Evaluation Board User Guide
1 Introduction
This document describes how to use the RS9110-N-11-24 EVB. It
describes the sequence of commands and set-up requirements to quickly
evaluate the major functions of the modules.
Chapters Using the Evaluation Board in UART mode to Evaluating the
Module in Infrastructure mode describe operation using the UART
interface. Using the Evaluation Board in SPI mode describes operation
using the SPI interface. Upgrading Firmware describes the firmware
upgrade procedure. Even if the user does not plan to use the UART
interface, it is recommended to go through the UART section because all
the set-ups to evaluate different functionalities of the module in UART
mode are directly reusable in the SPI mode also.

2 Components on the EVBs
The RS9110-N-11-24 EVB has various switches and headers to enable the user to
configure it for different scenarios1. The figure below shows the various
components. The exact EVB may differ slightly from the pictures below due to
different PCB versions or minor changes.

The power for the board can be supplied through this connector.
UART Header for MCU
If the EVB needs to be connected to the serial interface of an MCU platform, this
header can be used. The voltage level of the UART TX and RX pins of this header
is 3.3V. The Ground pin should be connected to a corresponding ground signal of
the MCU board.

These switches are used to select the UART DB9 connector or the “UART Header
for MCU” for communicating using the UART interface. The direction shown with
the thick red arrow is to select the DB9 connector. The direction shown with the
thick black arrow is to select the UART Header.

3 Using the Evaluation Board in UART mode
The following sections describe how to use the Evaluation Board in UART
mode.
3.1 Configure Serial port in computer
To know the COM port name, check the computer’s Device Manager settings.
The COM port name is displayed in the window. Hyperterminal or Teraterm should
be opened and configured accordingly with this COM port name.
The steps for configuring HyperTerminal are shown below.

3.2 Configure Serial Port Monitor in the PC
The actual bytes exchanged between the module and the Host PC may
not all be readable on Hyperterminal or Teraterm because of ASCII
conversion. A serial port monitor
free package is available at http://www.serial-port-monitor.com/ , while
other similar software such as Hterm, Docklight etc. also provide good
interfaces to simultaneously view ASCII and actual bytes exchanged in
the UART interface. The following sections assume that HHD Free Serial
Port Monitor has been installed from the above link.
Open the “HHD Free Serial Port Monitor” BEFORE opening the
Hyperterminal or Teraterm. Click on File -> New Session. Select “Serial
Port Monitor”. Select the appropriate COM port and “Request view” for
the display format.
