7.7 Trigger and Strobe Signals for GigE Cameras
7.7.3 Single-ended Outputs
ISO_OUT0 and ISO_OUT1 are single-ended isolated outputs.
ISO_OUT0 and ISO_OUT1 have different output circuits: ISO_OUT1 doesn’t have
a pullup resistor and can be used as additional Strobe out (by adding Pull up) or
as controllable switch. Maximal ratings that must not be exceeded: voltage: 30
V, current: 0.5 A, power: 0.5 W.
Fig. 7.7 shows the connection from the ISO_OUT0 output to a TTL logic device. PTC is a current
limiting device.
