Page 10 Installation Instructions: AM-3501 Expansion Subsystem
4.You must remove the termination resistor packs from all I/O boards except
the last board on the expansion cable.
5.There is a 60-pin cable in your product installation kit that has seven
60-pin connectors. Start by plugging the cable into the INTERNAL
(J4)connector on the AM-349 board. Make sure the colored stripe on the
cable aligns with pin-1 on the AM-349’s J4 connector.
6.Starting with the first I/O paddle board, connect the cable to each
successive board attached to the rear panel, leaving any unused cable
connectors hanging loose at the end of the cable. Do not
twist the cable!
The colored stripe on the cable must align with pin-1 on each of the I/O
paddle board connectors.
7.For additional information on termination and cabling, refer to the
corresponding product installation guide for the various I/O board types.
7.0SOFTWARE CONSIDERATIONS
Information on creating drivers for SCSI peripheral devices supported by the AM-3501
subsystem is contained in the installation guide for each peripheral device. The
information includes termination, addressing, creating software drivers, and adding the
devices to the system initialization command file.
There are three special "B-channel" serial I/O software drivers used for the subsystem:
1. AM355B.IDV is the driver that supports AM-355 boards.
2. AM358B.IDV is the driver that supports AM-358 boards.
3. AM359B.IDV is the driver that supports AM-359 boards.
Each of the above software drivers is unique, and must be used to access the ports on
the corresponding SIO expansion board. When mixing different board types on the
same SIO bus be sure to calculate the correct board select address and octal port
numbering based upon the operational parameters of each
preceeding
SIO paddle
board on the bus. Refer to the installation instructions for each type of SIO board for
more detailed information.
