same time. Only use one or the other. Plugging in both the USB cable and AC power 
adapter may damage the USB port on your PC or USB device. 
 
Below is a simple example to show how the Radicom Bluetooth modules work. This 
example demonstrates how the Bluetooth Modules can connect to each other.  
 

1.  RB4000MB-SPP-A Initiator setup: Open HyperTerminal and select an available 

Serial Comport. Set the DTE speed to 115200bps, 8 Data bit, No Parity bit, One 
Stop bit and No Flow control. 

2.  Connect one end of the RS232 Null modem cable (DB9 Female to DB9 Female) 

to the Serial Comport and the other end of the cable to the RB4000MB-SPP-A 

3.  Apply power using either a USB cable or Optionally provided AC power adapter 

to RB4000MB-SPP-A. The modules Firmware message should show up on the 
HyperTerminal screen and the LED on the RB4000MB-SPP-A should be ON. 

4.  RB4000MB-SPP-B setup: Open HyperTerminal and select an available Serial 

Comport. Set the DTE speed to 115200bps, 8 Data bit, No Parity bit, One Stop bit 
and No Flow control. 

5.  Connect one end of the RS232 Null modem cable (DB9 Female to DB9 Female) 

to the Serial Comport and the other end of the cable to the RB4000MB-SPP-B.  

6.  Apply power using either a USB cable or Optionally provided AC power adapter 

to RB4000MB-SPP-A. The modules Firmware message should show up on the 
HyperTerminal screen and the LED on the RB4000MB-SPP-B then start blinking. 

7.  When both Modules are powered-up, they should automatically connect to each 

other as long as the modules are within acceptable distance, for example, 10m in 
home or office).  

8.  The on board LEDs will show the modules Connect Status. 
  

 
Note(s): They further apart the modules are, the longer it may take to connect and the 
slower the data transfers will be. If the modules do not connect make sure that the 
firmware displayed reflects that one module contains Initiator firmware and the other 
module contains Acceptor firmware. For example, the Initiator should display SPP-B 
XXX and the Acceptor should display SPP-A XXX where XXX is the firmware version.

Note: When Connected and no data activity, the modules will enter lower power Sniff 
Mode after 5 to 7 seconds of inactivity. Any transmitted or received data will cause the 
module to exit Sniff Mode and resume normal operation.
