6.2Installing Serial I/O Boards

All serial I/O paddle cards have factory installed mounting brackets. The following

instructions explain how to install the paddle cards in the AM-3501 subsystem:

1.The serial boards attach directly inside rear panel and are held in place

with three screws. To install a serial I/O board, you must first remove the

filler panel covering the slot where you wish to install the board.

2.The first board should be installed in the 2nd from left or "A" slot, as shown

3.If mixing different types of SIO boards, you should first group them

together by type, then set the addressing jumpers in accordance with the

applicable set of installation instructions.

Remember, the three types of I/O boards consume different amounts of

addressing space allocated to the I/O expansion bus. Therefore, as a

general rule you should address and install all the I/O boards which

consume the

most

address space first, then install all the I/O boards

which consume the next-most address space, etc.
