loss 50 ohm cable such as RG213 or
UR67.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM and
therefore totally unsuitable for any transmitter installation manufactured by Scope.
Also remember that the performance of the system will be affected by the type of
material the unit is mounted on and its surroundings.
The following is a list of materials that this transmitter will be adversely affected by if
mounted on or if mounted in close proximity to:
a)
b)
c)
d)
Foil back plasterboard
Metal mesh or wire reinforced glass
Metal sheeting, large mirrors or suspended ceilings
Lift shafts
All of the above can reflect radio waves and thereby reduce the capability of the
transmitter to perform its desired functions.
The circuit boards within this equipment may be harmed by Electrostatic Discharge
(ESD). Installers should ensure that both themselves and the system’s
chassis are grounded before beginning any installation, and should ensure
that adequate anti-static procedures are adhered to at all times.
Warning! Never transmit without an aerial attached to the transmitter
Warning! Carefully check the Installation section in this manual covering terminal
connections prior to installation. Damage caused by incorrect connection is the
responsibility of the installer!

Installation
The following procedure must be adhered to when installing the Digilink system. Ensure you have
taken into consideration all of the above information before selecting the location for your transmitter.
If in doubt please feel free to telephone the technical helpline on 01803 860710.
Remove the cover from the Digilink transmitter unit by slackening the four Pozi head screws
located at the top and bottom of the unit (see Diagram 1).
Carefully lift off the cover and set aside.
The transmitter should be fixed to an even wall surface using suitable screws fitted through
the three holes provided in the chassis plate. Hold the chassis up to the chosen location and
with the aid of a pencil mark the position of the mounting holes.
Warning: Do not use the chassis plate as a template for drilling the holes into the wall. Hammer
drills vibrating through the chassis may irreparably damage the quartz crystals on the printed circuit
boards.
Place the Digilink transmitter over the mounting holes and secure the unit with suitable
screws. Check that the chassis plate does not bend and that the screws do not snag or pinch
any of the internal cables.
Connect the antenna to the unit via the BNC connector located at the top of the housing. If
the antenna is an external antenna, or an antenna which is separate from the transmitter unit
itself, ensure that the previous criteria covered under the section headed Siting of the
Hardware, have been strictly adhered to (also see section headed Other Antennas).
Connect the input cables to the zone terminals. Unless the unit has been specifically
configured for voltage input, these should be simple “dry” (no voltage) contacts only (i.e.
isolated switch or relay contacts).
If configured for voltage input (5-18V dc), the jumper link beside the relevant terminal must
be positioned nearest the “V” symbol marked on the circuit board (see Diagram 2).
If in doubt, check with Scope before proceeding; incorrect connection may cause
permanent damage.
If the unit is supplied with a sealed lead acid battery, insert the supplied fuse (2A AS type)
into the holder and screw together the two halves. Plug the lead into the BATT connector
(CN17) on the PT10 board, as shown on Diagram 2.The battery will now be in circuit and the
unit will power up. NOTE: only use fuse rating & type supplied.
A relay output is provided to indicate loss of external (mains) power. If required, connection
can be made to J14 terminal block (see Diagram 2), using either N/O or N/C terminal and the
Common terminal. The relay is energised when external supply is present and drops out
when power is lost. Relay max contact rating is 1A @ 60V dc and must not be exceeded.
Replace the cover and re-tighten the four retaining screws.
10
Finally, after checking all connections, connect the mains cable supplied to a suitable
isolated, fused spur or switched wall outlet. With mains power correctly applied, the red LED
on the base of the unit will light and a "Digilink Reset" message will be sent to the receiver(s)
to indicate successful initialisation.
11
The system is now active and will transmit the pre-programmed data/message for each of
the zones when triggered. Repeat transmissions and other programmed parameters (e.g.
battery low message) will be identified on the Configuration Data sheet(s) supplied with the
system.

Section 2: System Operation
Confirmation of power connection is by way of the red PWR indicator on the base of the chassis.
Confirmation of transmit is by way of the momentary green TX indicator on the base of the chassis.
When any zone is changed to it’s active state, the pre-programmed data/message for that zone will
be transmitted to the receiver(s). Repeat transmissions can be programmed for added security, these
will be detailed on the Configuration Data sheets provided with your system.
Where the system has been configured for voltage input:
volts present = an open input, no volts = a closed input.
The siren output is an “open collector” type switching to ground. It may be used to switch up to 24V
dc @ 1A max. Note that if it is used to switch a relay, a suitable diode must be connected across the
relay coil (stripe towards positive side of coil).
Problems and Fault Finding.
Check that the input cables are connected to the active zones. For a 5 zone unit,
these are the lowermost terminal blocks on the main PCB (see Diagram 2).
Check the Configuration Data sheet supplied with the system to confirm the active
(trigger) state of each input i.e. Normally Open, Normally Closed or Change of
State.
If your system has been configured for Dry Contact operation, ensure that no
voltage is present on the input cables. Also check that cable runs are not excessive
(preferably less than 10 metres) and are not in close proximity to other mains or
telecoms cabling.
Check that the receivers are at least 3 metres from the transmitter and aerial.
Under certain conditions it is possible to flood receivers and corrupt the data
received.
Check that any portable receivers used with the system have the battery installed
with the correct polarity and are correctly powered up.
Check that the red power indicator on the base of the chassis is lit. If not, isolate the
power and check the mains plug fuse.
Check that the green TX indicator lights for the duration of the transmission. If not,
go back to the cabling and re-check the terminal connections.
Check that the aerial is correctly installed.

Other Antennas
In addition to the standard BNC mount 1/4 wave antenna (UHF14BNC), which attaches directly to the
Connexions transmitter, the range and performance of this equipment can be improved by the
addition of more efficient antennas*. These can be installed either inside or outside the building and
are connected to the transmitter with 50 OHM coaxial cable.
The centre fed half wave di-pole, measuring approximately 12 inches from tip to tip, will provide
excellent all round local signalling. This can be mounted either inside or outside a building. Two
versions are available:
1) a light duty antenna suitable for sheltered environments/internal installation (LUHFDP).
2) a heavy duty stainless unit with optional mounting hardware for more arduous applications
(FDANT).
Pre-terminated coaxial feeder cables are available for 5, 10 or 15 metre requirements. Consult your
dealer for further details.
Note ! Only permitted for use with the above Scope approved antennas, all of which are zero Db
gain. High frequencies can equate to high power losses. Always use quality cable. RG58 is only
acceptable on cable runs of up to 5 metres. We recommend RG213, or equivalent, on greater
lengths. If in doubt consult your dealer's Technical Department.
*subject to license conditions. Specifically, mounting height and Effective Radiated Power (ERP).
