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.
