ToUcam Pro II

 

With discontinuing the ToUcam Pro PCVC740 a new camera had to be found to modify. Fortunately the ToUcam Pro II PCVC840 is basically the same camera in a different housing.

The methods for doing the long exposure mod are the same as for the Vesta and ToUcam Pro. In fact, the layout of the circuit board of the PCVC840 camera is the same as that from a PCVC740. So no surprises. The only thing with the new board is that the via's are blocked with the green isolation coating. In the old ToUcam these via's were open, so you could put a wire through it to the other side. Also you have to scrape the coating off, to solder to the via's.

Other points of interest:

-    The USB cable is really short, only 150 cm. (instead of 300 cm for the old ToUcam)
-    You can (almost definitely) use a Mogg adapter designed for a Vesta, because the ToUcam Pro II does not have a recessed lens thread.
-    The ToUcam Pro II works with the same drivers as the ToUcam Pro (and vice versa).
-    The lenses are optically the same.
-    The case of the ToUcam Pro II is more solid
-    The sensitivity is the same as the ToUcam Pro (both for normal exposures and deep-sky)
-    The 352x288 cropped mode also works (with the ToUcam Pro driver version 1.0 and ToUcam Pro II version 1.02))
-    The red LED is even more annoying when not removed or painted over.

The inside with the backplate removed. With the dead bug method you CANNOT put the backplate back on the camera. Only if you remove the horizontal reinforcement rims in the backplate you may be able to close the case when you put the dead bug on the SAA8116 chip.

The wires to the 16510 chip. Also note the traces that I cut to avoid lifting the pins.
The connections to the pads.
The new 840 board and the old 740 board side by side. Surprise, surprise they are the same. (I had no unmodified cameras, so the amp-off and basic modifications to the 16510 chip are already done)
