2010-9-16 · by 0.10 to 6.0 Vdc line A with respect to line B. A logical zero state (space) is denoted by -0.10 to -6.0 Vdc line A with respect to line B. The DC input impedance of a single BCD time code input is equal to or greater than 5000 ohms. Input reactance, if any, is capacitive. Multiple BCD time code inputs may be connected in parallel.
