Using the Inputs with LVTTL
A camera input line can accept a Low Voltage TTL signal when the signal is input into the camera
as shown in Fig. 19.
The following voltage requirements apply to the camera’s I/O input (pin 2 of the 12-pin connector):
When LVTTL signals are applied to an input, the 120 ohm termination resistor on that input must
be disabled. The input will not react to LVTTL signals if the resistor is enabled.
For the camera’s I/O circuitry to operate properly, you must supply a ground as shown Fig. 19.

Voltage Significance
+0 to + 5.0 VDC Recommended operating voltage.
+0 to +0.8 VDC The voltage indicates a logical 0.
> +0.8 to +2.0 VDC Region where the transition threshold occurs; the logical state is not defined in this
region.
> +2.0 VDC The voltage indicates a logical 1.
+6.0 VDC Absolute maximum; the camera can be damaged when the absolute maximum is
exceeded.
