4.5 Interfaces to Scan System
4.5.1 Scan Head Connectors and
Transfer Protocol
The first scan head connector SCANHEAD and the
optionally activated second scan head connector
2. SCANHEAD are available for digitally controlling
scan systems, see Figure 10.
At those connectors, scan-system control values are
transmitted and scan-system status signals received.
Each scan head connector can transmit data for up to
two axes. Consult your scan system’s operating
manual to determine which status signals are
generated by your scan system and how they can be
applied for monitoring purposes.
Data transfer between the RTC6 PCIe Board and the
scan system is in accordance with the
SL2-100 protocol. The XY2-100 Converter
(Accessory) is available for converting the signals (for
data transmission according to the XY2-100
protocol).
If neither the Option “Second Scan Head Control” nor
the Option “3D” is enabled, only the first scan head
connector outputs signals for an xy scan system.
If the Option “Second Scan Head Control” is enabled,
two xy scan systems can be simultaneously
controlled by one RTC6 PCIe Board.
If the Option “3D” is enabled, then a 3-axis
scan system can be controlled by the two scan head
connectors (if the first scan head connector has been
assigned a 3D correction table). Signals can then be
outputted by the first scan head connector to an
xy scan head – and by both channels of the second
scan head connector to the third axis (z axis).
If both options (Option “Second Scan Head Control”
and Option “3D”) are enabled, the assignment of the
correction tables determines which signals (xy or z)
are to be outputted by which connector, see also
Section ”2D and 3D Correction Files”, page 174.
If several RTC6 PCIe Boards with enabled Option
“3D” are installed in a PC, then that many 3-axis
systems can be simultaneously controlled.
