Application Areas
Overview
• SS supports an enhancement transmission method "TCP/UDP
multicasting", which transmits serial device data to multiple hosts
simultaneously.
• Max. 32 hosts (incoming+outgoing) per one port allowed.
• Max. 16 outgoing connections (registered remote hosts) per one
port allowed
• Each registered TCP host can have a backup host
• UDP host mode does not support backup host since there is no way
to check status of primary remote host.
• Multicasting feature is very useful in application areas where user
needs to transmit a message to several display signboard devices
simultaneously.

Other Security Features
Application Areas
SSL Encryption: Overview
• SSL creates a secure connection between a client and a server, over
which any amount of data can be sent securely.
• By setting the cryptography method as one of SSLv2, SSLv3, SSLv3
rollback to v2 or TLSv1, the Super Series can communicate with
other device supporting SSL/TLS cryptography method in encrypted
sessions.
• SSL configuration settings are available only when the host mode is
set to TCP or Modem Emulation mode.
• SSL works by using a private key to encrypt data that's transferred
over the SSL connection.

• The SS can capture all system and port data, and save it into a log file.
This buffer can be viewed from the web, saved to memory, or saved to
a Flash Card, syslog server or NFS server.
• System logs track events such as logins, authentication failures,
system configuration changes, and more.
• Port logs document the data flow through the SS serial ports.
• In addition, the SS can be configured for system alerts and
notifications. It can send email messages when an alarm message is
detected in the serial port data.
• The SS uses SMTP for sending email notifications and SNMP for trap
alerts.

www.sena.com
Overview
• SS supports SNMP that provides status and performance of connected
serial devices through their Ethernet connections.
• Applications such as NMS or an SNMP browser can exchange
information with the SS.
• The SS supports SNMP authentication, Login, and Link up traps.
• The SS supports both versions 1 and 2 of the SNMP protocol and
delivers the System and Port alerts as traps.

Dynamic Domain Name
1. Overview
2. Configuration and Connection
www.sena.com
Overview
• Dynamic DNS Protocol enables users to access the SS via a
domain name for floating IP environments such as DSL line
and DHCP.
• To use this service, users must set-up an account in Dynamic
DNS Network Services and add domain name, user name and
password on the SS DDNS configuration page.
• Whenever user reboots the SS in floating IP environments, it
sends updated IP address to Dynamic DNS Network Services.
www.sena.com
38
Configuration and Connection
• Access the SS web interface
– Choose Network --> Dynamic DNS configuration
• Access the SS web interface and use domain name
• For e.g., ismdemo.dyndns.biz

User Web Customization - HTML pages
User Web Customization – CGI & Java pages
Serial Filter Application
www.sena.com
Overview
• Web customization options
– Plain HTML files
– CGI written in C
• User application implementation
– Filter applications in C
– Other applications in C or shell scripts
• To quickly develop custom applications that run on the HelloDevice
Super Series, SDK (Software Development Kit) is needed.
• SS SDK is a 256MB CF card composed of executable binaries
(including gcc), header files, and library files.
– Executable binaries run on SS (MPC855T Linux)
– Header files and Library files are compatible with SS platform
• With SS SDK, users can compile their own C/C++ source code to run
on SS without installing cross-compile utilities on their PC.

User Web Customization - HTML pages (1/3)
Preparation
• If you are using Windows, using SCP (secure copy
protocol) client tools for Windows will be handy for file
transfer from/to SS
• Winscp (GUI)
– Download @ http://winscp.sourceforge.net/eng/
– Install as other applications
• Pscp (command line interface)
– Download pscp.exe @
http://www.chiark.greenend.org.uk/~sgtatham/putt
y/download.html
– Copy pscp.exe into C:\Windows directory

42
User Web Customization - HTML pages (2/3)
Running User HTML file
• Prepare
index.html file
and other
related files (e.g.
index.html and
webtest.swf)
• Just copy the
files to SS,
/usr2/usrweb
directory using
SCP tools (e.g.
winscp) and it
will work!

Serial Filter Application (1/4)
SS Serial Filter Structure
• Users just need to write
filter application only to
customize serial port
application rather than
writing whole source code
• Typical situation for serial
application customization:
– Add/remove protocol
header
– Periodically check serial
device
www.sena.com
49
Serial Filter Application (2/4)
Sample file
• Location = /mnt/flash/sample/filter
• periodic_filter.c
– Periodic query of the serial device application might
start from here
• empty_filter.c
– Do nothing. Adding/removing header application
might start from here
www.sena.com
50
Serial Filter Application (3/4)
How to
• Log into the SS (Telnet or SSH)
• Copy sample file from SDK to working directory (e.g.
/mnt/flash/work)
• Compile source file (Be careful with compile options)
gcc -o myfilter myfilter.c -L/mnt/flash/lib –lpthread
• Copy compiled binary to /usr2 directory
• Specify filter application and arguments using
configuration web or menu configuration

Door Access Application (Customized)
• Target Device : RF-ID Card Reader
• Application Details:
– Customer has added a user customized filtering
program that transmits only needed serial-based
RF's to the management station through the SS110.
– As a result, the time that is required to process
visitor’s door access requests has been dramatically
minimized.
– Why SS instead of the PS?
• Fast response required Local protocol parser
application is required on the SS to reduce the
network traffic
