Camera Interface Details

Mode 1: Continuous mode (Full resolution)

• Matrox Pulsar is SLAVE in this mode, in other words the camera sends the RS-422 (10-bit)

Video, RS-422 HSYNC, RS-422 VSYNC and RS-422 Pixel clock in continuous mode to Matrox Pulsar.

• The frame scan rate equals 9 fps.

• The camera’s parameters are set using the C4742-95 controller software. The correct

commands for this mode should be set to:

n AMD N (Free run) n SHA F (1280 x 1024 mode) n SMD N (Normal read) n NMD N (Normal exposure)

Mode 2: Continuous mode (Binning)

• Matrox Pulsar is SLAVE in this mode, in other words the camera sends the RS-422 (10-bit)

Video, RS-422 HSYNC, RS-422 VSYNC and RS-422 Pixel clock in continuous mode to the Matrox Pulsar.

• The frame scan rate equals 18 fps.

• The camera’s parameters are set using the C4742-95 controller software. The correct

commands for this mode should be set to:

n AMD N (Free run) n SHA F (1280 x 1024 mode) n SMD S (Binning read) n NMD N (Normal exposure)

Cabling Requirements

PUL-CID-038

Mode 1: Continuous mode (Full resolution)

• PULSAR/DIG/MOD board required for digital data, syncs and control signals in RS-422

format.

• The connections between the PULSAR/DIG/MOD and the 68-pin connector of the camera are

as follows:

PULSAR/DIG/MOD Hamamatsu C4742-95 (PLS/CBL/OPEN connector) (68-pin connector)

Pin name Pin no Pin name Pin no.

CLOCK, INPUT, - 63 ← PIXCLK - 1 CLOCK, INPUT, + 29 ← PIXCLK + 35 HSYNC, INPUT, - 60 ← HVALID - 2 HSYNC, INPUT, + 26 ← HVALID + 36 VSYNC, INPUT, - 59 ← VVALID - 3 VSYNC, INPUT, + 25 ← VVALID + 37 DATA, INPUT, 0 - 54 ← DB0 - 4 DATA, INPUT, 0 + 20 ← DB0 + 38
