Electrical Connectivity
The Cheetah camera has two external inputs, INPUT1 and INPUT2. INPUT1 is optically isolated
while INPUT2 accepts low voltage TTL (LVTTL). The camera provides two general-purpose
outputs. Output OUT1 is a 5 V TTL compatible signal and output OUT2 is opto-isolated. The
following figures show the external input and output electrical connections.
Opto-Isolated Input
Input signals INPUT1 and INPUT1 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.
TTL/LVTTL Input
Input signals INPUT2 and INPUT2 RTN provide interfaces to a TTL or LVTTL input signal. The signal
level (voltage difference between the inputs INPUT2 and INPUT2 RTN)
must be
LVTTL (3.3 V) or
TTL (5.0 V). The total maximum input current
must not
exceed 2.0 mA.
TTL Output
TTL output provides interface to a TTL compatible output signal. The signal level (voltage
difference between the outputs OUT1 and OUT1 RTN) is TTL (5.0 V). The maximum output
current
must not
exceed 8.0 mA.
