4.5.3 Data Cables (Accessories)
For transmission of the data signals between the
RTC6 PCIe Board (or the XY2-100 Converter
(Accessory)) and the scan system, appropriate cables
are obtainable from SCANLAB. Data cables are
generally not included in the scope of delivery.
For SCANLAB scan systems equipped with an SL2-100
interface (9-pin female D-SUB connector), data cables
are available for electrical transmission, for optical
transmission (only upon request) also optical fiber
cables
(1)
.
For SCANLAB scan systems equipped with a XY2-100
interface (25-pin female D-SUB connector) solely
electrical cables are obtainable.
Scan systems equipped with an optical interface
(XY2-100-O) cannot be controlled by the
RTC6 PCIe Boards.
With self-constructions, SCANLAB recommends the
following design for electrical data transmission:
• For SL2-100 protocol-compliant data
transmission, see Figure 15, the cable should be
fitted with 9-pin male D-SUB connectors at both
ends. The two channels DATA IN± and
DATA OUT± must consist of twisted cable pairs
and be cross-connected at both D-SUB
connectors (for example, so that the DATA OUT
signal of the RTC6 PCIe Board flows to the
DATA IN input of the scan system). The cable
length should not exceed 25 m. SCANLAB
recommends a cable impedance of 110 ,
independent from the cable length.
• For XY2-100-compliant data transmission, see
Figure 16, the cable must have identical 25-pin
(male) D-SUB connectors at both ends. The five
(or six) channels SYNC±, CHAN1±, CHAN2±,
STATUS± (and STATUS1±) and CLOCK± must
consist of twisted cable pairs. Together with an
XY2-100 Converter (Accessory) with standard
jumper configuration, the data cable should not
be longer than 20 m. If a longer data cable is
needed, then the solder jumper setting of the
XY2-100 Converter (Accessory) need to be
reconfigured.
• For XY2-100-compliant data transmission, the
controller end of the data cable must be fitted
with a ferrite identical in construction to
Würth WE 74271132.
Independently from the data transmission protocol,
the following applies in addition:
• The data cable must have coaxial copper braided
shielding.
• The D-SUB connectors must have fully shielded
metal housings.
• The electrical connection of the cable’s braided
shielding to the D-SUB housing must not be
implemented as a wire. Instead, the cable’s
braided shielding should be coaxially connected
to the D-SUB housing by shielded clamps.
Some scan heads have only a single connector to
provide both the operating voltage and the data
signals. For these scan heads, SCANLAB recommends
implementing a cabling solution which uses a
separate cable for data. The cable should have the
properties as already described, see above.
(1) The optical fiber cables, too, are attached by 9-pin
D-SUB connectors. Optical conversion
(Polymer Optical Fiber conversion) for optical data
transmission takes place inside the D-SUB connectors.
The operating voltage for Polymer Optical Fiber
conversion is supplied at the RTC6 PCIe Board
scan head connectors and the digital interface of the
scan system.
