Basler racer Camera Link 1
1 Camera Link Implementation
1.1 Overview
The Basler racer Camera Link camera transmits Camera Link data in a fashion similar to devices
that use National Semiconductor DS90CR287 transmitters. For Camera Link receivers on your
frame grabber, we recommend that you use the National Semiconductor DS90CR288A or an
equivalent.
The camera receives the RS-644 camera control input signals and the serial communication input
signal defined in the Camera Link specification in a fashion similar to devices that use National
Semiconductor DS90LV048A differential line receivers. The serial communication output signal
defined in the specification is transmitted in a fashion similar to devices that use a DS90LV047A
differential line transmitter.
Detailed data sheets for the National Semiconductor components are available at the National
Semiconductor web site (www.national.com). The data sheets contain all of the information,
including application notes, that you need to implement Camera Link.
All camera models have two 26-pin SDR connectors with 0.03" pin spacing as specified in the
Camera Link standard.
Table 2 on page 3 and Table 3 on page 4 show the pin assignments for the SDR connectors.
The "SDR" (Shrunk Delta Ribbon) designation is the naming used by the 3M
company. Other companies use different names for this type of connector. For
example, Honda uses "HDR" as the connector name.

2 Basler racer Camera Link
All camera models implement the "base", "medium", and "full" configurations as defined in the
Camera Link standard. Individual differential line transmitter circuits support the respective Camera
Link configurations: Transmitter X supports the base configuration, transmitter Y partly supports the
medium configuration and partly the full configuration, and transmitter Z supports full configuration.
The determination of whether a camera will operate in the base, medium, or full configuration
depends on the camera’s current tap geometry setting as shown Table 1.
1.2 SDR Connector Pin Assignments and
Numbering
Two 26-pin, 0.03” pin spacing, Shrunk Delta Ribbon (SDR) female connectors are used on the
camera. The pin assignments and pin numbering for the base connector are as shown in Table 2
and for the medium/full connector are as shown in Table 3 on page 4.

1.3 Electrical Implementation
The schematics in Fig. 2 through Fig. 6 on the following pages illustrate the basics of the racer
Camera Link electrical implementation. The basic difference between the schematics is the number
of transmitters used and the port assignments for each transmitter.
Fig. 2 on page 6 illustrates the implementation when a camera is set for the 1X or 1X2 tap geometry,
which will cause it to operate in the base Camera Link configuration. In this situation, only the X
transmitter is used.
Fig. 3 on page 7 illustrates the implementation when a camera is set for the 1X4 tap geometry,
which will cause it to operate in the medium Camera Link configuration. In this situation, the X and
Y transmitters are used.
Fig. 4 on page 8 illustrates the implementation when a camera is set for the 1X8 geometry, which
will cause it to operate in the full Camera Link configuration. In this situation, the X, Y, and Z
transmitters are used. This configuration is commonly referred to as an "octo" configuration
because eight sets of Camera Link ports are mapped to the transmitters.
Fig. 5 on page 9 illustrates the implementation when a camera is set for the 1X10 geometry, which
will cause it to operate in the full Camera Link configuration. In this situation, the X, Y, and Z
transmitters are used. This configuration is commonly referred to as a "deca" configuration because
ten sets of Camera Link ports are mapped to the transmitters.

1.4 Camera Link Input Signals
The input signals that the camera can accept via the Camera Link interface include a Serial to
Camera signal and an External Line Start Trigger signal as described below.
1.4.1 Serial to Camera
The Serial To Camera (SerTC) input signal is an RS-644 LVDS signal as specified in the Camera
Link standard. The signal is input to the camera on pins 7 and 20 of the base SDR connector as
specified in the standard and as shown in Fig. 2 on page 6. The camera is equipped for RS-644
serial communication via a serial port integrated into the frame grabber as specified in the Camera
Link standard.
The RS-644 serial connection in the Camera Link interface is used to issue commands to the
camera that change parameter values. The serial link can also be used to query the camera about
its current setup.
1.4.2 External Line Start Trigger (ExLSTrig)
The camera can be set to accept an External Line Start Trigger (ExLSTrig) input signal to control
exposure and readout of the camera’s sensor. When the ExLSTrig signal is applied to the camera
via the Camera Link interface, it is an LVDS signal as specified for RS-644. By default, the camera
will accept an ExLSTrig signal on the CC1 input in the Camera Link interface (pins 9 and 22 of the
MDR connector) as specified in the Camera Link standard. The camera can also be configured to
accept the ExLSTrig signal on CC2, CC3 or CC4.
When the camera is under the control of an ExLSTrig signal, it can be set to function in two
exposure time control modes: timed or trigger width. ExLSTrig can be a periodic or non-periodic
function. The frequency of the ExLSTrig signal determines the camera’s line rate in these modes.
Note that ExLSTrig is edge sensitive and therefore must toggle. The minimum high time for the
ExLSTrig signal is 1 µs and the minimum low time is also 1 µs.
The ExLSTrig signal is typically supplied to the camera by the frame grabber board.
For details about using a line start trigger with racer cameras, refer to the Basler racer Camera Link
User’s Manual (001185xx000).

