ground connection is at the host site, make sure none of the power
supplies is grounded. This method prevents ground loop problems
due to offset voltages appearing between multiple ground points.
racks, the + 5 VDC logic connection is made by the supply when it is
screwed to the rack. In this case, the only connection required is the
120 VAC (220 VAC or 10–28 VDC depending on supply type)
connection to the PBSA (or PBSB or PBSC) supply.

When using a multiple-output supply, make sure that the 5 VDC
RETURN line is separate from the 15-volt COMMON line.
Otherwise, the analog modules will not be isolated.

cable, keep in mind that the cable is a high-speed data-transmission
line. To reduce reflections, make sure the line is terminated properly
at both ends and that all stubs are less than three inches long.
each brain board acts as a repeater, allowing up to 5,000 feet
between units. Since a power failure at any unit breaks the
communications link, battery backup is recommended. Note that
you cannot mix units operating in repeat mode and units operating
in multidrop mode on the same network.
