3. Configuration
3.1 Using Promi-WIN™
To configure Promi-ESD, you need to prepare RS232 interfaced jig board.
1. Please connect Promi-ESD to RS232 interfaced jig board you prepared.
2. Connect the Jig board to your Host PC.
3. Supply power to the Jig board.
4. Start PromiWIN software on your Host PC and you may configure the Promi-ESD.
Configuration flow of Promi-ESD is same as the flow of Promi-SD.
Users may consider Promi-SD as Promi-ESD in the manual below.
3.1.1 Making the first Promi-SDTM/Bluetooth connection
To make Bluetooth wireless connections with SD, first connect the SD to a host
computer running PromiWINTM as instructed below. Then activate SD INQUIRY
SCAN and PAGE SCAN from PromiWINTM.
Let’s suppose there are 2 Promi-ESD™s, SD1 and SD2:
1. Connect the SD1 to a host serial port and turn on the SD.
2. Check the SD1 STATUS LED color. Amber indicates standard mode. Start the
PromiWINTM configuration program by clicking the program icon under
Start/Programs/PromiWINTM.
3. Please open PromiWIN ÆPromWIN configuration menu to set up the
PromiWIN to be matched with Promi-ESD.

Check COM port number of your PC where Promi-SD is plugged in.
Check BaudRate/Parity/StopBit. Users need to select the correct
configuration value of Promi-ESD to start.
Default Setting of Promi-ESD: 9600/NoParity/ One Stop bit. Users may NOT
change the configuration of Promi-ESD, the job should be done at
DeviceSetting menu
4. Select Promi-SD ÆStart Configuration in the menu. Information will be
displayed as shown in Figure 1.

the last connected device only.
Mode3: In Mode3, Promi-SD will be discoverable/connectable by any kind
of Bluetooth devices. If users want to make a connection between
Promi-SD and other Bluetooth CF cards or USB dongles, please
set Mode3. For more information, please refer to the Trouble
shooting guide of this manual.
*Promi-SDs which are paired using Mode1 & Mode2 will be
automatically connected, unless Mode setting is changed.
Uart: To change the Baud rate/Parity/StopBit, please use this Uart setting menu.
*NOTE: Please do not confuse with PromiWIN configuration menu.
PromiWIN configuration menu will only set the configuration of
PromiWIN. To Change the configuration of Promi-SD, users must
use this Uart setting menu in Red circle above.
Security Option: Users may set the security option. Authentication/ Encryption/
password.
Device Name: Users may change the device name to be more friendly.
Signal: If users want to remove the response signals from Promi-SD, such as
OK, CONNECT, DISCONNECT, ERROR on each events, users may

turn off the signal here. This can be done by ATS10=n command.
6. Click the ‘Connection(in)’ icon in list control box. Check both options and then
click the ‘Start’ button as shown in Figure 3. The SD1 now starts INQUIRY
SCAN and PAGE SCAN operations. During the operation, the STATUS LED
will flash green, twice every 3 seconds.
Figure 3.
7. After the INQUIRY SCAN and PAGE SCAN setting of the SD1 is finished ,
please plug out SD1. Then plug in another SD to connect to SD1, SD2,
may be connected to the host.
8. Select PromiWINTM and repeat the preceding procedure for SD2
9. Select the ‘Connection(out)’ icon in the list control box and click the search
button.
10. Now the additional SD2 enters INQUIRY operation.

11. From the ‘Search Result’ menu click the item with ‘Promi-SD1’ as its
DEVICE_NAME.
12. Once selected, its BD_ADDR will appear in the dialog box on the right side of
the ‘Connect to…’ button.
13. Click the ‘Connect to…’ button and the ‘Successful Connection’ Popup box will
appear as shown in Figure 5.
Figure 5.
14. To release the first Bluetooth wireless connection between the SD units click
the ‘Disconnect’ button.
15. For automatic connection setup, set SD1 as Mode 2 and SD2 as Mode 1.
To utilize the SD automatic connection feature, make a Bluetooth connection
between two SD units. Once connected, one SD stores the 48-bit BD_ADDR
of its counterpart.

Promi-ESD-02 User Manual ver 1.1
www.initium.co.kr
18
To expedite the 48-bit BD_ADDR input operation, SD is designed to store the
BD_ADDR of its latest counterpart.
3.1.2 Setting Operating Mode for Automatic Connection
New SD units are default set to ‘MODE 0’. For SD automatic connection
change the operating mode of an SD to MODE 1 and another to MODE 2.
The following simple steps describe the SD operating mode change
procedure.
1. After making a Bluetooth wireless connection between two SD units, set the
operating mode of one SD to MODE 1, as shown in Figure 6.
Figure 6.
2. Set the operating mode of another SD to MODE 2 as shown below.

Figure 7.
3. Turn off both SD power supplies. From now, when both SD units are
powered up again, they will automatically connect. (To release this feature,
reset both SD units. Amber SD STATUS LED indicates successful reset
process.)
3.2. Using a Terminal Program
Promi-SDTM units are easily controlled and configured via PromiWINTM . Likewise
functions are accomplished via any terminal program such as HyperTerminal. AT
command sets supported by Promi-SDTM add sophistication to Promi-SDTM control.
3.2.1 Connecting Promi-SD™ to host.
For SD use, follow the simple instructions below:
1. Connect an SD to a host serial port. Then, turn on the SD.
2. Check the STATUS LED color. Amber indicates standard mode.

Promi-ESD-02 User Manual ver 1.1

3. Execute any terminal program and activate Local Echo.
4. Configure the host serial port to match the SD unit configuration. The SD
default configuration is 9600 bps Baud, 8 Data bit, No Parity, 1 Stop bit and
H/W flow control.
5. Enter ‘AT’ command at the prompt. An SD ‘OK’ reply indicates proper
operation.
3.2.2 Making the first Promi-SD™/Bluetooth connection
As stated before, Bluetooth wireless connections can be made with any other
Bluetooth device supporting Bluetooth SPP (Serial Port Profile). For Bluetooth
wireless connections to an SD, first make another SD ‘Discoverable’ and
‘Connectable’. In this case, refer to section 3.3 before following the
instructions below.
1. First check the status of the SD by entering ‘AT+BTINFO?’. The SD
response is comprised of BD_ADDR, Device Name, Operating Mode,
Operating Status, Authentication and Encryption flags. To make connection
to other Bluetooth devices, the operating status of the first SD should be
‘STANDBY’. A ‘PENDING’ operating status of the first SD indicates the
unit is busy with another operation. In this case, cancel the ongoing
operation by entering the ‘AT+BTCANCEL’ command.
2. Search other local Bluetooth devices by entering the ‘AT+BTINQ?’ command.
