Setting DIP switches on WWV Interface Board
The WWV Interface Board (Figure 14) is located directly behind the TCC’s front panel. To gain access to this board,
remove the four screws from the front panel and gently pull the panel away from its box. (It is not necessary to
disconnect the ribbon cable.) Then, remove the plate that covers the board. Adjustments on the WWV Interface
Board consist of setting switches 5 thru 10 of DIP Switch Package SW1 ‘(switches 1 through 4 are unused) as shown
in Figures 15 and 16. -
