6. Troubleshooting
In the realm of wireless communications, many factors can affect reliable data communications. This section lists
a number of known factors and possib
le remedies.
If your question is not adequately answered here, visit the SNAP Link support forum on the Synapse Wireless

Signal Strength Problems
SNAP Link adapters should communicate well when placed in near proximity of one another (as indicated by a
mostly green LED A), why might they not communicate well when moved f
uther apart ( as indicated by LED A
turning amber, indicating weak signal strength, or red, indicating loss of signal)? 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 spacial plane, essentially parallel to one another without being directly above or below each
other, try to position the antennas of all your SNAP Link 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 sig
nal
strength improves.
•
Try changing the channel of each device. There are 16 separate channels (0 – 15) spread within the
2.4GHz frequency. Various other 2.4GHz devices, such as cordless phones and WiFi routers, may be
flooding one channel, but not another
one.
•
Refer to the Advanced Management section for reference to the Synapse Portal® software. This
software contains a Channel Analyzer tool that can help you determine which channel has the least
traffic interference.
Multiple Masters
In a multipoint network, if SNAP Link devices are unable to pair with a master, check for the presence of multiple
masters.
There can be only one master in a multipoint network. If you wish to operate multiple masters within the same
vicinity, then be sure to set each master to a different channel and/or network ID using either EasySet or the DIP
switches. To reduce crosstalk, set the network channels as far apart as possible.
When operating normally, a SNAP Link master will slowly blink the A LED, alternating between green and amber.
If it detects the presence of another master on the same channel, it will then alternate the colors between red
and amber.
Can’t Find a Master
If a SNAP Link device is unable to pair with a master, there may be several possible problems:
•
Ensur e there are not multiple masters on the network by observing LED A as described above.
•
Ensure all units on the multipoint network are using the same channel number and network ID.
