| MISCELLANEOUS TECHNICAL NOTES |
a) The wide differential drives ("WD" models) do
not provide active termination.
b) TERMPWR jumper (J4) is oriented differently on wide differential
drives.
c) Busy LED & fault LED can also be connected in J2 jumper
block.
d) All other jumpers and their function are unidentified. |
