2.2 Electrical Connectivity
A. Inputs IN1
The external inputs in Cheetah HD-SDI cameras are connected directly to the
camera hardware as shown in the following figures. The in
put signals “Signal”
and “Return” are
used to connect to an external input on the outside source. For
IN1,
the signal level (voltage difference between the inputs “Signal” and
“Return”) MUST
NOT exceed 1.2Vpp.
Figure 4: IN1, Tri-Level Sync electrical input connection.
B. Outputs OUT1
The OUT1 external output in Cheetah HD-SDI camera is directly connected to the
camera hardware and is a TTL (5.0 Volts) compatible signal. The maximum output
current MUST NOT exceed 8 mA. The following figure shows the OUT1 output
external electrical connection.
Figure 5: OUT1 electrical connection.
C. Outputs OUT2
Output OUT2 is an optically isolated switch. There is no pull-up voltage on either
contact. The voltage across OUT2 Contact 1 and OUT2 Contact 2
must not
exceed
25 volts and the current through the switch
must not
exceed 50 mA.
