I/O Connector
A 12-pin Hirose type connector on the back of the camera provides all external input/output
signals supplied to the camera. The male Hirose connector is a miniature locking receptacle
#HR10A-10R-12PB(71).

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 5 V TTL compatible signal and output OUT2 is opto-
isolated. The following graphics show the external input electrical connections and the
external output electrical connections.
