Operating Modes
There are three operating modes for LinkMatik 2.0:
• Auto-Slave Mode, where LinkMatik 2.0 allows
• Auto-Master Mode, where LinkMatik 2.0 tries to
• Command Mode, where LinkMatik accepts
LinkMatik is shipped in Auto-Slave mode with the
PIN code 0000 (four zeroes).
Auto-Slave Mode
In Auto-Slave mode, LinkMatik 2.0 waits for a
remote device to discover and connect to it. No
commands are required, and, unless configuration
commands are sent, no responses are generated
except data from the remote device.
The ESC input would normally be tied low in Auto-
Slave mode unless configuration commands were
to be sent to LinkMatik 2.0.
The ATN output indicates whether the module is in
a connected state. The ATN output will be set
high when a connection is complete and low when
there is no connection. If data is sent while the
ATN is low, it will be interpreted as a command.

also used for:
- Configuring Auto-Slave and Auto-Master
- Audio modes
- Connections to multiple devices

Auto-Master Mode
In Auto-Master mode, LinkMatik 2.0 searches for
any device it has in its list of paired devices and
connects to the first one it finds. A slave and a
master can thus be wedded and require no host
control. No commands are required, and, unless
configuration commands are sent, no responses
are generated except data from the remote device.
The ESC input would normally be tied low in Auto-
Master mode unless configuration commands
were to be sent to LinkMatik 2.0.
The ATN output indicates whether the module is in
a connected state. The ATN output will be set
high when a connection is complete and low when
there is no connection. If data is sent while the
ATN is low, it will be interpreted as a command.
Command Mode
In Command mode, commands are sent to
LinkMatik to control it.

modes are detailed in this document.
Refer to the LinkMatik 2.0 Command Reference
DS389-1
commands available in command mode, including
audio mode commands.
Configuration Commands
Sending Configuration Commands
To send commands for configuration purposes (as
opposed to host control), connect LinkMatik to a
serial
HyperTerminal. Commands should be terminated
with carriage return and linefeed characters.
If required, FlexiPanel’s Pixie Config Tool can be
used to convert between USB and TTL serial
signals in order to make the connections. If used
to connect to the SO module, however, care
should be taken to clamp the TxD maximum
voltage to 3.3V using a circuit such as shown in
figure 4. The tool has no flow control, so CTS is
connected to RTS.
To ensure all commands take effect, reset
LinkMatik 2.0.
