USB / CAT (CI-V) adapter
The circuit design of the USB/CAT adapter is centered around the FTDI FT-232BM integrated circuit, which serves as a bridge between the USB interface and the serial communication required by various transceivers. The FT-232BM is a highly integrated USB to serial UART interface that provides a reliable and efficient solution for serial communication.
The adapter typically features a USB Type-A connector to interface with a computer and a DB9 or similar connector to connect to the transceiver. The FT-232BM chip converts the USB signals from the computer into serial signals that the transceiver can understand, facilitating communication for programming and control.
In addition to the FT-232BM IC, the circuit includes passive components such as resistors and capacitors for signal conditioning and stabilization. A voltage regulator may also be included to ensure that the FT-232BM operates within its specified voltage range, typically 3.3V to 5V, depending on the requirements of the connected transceiver.
The software compatibility with various transceivers allows users to program and control their devices effectively. The successful testing with specific programming software ensures that the adapter can handle the required data rates and protocols, making it a versatile tool for amateur radio operators.
Overall, the design and implementation of the USB/CAT adapter utilizing the FTDI FT-232BM IC provide a robust and reliable solution for interfacing modern computers with legacy and contemporary transceivers, enhancing their functionality and usability in amateur radio applications.Is based on the FTDI`s USB / serial IC FT-232BM. The adapter has been successfully tested with the following transceivers and software: VX-7R (VX-7R Commander), FT-8900 (FTB-8900), FT-817 (FT-817 Commander and Ham Radio Deluxe) and IC-706MkIIG (Ham Radio Deluxe).
