4. Description of indicator and press-button
There are three LED light on the RS232 adapter used to indicate the power state, connect
status and master/slave mode of RS232 adapter. Using mode switchover press-button to
change the working mode of adapter.(data mode or command mode)
Indicator light:
The indicator light of adapter is red/green LED light, power state (red light),
master/slave mode indicator (red light), connect condition indicator (green light).
When the RS232 adapter is powered, the power state indicator light (red light) is always
bright.
If the master/slave mode instructor (red light) blinks every few seconds, it means the
serial port adapter operates smoothly. We can judge this device is master device or slave
device by looking the interval time of lights blinking. If blinking once every 3 seconds, it
is slave device. If blinking once every 6 seconds, it is master device.
If the connect state indicator (green light) extinguishes, that means it has established
connection with other Bluetooth devices. If blinking, it means not establish connection.
When not connecting, we can judge whether it memorize the address (that is whether
matches other Bluetooth device of not) or not through the green light’s blinking speed. If
blinking quickly (twice every second), it means it has remembered the address; if
blinking slowly (once every second) , it does not remember. For master device, it
