Hi all,
I'm currently configuring Mach3 to run my HDBB2, DG4S-08020 servo drives and ENI-1024 encoders.
I have a couple of questions regarding the parallel port outputs:
1. When testing the outputs from the LPT / parallel port I'm getting a 'high' of 3.4v and a 'low' of 0v. Is this correct? LPT is set to run in EPP mode with DMA3 selected in Bios. My BOB is TTL level and I can activate output relays connected to this.
2. With charge pump enabled on Pin 14, using a multimeter to test voltage output I get 1.7 - 2.2 volts depending. I know its difficult to read the CP output this way as its a 12.5 khz frequency, but does this sound roughly right and will it power the CP circuit on the HDBB2?
Thanks,
Jim
