For Time of Day Only Synchronization
(timers operate independently) - use
the remote control to set the clocks in
“RS1” serial time code mode and use a
straight thru patch cable.
For Time of Day & Downstream Timer
Synchronization - use the remote control
to set the clocks in “RS2” serial time code
mode and use a crossover patch cable.
Note that all clocks downstream from the
crossover cable will display Time of Day
from the clock in the chain before the
first crossover cable.
A straight thru cable can be installed later
down stream if flow thru of timer data is
no longer preferred.
Timers can still be forced to local control
by use of the “MEM6” button on the
remote control. See pg 7 for more details.

CT-DESK “LEAD CLOCK”

PC KIT
For the first device in the chain
the serial output terminals must
be utilized to drive serial data to
downstream clocks.
For Top of Hour Sync
Connect top of hour closure.
Pulse must arrive +/- 5 seconds
from top of hour.

NOTE:
The serial input
terminal are in parallel
between the two
connectors allowing
data to be looped thru
to down stream clocks.
When looping thru only
upstream data will pass
(i.e. no local timer data
from this clock will flow
downstream.)
NOTE:
The serial output
terminals should be
used only when
it is desired to pass
data from this clock to
downstream clocks
(i.e. local timer data.)
Straight Thru RJ-45 Wiring
Pins 1 thru 8 all connected.
For all cables in the chain that use
straight thru
(standard 568B style) patch cords.
Cross over RJ-45 Wiring
For all cables in the chain that use
cross over
(standard 568B style) patch cords.
