Ethernet Communication
482C27 includes an Ethernet port for computer control. The unit’s IP address must be set up before any remote
communication can commence.
The steps to set the IP address of the 482C27 are as follows:
Connect, either directly with a crossover CAT5 cable or through a hub, to a single unit. This unit is presumed to
have a Unit ID of 1,
Set the IP address using an independent utility from Lantronix called DeviceInstaller
TM.
