Tempest 2400 Wireless Intercom System

Accu-Sync

Three Base Stations Accu-Synced

Accu-Sync provides a common timing signal between connected base stations. This signal ensures that

transmission cycles for all Accu-Synced base stations occur simultaneously. This synchronized

transmission eliminates the negative RF effect called desensing. See the following section, “Special RF

Considerations for Multiple base stations”, for more information on connecting multiple base stations.

When two or more Tempest base stations are to be operated in the same location, connecting the base

stations via the BaseSync connector on the back of the base station minimizes potential RF interference

between base stations. The more base stations there are in close proximity to each other the more

important it is to use Accu-Sync.

One base station must always act as the sync source when using Accu-Sync. The sync source is any

base station that does not have a BaseSync cable plugged into the BaseSync IN connector. Always

ensure that one, and only one base station has an open (no connection) BaseSync IN connector.

When a base station does not have a BaseSync cable plugged into the BaseSync IN connector, that base

station uses an internally generated timing pulse to control its own transmission cycle.

When a base station has a BaseSync cable plugged into the BaseSync IN connector, that base station

uses the external sync signal (timing pulse) to control its transmission cycle.

The BaseSync signal is enabled by default but can be disabled in the Tech Menu under Radio

Configuration. Unless directed by Tech Support personnel, BaseSync should remain enabled.

The BaseSync cable is a DB-9F To DB-9M wired straight through on pins 1-5.
