OVERVIEW

The DigiPageJr features extensive flexibility in the range of input sources that it can
accommodate. In addition, the zone outputs may be used to feed power (booster)
amplifiers, mixers, mixer amplifiers etc. It is therefore important to think about the interfacing
of the DigiPageJr with the other equipment if optimum performance and system stability is to
be achieved. Use the Back Panel and Specifications sections of this manual to assist with
system design.

NOTE: If installing and terminating CAT5 cable is new to you, please take note of the

various points that follow. As the CAT5 cabling for the DigiPageJr carries voltage,
damage could occur if your pin-pin connections are not made correctly.

CABLE INSTALLATION FOR PAGING STATIONS

Four RJ45 ports (labelled ) are provided for connection to the DigiPageJr Zone

CAT 5 RUN 1-4

Paging Stations. The four ports allow for easy cable infrastructure, as CAT5 runs can be of
differing lengths depending on the installation and the number of paging stations
connected.

In planning the installation, the following rules apply:

Up to 4 Paging Stations may be connected to each of the four CAT5 runs.

!

Connections along the runs must be in a daisy-chain configuration. It is acceptable to

!

create a short branch (eg, from a wall outlet to a paging station). The maximum
length of the branch is 10m.
The following table indicates the maximum distance allowable for a CAT5 run on a

!

single port.
For greater distances or more paging stations, see page 14.

!

The last unit on a run must be terminated. This is done by moving a jumper on the

!

paging station or remote unit. See ‘Paging Station’ on page 18 or ‘Remote Control
Panel’ on page 21.

Australian Monitor

INSTALLATION SERIES

INSTALLATION OF A PRIORITY PAGING STATION

The following rules apply for connecting a paging station as a priority paging station to over
ride all other paging stations:

The paging station must be enabled as a priority paging station (see Paging Station

!

section on page 20).
The paging station that is used as a priority station must be connected to CAT5 RUN 1.

!

The only paging station that can be connected to CAT5 RUN 1 is the priority paging

!

station. No other paging stations may share that CAT5 RUN.

NOTE: These are Ethernet connections.NOT

CAT5 CABLE

CAT5 cable is the blue cable commonly used for data installations (other colours do exist). It
consists of four twisted pairs of wires: this is why it is often referred to as UTP (Unshielded Twisted
Pair). The most readily available cable uses solid conductors, like telephone wire. Cable with
stranded conductors is available, and is more flexible.

CAT5 TERMINATION

Pre-wired CAT5 cable comes in two configuration standards, 568A and 568B. It is advisable to
carry a good pre-wired cable for fault-finding. Both configurations will work with the
DigiPageJr provided both ends have the same configuration. Be careful not to use a
crossover cable which has one configuration at one end and the other configuration at the
other end.

Ensure that the RJ45 connectors are suited to the cable used (solid or stranded) and that the
correct crimp tool is used.

When wiring connectors, 568A standard wiring is recommended (see diagram).

POWER REQUIREMENTS

The DigiPageJr can operate from the plug pack supplied and/or a separate 24V DC power
supply.

A NOTE ABOUT GROUNDING:
It may be necessary in some circumstances to ground the DigiPageJr to eliminate
noise in the system. This can be done using the negative terminal of the 24VDC IN
euro connector or by making sure that the chassis is electrically connected to the
equipment rack (which should be grounded).

EXTENDING CAT5 CABLE RUN DISTANCES & ADDING MORE PAGING STATIONS

The maximum distances quoted in the Table #1 are due to DC current limitations, not data
transmission limitions. If distances greater than these are required, the paging stations can
be locally powered. This will extend the maximum distances to 1000m per CAT5 RUN.
Alternatively, if more than 4 paging stations are required on a single run, local powering can
be used. This will increase the maximum number of paging stations on a single CAT5 RUN.
Use a 12VDC supply connected as

regulated

pin1 (white/green in CAT5)- GROUND

pin2 (green in CAT5) - +12V
Disconnect incoming +V, but not ground. The 12V supply should be rated at 150mA per
microphone being powered. For further information email [e-mail].

TONE GENERATOR INPUTS

Tones may be triggered by closing a switch or relay contact between the selected tone
trigger input and common. These trigger inputs are 5V TTL and may alternatively be triggered
by pulling the desired input low referenced to the COMMON.

NOTE: The maximum voltage on these inputs must not exceed 5.5V

PRE-ANNOUNCE CHIME

The only internal setup that is available in the DigiPageJr is for the configuration of the chime
tone that sounds in each zone. The unit comes shipped with the chime enabled in all zones.
A link can be found on the main board just behind the zone control boards (see diagram).
To disable the chime to a particular zone, remove the link. To re-enable the chime, replace
the link.

NOTE: Remember to wait for the chime to finish before speaking. Note that when

the chime is disable it will still activate but will not be heard so you must still
wait approximately 1 sec before speaking after press the page button.

5. SET UP

The inputs of the DigiPageJr can accommodate a wide range of sources including active
paging stations, dynamic microphones, DVD and CD players, tuners and cassette players.
The zone outputs may be used to drive power (booster) amplifiers,mixers, or mixer amplifiers.

Each installation will require setting the appropriate relative mix of levels between paging
and program sources for each zone and balancing between the zones.

Because of the variation in levels between the possible sources, DigiPageJr offers a number
of gain stage adjustment so you can set the correct levels for your application.

Also consider what the outputs are driving.

Setting up correct gain structure through the whole system is important to achieve optimal
results.

