7. Usage
If amendment of the parameters are needed, please move Cmd Data Switch to
Cmd side until the completion of parameter setting, and install related parameters via
the "AT command" or "parameter setting tool", such as parameters for principle/
subordinate equipment, baud rate, authentication and address binding. If the
communication is between two RS232 adapters, you should make an equipment the
principle one, and another one subordinate. Please move the Cmd Data to the Date
side after finished.
After starting the equipment up, if no memorized addresses are saved, search
nearby Bluetooth equipment first. If searching out, the principle equipment would
enter into matching state. If authenticating right, the principle equipment would
memorize (save) the address, and establish links with the equipment. If linking
success, LINK light twinkles one time every five seconds; if having memorized
addresses yet, the principle equipment connects directly with the memorized
equipment without inquiries and matching. The memorized address could be deleted
by using the AT command and parameters setting tool.
As for subordinate equipment, which wait for being connected and searched by
other equipment, its LINK light twinkles every five seconds, if connecting
successfully.
