4.5.2 Single Ended Selector
By connecting AHi (pin 62) and CLo (pin 14) we can create a 68 channel single ended selector
switch. The collector of this switch is pin 62 (Figure 4-14). Ch1 corresponds to Ch1Hi, Ch2 to Ch2Hi
…Ch10 is Ch10Hi etc.. Using Universal mode, make sure to select both, the appropriate channel
relay as well as the various configuration relays.
Figure 4-14. Single point switching is enabled by connecting A-bus High and C-bus Low.
