AIRcable Serial
Model 1302
Wireless Bluetooth to Serial Adapter
User Guide
Rev 0.95
December 7, 2004
Thank you for purchasing an AIRcable. Your satisfaction is very important to us, so please read this guide
before installing your AIRcable modules. We’d appreciate your feedback.
For more information and instructions or for support please visit our website at http://www.aircable.net
The AIRcable product is a Bluetooth to serial adapter for cable replacement functions with user accessible
command line for configuration. The AIRcable product is Bluetooth 1.1 certified.
AIRcable modules are intelligent and run firmware-based onboard Bluetooth connection software. There is
no need to install and configure extra software to establish a wireless connection. Because the AIRcable is
designed to replace physical connections, you can run the same software that would support a physical
cable.
Each module has a button accessible through a hole in the device which is used to pair two modules to become a point-to-point
“Wireless Cable™”. During this pairing process, make sure no other Bluetooth device is discoverable within range (approx. 10 meters).
Each module has one power LED (green) which shows that the firmware is running correctly and a connection LED (blue) that shows
the status of a connection. The connection LED is on solid if a connection to another device is active. Otherwise it is blinking or it is off.
The AIRcable Serial is fully Bluetooth 1.1 certified and is compatible with all other Bluetooth 1.1 compatible devices. The AIRcable
Serial is compilant with RS-232 serial industrial standard EIA-232-E. There are two different versions available: The DTE has a Sub-D 9
pin female connector and the DCE has a Sub-D 9 pin male adapter.
The AIRcable Serial supports all modem control signals, including DTR, DSR, and DCD. Data flow control is implemented using
RTS/CTS handshake. Data mode by default is 8 bit, no parity, one stop bit.
NOTE: Because the devices implement hardware handshake, the RTS/CTS lines have to be connected or it must be switched
off. If your device does not support hardware handshake you must switch off hardware handshake with the 4th switch on the AIRcable
switch (down) in order for the AIRcable Serial to work properly.
Pin 9 can also be used for powering the AIRcable Serial module. Apply 5-15V DC, plus to pin 9, GND is pin 5 instead of using an
external power adapter.

Baudrate Selection and Switches
The AIRcable Serial provides switches accessible from the top to select the baud rate. Switch up is on or '1'. Down means off or '0'.
The 4th switch is for hardware handshake. Up means hardware handshake is switched on, down means off.

Configuration
When you receive an AIRcable Serial, the device must be configured.
AIRcable devices support these modes:
Cable Mode
Service Mode
Manual Mode
Cable Mode
In cable-mode, two AIRcable devices are paired together and create a bond so no other device can interfere.
To pair two AIRcables use this simple procedure:
1.
2.
3.
4.
Press and hold the pairing button for 5 seconds. The AIRcable module automatically configures itself and starts in slave mode.
The power LED (green) will be on again and the connection LED (blue) starts flashing rapidly.
Do this on both devices that are going to be paired.
On one device press the pairing button again (short click) to change the mode to master.
At this time the two devices will find each other, pair and establish a connection.
The pairing information has been stored in flash and the two AIRcable modules will connect automatically when they are
powered on. No other device can connect to either AIRcable.
Advanced Modes
The AIRcable Serial can be set into various advanced modes. Use the command line interface to change into these modes.
Service-Slave mode
Service-Master mode
Manual mode
Using the Command Line Interface
The command line interface is available through the serial interface before the AIRcable device is connected. This means that the
connection LED must be either blinking or off.
The serial parameters for the command line interface are fixed at:
• 115200 baud (AIRcable for Motorola is at 57600 baud)
• no parity, one stop bit, 8 bit data, hardware handshake enabled
Use a serial null-modem cable to plug the AIRcable Serial with a male type DB9 connector into a PC.
Each command starts with a “^A” (control-A or 0x1) character, then follows one of the commands listed below in all caps letters and
finishes with a single  (carriage return or 0xd). The command has to be completed within 3 seconds. Otherwise the received
characters are deleted and ignored. All commands respond with an "OK".
