2.2.4 Electrical Connectivity
Cheetah cameras have two external inputs: IN 1 and IN 2. Input IN1 is optically isolated
while input IN2 accepts low voltage TTL (LVTTL). Cheetah cameras provide two general-
purpose outputs. Output OUT1 is a 5v TTL (5.0 Volts) compatible signal and output OUT2
is opto-isolated. The following graphics show the external input electrical connections and
the external output electrical connections:
A. Input IN 1- Opto-Isolated
Input signals IN1 and IN1 Rtn are optically isolated, and the voltage difference between
the two must be positive between 3.3 and 24 volts.
