Troubleshooting
Q.1 I have power to both Mules but I
can not get any video out of them. I
have all the cameras connected and
outputs connected to the DVR.
A.1 Check the Mules are connected the correct way
around. The transmitter Mule (TX) should have the
camera inputs connected to it and sited at the
camera end. The receiver Mule (RX) should have
the video outputs connected to the DVR and should
be sited at the D
VR end. Make sure that you have
video going in to the TX mule using a test monitor.
Q.2 I have no video output and no power light
lit.
A.2 Check the power supply is connected correctly
to both Mules and outputting 12v D.C. Ensure the
positive cable is connected to the positive port (+)
and the negative cable is connected to the negative
port (-) (figure 1 & 2).
Q.3 The output videos are very grainy and poor
q
uality.
A. 3 You will need to adjust the gain control by
turning the ‘Gain’ control switch on the Mules
(figures 1 & 2). This is done with a flat blade
screwdriver, turn clockwise a fraction on the RX and
review the video output again this may need a few
turns to fully improve video quality. Remember that
the maximum cable length is 200mtrs.
Q.4 I have my audio device connected to the TX
Mule but no audi
o i
s coming out at the receiver
end.
A. 4 Ensure that the audio input is in ‘Video In 2’
(figure 1, 6) on the transmitter (TX) Mule as this is
the only port that will transmit audio. Check the audio
output device at the receiver (RX) end is in ‘Video
Out 2’ (figure 2, 5). Also make sure your audio source
is working ok.
Q.5 My video going into the TX Mule is clear and
bright but the video coming out of the RX Mule i
s
dark.
A.5 Try adjusting the video brightness control. See
step 2 diagrams. Also try adjusting the gain.
Q.6 I can’t get any video out of the units and I
have my RG59 co-ax cable connected to ‘Video
In’ of the TX.
A. 6 Connect the RG59 co-ax cable to the ‘Video
Out’ port on the TX Mule and connect the other end
to the ‘Video In’ port on the RX Mule. You can not
use any other port on the Mules as these t
wo p
orts
are for the transmission of the video & audio between
the pair of Mules. Make sure the cable is 200m or
less and good quality at least RG59 specification.
Q.7 I have all my inputs and outputs connected,
the video going into the TX Mule is clear but the
video coming out of the RX Mule is very poor. My
cable run between both mules is over 200 metres.
A.7 The maximum cable run between the Mules is
up to 200 metres using RG59. You may achieve
l
onger distances using higher grades of cable.
