2.9. Pairing Button
SD1000U provides Pairing Button for instant configuration without a PC to make an automatic
connection between two SD1000Us. In this example we will refer to the two SD1000Us as SD1 and
SD2. (Only single connection mode)
Step 1.
Turn on SD1 and SD2 and reset both of them by pressing Factory Reset Button.
Step 2.
Press the Pairing Button of SD1 for 2 seconds until Mode LED blinks 3 times every 3 seconds.
Keep the power ON.
Step 3.
Press the Pairing Button of SD2 for 2 seconds until Mode LED blinks 3 times every 3 seconds.
Now press again the Pairing Button for 2 seconds until Mode LED blinks every second.
Step 4.
Wait for SD1 & SD2 to connect to each other until the Connect LED’s of SD1 and SD2 blink
every 1 second. It takes about 10 seconds to make a connection. If there are many Bluetooth
devices nearby, it may take longer.
Step 5.
Turn SD1 off and on. Mode LED blinks twice in green every 3 seconds.
Step 6.
Turn SD2 off and on. Mode LED blinks in green every second.
Step 7.
Now SD1 and SD2 are configured to make automatic connection to each other, whenever they
are powered on.
Using a pair of SD1000U in this fashion is similar to that of using a wireless serial cable.
* Note: When using the pairing buttons, the Command Response option will be deactivated
automatically. The SD1000U will not send the response messages such as OK, Connect and
Disconnect.
