Hello Anders.
I have questions about 6 position rotary switch and 4 position rotary switch. Are they all one-pole type of switches or they need to be multi poles? About 4 Pushbuttons switches, are they all momentary type switches (normally open)? How many this electronics devises " I first decode the differential signals to single-ended ones using a DS3486 <http://www.national.com/pf/DS/DS3486.html> ." do I need? How many this type do I need "6-pos switch is encoded with an SN74HC148 <http://www.alldatasheet.com/datasheet-pdf/pdf/27887/TI/SN74HC148.html> into a 3-bit value." do I need? Can you also send some diagram of soldering/connecting DS3486 and SN74HC148 into the circuit? Thank you, Aram K. ________________________________ From: [EMAIL PROTECTED] on behalf of Anders Wallin Sent: Sat 2/24/2007 8:38 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] Hardware Feedrate Override Control > Dear All, > I have the current EMC2 2.1.0. and a Mesa 5i20 board.

Hi David, I documented some of my jogwheel hardware and HAL code on my blog http://www.anderswallin.net/2006/11/jogging-emc2/ adjusting feed override requires halui, but it's quite easy to do. If you have the 5i20 with the 'old' firmware then the secondary hardware encoders are broken (pinouts overlap), but with an MPG there's really no reason to use a hardware encoder counter, the HAL software encoder counter works just fine.
