If the future partner device requests a PIN for the connection, this can also be entered using the configuration
programme.
4.4. Changing between Master and Slave modes
Press the key at the rear of the Bluetooth RS232 Adapter to change easily between Master and Slave modes.
Press the key continuously for about 15 seconds. This is then followed by an LED sequence (red – green –
orange) lasting about 2 seconds. Now release the key.
THEN:
The R232 Mini Adapter restarts and flashes red for approx. 3 seconds – the adapter is now in Master mode and it
will attempt to create a connection to the partner device.
OR:
The R232 Mini Adapter restarts and flashes green for approx. 3 seconds – the adapter is now in slave mode and
will accept any incoming connections.
4.5. Notes regarding setting up connection as Master in the event that the partner device does not react
When the RS232 Mini Adapter is configured as the Master, it will automatically attempt to create a connection to
the configured or known partner device.
If this connection fails, there may be several reasons. If the partner device is not switched on, the RS232 Mini
Adapter changes to 'Master idle' mode.
The LED2 then lights up orange.
A new attempt at creating the connection can be initiated by pressing the key.
Note: The LinTech RS232 Mini Adapter can be configured to perform continual attempts at connecting to the
partner device. This setting is recommended when the RS232 Mini Adapter is required to re-establish a
connection which has broken down due to excessive distance.
To do this, you can use either the LinTech BlueTool or the respective AT command (AT+SCMC=1).
4.6. Setting up Master connection
To terminate an existing connection, simply press the key on the adapter briefly.
