Chapter 1 Introduction
The Serial Command Mode function described in this User’s Guide is built into the firmware of
the Command Mode models of Moxa’s NE-4100 Series of Embedded Network Enablers. All five
models, which are listed below, support auto-detecting 10/100 Mbps Ethernet.

! NE-4110S-CMD
Serial (RS-232) to Ethernet
— RJ45 type
! NE-4110A-CMD
Serial (RS-422/485) to Ethernet
— RJ45 type
! NE-4120S-CMD
Serial (RS-232) to Ethernet

Serial Command Mode serial commands are used to retrieve or configure parameters stored in
NE-4100 Series products’ flash memory. Since the commands are sent via the module’s serial port
(P0), Serial Command Mode gives serial device manufacturers the option to add local
configuration capability to their products. For example, card reader manufacturers can use the card
reader’s number pad to configure network settings (IP address, netmask, etc.) and serial settings
(baud rate, data bits, etc.), allowing end-users to configure the device on-site, without the need to
carry around and set up a notebook computer.
