dbx DriveRack 260 User Manual page 66

When connecting Zone Controllers, in series, the following cable length restrictions apply:
• If using a single ZC, the ZC may be connected directly to the DriveRack 260. The maximum
cable length for a single ZC connected to the DriveRack 260 cannot exceed 1000 feet.
• As shown in Diagram A, any (3) Zone Controllers may be wired in series as long as the
total cable length does not exceed 600 feet.
• Any (6) Zone Controllers may be wired in series as long as the total cable length does not
exceed 300 feet. Refer to Diagram B.
• Cable runs of up to 1,000 feet may be achieved using "Home Run" wiring. An example of
this is shown in Diagram C. A dbx Zone Controller Break Out Box (dbx ZC-BOB) is used
to parallel several cable runs (up to six).
Note: The preceding cable lengths were achieved using Cat5 Enhanced cable exhibiting a
maximum D.C. resistance of 29 Ohms per 1,000 feet. Daisy chaining ZCs off the ZC-BOB is
not recommended or supported.
