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 or designed optional equipment to further
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.
Licence
This equipment is cleared for use within the USA under a license assigned to the exclusive importer,
PIPS Holdings Inc. License No. 950415906. Certain restrictions apply in respect of power output and
antenna installations.
Alternative frequencies are available by formal license application (Form 600) via the FCC. These
will not be subject to the same restrictions as the standard assigned license. You should obtain the
FCC Rules and Regulations, Title 47, Part 80 to End, including Parts 90 and 95, available from the
US Gov. Printing Office, GPO Bookstore, FCC Office or www.fcc.gov/oet/info/rules/

Equipment Applications
It is the user’s responsibility to determine the suitability of the Scope products for any given
application. Scope, including its subsidiaries and Distributors, cannot provide specific advice within
this manual, as each application will require independent evaluation. Common sense dictates that
certain applications may require back up systems to cover in the event of mains or equipment failure.
All applications should be thoroughly assessed by the installer in conjunction with the customer so as
to minimize risk. Scope has no control of the use and application of the frequencies issued by the
FCC. Some equipment that is individually licensed may have a greater degree of protection than
other equipment that is operated on a FCC License Assignment basis. The following information,
however, may be of benefit.
Equipment Testing.
Range tests should be carried out at least once a week on portable radio equipment, more often when
critical criteria apply. This should involve testing the unit past the limit of its required working range.
Good working practice dictates that a suitable system installation log, covering both portable and
fixed equipment must be generated, together with a record of the dates when the system has been
manually checked and/or serviced, (with the aid of suitable test equipment etc.) enabling the system
performance to be compared with the original installation data.
The frequency of the tests required will vary between applications. If portable equipment has been
dropped or is worn by a person involved in an accident, the unit should be tested again before re-use.
It must be stressed that the physical range tests are essential and that any construction work or
movement of plant or equipment could alter the signalling capability of the unit. Radio equipment, like
any other requires servicing from time to time to ensure that it is operating to its optimum
performance. It is therefore essential that equipment is inspected and tested by authorized service
centres at least once a year.

System Overview
The Scope Connexions 6 is a POCSAG data display radio paging system which can be used to
transmit both text and numeric messages direct to pocket pagers carried by individuals or entire
groups. Information is input using either or both of the two RS232 serial ports. There are also models
available which provide an additional RS232 port, a USB port, an RS485 port and an ethernet port.
Contact your Scope dealer for further details. Up to 9,999 pagers can be supported on any one
system.
Section 1: Installation
The information contained in this Section is intended for use by authorised system
installation engineers only. Unqualified personnel should not undertake installation of this
equipment under any circumstances whatsoever.
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 to obtain from your system. The standard transmitter can quite easily
provide ranges of up to a mile or more and will provide excellent propagation on most sites, covering
a considerable area with just a 1/4 wave antenna (BNC terminated) connected directly to the unit.
For coverage 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 greater 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 dept where other considerations may prove this to be impractical.
A further consideration is the distance between the transmitter and the source of the data. If the unit
is to deploy a standard RS232 serial interface, reliable reception of the data should not be attempted
in excess of 15 metres of cable. These cables should be screened/shielded and must be kept clear
of sources of induced magnetic or electrical noise. In the event that distances of over 15 metres are
required, additional drivers or amplifiers must be installed at both ends of the data link.
Note ! the Connexions transmitter is only permitted for use with the Scope antennas listed below, all
of which are zero Db gain. Use of other antennas may invalidate any or all approvals pertaining to
this equipment.
Model No. Description Gain
UHF14BNC 1/4 wave BNC mount Antenna 0 dB
LUHFDP Lightweight 1/2 wave Dipole Antenna 0 dB
FDANT Heavy Duty 1/2 Wave Dipole Antenna 0 dB
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:
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 the immediate vicinity of telephone
exchanges or computer equipment.
4 Always use proprietary 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, UR67 or equivalent.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75
OHM and therefore totally unsuitable for any transmitter installation
manufactured by Scope.
5 Also remember that the performance of the system will be effected 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) Foil back plasterboard
b) Metal mesh or wire reinforced glass
c) Metal sheeting, large mirrors or suspended ceilings
d) Lift shafts
All of the above can reflect radio waves and thereby reduce the capability of
the transmitter to perform its desired functions.
6 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.
7 Warning! Never transmit without an aerial attached to the transmitter
8 Warning! Carefully check the Installation section in this manual covering
data pin 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 ConneXions paging system. Ensure
you have taken into consideration all of the above information before selecting the location for your
transmitter.
1 Remove the cover from the ConneXions transmitter unit by slackening the four Pozi head
screws located at the top and bottom of the unit (see Diagram 1).
ConneXions CX6 Mains, Multi Port Version USA
CX6USA Issue 1
Page 6 of 15
2 Carefully lift off the cover and set aside.
3 The transmitter should be fixed to an even wall surface using suitable screws fitted through
the 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.
4 Place the ConneXions 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.
5 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).
6 It is important to note that due to the number of interfaces brought out to the 9-way ‘D’
connectors, great care should be taken to use only the lines which are applicable to your
installation. Failure to comply with this instruction will almost certainly DESTROY the unit.
In your application the transcoder has been configured as RS232 inputs on COM1, 2 and 3.
COM1, COM2 & COM3 RS232 SERIAL PORTS (9 way D Type Plug)
PIN SIGNAL DIRECTION
1 N/C
2 RECEIVE DATA (RX) IN
3 TRANSMIT DATA (TX) OUT
4 DATA TERMINAL READY (DTR) OUT
5 GROUND (GND)
6 N/C
7 REQUEST TO SEND (RTS) OUT
8 CLEAR TO SEND (CTS) IN
9 +5V 100mA max (for Scope peripherals)
As information passes only from the host equipment to the ConneXions transcoder, you will only need
to read the DTR line which if high shows that power is applied to the Connexions unit. The RTS line
will be high when the transcoder is ready to receive data. The ConneXions RTS line should be
connected to the host CTS line to facilitate correct handshaking. Prior to connecting the data cable,
thoroughly check the system pin connections as shown above. Then connect the data cable from the
host to COM1, COM2 or COM3 on the ConneXions unit. Data from a PC can be sent using the USB
port if required.
7 If the unit is supplied with a sealed lead acid battery, the flying lead connector should be
plugged into the header marked “Battery” (CN2) on the CXIF power distribution board. The
battery will now be in circuit and the unit will power up (red power LED will light on lower
chassis plate). Note: if battery fuse (F1) requires replacement at any time, use only type 2A
Anti-Surge (AS), 1.25”.
8 Replace the cover and re-tighten the four retaining screws.
9 Finally, after checking all connections, insert the mains cable into the IEC type
connector located at the base of the unit and plug in to a suitable switched wall outlet. With
mains power applied, the red LED on the base of the unit should be lit.
10 The system is now ready to accept calls from the host terminal. When a call is transmitted,
the green LED on the base of the unit will light momentarily.

