[1] For environments where all elements of the bus (cables, device inter-

faces, environmental noise and other parameters) are controlled to

be better than minimally required, it may be possible to extend the

path length and device count.

[2] Extending the device count beyond eight requires specification con-

trol beyond the minimum specified in the ANSI T10/1142D docu-

ment. It is recommended that the devices be uniformly spaced

between terminators with the end devices located as close as possi-

ble to the terminators.

[3] Values specified by data rate shall apply even if a slower data rate is

negotiated.
