Notes:
(1) → Output from device; ← Input to device.
(2) Use shielded cable with twisted pairs, e.g. UL2919 28AWG. Twisted pairing must be
1-26, 2-27, 3-28, etc.
(3) M34 connector shells must be metallised. Connect braid to connector shells to make a
360° connection.
(4) Standard cable length is 2.05m ± 0.05m.
(6) Resistors are 1% tolerance.
(7) Applies to cable version 2.0 or later.
(5) Ferrite must be fitted to cable 31mm ± 3mm from rear of D50 SCSI-2 backshell.
