6 Hardware Interface
6.5.4 Differential RS-422 Inputs (G2 models)
ISO_INC0 and ISO_INC1 are isolated differential RS-422 inputs (see also Fig. 6.3). They are
connected to a Maxim MAX3098 RS-422 receiver device. Please consult the data sheet of the
MAX3098 for connection details.
Don’t connect single-ended signals to the differential inputs ISO_INC0 and
ISO_INC1 (see also Fig. 6.11).

6.5.5 Master / Slave Camera Connection
The trigger input of one Photonfocus G2 camera can easily connected to the strobe output of
another Photonfocus G2 camera as shown in Fig. 6.12. This results in a master/slave mode
where the slave camera operates synchronously to the master camera.
