Laseshark Connections

Macpod:
What is important to keep in mind when connecting lasers to the lasershark are that there are two analog channels (A and B), and one TTL channel (C).

TTL means the output can be turned on or off only.
Analog means the output can be turned off, turned on 10%, 20%, etc.

The LaserShark is NOT a power source for lasers. You will need to power the LaserShark using an appropriate power supply. The LaserShark is intended to provide a signal to control a laser module only.

Markings on laser module inputs vary wildly so without additional information I cannot say if the CN1 input is actually the input or not. Do you have a manual for this module or an image of the inputs and labeling?

Hi there,

I have attached the image to the post, did it not come up? Regarding the power: the laser came with its own power supply so that shouldn't be a problem.

Macpod:
Thank you. The original link did not appear. It is possible that particular website does not allow off-site linking. This forum has an ability to upload images to the boards by the way. They format a little better than off-site links too (for now.. I'm going to have to fix that IMG tag!).

As for this driver, it looks like one of the super-common and low cost O&E dual TTL signal controlled diode drivers. Normally the pcb is potted on these but I guess they left this off to make this driver as cheap as possible.
It also looks like they didn't include a Peltier for diode temperature regulation with this module assembly. CN1 is the header which normally connects to this. DO NOT CONNECT CN1 TO THE LASERSHARK!

If you look on the back of the plastic cover there should be markings indicating what connector does what.
You will want to connect the "GREEN-LASER Blank+" pin to one of the LaserShark's laser +channel lines. Next you will need to connect the "GREEN-LASER Blank-" pin to the respective LaserShark laser channel's GND pin.

The "GREEN-LASER signal header in your image has been marked "+GT-".


Which channel (A, B, C) doesn't matter. The analog channels (A and B) are just as capable of controlling TTL signal controlled laser drivers as channel c (the TTL-only laser channel on the LaserShark).
