Section 2 Installation & Setup
2.4.6 Atlas Transmitter
The following applies to either the Atlas Digital DVB-T transmitter or the Atlas Analog
(NTSC or PAL) transmitter as they both have the same Main Controller hardware.
2.4.6.1 Atlas Digital Mounting and AC Power
The eCDi™ can be mounted inside the transmitter cabinet if there is sufficient room. In
this case the ac power may be obtained from TB6 pins 1, 2 and 3 using a standard
moulded ac plug with a pigtail at the opposite end for connection to the terminal strip.
TB6-1 and 2 come from a step down transformer and are therefore interchangeable.
The ac connections to the transmitter are as follows:
•
TB6 - 1 Line/N
•
TB6 - 2 Line/N
•
TB6 - 3 GND
2.4.6.2 Atlas Analog Mounting and AC Power
The eCDi™ can be mounted inside the transmitter cabinet and is actually shown in the
Atlas Analogue Overall Wiring Diagrams which came with the transmitter. The AC
cord for the eCDi™ is prewired into the Atlas Analogue cabinet along with the serial
cable to the controller (W9).
2.4.6.3
Transmitter Serial Connection
For the Atlas Digital, connect the serial port labeled “XMTR” on the eCDi™ to J7 on
the Main Controller Board using the provided 10ft or 50ft serial cable labeled “XMTR”
(either cable can be used depending on where the eCDi™ is mounted).
For the Atlas Analogue, cable W9 is prewired into the cabinet and simply needs to be
connected to the eCDi™ “XMTR” port. See the Atlas Analogue Wiring Diagram.
2.4.6.4 Exciter Connections
No exciter connection required. Exciter information is gathered via the transmitter
controller.
