1. Introduction

The VXC series multi-port serial card enables user to install additional

communication ports on the PC. It’s the best choice for time-critical and reliably

communications and controls on the industrial environment. For example:

Communicates to PLC, FAB machine, meter, console management of devices,

laboratory instruments and Modem link, etc. In harsh industrial environments,

the onboard surge protection protects the computer and other equipment from

being damaged by high potential voltages.

COM-Selector:

The VXC series cards equip a COM-Selector (dip switch) for the COM port

number selection (automatically or manually). It’s an important and innovative

feature of the VXC cards. It has the following advantages:

• Simplifies the COM port number selection without using configuration utility programs.

• Users specify the COM port number exactly what they want, no matter which PCI slot

is using.

• Automatically select an available COM port number is supported by setting the COM-

Selector (dip switch) to 0 (default).

• Needn’t to install configuration utility for different OS, and needn’t to study operations

of the utility.

• Prevents confusion. Other PnP COM port devices always confusing users by using a

dynamic COM port number.

• Replacing an existing card is very easy, just setting the COM-Selector (dip switches)

to the same.

• It’s great for mass system installation, just setting the COM-Selector (dip switches) to

use the same COM port number in systems.

Up To 128KB Software FIFO:

The VXC card driver for Windows features a maximums 128KB software

FIFO for each port (default is 4KB). It’s practical for large file transmission.

Self-Tuner:

The RS-485 ports of VXC cards equip a “Self-Tuner” chip, which controls the

sending/receiving direction, baud rate and data format automatically and

reduces the software loading for such controls.
