DeviceMaster 1E: Connect the 10/100 port to the same Ethernet network segment as
the host PC using a standard network cable.
DeviceMaster 2E: Connect the DeviceMaster 2E using one of these methods:
• Ethernet hub, switch (10/100Base-T), Server NIC (10/100Base-T): Connect
a 10/100 port to the same Ethernet network segment as the host PC using a
standard Ethernet cable.
• Daisy-chaining DeviceMaster units: Connect the port labeled E1 (or E2) on the
first DeviceMaster to the port labeled E1 (or E2) on the second DeviceMaster or
other device using a standard Ethernet cable.
Do not connect RS-422/485 devices until the appropriate port interface type has
been configured. The default port setting is RS-232.
