Pin with pull-up resistor to load cable.
An = side driving internal IC;
Bn = side driving external cable (bidirectional);
Cn = side receiving control signals from external cable;
H = HIGH voltage level;
L = LOW voltage level;
OC = Open Collector;
X = don’t care (control signals in);
Yn = side driving external cable (unidirectional);
Z = high impedance (high-Z) or 3-state;
TP = totem pole output;
RP = resistive pull-up: 1.4 k (nominal) on B/Y/C cable side and V
signal on the A side, that particular B/Y side resistor is switched off to stop current drain from V
When DIR = L and OEA = H, the output signal is isolated from the input signal. Signals B1 to B8 maintain a resistive pull-up of 1.4 k on
the input for this mode.
