DIP Switches:
NOTICE: The DIP switches must be set to the desired positions before the adapter is turned on.
DIP / S/W
• Position “DIP”: The adapter is using the parameters set by the DIP switches. IMPORTANT: The DIP switches should be
set in the desired positions while the adapter is turned OFF only. The reason is that the adapter ‘reads’ the DIP
switches only in the moment the adapter is turned ON.
• Position “S/W”: The adapter is using the parameters set by software (by default the PROMPT AND ECHO parameters
are enabled in this position).
Run / Config
• Position “Run”: The adapter is in Run mode and ready to use.
• Position “Config”: The adapter is in configuration mode and the parameters can be configured over Bluetooth or
through the serial port.
Slave / Master
• Position “Slave”: The adapter is in Slave mode.
• Position “Master”: The adapter is in Master mode.
IMPORTANT NOTE: The parameters cannot be configured over Bluetooth when the adapter is in Master mode.
DIP switches Baud rate settings Indication lights
DCE/DTE switch Power source selector USB for power

Auto / Manual
• Position “Auto”: The adapter will automatically connect with a Slave adapter. This only works if the adapter is in Master
mode.
• Position “Manual”: Master and Slave will need to be connected manually with the 'CONNECT' command.
Flow Off / On
• Position “Flow On”: Enables the flow control signals (CTS/RTS)
• Position “Flow Off”: Disables the flow control signals (CTS/RTS)
Baud
The four Baud DIP switches sets the adapters baud rate in accordance to the pictogram shown on the front of the
adapter.
Reset Button:
 Short press: The adapter disconnects and then reconnects a wireless link
 Long press (more than 3 sec.): Restores factory settings
Indication LED Status:
Status Description
Power/Batt Indicates when the adapter is powered ON either by the
internal battery, USB or pin 9.
Status LED off No pairing
Status LED fast (0.1 sec) blinking Pairing (slave or master mode)
Status LED fast (0.3 sec) blinking Discoverable and waiting for a
connection (slave mode)
Status LED slow (0.9 sec) blinking Inquiring (master mode)
Status LED very slow (1.2 sec) blinking Connecting (master mode)
Status LED steady on Connection established (COM port open). This light does
NOT get steady ON when the adapter is paired, only when
the COM port is open/active.
TX Flash when data is transmitted
RX Flash when data is received
Charging Solid on: Indicates that the internal battery is charging.
Flashing: Indicates that the battery is low. Less than
10% power remains.
Power and Flow Switch:
On the side of the Blutronium adapter there are two switches and one mini USB port which has the following functions:
Power switch: “USB/Batt” / “Pin 9”, (power input selector).
This switch has 2 settings: “USB/Batt” (3.3 – 5 VDC) and “Pin 9” (4.8 – 24 VDC). When the switch is in the “USB/Batt”
position the adapter is powered by the USB power source, if a USB power source is connected to the adapter. If no USB

Blutronium™ Serial Bluetooth Adapter – Datasheet & Quick Reference www.USconverters.com
www.usconverters.com Page 6
power source is connected to the adapter then the adapter will automatically be powered by the battery.
The battery can only be charged when the switch is in position “USB/Batt”.
When the switch is in “Pin 9” position the adapter is powered by pin 9, provide there is a power source connected to pin 9.
Flow switch: “DCE” / “DTE”.
This switch changes the RS232 port between a DCE type interface and a DTE type interface.
USB mini power port.
Power input only w/o data communication.
Command List and Configuration
The parameters can be configured over Bluetooth or through the adapter’s serial port by using the Blutronium Configuration
Utility which can be downloaded from https://www.usconverters.com/activate, or by sending AT commands to the adapter.
Please see the 'Setup Guide' for how to setup and use the adapter and Configuration Utility.
If configuring by sending AT commands please refer to the table below.
Note 1: Commands should be typed in either all CAPITAL letters or all lowercase letters.
Note 2: Commands cannot be received by the adapters if they are paired/linked, only when the adapter is in command
mode.
