[QUOTE="harm lok, post: 1089503, member: 415123"] Thanks for the many reactions and useful links. After my calculation for angles versus pulses i have realized a parallel interface for the V-box sensor input. Fist i tried to connect a opto-coupler but when i draw some milli amps from the V-box sensor connection the V-Box is showing an Err2 mission. Unfortunately i have lost the satellite position settings stored into the V-Box because i have to reset the V-Box to get to work again. After that i have choose a method that did not put any current from the V-Box. [ATTACH type="full"]130698[/ATTACH] I have placed a bridge receiver over the sensor pulse signal with a resistor 1:5 divider to bring down the pulse voltage. This circuit does the job. It operates perfect without taken any effect on the normal V-Box operation. I have connected the pulse to a cortex0 processor programmable from a free editor/assembler. My next job is to program that will convert the pulses into the calculated degree , so i get a degree's display instead of pulse. I have already added a F-ram for my future plan to make a complete disecq positoner. [ATTACH type="full"]130699[/ATTACH] This is a screen save of the pulse from the rectified (V-Box in Action ) pulses and the pulse ready to be counted en converted. If you have additional suggestions or remarks , please respond. Will be continued .. [/QUOTE]
