If there is only one clock controller card in the system, set to OFF. If there are two clock

controller cards, determine the total cable length between the J3 connectors (no single cable

can exceed 25 ft.) and set these two switch positions for this cable length, as shown above. The

maximum total (combined) length is 50 ft. Set the switches on both cards to the same settings.

**

Set to ON for clock controller 0. Set to OFF for clock controller 1.

Note: FNF based-systems the total clock path length is equal to the length of the NTRC49 cable

used to connect between the two clock controller cards.
