includes board number, board type, firmware version number
and unique serial number. Each enclosure in a system contains a base board. These boards are
numbered 1, 5, 9 and 13. Board 1 is the master board with the screen and keypad attached. Each
base board has three slots for communication boards, whose node number increments from the base
board they are installed on. For example, the master board, or node 1, has communication slots with
nodes numbered 2, 3 and 4.
Highlighting a base board and pressing the “Select” key will open a further information screen
showing the I/O plugin cards installed, their location and hardware and software version numbers.

The mainboards and communication boards in an analyzer communicate over a CANBUS network. Each board has a
unique Node number for identification on this network.
