the RS232/RS422 port and the Ethernet port, provides an easy way to set up ties and sets 
of ties.
The program is compatible with Windows 2000, Windows XP or later. Updates can be

passwords, or locally created file names.
•  Unless otherwise specified, the following characters are invalid or not recommended 
for SMX inputs: + ~ , @ = ‘ [ ] { } < > “ ; : | \ ? and space

this program on a Windows-based PC connected to either of the SMX serial ports or the 
Ethernet port (see b and d, on pages 7 and 8, for connection information). It cannot be run 
from the DVD.
