Power supply:

3.1 Voltage: 5~28 VDC, Don’t exceed the limit.
3.2 There’re 3 ways to power the adapter: Mini USB, 2P Terminal Block (Blue), and pin9 of DB9, please choose one. Don’t power the adapter with more than one source.
3.3 The mini USB to type A cable is inside the standard package.

Guide:

4.1 Default value:

• Baud rate: 9,600 bps
•  Data bit: 8
•  Parity: none
•  Stop bit: 1
•  Flow control: none
•  Device Name: Serial Adapter
•  Pin: (None), The value will be authenticated by each other for the S2B2232FIV2 or S2B2232FEV2 only.
•  Mode: Default is “Slave”, The adapter can be configured the “Master” by the command “role=m”.

4.2 If the PC is not built in the Bluetooth, please source the Bluetooth USB dongle or use the same adapter set as the “master”. The built-in Bluetooth of NB supports class 2  only, 10 meters. If you need more than 10 meters in range, you will connect two adapters.
4.3 Slide Switch of “DTE/DCE”
Use the slide switch to swap the “TX/RX” and “CTS/RTS”. By sliding the switch, you can set the adaptor either as a DTE (towards antenna connector) or a DCE (towards  DB9 connector). In most situations, switch to “DTE” if connect with the remote device.
4.4 Slave mode (default): Start the searching from the PC or smartphone and connect it.
4.5 Reset Button: Pressed with a clip or pin into the hole on the top cover. Restore the factory settings (after over three seconds’ press).
