Serial 104 - PC/104 Multi-Channel Serial Port Controller

The Serial104 features 8 asynchronous serial communication ports on a single low power PC/104 card providing unprecedented level of serial port integration, performance and flexibility. The Serial104 PC/104 Communications card provides a cost-effective solution for expanding the number of serial ports on a PC/104 system. The Serial104 utilises ultra high performance industry standard UARTs with enhanced features resulting in improved flow control and extremely high data rates. Each one of the 8 channels on the Serial104 may be individually configured for RS232, RS422 or RS485 operation at asynchronous speeds up to 10Mbits/sec. An on-board interrupt controller and flexible address decoding allows the Serial104 to occupy only a single IRQ line on the PC/104 system thus reducing IRQ resource overhead in hardware intensive applications. Because of the flexible address decoding and on-board interrupt controller, a PC/104 system can support up to 2 Serial104 cards thus providing 16 serial channels in addition to the 2 or 4 serial channels giving a total of up to 20 serial ports on the PC/104 stack. The Serial104 is provided with software drivers for the most popular Operating Systems including MSDOS, Windows95/98/NT/CE, and RTOS such as pSOS, QNX, etc.
