2.10.1 Input / Output Mapping
The camera has 2 external inputs (1 TTL input and 1 opto-coupled input) and 2
external outputs wired to the 12 pin HIROSE connector, located on the back of the
camera. In addition to these inputs and outputs, Camera Link inputs (CC1 and CC2)
are also available. The user can map CC1 and CC2 or either external input to the
Trigger input. The user can map the camera outputs to: Trigger, Pulse Generator,
Strobe One, or Strobe Two. For each mapped signal active “High”, active “Low”,
can be selected. All possible mapping options for the camera inputs and outputs are
shown in Table 2.8a and Table 20 respectively.

2.10.2 Electrical Connectivity
The Cheetah has two external inputs: IN 1 and IN 2. Input “IN 1” is optically
isolated, while Input “IN 2” accepts Low Voltage TTL (LVTTL). Cheetah provides
two general purpose outputs. Output “OUT 1” is a 5v TTL (5.0 Volts) compatible
signal and Output “OUT 2” is opto-isolated. Figure 21 and 22 shows the external
input electrical connections. Figure 23 and 24 shows the external output electrical
connections
