Revisiting this subject due to a pressing need.
The way I understand it, there are two methods of using a Haas External, stand alone indexer on a VF machine.
One, is to program moves into the stand alone indexer, and then use the CNC interface cable to trigger those "dumb" ( or simple ) indexing moves. This is the four wire cable that basically shorts to pins to tell it "move now", using an "M21" within one's G-coded program. After the move the indexer will send a signal telling the control, "All done now. Carry on." My understanding is that the four wire connection and using the "M21" are all that is necessary. ( aside from programming the indexer, locally )
Is this a correct understanding?
The second way, is to use an RS232 cable to interface with the indexer, and allows for more complex moves that are commanded down stream to the indexer with a series of commands, and said moves may not even be similar to each other. MY understanding is that this is a true two way communication over the RS232 cable. What is not clear to me is if the other ( four pin cable ) is also needed for this.
As well, the instructions for this leave A LOT to be desired from my point of view, so I am looking for someone that uses this method in effort to see if they can better explain it or even provide an example of its usage.
I get lost after the line about DPRNT...
Anyone?
Thanks.
