I doubt the Pluto has enough gates for a decent serial interface along with good set of peripherals. It could be done with our 7I43 though. Its just a minor change from the USB-HostMot2 firmware to interface to a internal UART instead of the USB data. I think our parser code has a UART interface IFDEFed out at the moment. But the real problem is using it. Other than (upcoming?) Modbus support, I dont think there is any support for serial interfaces in EMC. Regular PC RS-232 serial ports are probably too slow for most real-time tasks anyway at about 90 uSec per character (10 bits 115200 baud)... > > > -----Original Message----- > From: Chris Radek [mailto:[EMAIL PROTECTED] > Sent: Wednesday, December 03, 2008 9:07 AM > To: Enhanced Machine Controller (EMC) > Subject: Re: [Emc-users] Pluto-P > > On Wed, Dec 03, 2008 at 08:57:11AM -0600, Len Shelton wrote: >> What exactly is the purpose of the Pluto-P interface?
