5.10.3 Measured Propagation Delays
The propagation delays reported in this section (see Tab le 13 and Table 14) are likely to be near-
minimum values related to "slow" edges.
The values relate to the specific camera operating conditions listed below and are based on a
camera production lot of 2000 cameras. No inferences can be drawn on propagation delays
resulting from different operating conditions.
The measured propagation delays apply only to the following operating conditions:
Housing temperature: +25 °C.
Load resistance: R
L
= 170 Ω
I/O supply voltage: U
S
= 5 VDC
For the graphical illustration of propagation delays, see Figure 37 and Figure 38.
Propagation Delays for Inputs
Fast Edge Slow Edge
Opto-isolated input 4.5 - 7.5 µs (rising edge) 19 - 28 µs (falling edge)
Direct-coupled GPIO IN < 0.5 µs (falling edge) < 1 µs (rising edge)

Propagation Delays for Outputs
Fast Edge Slow Edge
Opto-isolated output 3 - 6 µs (falling edge) 27 - 38 µs (rising edge)
Direct-coupled GPIO OUT < 0.5 µs (falling edge) < 2.5 µs (rising edge)
