("X" means the function selection can be made with jumpers on that connector;
("Y" means the signal is available to host through that connector.)
Notes for Table 4 [ ]:
[a] Use either J6 or J1-Aux, but not both.
[b] I/O connector J1 plugs directly into host. No jumper can be installed on J1. The host supplies the logic
state of these function signals causing the selection of these functions. See pinout Table 13d and 13e.
[c] The host can drive a remotely located Drive Activity LED using signal.
[d] Use either J1 or J6, but not both.
[e] The drive reads the ID (asserted low) from J1-Auxiliary pins 1, 3, 5 and 7 for 250 ms after power-on or
drive reset. Jumper plugs can be used on J1-Auxiliary pins 1-2, 3-4, 5-6 and 7-8 to set drive ID if desired,
but usually a connector/cable is plugged to J1-Auxiliary to run these signals to the host for remote ID
selection.
[f] The host selects drive ID through J1.
