Asia Drivers

[kolias]

Have a hard time finalizing wiring on my driver board

I bought this 4 Axis driver board from “I Wanne Buy” in Hong Kong which is similar to the one sold by “CNC-IN” in China. It has the Toshiba TA8435H chip and besides the DB25 parallel port connector at the back it also has a DB15 connector for the 5th Axis extension and a DB9 connector for the limit switches.

The 2 page manual that came with it is written in broken English and difficult to understand.

Has anyone had any experience with it?

If someone has a wiring schematic of this board woold be ideal. My problems now:

Manual speed control, there is no indication what to do with it
Manual control connector, to where?
External input, how to wire?
Semi Flow, what’s this?
Relay output, what / how to wire?

might help if you upload what documentation you have, like a picture with pinouts or something.

I'm guessing you're supposed to connect a relay to the "relay output" pin so that the computer can turn the spindle on/off, but it's hard to tell just from the wording..
