Introduction
RZ/N1 is a family of scalable ARM® based industrial Ethernet switches. Due to the integrated performant
ARM® Cortex®-A7 CPU, they are ideal choice for building products such as Programmable Logic Controllers
(PLC), complex remote-IO slaves, industrial switches, gateways or operator terminals.
RZ/N1 Family consists of three devices, out of which the RZ/N1D, is an industrial ethernet communication
System on Chip with 5-ports, in a 400BGA package.
This guide shall assist you to quickly start with your evaluation of the RZ/N1D device on the related Solution
Kit board(s) and the Solution Kit software and documentation. It represents a short guide for the first time users
with the instructions for the first startup of the board.
In addition to this document, please be aware of the extensive documentation on RZ/N1 devices, evaluation
boards and software that you may find in the Solution Kit Documentation directory.
The Solution Kit boards can solely be used for evaluation purposes. It is not allowed to use the boards for
commercial purposes.

1. Overview
The following chapters will help you setup the hardware and software environment and run a sample
application on your RZ/N1L evaluation board.
•The Solution Kit is being actively updated and new versions of it are iteratively released
•Current version of Solution Kit is providing a snapshot of the latest software and documentation
versions at the release time
The CONNECT IT! ETHERNET RZ/N1D Solution Kit is based on the RZ/N1D, a 5-port, industrial Ethernet
communication SoC in a 400BGA package. The device features two independent blocks integrated in a single
package –a communication block based on the proven multi-protocol R-IN Engine, as well as an application
block with a dual ARM® Cortex®-A7 and a variety of peripherals, including a DDR memory interface required
for rich operating systems like Linux. Along this external memory the RZ/N1D additionally includes 2 MB
internal SRAM. The RZ/N1D Solution Kit contains everything you need for fast evaluation and rapid prototyping
of multiple industrial Ethernet protocols.
The RZ/N1D Solution Kit contains
•RZ/N1D CPU Development Board
•IAR I-jet Lite debugger (incl. 20pin flat ribbon and USB-micro/A cable)
•USB Cable Micro / Type-A
•DVD RZ/N1x-DB Solution Kit for all RZ/N1x devices / boards
Additionally, one can order the RZ/N1-EB Expansion Board separately, that provides the user with the
possibility to use an expanded range of functionalities and RZ/N1D interfaces. RZ/N1-EB kit contains:
•RZ/N1-EB Expansion Board
•Power Supply 24V/750mA
•Power Supply Primary Adapters Euro/UK/JPN-US
The expansion board has no stand-alone capability and requires an RZ/N1D or RZ/N1S CPU board.

If you are using the expansion board together with RZ/N1D CPU Board, please remove the jumper
CN6.
1. JTAG Debug Connector
This connection is required for software development purposes, to be able to run and debug the
software on the target. The IAR Debugger cable has one unused key pin, therefore pin 7 of the J2
connector should be cut or bent, as shown below. After this step, you can attach your I-jet debugger
to the board via JTAG cable to the PC via USB.
Figure 2-2: Connector J2 with removed pin 7
Figure 2-3: I-Jet Debugger Connector
2. Power connector and serial-over-USB
The board is powered via USB connector CN10, if not attached to the expansion board. If you use
the CPU board standalone, please make sure that the jumper CN6 is ON, otherwise OFF. Please
connect the board to your PC via USB cable to the connector CN10. The same interface is used for
serial UART communication with the board, so if you have a windows PC, after connecting the

board via USB, you should be able to see a new device registered 4 new USB Serial COM ports.
You may use any of the terminal emulator on your PC to open a serial port connection to the board.
The board uses the 3rd port for UART output at 115200,8,n,1. On Linux PCs, if you have no other
serial-over-USB devices attached, this is accessed using /dev/ttyUSB2, provided you do not have
any other USB devices attached.
Figure 2-4: Power connector and serial over USB
If the board is not recognized by Windows, please install the FTDI driver that you may find under
…\YCONNECT-IT-RZN_V1.x\Tools\FTDI.
You can perform a soft-reset of the board by pressing SW4.
3. Ethernet Interface
The Ethernet connection to the PC or a PLC can be prepared using one of the two RJ-45 connectors
CN4 or CN1 (for an overview of connectors please check Figure 2-1). For running any Ethernet
fieldbus sample program, you can use any of the two connectors. There are two PHY Micrel chips
connected to these RJ-45 connectors.
If you are using the expansion board, Ports J23 and J24 can be used of real-time Ethernet and port
J22 is reserved for Linux. You can connect J22 to a dedicated Network Interface Card (NIC) on your
PC to open a secure shell to Linux. Linux accesses GMAC1 on the RZ/N1 device.

2.2 Expansion Board Setup
If you are using the expansion board together with your RZ/N1D CPU Board, here you may find some setup
notes for it. The expansion board comes with an external power supply to drive the expansion board and the
RZ/N1x CPU board plugged onto the connectors J1 and J2. Please note the position of the power supply
selection jumper below and ensure that the 12…24V position is chosen. This board expands the RZ/N1D or
RZ/N1S CPU boards with 3 Gbit PHY ports, an SD-Card slot, a USB Host as well as CAN, RS232, RS485,
PMODs, LCD display interface with integrated touch screen, etc.