Section 2: System Operation
Confirmation of power connection is by way of the red LED on the base of the transcoder
console.
Confirmation of transmit is provided by way of the momentary green LED on the base of
the transcoder console.
Sending data in the correct format (see Technical Section, Calling Pagers) will invoke
transmitted messages to the relevant pagers.
Problems and Fault Finding.
1 Check and re-check the data cable connections. This, together with an incorrect
signalling format, result in more faults than any other problem.
2 Check that the communications baud rate of the host equipment matches that of the
Connexions COM ports. The default baud rate settings on the Connexions are:
COM1 = 1200 baud, COM2 = 9600 baud (check configuration data supplied with
your order, see label on inside of chassis).
3 Check that the pagers are at least 3 metres from the transmitter and aerial.
Under certain conditions it is possible to flood the pager receivers and corrupt the
data received.
4 Check that the pagers have the battery installed with the correct polarity and are
correctly powered up. Check the pager baud rate and frequency matches the
Connexions transmitter (see label on inside of chassis plate).
5 Check that the red power LED on the base of the transcoder is lit. If not, remove the
mains cord set and check that mains is available at the supply outlet.
6 Check that the green LED lights for the duration of the transmission. If not, go back
to the data cabling and re-check the signal format.
7 Check that the aerial is correctly installed.
IMPORTANT: Isolate mains before removing cover. Internal access and adjustments strictly
limited to authorised service personnel only.
Radio Transmission Baud Rate
This is set at the factory to suit the pagers supplied and will normally be set at either 512 or
1200 baud. Please refer to the separate configuration sheet and/or delivery note supplied
with your unit.

