INSTALLATION PROCEDURE
Connecting to a Host PC
To use the dongle to provide serial communication between other Bluetooth device and a
host PC:
1. The dongle serial port connector can be connected directly to the serial port of a
host PC. However, in situation where connection is difficult or better wireless
reception is desired by keeping the dongle away from the host PC, the serial
cable can be used.
2. Connect the male end of a serial cable to the dongle serial port.
3. Connect the other end of the serial cable to the host PC.
(Note: The dongle requires a dedicated serial port on the host PC. It cannot share a
port with an internal modem or other device)
4. Power up the dongle following the procedure outlined in Connecting to Power
Source.
5. The Host PC is ready to receive data from other Bluetooth devices through the
serial port with the serial port settings matching that of the GWT-SPP1. The
GWT-SPP1 has an interface configuration of baud rate 115.2kbps, using 8-bit
data with 1 start and 1 stop bit.
Connecting to Power Source
The AC-DC adaptor provides power to the GWT-SPP1 dongle. Use only a GWT-approved
power adaptor with output rated 4.5V DC and minimum current of 0.2 Ampere.
To connect the power source to the dongle:
1. Connect the DC out put of the AC-DC adaptor to the power port of the dongle
located at the side of it.
2. Connect the other end of the AC-DC adaptor to a wall outlet.
3. Switch on the wall outlet and checks that the green LED is lighted (see Using the
LEDs for more information).
