Connecting Multiple Receivers To One Antenna - DMX DR500 User Manual

4. Pre-position the antenna to the correct azimuth and elevation
coordinates by using a compass and inclinometer.
5. Pre-position the LNB to the indicated polarity setting.
6. Locate the DR500 Receiver within visual range of the antenna.
7. Connect a 75 ohm coaxial cable (RG-6, typical) from the output of
the LNB to the Receiver RF IN connector.
8. Connect 120 VAC to 15VDC power adapter to the DR500
Receiver – do not turn it on. (Or suitable alternate power source)
Improvise a temporary sun shade over the DR500 front panel as the LED
displays may be difficult to read in direct sunlight.
9. Place the receiver in signal strength mode by depressing channel
up and channel down buttons simultaneously while the power is
off. Alternatively, this may be done with the remote control using
Preset 180. The display reads nL, signifying it is not locked.
— AUTH LED is Off unless the receiver is already authorized
— SYNC LED is Off and remains so until the satellite is
acquired
The signal strength level numbers are preceded by a minus sign
(-) to differentiate them from a music channel number. Signal Quality
readings vary from -00 (the strongest level) to approximately -80
(weakest level) before losing the satellite lock nL.
Rock the dish slowly from side to side and up/down around the nominal
position. When the Satellite has been located, the display will read out a
negative number representing signal strength and the Sync light will
illuminate. Carefully move the dish to maximize signal, at which time the
readout will be the least negative (closest to zero). Tighten the bolts and
check that signal strength has not been disturbed by tightening the bolts.

Connecting Multiple Receivers to One Antenna

Multiple DR500 Receivers can be connected to one antenna. However, to
avoid damage to either the antenna LNB and DR500 Receiver, the
following items must be used:
