Sistem untuk Melakukan Konversi Protokol IEEE1284 ke RS-232 protocol melalui Koneksi Bluetooth

Abstract

There are many applications which requires the use of embedded device and legacy hardware device in Indonesia. Most of this legacy hardware communicates with embedded device utilizing an obsolete interface technology such as IEEE1284 which is considered less convenient compared to bluetooth technology. However, most embedded devices support the use of basic interfacing technology such as RS-232. This research attempts to solve the problem by developing a device to communicate and control IEEE1284 device from a RS-232 port over bluetooth technology. The prototype utilizes two microcontrollers for converting IEEE1284 protocol to RS-232 and two bluetooth communication modules for transmitting and receiving data between the two microcontrollers. The evaluation of the prototype shows that it has successfully established bluetooth communication between the IEEE1284 device and the embedded device. The microcontrollers have successfully control IEEE1284 device from RS-232 port by converting RS-232 protocol to IEEE1284 protocol over bluetooth connection. The constructed prototype has one hundred percent success rate according to 32 times of test performed on it.
