ST43401N/ND and ST43402ND Reference Manual, Rev. C
Table 3 lists the parts needed to construct unshielded I/O cables. Table 4 lists
part numbers and lengths of synchronized spindle cables. Table 5 provides
part numbers of external terminators and resistor-pak terminators.
ST43402ND (dual port) drives have both I/O connectors (one for Port A and
the other for Port B) located on the I/O board. You must use an adapter (part
number 70935801) to terminate each I/O cable following the last drive in the
daisy chain.
ST43401N/ND (single-ended) drives are shipped with resistor-pak termina-
tors installed on the control board. Each end of the daisy-chain I/O cable must
be terminated. If the resistor-pak terminators are in place on the drive, external
terminators are not needed. Single-ended terminators and differential termi-
nators have different part numbers and electrical characteristics (they cannot
be interchanged).
