IV. Installation and cable
1. Installation
MS-800T main workstation adopts 19-inches 1U cabinet, and this workstation can be mounted on
rack or placed on desktop. If it is placed on desktop, it is required to adhere 4 rubber foot pads
provided with machine to four corners at the bottom of cabinet with double-face adhesive tape.
2. Intercom cable
A). Rules for cable selection
TELIKOU intercom system adopts double-core shielded audio cable, one core is used for
transmitting audio signal, another core is used for transmitting DC power or control signal, and the
shielded layer is used as common line for audio and power supply. To decrease resistance of
common line and crosstalk interference, the cable with larger cross section area should be used.
When it is used in fixed way, the cross section area of single line should be at least 1.5mm
2
, when it
is used in mobile mode, the cross section area of single line should be at least 0.75mm
2
. When the
cable is longer, the cross section area of cable should be larger. If the cable has more than 2 cores,
it is recommended to use the additional core as common line.
B). Cable connection
The standard TELIKOU intercom cable is connected with a pair of 3-pin XLR connectors, one male
and one female. If longer cable is required, you can connect several cables together with head-end
method.
The wiring of connector is as follows:
Pin 1 --- Common (Shield)
Pin 2 --- Power or Control Signal
Pin 3 --- Audio Signal
Notice:
the pin-1 GND connection for each XLR connector must be insulated from cabinet, and
cannot be connected to shell of XLR connector.
