4  Connecting the adapter 

4.1  Connection to the RS-232 device 

 
For most target devices, the Bluetooth adapter can directly plugged into the corresponding 
D-sub connector of the device. When the target device has a female DE-9 connection, the 
yellow „gender changer“ adapter (included in the delivery) has to be used.  
 
If the target device has a standard pin-

out, the „DCE-DTE“ switch can 

be used to switch the adapter between emulating a DTE (data terminal 
equipement, e.g. a computer) or a DCE (data communication 
equipment, e.g. a modem). In particular, this swaps the send (TxD) and 
receive (RxD) lines of the adapter. 
 
If the target device has an unconventional pin-out, the proper interface 
cable has to be used to connect the device to the adapter. 
 

 

When connecting the adapter to a regular computer, the adapter can be plugged 
in directly and the DCE-DTE switch has to be set to DCE. 

 

4.2  Powering the adapter 

 
The Bluetooth adapter can be powered using one of the following methods: 
 

a) 

Using the included plug-in power supply:

 

 
Install the proper country-specific plug into the power supply. Connect the cable 
with the USB Mini-B connector of the adapter. Then plug the power supply into the 
mains.  
 

b) 

Using an USB connection: 

 
You can power the adapter from regular USB port by using a USB A to Mini-B cable 
(included). 
 

c) 

Using the RS-232 

port‘s Pin 9:

 

 
The adapter can be powered directly over the RS-232 interface. This requires that 
the target device provides a voltage in the range of 4V 

– 13V (max. 90mA) on pin 9 

of the RS-232 port. 
For the configuration of the adapter, the adapter still can be powered over the USB 
port.
