The Stratus Controller listens to all incoming data from every connected radio site and every console. Each
connection (from site to site or console to site) uses routing rules confi gured in the software to decide on the routing
path. These routing paths are determined by NAC or Talk Group ID. Each connection can use diff erent mapping.
The Stratus Controller has the capability to convert from any NAC to any Talk Group ID and vice versa. This allows
for any combination of mapping (affi liating) between all sites using any type of P25 code.
Local repeating (at the repeater site) will repeat ALL NACs since the receiver is programmed for $F7F at all
sites. Local Repeating can be done through the Stratus Controller however, latency (200 – 700 ms depending on
complexity) can occur.
Each site can allow ALL Unit IDs, or can be programmed to allow specifi c Unit IDs per site. The Stratus Controller
is not capable of routing based on Unit ID, but will block Units from sites.
The Stratus Controller has the following capabilities / features:
• Create an FSI Fixed Station connection
• Create an FSI Gateway connection
• Register P25 Talkgroups
• Register P25 Subscriber units
• Confi gure audio to be routed between specifi c FSI connections
• Using NAC based routing
• OR Talkgroup based routing
• Translate NAC codes for re-broadcast
• Log call activity and errors (playback not yet available)
• Forced remote reset
• Backup / Restore confi guration fi les
• Update Firmware
• Buff er and correct network voice issues (with limitations)
• When used with a Codan UIC card
• Control channel selection
• Local repeat / No repeat / Stratus Controller repeat selection
• Read 9.5 VDC and 13.8 VDC voltage inputs
• Read 4 Analog and 4 Digital General Purpose I/O (GPIO) status
• Report Rx / Tx Status (Active / Inactive)
