1. Introduction
Lantronix serial device servers provide the ability to communicate serial data across an Ethernet network.
The SDSTX3110-124-LRT-B contains (2) 10/100Base Fast Ethernet ports that can be configured to one or
multiple redundant servers. It has four (4) DB9M Serial Ports.
Data transmission security is assured through HTTPS, SSH, and SSL data encryption on all three models.
They come with COM port redirector software enabling communication of serial data to a virtual COM port on a
server or can be used in pairs to provide serial tunneling across the Ethernet network. They are hardened devices
designed to operate in the harshest environments. Enclosed in an IP30 enclosure and accepting input voltage of
12 to 48 VDC, the device is certified to operate in temperatures of -40°C to +70°C.
