| S117P1 is a converter that realizes a serial connection via RS232, RS485, or TTL, using a USB port on the PC. Through the drivers the operating system treats the serial interface like a standard serial port, allowing the use of the converter through any software that can communicate with the standard serial ports present in the operating system (COM1, COM2, etc.). RS232, RS485, and TTL ports are electrically isolated from the USB avoiding most of the problems of electrical noises.
