Port number:

This is the port ID of each port. Application software will refer to a port

by its port number (ID). Port numbers must be unique; duplicate port

numbers are not allowed. The port number can range from 0 to 255 as

long as it does not overlap with another port. Generally, you should

consider the convenience of programming when specifying the port

number.

TxD buffer size:

This is the transmission (output) buffer allocated in the system for each

port.

RxD buffer size:

This is the receiving (input) buffer allocated in the system for each port.

F5: Group Edit:

This allows you to configure several ports simultaneously as a group.

Press F10 to save the latest configuration and exit the setup program.

Loading the Driver

After setting up the driver, you must load the driver in order to gain access to the serial ports on the

serial board. Run BIN\DP-DRV.EXE at the DOS prompt. The driver will detect your multiport

serial board automatically. You should see messages indicating successful detection of your module,

such as the following:

Smartio/Industio Family DOS driver Version 1.9

Setup driver .

CP-134U series (Bus= x ,Dev=y) : OK!

Device driver setup O.K.

At this point, you can execute applications that support API-232 functions, or start developing

applications using the API-232 library.
