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 DVR end.
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
I have connected my PTZ Dome to the system but can
not control it.
A.3
Check the ‘V4 or RS485’ switch on both Mules is set to
RS845 and not V4 (figures 1 & 2). Ensure the dome telemetry
cables are connected into the TX mule correctly, the positive data
cable is in RS485 port A and the negative data cable is in RS485
port B. Finally check the keyboard is connected to the RX Mule
and again the positive data cable is in RS485 port A and the
negative data cable is in RS485 port B.
Q.4
The output videos are very grainy and poor quality.
A.4
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 TX and
review the video output again this may need a few turns to fully
improve video quality.
Q.5
I have my audio device connected to the TX Mule but
no audio is coming out at the receiver end.
A.5
Ensure that the audio input is in ‘Video In 4’ 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 4’. The ‘V4 or RS485’ switch must be set to V4 and
NOT RS485 (figures 1 & 2).
Q.6
My video going into the TX Mule is clear and bright but
the video coming out of the RX Mule is dark.
A.6
You can adjust the brightness on 1-3 video channels on the
TX Mule, however the video from the RX Mule can not be
adjusted as this video channel is fixed.
Q.7
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.7
Connect the RG59 co-ax cable to the ‘Video Out’ port on
the TX Mule (Figure 1, 6) and connect the other end to the ‘Video
In’ port on the RX Mule (Figure 2, 5). You can not use any other
port on the Mules as these two ports are for the transmission of
the video & data between the pair of Mules.
Q.8
I
have video coming out of 1-3 of the video outputs from
the RX Mule but can not get any video out of channel 4.
A.8
Make sure you have the ‘V4 or RS485’ switch set to V4 on
both the TX and RX mules.
Q.9
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.9
The maximum cable run between the Mules is up to 200
metres.
Q.10
I have my RS485 device connected to the Mules but
the ‘Data’ LED is not lit.
A.10
The ‘Data’ LED is only lit when data is being transmitted
and received.
