Kurzweil HUB7, Manual, Page: 11 / 56

Connecting Your RSP8
1-5
Aftermarket Cables
If the original cable becomes damaged or you would like to use a
different length cable, you can buy replacements from sources
listed on the www.kurzweilmusicsystems.com web site.
The required cable characteristics are:
A. MiniDin-8 male plug at each end
B. All 8 pins wired
C. “Straight through” or “one-to-one” wiring, NOT “cross-
over” wiring
D. Overall braid and foil shield, wired to the plug's shell at
each end
E. #24 gauge wires for length up to 16 meters (52 feet)
#26 gauge wires for length up to 10 meters (33 feet)
#28 gauge wires for length up to 6.5 meters (21 feet)
F. The 8 wires must be arranged as 4 twisted pairs paired as
follows:
Pins 1 and 8 or pins 1 and 2
Pins 2 and 7 or pins 7 and 8
Pins 3 and 4
Pins 5 and 6
Note: Apple Macintosh “serial cables” will NOT work because they
violate requirement C above (they are “crossover wired”).
The wire gauge and length limits listed above are very important
to ensure that adequate power is delivered to your RSP8. If in
doubt, refer to the Diagnostics section of this manual for a
voltage test you can run. To go longer than 16 meters – up to 300
meters – you will need to use a HUB7; see the HUB7 section for
details.
