TROUBLE SHOOTING
PROBLEM SUGGESTION
No Link Activity
1. NO POWER – make certain both WEMs have power and
the red Power LED is on. Make sure the connected
Ethernet/IP device is powered.
2. Check the configuration of all WEMs. Each pair and/or all
groups of WEMs setup to communicate with each other
must be set to the same channel. If you have changed any
of the advanced settings, make sure the configurations of all
WEMs being used in the system are the same.
3. Make sure the cable run between the WEM and Ethernet
device is no longer than 300 feet.
4. Make sure the cables being used are straight through and all
cable connectors are attached properly.
5. If using an Ethernet hub or fast switch, try a crossover cable
between the hub and the Power Injector Module.
No Signal Level LED or
Flashing Signal Level
LED
1. Check line-of-sight of the WEMs. Verify the WEMs are
aimed properly. You should have clear, wide-open line of
sight between the WEM modules.
2. Change channels; cycle power.
3. Verify sufficient voltage into each PIM.
Note: The Host AP WEM green signal level LED will flash indicating
the number of Client SU WEMs it is communicating with. This is
normal for this device and should not be confused as lack of signal
strength. The green LED on the Client SU WEM should be solid if
the Client SU is communicating with the Host AP at a full 20Mbps
(50+ Mbps – super mode).
All three solid LEDs but
no picture or picture
drops out after a period
of time
1. Check video at the camera
2. Check wiring into encoders or decoders
3. Try changing channels; cycle power. An uninterruptible
power supply (UPS) may be required and is suggested.
4. Connect one WEM directly into a PC or laptop and verify
that the IP address is accessible. Check the other WEM(s)
the same way, then verify that each IP address is accessible
over the wireless link into a PC/laptop.
5. Verify the connected Ethernet/IP device is configured
correctly.
No Green Signal Level
LED (When Using the
MLWES-30 with two
18” Parabolic Dishes)
1. Verify wide-open line-of-sight
2. Re-angle your dish antenna in a downward angle until both
LEDs are solid green.
3. Mount the dishes higher above ground level and/or above
any obstruction.
