1 Introduction

The Smart 3 in 1 Multiport Async Solutions

The C114HI is a RS-232/RS-422/RS-485 4-port serial communication interface

board. Each port can be configured to RS-232, RS-422 or RS-485 individually. It is

designed for the system manufacturers, integrators or VARs that want to provide all

high performance, reliability and quality multiple port data communication system.

The C114HI provides a low cost, high performance solution for connecting up to 4

devices such as terminals, modems and printers to PC-based host computer. It

belongs to the C104 family and features high speed and isolation protection.

The C114HI is so flexible in configuration that they are compatible with virtually all

kinds of other manufacturer's 4 port non-intelligent boards using 16C550C UART.

Operating System Support

The family is operational under most popular operating systems such as Windows

NT, Windows 95/98, SCO UNIX/XENIX/OpenServer, DOS, Windows 3.x, OS/2,

Linux, QNX, FreeBSD, MUMPS, PICK OS, IMS Multiuser DOS, etc. However,

MOXA device drivers for Windows NT, Windows 95/98, DOS, Windows 3.x and

Linux are provided for better installation, configuration and performance. In this

manual, chapters for MOXA Windows NT,Windows 95/98,DOS and Windows

3.x device drivers are included. For other compatible systems not mentioned, please

refer to the respective operating system’s manual for how to install and configure

the standard driver.
