LED Indicators See Figure 1 for the location of the LEDs. Please refer to the following chart for the status of LEDs. Status Description Power LED off/ on No power supply./Power input is equal or larger than 3.5 Volt Power LED blinking Power input is lower than 3.5 Volt (See command DETECT) Status LED off/ on No pairing established./ Connection established. Status LED fast blinking 0.1sec- Pairing (slave or master mode). 0.3sec- Discoverable (slave mode). Status LED slow blinking 0.
RS-232 (Serial) Connect the RS-232 port into any computer or serial device, see Figure 3.
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 disconnect and reconnect the wireless connection: press the reset button quickly.
Hardware Installation 1. 2. Fasten the antenna to the adapter and connect it to serial port of the PC. Power on. 2.1. Plug the included mini USB connector into the adapter's USB connector, then connect it to the PC. You can also choose from the following options. Powered DB9 connector (Pin 9): Often used in POS system. Powered by external battery: Three Standard A/ AA/ AAA batteries, or one Li-Polymer battery (3~3.7VDC). 2.2. Switch the Power Source Switch to power on the Bluetooth adapter.
COM Port Configuration Guide 1. Configure the parameters of the COM port. 1.1. Enter Hyper terminal or other terminal software to configure the adapter. Program> Accessories-> communications -> Hyper Terminal 1.2. Type in "Name", then click OK. The name is defined by yourself.
1.3. Scroll to the COM port you are using to connect, and click OK. 1.4. Confirm the parameters as the following, 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 1.5. After finishing settings, click OK to store it. The adapter should start connecting automatically, and the status LED will start blinking.
2. Set up the slave / master mode. This is for identifying the role of the device as a master or slave. Select Master, for DTE mode, for Data Terminal Equipment (ex: PCs). Select Slave for DCE mode, for Data Communication Equipment (ex: Modem). When you have two RS-232 Serial to Bluetooth Adapters, you have to set one in master mode via the terminal software. The adapter is in slave-mode by default, and you can choose either way to set the mode: 2.1. Using the ROLE command.
2.2. Using the "DIP" command. 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. 3. 4. 10 DTE & DCE Switch. Use the DTE/DCE Switch to swap between DTE/DCE. By switching, you can set the adapter as a DTE (towards antenna connector) or a DCE (towards RS232 connector). Set up the Group mode. The adapter is in N/G mode by default.
5. 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. Besides the basic settings, you can check the following table for further applications: Note: Use all capital or all lowercase letters 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.
ADDRESS= Used to display the Bluetooth address of the local adaptor. ? Inquire the Bluetooth address of the local adaptor. AT Check the connection status between control terminal and the RS-232 adapter. Response: "OK" when the connection is ok. 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 is available only when the adaptor is in the master role.
Used to establish a connection manually. It is available only when the adaptor is in the master role. CONNECT= DEVICE Connect the adapter to a specified Bluetooth device manually. It is available only when "DEVICE=xxxxxxxxxxxx" is executed. 1~8 Connect the adapter to a Bluetooth device in the Environment which found by "SEARCH=?" xxxxxx- Connect the remote adapter by type the MAC address directly xxxxxx without searching. ? Display the MAC address of the latest paired device.
R Restore the status so the adaptor can connect with any remote address. ? Inquire the designated address that can be paired and connected. DIP= (Default) Set the DIP switch function. ? 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.
Used to specify a name for the adapter. You can specify a name by using 0 to 9, A to Z, a to z, space and -. (Note: Using Space or - as first or last character isn't permitted.) The default name is "Serial Adapter". NAME= (Default) Serial Default device name. Adaptor 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 adaptor. Used to specify parity bit setting of COM port.
(Default) Y Don't prompt result messages. ? Inquire the current setting. RECONNECT= (Default) Used to re-connect the lost link for the Master adapter. ? Inquire the current setting. N Re-connect is disable Y M Set the adapter to the master role. S Set the adapter to the slave role. ? Inquire the current role of the adapter. ? Display the strength of signal received in command mode when connected. 1. Strong: RSSI>-9 2. Medium:-9>RSSI>-20 3.
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.
