Connect up to 32 serial slav e clocks in Ï dasiy chainÓ
configuration. Use twisted pair 24A WG cable
(preferrably shielded.) The last clock in chain must be
terminated with a 120
Ω
resistor (or use the termination
DIP switch on the CT2002 Lar ge Display.)
Serial daisy chain
connectivty may also
be via CAT-5 cable and
RJ-45 conectors.
Use a standard 568B
ethernet patch cable
(all wires conecting
straight thru pin to pin)
or for custom made
cables observe pinouts
to right.
