Wiring diagram
Connecting an isolated output to a TTL receiver using the receiver's V
CC
supply
See also:
in the hardware manual for I/O connectors pin assignments.
1.
Connect OUT+ to TTL V
CC
. Nominally, V
CC
should be 3.3 V or 5 V.
2.
Connect OUT- to the TTL input.
3.
Pull-down OUT- with a resistor (R) of 180 ohm 1/8 W (or another resistor value that suits the
circuit requirements).
TIP
As good practice, it is recommended to shield the whole set of wires, using a
shielded cable. Shielding improve EMI protection against external
interferences (immunity) and avoid unwanted EM emissions. The shield
should be connected to the devices (PC, cameras, and systems components)
chassis and should be separated from the digital GND line.
Static levels compatibility
The following tables show that the voltage levels are well compatible and that they remains
acceptable voltage margins for both TTL and LVTTL applications.
