Boards Properties

The properties of a board depend on the type of board installed in the I/O Server computer.

Note: The term "Board" is a legacy term from the time when most ports on a computer were provided by additional boards. For example, an Ethernet card. The logical board concept is still useful even though a physical board may not exist (it may be software).

Boards have the following properties:

Board Name

A name for the board. 16 characters maximum. For example Server1_Board1.

If you have more than one board in your I/O Server computer, the name of each board needs to be unique. If you have multiple I/O Servers, the board name need only be unique within each server. For example Server1_Board2

Board Type

The type of board. 16 characters maximum.

If you are using a serial board or your computer's COM port, enter COMx.

Address

The starting address of the Board. For example 0xCC00. 8 characters maximum.

You need to specify the address to match the switch settings on the board when it was installed in your computer. If you are using a serial board or your computer's COM port, enter 0 as the address.

Note: If more than one board is installed in the same computer, use a different memory address for each board.

I/O Port

The I/O port address of the Board. 8 characters maximum.

You need to specify the address to match the switch settings on the board when it was installed in your computer.

Note: If you are using your computer's COM port not enter the port address here. specify the port number in the Ports form.

Interrupt

The interrupt number used by the Board. This is not necessary if using your computer's COM port.

Special Opt

Any special options supported by the board. 32 characters maximum. Please check the Hardware Arrangements Help Topic for your specific I/O Device to see if specific options are necessary.

Comment

Any useful comment. 48 characters maximum.
