IOGear GBS301 Quick Start - Manual (Page 7)

Using table 1, set the baud rate on the Bluetooth serial adapter
by using the on-board DIP switches. Make sure that this baud
rate matches with that used by your serial device.
If you are unsure what baud rate your serial device uses, please
consult the manufacturer of that product.
Plug in the Bluetooth serial adapter to your serial device. If your
device has a male RS232 interface, use the included null
modem adapter.
When using the Bluetooth serial adapter with a Bluetooth-
enabled device (PC/PDA), you must set the Bluetooth serial
adapter in slave mode (Switch 4 = Off).

Plug in the power cable to your Bluetooth serial adapter; the blue

indicates that the Bluetooth serial adapter is in discovery mode;
in other words, ready to accept a Bluetooth connection.
