DC Values (prior to printing)

1

2

3 Using as GND reference

4 2.59V DC

5 3.3V DC

6 3.3V DC

7 0V DC

8 0V DC

9 3.3V DC

10 0V

11 NC

12 0V

13 0V

14 0V

15 0V

16 0V

17 0V

18 0V

19

20

21

During print

1

2 0V

3 Using as GND reference

4 Goes to 3.3v sometimes during print for long (100 to 200ms+ periods)

5 3.3V DC

6 3.3V DC

7 0V DC

8 500ns/3.3v ~every 20us

9 3.3V DC

10 500ns/3.3v

11 NC

12 0V (some ripple)

13 ~84ns/3.3v. Looks like data clk.

14 0V

15 84ns/3.3v Looks like data.

16 0V

17 84ns/3.3v Looks like data.

18 0V

19 Looks like 43v (>30v)

20

21 0V

Pin 4 during print:

1,20 Connected

2,3,7,11,12,14,16,18,21 Connected

5,9 Connected (likely 3.3)

Pin 4 seems up be pulled up to 3.3v on controller. (4.7K pullup)

Hiseq 2000 TDI

Serial number from one module: C10000-515, 661675.

Latest DCAM-API

aslver.exe dump from my cameras:

1: AS-PHX-D48CL-PE1
Grabber HW Version    9.10.00
Grabber SW Version    5.58.24
Library FW Version    9.10.00
Grabber Connection    PCIe x1
Camera Connected    Unknown
Camera Name    C10000-515
Camera S/N    S/N: 661694
Camera Version    INF 2.01-F20-R02

1x PCIe card appears to work. 4x PCIe doesn’t show up on aslver.exe as yet.

Trigger was plugged into SMA port on board, driven by function generator 5V input.

Cameralink cable plugged into top port (furthest from motherboard) on the PCIe cameralink acquisition board.

nope, this little shoulder is the black level / zero value, iirc there was another 3 volts or so before saturation.

top trace is analog output, second trace is the trigger, bottom trace is the clock that cycles samples out after trigger, the short pulses on the trigger line were sample every 32 elements in the scan head or something:

view raw sketch hosted with ❤ by GitHub
the scan head expects a trigger, then a clock, analog values come out on one of the pins during the clocking
the first few elements are from dark elements so you can use them as a reference
sketch reads the 3 full color fields and renders them on a ws2812b strip
these are supposed to be in close contact with paper or something, but it works ok to about 4 inches (can resolve space between fingers)
