HARRIS CORPORATION CS803 Manual Do Utilizador

 

In Conventional FM mode, the voice path operates like a traditional 
dispatch radio, with a microphone to transmit (push-to-talk) and a 
speaker to receive. The data path operates similarly to the voice 
path, but has a few slight differences. 

In OpenSky Trunked Protocol (OTP), there is no separate voice 
and data path – all transmitted information is digital. The system is 
TDMA based, and operates at a data rate of 19.2 kbps. All data 
information in and out of the control station uses the RS-232 serial 
port. 

The CS-803 Rear Panel Assembly,  Figure  1-1, contains all of the control 
station interfaces. Power to the CS-803 is controlled by an on/off switch 
and provided by a normal AC switched line.  The rear panel also includes 
an antenna port, an RS-232 serial port, an I/O communication port, and a 
CAN port to connect optional OpenSky user interfaces such as the 
SkyPort Desk Set (SP-103), the Control Head (CH-103), and the Tone 
Remote Control Module (TRCM-103) which allows the user to connect 
to off the shelf Tone Remote Desk Sets.  The optional TRCM -103 mounts 
in the back of the CS-803.