Be aware that some commands in some states require the device to reset. They are marked with (*). This process will take a few
seconds during which the AIRcable will not respond to any commands. The power light will go out briefly.
Service-Slave Mode
In the Service-Slave Mode, the AIRcable allows other Bluetooth devices to connect to it. This mode can be used to allow a Palm with
Bluetooth or a Laptop with Bluetooth support to connect. The main advantage of this mode is that it allows several devices to connect
to it as oppose to the previously described point-to-point cable modes.
AIRcable User Manual
Page 4 of 7
In order to switch the AIRcable module into “Service-Slave Mode” use the command line interface detailed below. This is just an
example. Please adjust the commands to the situation you need, including your security needs.
• Reset the AIRcable to the factory default value and delete all pairing information
"^A Z 
• Change the name of the device
”^A N AIRcable ”: set the name to AIRcable. The name has to be exactly 8 characters long. Use spaces to fill up.
• Configure the PIN number. Either a fixed 2-5 digit number or an automatically generated 5 digit ID that will be added to the name to
uniquely identify multiple AIRcables.
”^A P 1234 ”: set pin number to 1234, require authentication
”^A PU ”: generate a unique 5 digit pin number and append it to the name
”^A PD ”: disable authentication, the AIRcable allows connection without PIN. It will keep the pin number and the name.
• Configure the supported Bluetooth profiles (see details below):
”^A DDS ”, set discoverable SPP profile.
• Switch to mode to “Service-Slave Mode”
”^A A3 
Service-Master Mode
The Service-Master Mode is the counter part to the Service-Slave Mode. It can be used as a master to connect to several Bluetooth
devices which are in range, one at a time. The advantage is that it does not require pairing or bonding with the other end. It is a truly
automatic-connect to many other Bluetooth devices. Certainly you can configure automatic pairing with a PIN number of your choice.
For example, it can connect to Bluetooth scanners without pairing it to a particular one. In this case the Service-Master AIRcable would
be configured with the PIN number of the scanner (often “0000”) with authentication enabled and it will automatically connect to the
first scanner it finds. You can change the scanner without changing the configuration.
The Bluetooth Service-Master Mode can also be used to connect to a number of AIRcable devices in Service Mode. This is designed for
field usage where the AIRcable Service modules are stationary and the AIRcable Master-Service is mobile going from one Service
module to another. Again this is an example. Adjust to your needs.
• Configure the PIN number that corresponds to the devices you want to connect to, either a fixed 2-5 digit number or an automatically
generated 5 digit ID that will be added to the name to identify the AIRcable.
”^A P 0000 ”: set pin number to 0000, require authentication
• Disable authentication if the devices you are connecting to don’t require authentication: “^A P D ”
• Switch to mode to “Service-Master Mode”
”^A A4
Manual Mode
The manual mode is designed to give Bluetooth support to devices that cannot run a full Bluetooth stack. The command line interface
is a collection of the simple most common Bluetooth commands. It allows the discovery of other devices, pairing, inbound slave and
outbound master connections and disconnect by software.
You should understand Bluetooth before you can use the manual mode. Please contact us if you have any questions.
Disconnect by Software
Once a connection is established the command line interface is no longer available since all input and output is routed through
transparently to the other end.
In this mode it is possible to disconnect a link programmatically. Depending on the type of device (DTE, DCE or USB) your software
would disable either the DTR or the DSR line, whichever is an input on the AIRcable side.
On the AIRcable Serial DCE (module with male type DB9 connector) the input pin is pin 6 of the DB9 connector (DSR). Once
this pin becomes inactive, the connection is dropped.
On the AIRcable Serial DTE (module with female type DB9 connector) the input pin is pin 4 of the DB9 connector (DTR). Once
AIRcable User Manual
Page 5 of 7
this pin becomes inactive, the connection is dropped.
On the AIRcable USB module, the program should use the DTR line to disconnect the link.
On the AIRcable for Motorola, close the port and it will automatically disable DTR and disconnect.
