Introduction
 

The C104H Series of multiport serial boards is designed for people looking for an easy-to-use 4-port serial board. Plug the C104H Series board into the appropriate ISA slot, and all configuration tasks will be done automatically, elimintating the need to adjust I/O addresses and IRQ hardware switches and jumpers. C104H is an economical multiport serial board for users who need to control several RS-232 devices, but are unable to do so using the PC's COM1 and COM2 ports.

The C104H Series allows you to install additional RS-232 serial communication ports on your PC by providing 4 serial ports per board for connecting all types of serial devices, including terminals, modems, printers, data acquistion equipment, and more.
