5.0 Enabling RS-232/Ethernet Controls
Overview
RS-232 commands may be sent over an Ethernet connection to control the Model 458-3SL. This is
made possible by a Lantronix XPort transceiver installed in the unit. A one-time set up must be
performed to assign an IP address to the transceiver and configure a virtual COM port. This is all
done using a remote PC. It requires one software installation to assign an IP address to the
transceiver and a second one to configure the virtual COM port. Once this is done, all of the
commands available in section
4.0 RS-232/Ethernet Controls
may be used over the Ethernet
connection.
Before You Begin
Connect the 458-3SL and a remote PC to the LAN using Ethernet cables. Please note, when
connecting the Model 458-3SL directly to a PC a crossover Ethernet cable is used for communication;
when connecting to a network (through a switch or router) a straight-through Ethernet cable is used.
L
Administrator access to the remote PC is required.
