Notes:
(1) → Output from router; ← Input to router.
(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 metal.
Connect braid to connector shells to
make a 360° connection.
(4) Standard cable length is
2.05m ± 0.05m.
(5) Ferrite must be fitted to cable no more
than 25mm from rear of D50 SCSI-2
backshell.
(6) Resistors are 1% tolerance.
(7) See accompanying text for information
about earth loop conditions.
(8) Cable version 2.0.
