Isolated input block diagram
The inputs can be connected directly to the system for voltages up to 24 V DC. An
external resistor is not necessary.
Goldeye G isolated input delay and minimum pulse width
The minimum pulse width for all Goldeye G cameras is:
Test conditions
The input signal was driven with 3.3 V (LVTTL) and no external additional series
resistor was used.
Output signals
Output signals can be assigned to a variety of internal camera signals via software.
They can be configured to active high or active low. The internal camera signals are
listed in Table 39 on page 71 .
