How to hook up a C-Band Satellite receiver
The illustration below is typical. The location of the terminals illustrated
below might be in a different location on the back of your receiver but these circuts will be there somewhere. Look in
your owners manual and the back of your receiver to identify where they are
located on your receiver.
These basic directions include most IRD receivers manufactured after 1986.
We will start with the motor circut.
Your wiring will have two large 12-14 gauge wires usually white and black or
red and black. These wires would go to M1 and M2 on the back of the receiver.
The terminals they go on depends on how it is wired at the actuator motor on
the dish there are M1 and M2 terminals there. Normally white or red would go to
M1 and black to M2. If you get these backwards the dish will go East when it is
supposed to go West. There are two smaller wires usually 22 gauge that go on
the sensor and ground terminals of the motor circut in any order. To find out
which two smaller wires are being used you might have to take the actuator
motor cover off at the dish to see which wires are being used (there are more
than two small wires in the wiring bundle usually there is a green, blue,
brown, sometimes white, and a bare twisted wire. Some installers have used the
bare wire as the ground wire in the sensor circut this will work but is not
desireable so change this to a colored wire if this is how your circut is
wired. )
Polarity circut
The polarity wires will be in a bundle of three 18-22 gauge wires almost always
red, black and white. They hook to the polarity circut on the receiver, white
goes to the terminal marked pulse or sensor, red to the terminal marked 5+ and
black to the terminal marked ground. On the dish these wires hook to the feed
horn servo motor and match up to red to red, black to black and white to white
Video-if-Circut
The coax between the receiver and the dish. Mounted on the dish (usually under
a cover is the lnb(s) and the feed horn. On the dish the coax is connected to
the lnb or lnbs. If you have only one lnb you have a c-band only system. If you
have two lnbs and one is smaller than the other you have a C/KU/band system. If
you have two lnbs and they are the same size you have a dual lnb C-Band only
system (usually used on systems with more than one receiver). If you have
single LNB system you connect the coax comming from the LNB to the connector
labled one of the following, "(IF input) (lnb) (lnb input)(C / H) If you
have a c/ku/band system you will have two coaxes to connect on the back of the
receiver. The C-Band LNB coax goes on the same terminal as above and the K/U
band LNB coax goes on the terminal below the first one labled one of the
following, (V / KU) (Verticle / KU). If you have a dual LNB C-Band system you
would put the horizontal LNB coax on the top terminal and the verticle LNB coax
on the bottom terminal. Receivers will have a place somewhere in the
installation menus to select the feed horn lnb set up
Please note some receivers have only one LNB input and
still have dual LNBs or C/Ku, they have an out board switch that you attach the
incoming LNB coaxs to and then a single coax goes from the switch to the LNB
input.
