Opto-isolated Input
Input signals IN1 and IN1 RTN are optically isolated. The voltage difference between the two
must be positive between 3.3 V and 24 V. The minimum input current is 3.3 mA.
Input IN1 pin numbers may vary for different camera models (see
).

TTL/LVTTL Input
Input signals IN2 and IN2 RTN provide interfaces to a TTL or LVTTL input signal. The signal level
(voltage difference between the inputs IN2 and IN2 RTN)
must be
LVTTL (3.3 V) or TTL (5.0 V).
The total maximum input current
must not
exceed 2.0 mA.
Input IN2 pin numbers may vary for different camera models (see
Figure 14
: TTL input electrical schematic (simplified)
TTL Output
TTL output provides interface to a TTL compatible output signal. The signal level (voltage
difference between the outputs OUT and OUT RTN) is TTL (5.0 V). The maximum output
current
must not
exceed 8.0 mA.
Output name (OUT1 or OUT2) and a pin number may vary (see
).
