Information to Gather
Before you install RealPort, you need to determine:
• The hostname or IP address to assign each unconfigured Digi device.
• The number of ports for each Digi device. Include any Xem PORTS Module ports that are
attached to the Digi device.
• Determine the link speed between the host machine and the Digi device if a slow WAN link (for
example, a 56K leased line) connects them.
Configuring a PortServer or PortServer II for RealPort
Use this procedure to configure a PortServer or PortServer II for use with Digi RealPort drivers.
