14 Tempest®24 00 MasterBelt
Set Network Number and Lockout Key
The Network Number determines the frequency hopping patt ern for the MasterBelt and its respecti ve BeltStati ons. This is
a key operati onal parameter and is represented by a number between 0 and 63.
Using diff erent confi gurati ons or systems in close proximity can cause interference and diminish performance. Multi ple
MasterBelt confi gurati ons within the same proximity should maintain a respectable distance from one another and always
uti lize diff erent network numbers.
The Lockout Key prevents systems with the same Network Number from trying to communicate with each other and is
represented by a number between 0 and 255. Together, the Network Number and Lockout Key represent more than 16,000
possible combinati ons to minimize the possibility of inter-system interference.
The Network Numbers and Lockout Keys for Tempest Wireless are set to factory defaults before leaving the factory. Always
adjust the Network Number and Lockout Key of any Tempest Wireless that are known to operate in close proximity to one
another as described below. Users should confi rm these setti ngs to minimize the opportunity for improper performance
issues.
Failure to set a unique Network Number and Lockout Key may result in poor system performance caused by interference
from another Tempest Wireless system using the same Network Number and Lockout Key. Tempest BeltStati ons received
their Network Number and Lockout Key’s from their respecti ve MasterBelt, therefore it is not possible to manipulate
Network Numbers and Lockout Keys to gain unauthorized access to a communicati on channel.
