SETUP
M300 setup information for board entries, acquisition event entries and buffer.
GENERALSETTINGS
There are several aspects of the board dialogs that are common to most boards.
Address
The address of the board uniquely identifies the board entry. The same applies to the board name.
The M300 will give you a warning if there is an address conflict and the board can’t be added at the
address requested. If this is the case, you must pick a different address.
The board address is derived from the ISA hexadecimal boards. Each ISA board in the PC must have
a unique address, otherwise there will be an address conflict and the boards will not work.
With the added support for PCI cards, QNX 4 serial board type devices (/dev/ser2, /dev/ser3),
Network board type devices, etc, it was necessary to assign a pseudo address to these devices so it
would work in the M300 methodology.

Port
Contains the name of the communication serial port. For /dev/ser1 the pseudo address is 0xFF01.
For /dev/ser2 the pseudo address is 0xFF02 and so forth.
The name of the serial ports must be configured to /dev/ser1, /dev/ser2, etc. This is so that the M300
can do pattern matching on the port name and determine if the port is a valid serial port.
When you type the port number and hit the enter key, the dialog will fill in the board address.
For most boards, the user must use the real ISA address from the board or serial port as the source.
There a special address of 0xFFFF that can be selected when using the serial port type devices. The
correct pseudo address will be used.
Make sure no other applications outside the M300 are using the serial ports that are being used by
the M300. Depending on what those applications are doing this might not work with the M300.
State
Controls the item state. Setting the state (toggle button becomes purple) enables the item, while
disabling the state disables the item.
