CoachComm Tempest TMP-B424

The Tempest2400 BaseStation is a 4-channel digital wireless intercom unit running in the 2.4GHz band. Operating using patented Frequency Hopping Spread Spectrum (FHSS), TDMA technology, and proprietary ZSync™ technology, up to 11 Tempest2400 BaseStations and 55 entire duplex wireless BeltStations can be used in close proximity to one another in one single band whilst sustaining optimal system performance. When ordering, reference Part Number TMP-B424 (or TMP-B424-EU for European sales). This BaseStation includes a singular whip antenna (RP-TNC RF connector) in addition to an RJ-45 connector for the optional remote transceiver accessory. Redundant data transmission (2xTX) allows time and frequency variety which leads to excellent overall RF performance. The CAT 5/6 cable also powers the remote transceiver. An additional RJ-45 allows for remote monitoring and control of the complete wireless system over a Local Area Network (LAN), with the help of the Tempest T-Desk software. The Tempest2400 also supplies a Stage Announce (SA) output with relay closure.

Tempest TMP-B424 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.

Tempest TMP-B424 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).

Tempest TMP-B424 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.

Tempest TMP-B424 Expandibility:
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.

Tempest TMP-B424 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 turn-on 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-to-unit 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.
