Carefully lift off the cover and set aside.

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
).

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.

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.

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”.

Replace the cover and re-tighten the four retaining screws.

Finally, after checking all connections, insert the supplied DC connector & cable into the
DC
power inlet
located at the base of the unit and connect to a regulated 12V dc power source
capable of delivering at least 2.5A. With 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.
