Page 6: Cl4790 Rf Transceiver
CL4790 transceivers operate in a Masterless architecture. When a CL4790 has data to transmit, it will enter transmit mode and start transmitting a sync pulse intended for an individual radio or broadcast to all transceivers within the same network and range. Intended receivers synchronize to this sync pulse, a session begins and data is transmitted. -
Page 7: Theory Of Operation
The LINK LED on the CL4790 illuminates to show that it is In Session. A transceiver enters Transmit or Command mode when the OEM host sends data over the serial interface. -

Page 12: Programming The Cl4790
All CL4790 units ship with a default baud rate of 57600 (unless units have been pre-configured to match specific serial settings). If the Interface Baud Rate of the CL4790 unit is changed, the PC Setting baud rate must match the device baud rate to allow proper programming of the units. -
