Network Number and Lockout Key
The Network Number determines the RF frequency hopping paern for the BaseStaon and its BeltStaons. This is a key
operaonal parameter and is represented by a number between 0 and 63.
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 over 16,000
possible combinaons to minimize the possibility of inter-system interference.
The Network Numbers and Lockout Keys for Tempest Wireless BaseStaons are set before leaving the factory, by
incremenng by one digit. Always adjust the Network Number and Lockout Key of Tempest BaseStaons that are known to
operate in close proximity to other BaseStaons as described below. Users should conrm these sengs to minimize the
opportunity for “mysterious” 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. Because of the requirement to
pair every BeltStaon to each BaseStaon that it will communicate with, it is not possible to manipulate Network Numbers
and Lockout Keys to gain unauthorized access to a communicaon channel.
Mulple BaseStaons in Close Proximity
The Network Numbers of closely located BaseStaons should be oset by at least four, for maximum performance. For
example, on Base-A select Network Number “02”, on Base-B select Network Number “06”, and on Base-C select Network
Number “10.” In this manner each BaseStaon Network Number is dierent by at least four digits. This procedure will
ensure that each system is operang properly and independently from an RF network perspecve.
Also, adjust the Lockout Key on each BaseStaon. All BaseStaons in one facility may have the same Lockout Key if all
Network Numbers are oset by four as described above, or all may be dierent. Lockout keys are only dierenators for
systems using the same Network Number.
The Network Number and Lockout Key sengs can be adjusted from the “Radio Conguraon” secon of the Tech Menu.
Press the MENU buon. Press the ENT buon to select “BaseStaon Sengs.” Rotate the Volume control to scroll and
select “Tech Menu.” Select “Radio Conguraon.” Select “Network Number.” Rotate the Volume control to adjust the value
and press ENT to save.
Press MENU to escape one level and select “Lockout Key.” Adjust the value and press ENT to save. Press MENU repeatedly
to escape to the Operaon screen.
