Tempest 2.4GHz Multi-BaseStation Guide – v.1
The Tempest® 2.4GHz Multi-BaseStation Guide
Brief Review of the Tempest Multi-BaseStation
Overview
The Tempest 2.4GHz system is designed to work together to provide a scalable solution for real world wireless
communications.
Connections
Sync.
When using multiple Tempest 2.4GHz BaseStations, it is imperative that all the BaseStations share a
common sync source.
No sync
. This is not recommended for any Tempest 2.4GHz installation using two or more BaseStations.
With no sync source present, the BaseStations will not be coordinated in time or frequency, which can cause
poor RF performance.
Accu-Sync
. Accu-Sync is provided by simply connecting the Tempest 2.4GHz BaseStation ‘Base Sync Out’ of
the first BaseStation to the ‘Base Sync In’ of the next Tempest 2.4GHz BaseStation of that sequence.
Continue to connect ‘Base Sync Out’ of one BaseStation to ‘Base Sync In’ on the next BaseStation until all
collocated Tempest 2.4GHz BaseStations are connected in this fashion. Accu-Sync provides synchronization
only in the time domain, meaning that all connected BaseStations will be transmitting at the same time,
helping to prevent harmful desensing. However, there is no synchronization of frequency(s) that can lead
to a variation in performance, from power up to power up.
ZSync™.
ZSync requires the same connections as Accu-Sync, with the addition of connecting a ‘ZSync
Dongle’ to the first BaseStation in a system with Accu-Sync cables already connected, or ‘Parallel Sync
Generator’ to the ‘Sync’ input of all BaseStations in a system. ZSync provides synchronization in both the
time
and
frequency domain, meaning that all connected BaseStations will be transmitting at the same time
on coordinated frequencies, allowing a total of 11 collocated bases.

Never connect any Sync from a 2.4GHz system to a 900MHz Tempest system
External Hardwire Com
2-wire.
Using the Parallel 3-pin XLR connectors on the BaseStation, any Clearcom Partyline, RTS Partyline*,
or AudioCom Balanced Partyline can be cascaded to all of the 2.4GHz Collocated BaseStations. (*Reminder,
an RTS 2CH Party line connected to Tempest 2.4GHz BaseStation “Channel A” XLR connector will
automatically be assigned to Tempest 2.4GHz Channels A and B.)
4-wire
. Using the RJ-45 connectors on the BaseStation, any analog 4-wire signal can be connected directly
to any of the BaseStations four talk channels. These connections provide a simple, discrete connection for
integration with large matrix style intercom systems, 2-wire/4-wire interfaces, and discrete audio in/audio
