2. Before using the adapter
2.1 For BT-232B-E model, fasten the external antenna to the adapter before performing Quick
Guide 3.1
2.2 Power input (Please chose one): Mini USB cable (Default) or DB9 connector Pin 9 (VCC, 5VDC,
1.5A Max.) or external battery (3~3.7 VDC Li-Polymer Battery or 3 units standard A, AA or AAA
battery)
2.3 Most built-in Bluetooth is in class 2, the 10 meters range, for PC or NB. You will need use the
class 1 adapters on both sides if you need to reach over 100 meters range.
3. Quick Guide
3.1 Using the USB cable provided in the package, plug the mini USB connector into the Bluetooth
RS-232 adapter then connect it to the power adapter with USB or PC
3.2 Turn on the power from the slide switch. The red LED power is on.
3.4 Check the RS-232 setting on 2 sides if they both have the following values:
Baud rate: 19200 bps
Data bit: 8
Parity: none
Stop bit: 1
Flow control: none
If not, please modify the setting by using hyper terminal software and the setup command via
COM port. (See section 11 for the setup commands.)
3.5 Two RS-232 adapter connections in a master-slave environment (See section 3.3 for
illustration). Upon first connection, it is in slave-mode by default and can be set to
master-mode using the setup command (See “ROLE” command in section 11).
3.6 If you are using PC or NB, start the IVT software or the built in Bluetooth management software,
like Toshiba.
