ConneXions II V7 SDC DC, Single Port Version Preface Important Safety Information Removal of covers from the equipment must only be undertaken by authorised service personnel, who must ensure that power is isolated prior to removal. Installation Installation must only be undertaken by an Approved contractor, who shall ensure that all work is carried out in compliance with IEE Wiring Regulations.
ConneXions II V7 SDC DC, Single Port Version System Overview The Scope ConneXions II 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 by way of an RS232 serial port. The unit can also be used in conjunction with an optional telephone interface, thereby enabling any telephone within the building or complex of buildings to access the paging system.
ConneXions II V7 SDC DC, Single 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 II V7 SDC DC, Single Port Version 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. If in doubt please feel free to telephone the technical helpline on 01803 860710. 1 Remove the cover from the ConneXions II transmitter unit by slackening the four Pozi head screws located at the top and bottom of the unit (see Diagram 1).
ConneXions II V7 SDC DC, Single Port Version 7 Power input must be 12 to 13.8V dc max. The cable provided plugs into the connector on the bottom panel (see Diagram 1). An integral locking collar is fitted to prevent accidental removal; ensure this is fully tightened. The free end terminations should be connected as follows: + (Positive) = Red wire - (Negative) = Black wire 8 Replace the cover and re-tighten the four retaining screws.
ConneXions II V7 SDC DC, Single 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 II V7 SDC DC, Single 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: DC) for ease of connection to the contact terminals (see Diagram 2).
ConneXions II V7 SDC DC, Single 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 II V7 SDC DC, Single 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 II V7 SDC DC, Single 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).
