Descripti on
The Tempest Parallel Zero Sync Generator (PSG) provides a precise, zero reference synchronizati on signal to each
connected Tempest 2.4GHz BaseStati on. This signal aligns the hopping patt erns and transmit/receive ti mes of all connected
BaseStati ons to produce the best possible multi -base, collocated RF performance. BaseStati ons and Remote Transceivers
must contain radios that are version 1.18 or higher to fully uti lize the Zero Reference Sync (ZSync) signal.
The Zero Reference Sync signal that is generated by the PSG (or the ZSync Dongle, sold separately) is a more advanced
synchronizati on signal than has by uti lized previously in Tempest products. Because of this, older Tempest BaseStati ons
and Remote Transceivers must have a radio upgrade to version 1.18 or higher to uti lize the enhanced benefi ts of the Zero
Reference Sync signal. BaseStati ons and Remote Transceivers with radios older than version 1.18 will sti ll accept the new
Zero Reference Sync signal, but they will not have their hopping patt erns aligned as would be the case with radios that are
at version 1.18 or higher. In this case, operati on will be much bett er than not having any Sync signal, but will not be nearly
as good as if the Zero Reference Sync signal was being fully uti lized. To determine whether you have the proper version
radio, refer to the Reference Manual and/or Tech Menu of your Tempest BaseStati on.
A single Tempest Parallel Zero Sync Generator supports up to 12 Tempest 2.4GHz BaseStati ons using the 12 isolated
Sync Out DE-9 connectors on the rear panel of the PSG. Each BaseStati on is connected directly to the Parallel Zero Sync
Generator via a DE-9 extension cable in a star confi gurati on. The connecti on is made from a PSG Sync Out DE-9F to each
BaseStati on’s Base Sync In DE-9M connector. This allows each BaseStati on to receive the proper synchronizati on signal
completely independent of the conditi on or presence of any of the other BaseStati ons.
If more than 12 Tempest 2.4GHz BaseStati ons are required, a second Parallel Zero Sync Generator may be added. In this
case the two PSGs must be connected together uti lizing a Sync Out DE-9F connector on the fi rst PSG to the Sync In DE-9M
on the rear panel of the second PSG. This will allow the synchronizati on of up to 23 Tempest 2.4GHz BaseStati ons.
The Parallel Zero Sync Generator is for use with 2.4 GHz Tempest BaseStati ons only. This product does
not apply to the 900 MHz Tempest model.
