ADA-I9141

ADA-I9141 is a device used to convert the USB standard to RS-485/422 without altering the data format being transmitted. The ADA-I9141 converter uses the Rx, Tx, and GND (signal ground) transmission lines for communication with another device equipped with an RS-485/422 interface. It does not require external power – it is powered via the USB port. The converter supports asynchronous data transmission at speeds up to 921600 bps (Profibus up to 1500000 bps). It is a Plug & Play device, which means it is automatically detected by the system when connected to the USB bus. Using a male USB type A connector or a cable with a USB type A connector allows direct connection to the computer. On the RS-485/422 interface side, it has detachable screw terminals. Along with the ADA-I9141 converter, we provide drivers that, when installed, create an additional COM port in the system (Windows 98, ME, NT, 2000, XP, 2003, Vista, 7, 8, 2008). This COM port, with the next available number (e.g., COM3), can be used as a standard COM port. However, this is not a real port existing in the computer but a virtual port created by the system, so some DOS-based programs that reference this COM port may not function correctly. The advantage of the virtual port is the significantly higher data transmission speed compared to a standard COM port, up to 921.6 kbps (Profibus up to 1500000 bps).
