RS-232 Serial Port Connect the RS-232 port into any computer or serial device. Reset Button Use a tip of a pen or other sharp object to access the reset button. • • To restore to factory default settings: press and hold down the reset button for over 3 seconds to get back to the default settings: - Baud rate: 19200 bps - Data bit: 8 - Parity: none - Stop bit: 1 - Flow control: none - Bluetooth PIN code is "1234" To disconnect and reconnect the wireless connection: press the reset button quickly.
DCE/DTE Switch Use the DCE/DTE dip switch to switch between DCE and DTE mode. Switch to DTE mode, for Data Terminal Equipment (PCs for example); switch to DCE mode, for Data Communication Equipment (Modem for example). Move the switch in the direction of antenna for DCE, and move it in the direction of RS-232 port for DTE.
Hardware Installation 1. 2. 3. Fasten the antenna to the Adapter. Connect the Adapter to the serial port of your PC or serial device. Follow one method below to connect to an external power source: A - Use the included USB cable to connect the Adapter's mini USB connector to a USB port of your PC. B - Use a Powered DB9 connector (Pin 9) as the power supply. This is often used in POS system.
4. 5. Switch the Power Source Switch to "USB/ Battery" when powering up the Adapter through USB or Battery. Switch the Power Source Switch to "DB9Pin9 (5V)" when powering up the Adapter through powered DB9. The Power LED shows steady red light indicating the power is on. Once power is confirmed, go to the next section for COM port configuration and connection. COM Port Configuration 1. Configure the parameters of the COM port through HyperTerminal or other terminal software.
Name OK Figure 6 3. Scroll to choose the COM port you are using to connect with the Adapter, and click OK. Select the COM port OK Figure 7 4. 8 Confirm the parameters as the following, then click OK. To pair two devices for an exclusive connection between them.
Baud rate: 19200 bps Data bit: 8 Parity: none Stop bit: 1 Flow control: None Figure 8 4. 5. Follow the instructions in the next section: "Master/Slave Mode Setup" to set the Adapter mode. Enable the bluetooth function of the PC, search the Serial Adapter and make a connection to it. Master/Slave Mode Setup Set the Adapter to be in "Master" mode or "Slave" mode through terminal software- ROLE command or DIP command. Note: Slave mode is the default setting.
ROLE Command 1. Type ROLE=M to set the Adapter to the master role. (Type ROLE=S to set back to the default.) Figure9 2. Press Enter to see "OK". This means the setup is successful. Figure10 DIP Command 1. The default is DIP=N. Type DIP=Y to turn on the function of the DIP switch, then you can manually adjust the S/M switch to change it to master or slave mode.
Group Mode Setup The adapter is in N/G mode by default. The adapter can be set to G mode if you have more than two RS-232 Serial to Bluetooth Adapters, meaning this adapter is able to perform single to multiple transmission. Follow the steps to set the adapter to Group mode by terminal software: Type DIP=Y to turn on the function of the DIP switch. After the function of DIP switch has turned on, you can adjust the switch to "G".
Setup commands reference table Refer to the following table for more applications: Note: Use all capital or all lowercase letters, do not mix, when typing the commands. Command Value Description <<< Set the local adapter change the data mode into command mode. <<< Switch the data mode to the command. The time interval between each character will be more than the time: [500ms] "<" [500ms] "<" [500ms] "<" [1500ms] <<<= ? Inquire the current setting.
ADDRESS= Used to display the Bluetooth address of t he local adapter. ? Inquire the Bluetooth address of the local adapter. AT Check the connection status between control terminal and the RS-232 adapter. Response: "ERROR" when the connection is not correct. AT Test the RS-232 status when first connect the adapter with the controller. AUTO= Used to enable/disable auto-connection feature. It's available only when the adapter is in master mode. The command is available when DIP=N.
CONNECT= Used to establish a connection manually. It is available only when the adapter is in the master mode. DEVICE Connect the adapter to a specified Bluetooth manually. It's available only when "DEVICE=xxxxxxxxxxxx" is executed. 1~8 Connect the adapter to a Bluetooth device in the Environment which found by "SEARCH=?" xxxxxxxxxxxx Connect the remote adapter by typing the MAC address directly without searching. ? Display the MAC address of the latest paired device.
R Restore the status in which the adapter can connect with any remote address. ? Inquiry the designated address that can be paired and connected. ? Inquire the setting status of the DIP switch function. Y Turn on the function of the DIP switch. The "ROLE" and "AUTO" command are not available to set the "Master" or "Slave". N Turn off the function of the DIP switch. The "ROLE" and "AUTO" command are available when the DIP=N. DIP= (Default) Set the DIP switch function.
Used to specify a name for the adapter. You can specify a friendly name using 0 to 9, A to Z, a to z, space and -, which are all valid characters. (Note: Using Space or - as first or last space isn't permitted.) The default name is "Serial Adapter". NAME= (Default) Serial Adapter Default device name xx....xx "xx...xx" is a character string with the length from 2 to 30. R Restore the default settings name="Serial Adapter". ? Inquire the name of the local adapter.
(Default) Y Prompt result messages. N Don't prompt result messages. ? Inquire the current setting. RECONNECT= Used to re-connect the lost link for the Master adapter. ? (Default) Re-connect is disable Y Re-connect is Enable Used to specify whether the adapter is in the master or slave role. If the device role is changed, the adapter will reboot and all paired addresses will be cleared. The command is available when the adapter is in DIP=N status. The command will have 1 second delay.
Used to specify one or two stop bits of COM port. (Will have 200ms delay.) STOP= (Default) 1 One stop bit. 2 Two stop bits. ? Inquire the current setting. ? Inquire the version codes. VERSION= Used to inquire the firmware version.

FAQ Q: A: 20 My RS-232 device is not connecting to the Bluetooth adapter. Follow the steps below to check if the connections between 2 PCs work well or not. One PC should be equipped with Bluetooth function, and another one needs one available RS-232 port. (1) Connect the Serial to Bluetooth Adapter to the PC with RS-232 port. Configure the parameters of RS-232 Serial to Bluetooth Adapter as following: Role=Slave, Dip switch=DCE(F).
