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 COMSelector (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.

2.2 COM Port Mapping and Board ID
The Board ID and COM port mapping are the same, which is set by the S1
DIP switch. The S1 DIP switch has different functions under different OS.
For DOS users, the S1 DIP switch acts as Board ID. When there are two or
more multi-port serial cards in a single system, it is difficult to identify individual
card number. For easier identification, the VXC series card includes a Board ID
function.
For Windows users, the S1 DIP switch acts as COM port number selector
and the COM port number is depending on the Board ID. If the Board ID is 0,
then the driver finds a valid number for each port. If the Board ID is not 0, then
the driver uses the “Board ID” to be the first COM port number and uses the
“Board ID +1” to be the next COM port number and so on.
Note: It’s recommended to select a unique COM port number (Board
ID) by users. This helps users to identify and fix these cards and ports
in a system without confuses.
Note: The port will not work if the COM port number is conflicted under
Windows or Linux system. In that case, users should try other COM port
numbers.
number selector.
Usually, the COM1 and COM2 are reserved by systems. And it’s
recommended to reserve the COM3 and COM4 if you will have othe
Plug&Play serial ports in the future. This prevents confliction.
For Linux users, it’s the same as Windows users but for TTY device
The configuration examples are as follows.
