These PCI-104 boards feature 8-ports of field selectable RS-422, and RS-485 asynchronous serial protocols on a port by port basis. Ports are accessed via two 40-pin IDC type right angle header connectors. The 104I-COM-8S is feature-rich and allows for the connection of multiple serial devices—ideal for a variety of applications such as POS, gaming systems, retail, hospitality, automation, kiosks, defense industries, high-density networking, or any other application requiring the connection of RS-232/422/485 serial devices to a PCI-104 compatible system. RS-422 and RS-485 modes support data communication speeds up to 1.8432 Mbps. Based on the XR17D158, the boards have eight enhanced 16550 compatible UARTS and include 64-byte transmit/receive FIFO buffers to decrease CPU loading and protect against lost data in multi-tasking systems while maintaining 100% compatibility with all operating system COM port software. Assured Systems offers the 104I-COM- Series of boards in both standard and extended temperature versions ideal for outdoor applications, harsh industrial surroundings, or military use.
