5.5 Trigger and Strobe Signals for GigE Cameras

The 12-pol. Hirose power connector contains two external trigger inputs, two strobe outputs

and two differential inputs (G2 models: RS-422, H2 models: HTL). All inputs and outputs are

connected to the Programmable Logic Controller (PLC) (see also Section 5.6) that offers

powerful operations.

The pinout of the power connector is described in Section A.1.

G2 models: ISO_INC0 and ISO_INC1 RS-422 inputs have -10 V to +13 V extended

common mode range.

H2 models: The voltage level for the HTL interface should be given by the user by

means of connecting the encoder power pin (HTL_ENC_PWR) and the ISO_PWR

pin to the same power supply within a range between 10 and 30V. In the same

way, encoder ground (HTL_ENC_GND) and ISO_GND signals should be connected

to the same ground in order to guarantee the good reception of the differential

signals.

ISO_OUT0 and ISO_OUT1 have different output circuits (see also Section 5.5.2).

A suitable trigger breakout cable for the Hirose 12 pol. connector can be ordered

from your Photonfocus dealership.

Simulation with LTSpice is possible, a simulation model can be downloaded from

our web site www.photonfocus.com on the software download page (in Support

section). It is ﬁled under "Third Party Tools".

Don't connect single-ended signals to the differential inputs ISO_INC0 and

ISO_INC1.

Fig. 5.3 shows the schematic of the inputs and outputs for the G2 models and Fig. 5.4 for the

H2 models. All inputs and outputs are isolated. ISO_VCC is an isolated, internally generated

voltage.
