Carlos, I've never had reliable luck using the 2nd Serial Port. The sysdef seems to get in the way. If you get it to work, I'd love to hear about it. Regards, Alex Johnson 10707 Haddington Houston, TX 77043 713.722.2859 (office) 713.722.2700 (switchboard) 713.932.0222 (fax) [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> -----Original Message----- From: Carlos Poblete [SMTP:[EMAIL PROTECTED]] Sent: Monday, April 23, 2001 5:48 PM To: Foxboro DCS Mail List Subject: I/A - 743CA communication Hello, We have the following question: Can we use an AW70 standard Serial Port (COM2) directly connected to the RS232 RS485 converter (Replacing an existing Digiboard Serial Multiport card) in order to connect the PC to a few (less that 12) 743CA or 760 controllers? Is this communication acceptable to the I/A System or this system "needs" the multiport card (Digiboard)? This problem is due to that the multiport has an ISA slot, and the new computer to replace the original one does not have ISA slots.
