Important:
If the USB cable is connected between the PTC-IIIusb and the PC, then
Bluetooth is always disabled, USB always has priority! This decision is made
by the PTC-IIIusb at power-on. Do not change the configuration whilst in
operation, always switch off the PTC-IIIusb if you want to swap between
Bluetooth and USB. The USB cable serves you as “switch” in this case.
Locate the PTC-IIIusb near your PC being equipped with Bluetooth (max. 5 m distance).
Start the Bluetooth manager software on your PC. The user interface of the manager may vary
with different brands, so that only the basic operation can be described here.
Let your Bluetooth manager search for Bluetooth devices in range. The PTC-IIIusb should be
found within a short time and be displayed as a
symbol
in the manager. Now you need to
“pair” the PTC-IIIusb with the PC, so that both will recognize each other next time. Usually the
manager offers you the pairing option when you double-click on the symbol, or by right
clicking the symbol. After you have started the pairing, you will be prompted to enter a key or
password. The last 8 characters of the PTC-IIIusb’s electronic serial-number represents this
key. You’ll find the serial-number on the bottom of the modem. Enter the last 8 characters,
which can be numbers and letters, and take care that you enter the letters in upper case. After
you have confirmed the entry, the pairing should have been completed successfully.
Remark:
The pairing might have a limited lifetime and may require to be repeated when
the PTC-IIIusb and the PC have not been connected by Bluetooth for a few days
or weeks. If you use Bluetooth more frequently, repetition of the pairing usually
is not necessary.
After the pairing, the Bluetooth connection can finally be established. This usually happens by
a double-click on the modem’s symbol in your BT-manager. At connection, a virtual COM
port is created and the number of the COM port is usually displayed. Enter this COM number
into the terminal programs you intend to use. From now on, as long as your Bluetooth manager
is operating, starting and terminating the terminal program will also start or terminate the
Bluetooth connection between the modem and the PC. From now on you’re wireless.
Many current Bluetooth sticks come with the Bluetooth manager software
BlueSoleil
. A step-
by-step introduction for this manager with screenshots can be downloaded from our homepage
(http://www.scs-ptc.com).
Limitation:
Because of the fact that Bluetooth does not provide the signals “CD” and DTR” at the virtual
COM port, applications that use the PTC-IIIusb in Hayes-mode (PACTOR-IP-Bridge) may not
work properly with Bluetooth. In this case please use USB. For WeatherFax the most recent
version of GetFAX needs to be used.

Bluetooth Installation
The Bluetooth transceiver is soldered on the bottom side of the main board, on the left front
side, approximately underneath the Bluetooth and USB LEDs. When installed, it is
automatically recognized by the modems operating system and can be used. There is nothing
more to do than soldering it in.
