ConneXions CX9DC DC power, Two Port Version 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.
ConneXions CX9DC DC power, Two Port Version Preface Installation Installation must only be undertaken by an Approved contractor, who shall ensure that all work is carried out in compliance with National Wiring Regulations. For mains powered equipment, a readily accessible isolating fuse or switched socket must be located within 1 metre of the equipment.
ConneXions CX9DC DC power, Two Port Version System Overview The Scope Connexions CX9DC is a 12V DC powered 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.
ConneXions CX9DC DC power, Two Port 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 the immediate vicinity of telephone exchanges or computer equipment. 4 Always use proprietary 50 ohm coaxial cable between the antenna and the transmitter.
ConneXions CX9DC DC power, Two Port Version 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.

ConneXions CX9DC DC power, Two Port Version 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.
ConneXions CX9DC DC power, Two Port Version 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).
ConneXions CX9DC DC power, Two Port Version As a default, contacts are programmed as Normally Open (N/O), with a repeat transmission every two minutes if still active. For customers who wish to connect directly to PL1, the pinout arrangement on the 9 way D plug is shown below: PL1, 9 way D Plug 1 2 3 4 6 7 8 9 5 Dry Contact No. 1 3 5 7 2 4 6 8 GROUND Test Calls: a test call message can be sent every 10 seconds. This feature is very useful for site surveys and range testing. The default is dry contact no.
ConneXions CX9DC DC power, Two Port Version Other Antennas 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. Glass mount antenna (UHFGM): for installation on the inside of a suitable window. This can boost range, especially if it is required in one direction from the building.
ConneXions CX9DC DC power, Two Port Version System Specification System Input Voltage: 12V to 13.8V dc System Power Consumption: less than 50mA standby, 300mA (transmit) Transmitter: Power output: 500mW max Frequency Range: 450-470 MHz Channel Spacing: 25 KHz Adjacent Channel: better than 200nW @ 4.5 KHz deviation TX Baud Rate: 512 or 1200 RF Standards applied: EN 300 224 Type Designation: ECOLINK Notified Body Ref.
ConneXions CX9DC DC power, Two Port Version 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.
ConneXions CX9DC DC power, Two Port Version 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).
