hi here: http://www.anderswallin.net/wp-content/2006_11jog/jog.hal is a code that i need to place into my INI file. if i want to use my second 5i20 board, i need to replace joga m5i20.0.in-09 and joga m5i20.0.in-10 with joga m5i20.1.in-09 and joga m5i20.1.in-10
is this right? is there anything else i need to change if i use second 5i20 board. thanks aram > Yes, you could do as you said. Then you would need to tie +5VDC to pins > 16, 13, and 4, and ground to pin 8. BUT, there is a more efficient way. > If you use only 2 of the gates, it would be better to use gates A and C > (or B and D). If you were to use gate A and C, you could tie +5 VDC to > pins 16 and 4. This would prevent B and D from trying to drive their > outputs, and eliminates some possible noise and power problems in the > chip. > > The differential output is a way to double noise margins and increase > speed while still using 5 volt logic. In the case of a MPG, it makes the > signal on the cable from the MPG to the I/O more stable and noise free. > But it takes another pin for each signal, and you can change it to a > single ended (ie 1 wire) signal just before it goes to the 5i20 or 7i37, > and save 2 I/O pins. > >> Date: Thu, 26 Nov 2009 16:20:08 -0700 >> From: a...@conceptmachinery.com >> To: emc-users@lists.sourceforge.net >> Subject: [Emc-users] Pendant MPG >> >> Hi. >> I want to add pendant to my system that has 2 -5i20 and 4 -7i37 boards. >> >From WIKI I can see page - >> http://www.anderswallin.net/2006/11/jogging-emc2/ >> I am interesting in >> To save I/O pins, I first decode the differential signals to >> single-ended ones using a DS3486. >> How many I/O pins I can save with use of DS3486? >> I have 2 boards 5i20 and 4- 7 i37, so I may use extra I/O pins I need >> to >> use instead DS3486? >> >> I case if I want to use DS3486, how to wire it up? >> http://www.national.com/mpf/DS/DS3486.html#Overview >> >> On diagram http://cache.national.com/ds/DS/DS3486.pdf I can see >> INPUTS A; 1 and 2, and output A. >> >> INPUTS B; 1 and 2, and OUTPUT B >> INPUTS C; 1 and 2, and OUTPUT C >> INPUTS D; 1 and 2, and OUTPUT D >> >> My MPG has A+ A- B+ B-., How are they related? >> Is this right: >> A+ and A- (from MPG) to two pins { INPUTS A (on DS3486) >> and use OUTPUT A >> B+ and B- (from MPG) to two pins { INPUTS B (on DS3486) >> And use OUTPUT B >> And INPUTS C and INPUTS D left alone. >> >> Should I use DS3486 with some special adapter etc? >> >> Thanks >> Aram >> >> >> >> >> >> ------------------------------------------------------------------------------ >> Let Crystal Reports handle the reporting - Free Crystal Reports 2008 >> 30-Day >> trial.
