The Pliant TMP-B424 Tempest2400 2.4GHz BaseStation is a 4-channel digital wireless intercom system operating in the 2.4GHz band. Using patented Frequency Hopping Spread Spectrum (FHSS), TDMA technology, and proprietary ZSync technology, up to 11 Tempest2400 BaseStations and 55 full duplex wireless BeltStations can be operated in close proximity to each other in a single band while maintaining excellent system performance.
Performance:
The BaseStation comes standard with a single whip antenna (RP-TNC RF connector) and an RJ-45 connector for the (optional) remote transceiver. Redundant data transmission (2xTX) provides time and frequency diversity yielding outstanding RF performance. The CAT 5/6 cable also supplies power to the remote transceiver. An additional RJ-45 enables remote monitoring and control of the entire wireless system over a Local Area Network (LAN) with the aid of the Tempest T-Desk software.
Versatility:
The Tempest2400 BaseStation offers a Stage Announce (SA) output with a relay closure. This is ideal for use with Public Address Systems (PA), city-wide IFB transmitters, or virtually any application that can be triggered with a General Purpose Input/Output (GPIO).
Modes:
Three modes of operation are available within each Tempest BaseStation: Normal, Shared, and Split. This feature allows from five users to hundreds of users depending on configuration.
Expandability:
Utilizing the Tempest system's TDMA technology and proprietary ZSync technology, up to 11 Tempest BaseStations and 55 full-duplex wireless BeltStations (in Normal Mode) can be operated in close proximity to each other within the 2.4GHz band while maintaining excellent
system performance. By switching to Shared Mode, an unlimited number of BeltStations can be connected to one BaseStation.
ZSync Technology:
Available exclusively in the Tempest2400 products, ZSync is a synchronization option that requires the use of an external sync generator. ZSync provides a zero sync reference that coordinates the hopping patterns of all connected BaseStations. This has numerous positive effects. In Seamless Roaming configurations, this allows the BeltStations to know exactly what frequency a given BaseStation is operating on at any given time. This allows for very fast detection and
switching from one BaseStation to another. ZSync is required for all Seamless Roaming applications.
In addition to enabling fast detection and switching in Seamless Roaming systems, ZSync combats turn-on to turnon variation in non-roaming applications. When BaseStations are turned on, the radios start to transmit on frequencies determined by their hopping patterns. ZSync technology ensures that there is a fixed relationship between all of the BaseStation radios every time the system is powered up, irrespective of random time variation in power-up sequences. Assuming that the Network Numbers for the BaseStations have been set properly, there will be virtually no unit-tounit interference, even with up to 11 BaseStations in a Tempest2400 system utilizing Frequency Band 1. This is true for Seamless Roaming as well as non-roaming applications.
