Texas Instruments CC2511 - Manual (Page 12)

CC2511 Dongle
When Windows have finished installing the device, a new serial port will appear in the device
manager in Windows. See Figure 9.
Figure 9: Virtual serial port in Windows Device manager
The Windows driver will only work if the “Ti Wireless USB to Serial” is assigned to COM1 to
COM9. (In Figure 9 it is assigned to COM6)
If there are many COM ports installed on the PC, Windows may chose to assign it to a
number higher than 9. If that happens it must be changed. Right click on the “Ti Wireless USB
to Serial” in the device manager and choose “Properties” -> “Port settings” -> “Advanced” to
change.
6.2.3 Running the application
Connect the CC2510EM to the SmartRF04EB and power it. Use the joystick and the S1
button to select the settings for the UART. The settings can only be selected once, if they are
wrong, turn power off and on to reset the CC2510EM and select UART settings again.
These settings only apply to the UART on the CC2510/SmartRF04EB, the settings used on
the Virtual COM port on the PC can be different.
Changing the settings on the CC2510EM/SmartRF04EB will not affect the settings used in the
Virtual COM port and visa versa.
To bind the CC2510EM to the CC2511 Dongle, hold them close together and push S1 on the
SmartRF04EB. The RF protocol found in the CC2511 firmware library uses kiss-binding which
mean that the CC2511 Dongle use the RSSI (Received Signal Strength Indicator) to only
accept bind requests from units that are in close proximity. If the two devices are too far apart
(more than approx 1 meter) the CC2511 will not accept the bind request.
To test the link connect a RS232 cable between a PC and the SmartRF04EB, start
HyperTerminal in Windows (Start -> Programs -> accessories -> Communications ->
HyperTerminal)
Connect one HyperTerminal window to the Virtual COM port, and another HyperTerminal
window to the COM port connected to the CC2510EM/SmartRF04EB.
Text written to one window will be sent to the other one.
