Introduction

C104H Series

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. And C104H's versatile OS driver support truly fulfills the needs of our customers' varied applications. The C104H Series offers a reliable and high performance solution for serial multiport communications.
