2.3.1 10BaseT/100BaseT
For the interconnection of the Inca camera to the host PC
a so-called 10BaseT (for 10Mbs) or 100BaseT (for
100Mbs) connection is used, which is a twisted pair
connection for Ethernet. For this link the PC must be
equipped with an Ethernet Controller.
In order to be able to control multiple Inca 320 cameras a
decent knowledge of how an Ethernet network has to be
configured is required. This manual assumes the reader
has this knowledge.

The Ethernet connector has two LEDs. LED A is the
activity LED and will blink when there is activity. LED B will
be lit when the connection is using 100MBs.
To connect a single Inca camera directly to a PC, a
crossed twisted pair cable is required.
2.3.2
Trigger and Flash
The Inca has an optically isolated trigger input and flash
output.
The trigger input enables the feature to prepare the
capture of an image. If the trigger is enabled by an
application program the capture process will start
immediate when the trigger input is signaled. A rising or a
falling edge on the input can indicate the trigger.
The flash output can control the external flash unit if
required. The active state (high or low) can be
programmed, see the note for side effect.
