A Lantronix Company SCS3230 System Administrator's Guide

When connecting devices to the SCS3230, be sure to use Lightwave Communications
cables and adapters to ensure the proper transmission of data signals. If a device has
an RJ45 serial port, use the manufacturer's cable included with the equipment to
convert the RJ45 serial connector to a DB9 or DB25 connector, and then use a
Lightwave Communications adapter to convert back to RJ45 to attach to the device
port. Directly connecting the RJ45 port on the SCS3230 to the RJ45 port on a third-
party device may not allow for the proper transmission of data signals.
