7.6 Input and Output Lines
7.6.1 Input Lines
The camera is equipped with three physical input lines designated as Input Line 1, Input Line 2, and
Input Line 3. The input lines are accessed via the 12-pin connector on the back of the camera. The
inputs are designed to accept RS-422 differential signals, but they can also be used with RS-644
low voltage differential signals or low voltage TTL signals.
7.6.1.1 Electrical Characteristics
Using the Inputs with RS-422
As shown in Fig. 17 and in the I/O schematic at the beginning of this section, each input is designed
to receive an RS-422 signal. For the camera’s I/O circuitry to operate properly, you must supply a
ground as shown in Fig. 17.
