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, contact your dealer for further advice.
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).
2
Carefully lift off the cover and set aside.
3
The transmitter should be fixed to a flat wall surface using screws fitted through the key slots
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 attach the unit with No.8 x 1 ½ ”
pan head screws (use wall plugs where necessary). Ensure that the screws are not fully tightened
so that the unit may be readily removed without tools for the purpose of servicing the equipment
.
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.

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 at the Connexions port 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 PL2 on the ConneXions unit
Note: PL1 (25 way D plug) 10 way dry contact interface.
SKT1 (9 way D socket) is not used.
