5 ART Tracking Controllers
the DTrack2 frontend software on the remote PC. Please refer to chapter 8 on page 121
for more details.

If the ART controller is not connected via an ethernet cable or no DHCP
server is running, it will use its fall-back IP address (IP 192.168.0.1,
subnet mask 255.255.255.0)
You may configure a static IP address the following ways:
• using DTrack2 (refer to chapter 8.2.2 on page 125)
• without the DTrack2 frontend (refer to chapter 8.2.4 on page 127)
Z
Please note that these settings are not part of your personal configura-
tion. Changes of the IP address will affect all users of your controller!
Your controller may become unreachable with wrong IP settings! Refer
to chapter 8.2.4 on page 127).
5.1.5 External synchronization
The ART Controller can be synchronized with an external source. On the back of the
controller there is a BNC plug ’ExtIn’ which serves as input for the external synchroniza-
tion signal. The sync signal may be of type TTL (5V) or video. Using TTL you can select
between rising and falling edge trigger and triggering on both edges (see also chapter
8.5.2 on page 151).
Typically, external synchronization has to be used when other systems inside the tracking
system are also using infrared signals for controlling their equipment (e.g. if IR-controlled
shutter glasses are used). The goal is to reduce or eliminate interference. The ART track-
ing system follows the external synchronization signal and chooses time slots when it is
safe to emit infrared radiation without causing interference. The effect is, for example, that
active shutter glasses are not flickering but offer a stable picture for the user.
Z
The external sync input is not internally terminated.
When synchronizing with a video input, a tee connector with an exter-
nal 75 Ω terminating resistor should be used if the signal line ends at
the controller.
When using a TTL-signal you should not use a terminating resistor.
However, you should use a shielded cable for the synchronization with
a TTL-signal.
