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/N1S, is an industrial ethernet communication
System on Chip with a 3 or 5-ports, depending on the respective chosen package 324BGA/196BGA.
This guide shall assist you to quickly start with your evaluation of the RZ/N1S 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/N1S Solution Kit is based on the RZ/N1S, a 3/5-port, industrial Ethernet
communication SoC in a 324BGA / 196BGA package. RZ/N1D 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 and a variety of peripherals. In contrast to the RZ/N1D, RZ/N1S includes only a single ARM®
Cortex®-A7 CPU without an external DDR interface, but with 6MB internal SRAM. Please refer to the RZ/N1S
device documentation for further differences. Also, the RZ/N1S Solution Kit contains everything you need for
fast evaluation and rapid prototyping of multiple industrial Ethernet protocols.
The RZ/N1S Solution Kit contains
•RZ/N1S 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/N1S 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.

schematics (RZ_N1S_DB_Board_Schematic) in respective board documentation folder in Solution Kit.
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 CN7
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.

2. Power connector and serial-over-USB
The board is powered via USB connector CN6. Please make sure that the jumper CN14 is ON.
Please connect the board to your PC via USB cable to the connector CN6. 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 with 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.
If the required 3.3V are supplied to RZ/N1S, the green LED24 will be lit and stay ON.

You can perform a soft-reset of the board by pressing SW9.
3. Ethernet Interface
The Ethernet connection to the PC or a PLC can be prepared using one of the two RJ-45 connectors
CN5 or CN1, as shown in Figure 2-5: Ethernet RJ-45 connectorsFigure 2-5. For running the
EtherCAT sample program you can use any of the two connectors. There are two PHY Micrel chips
connected to these RJ-45 connectors.

2.2 Expansion Board Setup
If you are using the expansion board together with your RZ/N1S CPU Board, here you may find some setup
notes for it. For more information refer to the board documentation in the Solution Kit. 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/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.
