Troubleshooting
In the realm of wireless communications, various factors can affect reliable data
communications. This section lists several known factors and possible remedies.
Signal Strength Problems
SNAP DMX adapters should communicate well when placed in near proximity to one
another, but might not communicate well when moved farther apart (as indicated by LED
A not consistently indicating green for DMX traffic on the receiving device). You can
make several adjustments to remedy this situation:
‣
Try orienting the external antenna into different positions. Since antennas work
best when they are in the same spatial plane, essentially parallel to one another
without being directly above or below each other, try to position the antennas of all
your SNAP DMX devices in the same orientation.
‣
There could be other interference problems in your vicinity such as large metal
objects, dense foliage, and other objects that prevent signal transmission or
attenuation (signal loss). Microwave ovens can cause interference problems. Try
moving the units physically to another usable location to see if signal strength
improves.
‣
Try changing the Universe of each device. There are 16 separate Universes (0 – 15)
spread across the 2.4GHz frequency band. Various other 2.4 GHz devices, such as
cordless phones and Wi-Fi routers, may be flooding one channel, but not another
one.
Odd Performance
If you believe your SNAP DMX adapter is not performing adequately, you should
consider the following instances:
‣
Poor signal strength – try adjusting the antennas as described above.
‣
Incorrect Universe assignment – try setting the Universe again; while in Universe
Configuration Mode, make sure that LED B & C light up the same way on all units
to make sure they are assigned the same Universe number (0-15) as shown in
Figure 2: LED B & C Color Chart
‣
Incorrect Security Key has been assigned – While stepping through each Security
Key Configuration Mode, verify that each SNAP DMX adapter has the same
security key set for each of the four Security Key Modes.