1.5 Camera Link Output Signals
1.5.1 Serial to Frame Grabber
The Serial To Camera (SerTFG) input signal is an RS-644 LVDS signal as specified in the Camera
Link standard. The signal is output from the camera on pins 8 and 21 of the base SDR connector
as specified in the standard and as shown in Fig. 2 on page 6. The camera is equipped for RS-644
serial communication via a serial port integrated into the frame grabber as specified in the Camera
Link standard.
The RS-644 serial connection in the Camera Link interface is used to issue commands to the
camera that change parameter values. The serial link can also be used to query the camera about
its current setup.
1.5.2 Pixel Clock
The pixel clock is used to time the sampling and transmission of pixel data. The frequency of the
pixel clock (pixel clock speed) is selectable.
For more detailed information about the pixel clock speed, see Section 2 on page 25.
The pixel clock is assigned as defined in the Camera Link standard to the strobe ports (TxClk pins)
of the following transmitter circuits:
transmitter circuit X as shown in Table 2 and in Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6.
transmitter circuit Y as shown in Table 3 and in Fig. 3, Fig. 4, Fig. 5, and Fig. 6.
transmitter circuit Z as shown in Table 3 and in Fig. 4, Fig. 5, and Fig. 6.
1.5.3 Line Valid Bit
As shown for example in Fig. 10 on page 31, the line valid bit indicates that a valid line is being
transmitted. Pixel data is only valid when the line valid bit and the data valid bit are both high.
(In those cases where the data valid bit is not available (see Section 1.5.4 on page 13), pixel data
is valid when the line valid bit is high.)
The line valid bit is assigned as defined in the Camera Link standard to the line valid ports of the
following transmitter circuits:
transmitter circuit X as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6.
transmitter circuit Y as shown in Fig. 3, Fig. 4, Fig. 5, and Fig. 6.
transmitter circuit Z as shown in Fig. 4, Fig. 5, and Fig. 6.

Basler racer Camera Link 13
1.5.4 Data Valid Bit
As shown for example in Fig. 10 on page 31, the data valid bit indicates that valid pixel data is being
transmitted. Pixel data is only valid when the line valid bit and the data valid bit are both high.
(In those cases where the data valid bit is not available (see below), data is valid when the line valid
bit is high.)
The data valid bit is assigned as defined in the Camera Link standard to the data valid ports of the
following transmitter circuits:
transmitter circuit X as shown in Fig. 2, Fig. 3, and Fig. 4.
transmitter circuit Y as shown in Fig. 3 and Fig. 4.
transmitter circuit Z as shown in Fig. 4.
1.5.5 CL Spare Bit
As shown in Fig. 2 on page 6 and in the tables in Section 1.5.6 on page 13, the Camera Link
standard defines a CL spare bit. The camera can be configured to apply one of the following output
signals to the CL Spare bit:
Line Trigger Wait
Exposure Active
1.5.6 Pixel Data Bits
Pixel data bits are transmitted via output ports on transmitter circuits X, Y, and Z. The assignment
of pixel data bits to output ports varies depending on the camera’s current Camera Link Tap
Geometry setting and also on the bit depth of the pixels being transmitted (bit depth is determined
by the current Pixel Format setting).
The bit to port assignments for each available combination of tap geometry and pixel format settings
are shown in the tables on the following pages.
The data valid bit will not be available:
If the camera is set to operate in the 1X8 tap geometry at 10 bit pixel depth.
If the camera is set to operate in the 1X10 tap geometry.
The CL Spare bit will not be available
If the camera is set to operate with 1X8 tap geometry at 10 bit pixel depth.
If the camera is set to operate with 1X10 tap geometry.
