Wiring diagram¶
When using SN75160 and SN75161 integrated circuits, the connections involve at least one
extra pin to control the talk-enable (TE) pin of the IC. The PE pin on the
SN75160 is connected to VCC to maintain a 3-state outputs when TE is high.
Connecting PE to ground will allow the outputs to function in pullup-enable mode
when TE is high.
On the SN75161, the DC pin can be connected to a separate GPIO pin on the Uno/Nano,
or, since ren is always asserted when in controller mode and de-asserted in device mode,
to the GPIO pin used for the REN signal.