The following step by step procedure has been devised to assist during the setup process.
When the DigiPageJr was shipped to you from the factory it was set up in a particular way. In
the following procedure it is essential that you are starting from these initial settings.

Program Input Gain Controls - half (12 o’clock)

Master Volume - off

!

Mic level - half (3 o’clock)

!

Prog level - half (3 o’clock)

!

Step by step setup

Confirm the initial settings of DigiPageJr.

Choose a zone that is conveniently located near to the DigiPageJr or further away if you feel
you need the exercise.

This will be the referred to as “TEST ZONE”.
Ensure that all amplifiers connected to the DigiPageJr are set to provide required sound levels
with a line level input signal.

Choose a consistent program source, eg CD or tuner.
This will be the referred to as “TEST PROG”.

1. Select TEST PROG in the TEST ZONE [front PROG 1-4].
Set the MASTER volume in the TEST ZONE to half way.

2. Adjust the rear PROG GAIN for the TEST PROG input to achieve the required sound level
in the TEST ZONE.

3. Select PROG TEST in all other zones.

4. Bring up the MASTER volume in all other zones and check for required sound levels.

5. Make a test page to the TEST ZONE and check the level relative to the program level.

6. Adjust the page level as desired [front panel PAGE].

b. Set Eq
c. Set final master level

NOTE: A full discussion of setting up a complex system with correct gain structure is

beyond the scope of this manual. The procedure above assumes that the
installer has correctly set up external equipment connected to DigipageJr
prior to initiating the set up procedure.

6. LINKING TWO DIGIPAGEJr SYSTEMS

NOTE: There are two series of DigiPage product available, the DigiPage and the

DigiPageJr. Use only DigiPageJr series paging stations with DigiPageJr and
only DigiPage series paging stations with DigiPage.

DigiPageJr is fully expandable to form a 16 zone paging system by the simple linking of two
units. One DigiPageJr is then designated the master unit, driving zones 1-8, with the other
slave unit driving zones 9-16. The following settings and connections are required to form a
linked DigiPageJr system.

The DigiPageJrM16 paging station must be used to access all zones. The DigiPageJrM8 can
also be used but will only access zones 1 to 8

PROG LINKS

Program sources can be sent to the slave DigiPageJr by connecting the PROG LINKS OUTPUT
on the Master unit to the PROG LINKS INPUT on the Slave unit. This simplifies connection of
sources as all 4 sources can be sent from the master to the slave via 1 CAT5 cable avoiding
the need for Y-cables
The PROG TRIM on the slave unit operates independently of the master unit. The PROG TRIM
on the slave unit should be set to the same position as on the master.
Use a pre-wired CAT5 patch lead. The maximum cable length for the program source link
cable is 0.5m. However this cable should be kept as short as possible because it is carrying
audio signal.

NOTE: If PROG LINKS is not used, it is possible to use completely different program

sources in zones 1-8 to zones 9-16.

NOTE: Maximum prog link cable length is 0.5m

PRIORITY PAGING STATION

If a priority paging station is being used in a linked 16 zone system it must be connected to
CAT5 RUN 1 of the unit.master

Introduction

The Australian Monitor Installation Series DigiPageJrM8 and DigiPageJrM16 Paging Stations
are 8 and 16 zone paging stations complete with a slimline gooseneck paging microphone.
The Paging stations are designed to be used with the DigiPageJr Zone Paging & Source
Selection System and will allow paging into any individual zone, any combination of zones or
All Call to all zones. LED indicators provide the user with visual feedback of the zones being
paged or if the sytem is busy. Label space is provided on the Paging Station, which also
provides a microphone gain control. Connection to the DigiPageJr is via low cost CAT 5
cable and as with all Australian Monitor installation products, the Paging Station provides an
elegant solution at a contractor friendly price.

is not possible while the system is busy, however zone
selections can still be made.

18

Installation and Setup

NOTE: There are two series of DigiPage product available, the DigiPage and the

DigiPageJr. Use only DigiPageJr series paging stations with DigiPageJr and
only DigiPage series paging stations with DigiPage.

The CAT5 cable connects to the RJ45 socket on the rear panel of the paging station. This
socket is a NEUTRIK connector designed to be used with the XLR style housing (model

TM

NE8MC) to improve reliability. Normal RJ45 connectors can also be used.

Plugging and unplugging the cable while the system is powered up may result in the system
locking up and is not recommended. If this should happen, reset the DigiPageJr by switching
off, then on.

6 GAIN

To accommodate different speech levels, there is a gain control on the base of the
DigiPageJrM. This ships set to minimum and may be adjusted to suit. Increasing this
control too far may cause the paging station to distort if loud or close speech levels are
encountered. Caution should be used if trying to achieve high gain levels for distant or
lectern speech styles as feedback may occur.

7 TERMINATING

In an RS485 network (of which the DigiPageJr is part of) it is important to terminate the last
device in each CAT5 RUN. A jumper is provided for the data/voice transmission to be
terminated if that Paging Station is at the end of a CAT5 RUN (see diagram). Shipped as
unterminated.

8 PRIORITY

If a Paging station is being used as a priority over all other Paging Stations then the
following rules apply
The Priority Paging Station must be connected to CAT5 RUN 1
No other Paging station may be connected to CAT5 RUN 1
The Priority Paging Station must be set as priority by moving the jumper (see diagram).
Shipped no priority set.

NOTE: When making changes be sure to power off and disconnect .