Optional Dry Contacts
This option must be specified at time of ordering, along with the pre-programmed messages required.
The purchaser should also order the dry contact interface box (Part Code: DC8) for ease of
connection to the contact terminals (see Diagram 2).
Warning! Voltages applied to any of these contacts will cause irreparable damage!
This unit can support up to 8 dry (volt-free) contacts on PL1, which, when shorted to ground, will send
a pre-programmed message to a particular pager address (which could be to an individual, a group or
all pager operatives at the same time). These messages are pre-programmed and can only be
changed by qualified service personnel.
The trigger time required to send a message must be greater than 1 second.
Individual messages can be sent upon both changes of state with a maximum alphanumeric length of
69 characters.
ConneXions CX6 Mains, Multi Port Version USA

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).
Service Information
If you experience a problem with your equipment you must first telephone your dealer, who may
request that you undertake a few simple checks. If a problem still remains, your dealer will arrange
collection of your system and will endeavour to service or replace the system within 24 working hours
and return the same by overnight carrier.
We suggest that you retain the packaging for your control equipment. Incorrectly packed goods
returned for service are the responsibility of the customer. If we deem that new packaging is required
before we can return the unit, a charge will be made.
In the event that a pager requires service, return it directly to your dealer. Ensure that you carefully
fill out the service form provided. Failure to complete this form in full will result in inevitable delays!

Section 3: Technical Information
This section provides a more in depth understanding of how messages are formatted for serial
communication from a host. It need only be studied by those intending to write their own serial
comm.’s software.
Calling Pagers
Pagers all use 7 digit numeric addresses which enables the system to support thousands of pagers
without identity clashes. Most pagers will support multiple addresses (sometimes referred to as CAP
codes, RIC’s or identities). This enables the pager not only to respond to its own unique address but
also to respond to group or global addresses.
These real 7 digit numeric codes are often substituted for shorter logical numbers which are easier
to remember. Under these conditions the host or speciality program within the transcoder will perform
an algorithm on the data string received to convert the simpler logical number back into a real 7 digit
number for transmission.
For improved data recovery without error the real 7 digit pager numbers are always spaced 8 digits
apart.
To avoid system identity clashes, transcoders are provided with a base number within the range of
1000 to 1,999,000. If for example a base address of 0100,000 is applied to a transcoder, the first
real pager number will 0100,008 followed by 0100,016 and so on.
Logical pager numbers are normally used on systems fitted with the telephone interface and those
which are interfaced to personal computers. The algorithm would perform the following function:-
For example take the logical pager number of 123
The logical pager number 123 will be multiplied by 8 and then added to the base number to provide
the 7 digit real number
Logical No Base No Real No
123 x 8 = 984 + 0100,000 = 0100984
Pager address 1 is normally reserved as the personal identity for that specific pager. Other
addresses, of which there can be 6 or more, can be tagged to specific pagers to form selected
groups. Address 2 could, for example, be used for all pagers to formulate a global call.
Address codes can be divided between full addresses and sub addresses. Full addresses can allow
four different bleep types, A, B, C or D, whereas sub-addresses will only accommodate a fixed bleep
type. A status line of information will normally be provided on the pager screen which will highlight
the type of bleep sent together with other status information.
Numeric Pagers
Example serial message string:-
N0012300A1234567890<CR>
The ‘N’ informs the transcoder that this message is destined for a Numeric pager. Any data not
preceded by this will be ignored.
ConneXions CX6 Mains, Multi Port Version USA
CX6USA Issue 1
Page 14 of 15
Section 3: Technical Information
Next follows the 7 digit pager identity number. All seven digits must be used.
The letter following the identity is the beep type of which there are four valid characters, A, B, C or D.
Next follows the message to be transmitted, which can include:
0-9, space, -(hyphen), ‘U’ (letter U for ‘U’rgent), [,] open/close square brackets, (open square brackets
can also be used to identify the letter ‘C’ for ‘C’ancel). The final character sent is ‘carriage return’
which is not transmitted but represents the end of message marker.
On sending a message to the unit in the correct format the transcoder will immediately recompose
the string into the POCSAG format and transmit the same at the pre-programmed baud rate. This will
be accompanied by the green LED lighting for the same period to show that data is being transmitted.
The time taken to transmit the message is dependent upon the pager baud rate. For 512 baud this is
approximately 4 seconds, whilst at 1200 baud the time is approximately 2 seconds. The unit can
accept sequential data at 9600 baud which will be buffered and dealt with as soon as the preceding
transmission has ended. The RTS line from the transcoder will only go high in the unlikely event that
the message buffer is full.
Alphanumeric Pagers
Example serial message string:- A0012300A This is a message <CR>
The data format is exactly as for numeric pagers, except that the recognition character at the front of
the message is changed from an ‘N’ to an ‘A’.
Transmission baud rate: in the above example, the default baud rate is sent.
To change the transmission baud rate in a message string, placing a letter “N” after the “A” will alter it
to 512 baud. Placing a letter “F” after the “A” will alter it to 1200 baud.
The default setting for the Connexions CX6 is 512 baud.
