TVM802 and Windows 8 setup
The Windows Host Machine
The TVM requires three data connections to a host PC. I highly suggest a dedicated machine to control the TVM. I bought a relatively simple laptop with three USB ports, Ethernet, and Window 8. Windows 10 should work just as well.
The basic Wiring
The TVM comes with three data ports that must be connected to the PC. The machine commuinication runs through an etherent connection. It's easiest to get a crossed ethernet cabel and connect the TVM directly to the PC. Don;t put the machine on your shop network. It's not worth the hassle. If you want tp make sure that the machine is sending and receiving data, get a cheap dumb ethernet router that has LEDs and two ethernet cables that are not crossed. Don't use a smart hub or modem that puts additional DHCP traffic on the connection.
The ethernet port is set to the fixed IP 192.168.0.8 and port 701. You can't change these settings until you successfully connect to the machine!
Next to the ethernet connection are two USB connections that hook the cameras to the PC. The picker does not use any of the image data internally. All image processing is done on the host computer. Connect the cameras directly to the computer. Do not use a USB hub!
The cameras are Microsoft XBox cameras. Don;t use the driver that comes with the machine. WIndows 8 and10 should recognize your cameras instantly. Make sure that they show up in the hardware manager, and use any video viewer to verify that the cameras are delivering images.
How To Hook Up Ethernet
The ethernet connection has become somewhat of an issue for some users. A fixed IP is relatively uncommon in office networks. So here is how you do it. Assuming that the machine is hooked to the PC as described above, open your network settings. Go into Ethernet Propertis, then select TCP/IPv4 and open the dialog.
Set the first choise to use a fixed IP and enter 192.168.0.14. The second line is the subnet mask. Set it to 255.255.255.0. The standard gateway is ignored, but set it to the standard 192.168.0.1. The DNS entries should be set manually to, but the field must be left empty.
If you get an ethernet timeout instead, go through all the fixed IP ethernet settongs again. swap cables, add a router, check for blinking LEDs. Still not working? Ask a network administrator to help you with the network setup (avoid having a wireless network running on the same machine). Check if there are other ethernet port on your machine.
When the ethernet works, change to the Move window and try out all the motors. At the bottom right, there is a panel that can step through every conceivable motion. If there is another panel, clivk Move again. If everything work, it's time to send the machine home - oops - sent the pick-and-place head to its home position. Click on Home and Run' The head should position itself at the back right corner of the machine.
Testing Camera Settings
Use the Move commands to send the head all over the machine. Get familiar with the chinese logic of naming and positioning user interface elements. When you are done, ttake a look at the camera window. Double-clicking the window cycles between up facing camera view 1: nozzle alignment, upfacing camera view 2: chip alignment, and downfacing caera view 3: PCB marker search. Make sure that the up and down facing views are assigned correctly. If not, fix it in the settings by changing the ca,era ID.
Well, I hope that everything works for you so far. The pumps are pumping, the index pin is pinning, the nozzles are rotating and lifting, and the carriage is carrying.
Sorry for the bad photos and the German text. I hope that this still helps.
