Available exclusively in the Tempest2400 products, the new Seamless Roaming feature enables Tempest2400 users to move freely from a given coverage area to another, with no manual switching between BaseStations required. This capability is powered by the SG-100 ZSync Dongle is a ZSyncT Technology that provides an external zero sync source for multiple Tempest BaseStations.
One ZSync Dongle is required per system to sync all BaseStations in a daisy-chain configuration. Strongly recommended for linking multiple BaseStations.
Radio version 1.18 or later is required. The SG-100 includes an integrated 5vDC wall power supply.
About ZSync Technology
ZSync technology provides a zero sync reference that coordinates the hopping patterns of all connected BaseStations. ZSync technology ensures that there is a fixed relationship between all of the BaseStation radios irrespective of random time variation in power up sequences. All Tempest2400 BaseStations must have the same ZSync reference in order to use the Seamless Roaming functionality.
ZSync generates a zero synchronization reference to enable seamless roaming and to improve performance of multi-base systems in non-roaming applications. The beginning of a hop sequence is indicated with a short pulse (1% duty cycle), while the remaining 5,804 pulses in the sequence use a 50% duty cycle.
