1-1. Overview

Thanks for purchasing Universal PCI / PCI-E Industrial Multi-Port Communication Card. The Multi-port serial card

equips with 2, 4, or 8 independent DB9 or DB25 RS-232/422/485 high-speed serial ports which accessed through DB-9

or DB-25 male connectors for industrial communication and automation applications. Each serial port has built-in 64byte

hardware FIFO, on-chip hardware flow control, provides baudrate speed up to 921Kb/Sec and also compatible with the

popular 16C750/16C550/16C450 UART controller.

1-3. Product Features

New Design of Matrix UART controller

Matrix is a highly integrated multi-port UART controller that includes all of its functions into a single chip. In addition to

those functions provided by a standard 16C750 UART chip, it also equips lots of advanced features that make the serial

communication much more reliable and easy to use.

With the large buffer and special designed flow-control circuit inside the chip, it could provide the transfer speed up to

921Kbps for each port. Highly integration makes the response time much fast and consumes little power dissipation even

when it is worked at full speed. Those features together make it suitable for those applications that require low latency,

real-time control, high reliability and low-power environments.

The Matrix is ideal for POS system, industrial automation, data collection and any other applications that require serial

connection.

Sunix Proprietary AHDC/CS for Automatic RS-485 Direction Control

In the early days, RS-485 transmission required manual switching of the direction of the line driver. Switching manually is

prone to error and is not an efficient way. In order to solve such problem, Sunix has developed a special technique call

AHDC/CS for RS-485 transmission to provide a precise data direction control automatically. Unlike ordinary RS-485

direction control, AHDC/CS also makes its best to avoid possible collisions which provides even more reliable

communication.

AHDC/CS works seamlessly with transmit and receive unit of Matrix UART Controller and control the direction on-the-fly,

hence it won’t incur any additional overhead and latency.

Automatic RS-422/RS-485 Detection and Switching

SUNIX developed a unique technology “Auto Detect and Switching RS-422 / 485”, which can automatically detect the state

of RS-422 full duplex or RS-485 half duplex and control the data transmitting and receiving wires at the same port

without any jumper settings. This design gives users the convenience to change the communication mode setting without

any system shut downs.

Built-in Surge protection and Isolation (Option for SI version)

Surges are high amplitude electrical pulses lasting only several millionths of a second in duration. They can be caused by

heavy-duty equipment, power lines, short circuits, or large motors. A surge suppressor has the ability to effectively

absorb the high energy in an extremely short period of time, preventing the connected devices from damage. Sunix Martix

Multi-port Serial Card (SI version) has built-in 400W surge protection on all of the signals that meets IEC61000-4-5

standards.

Isolation eliminates the direct galvanic connection between digital system and output drivers/receivers. Optocouplers is

used for data isolation and magnetic transformers for power source isolation.

Galvanic isolation removes the ground-loop currents from data lines; hence, the impressed noise voltage that affects the

signal also is eliminated. Common-mode noise can be removed completely and many forms of radiated noise can be

reduced to negligible limits using this technique.

It is highly recommended for use in high-noise environments.
