Operation
TCA-3 Temperature Monitoring System

The TCA-3 monitoring system supports SOCKS4 and SOCKS5 Proxy servers, which can be set up using the
Remote Gateway Configuration Utility. In environments where other proxy servers are used, a router may
be required to act as a proxy client for the TCA-3 monitoring system.
Generally MAC numbers do not require registering on the network; if it is a requirement, register the
unique MAC number for each TCA-3 monitoring system.
All communication to the hosts will be initiated from the TCA-3 monitoring system using HTTPS on port
443.
The TCA-3 monitoring system does not need to accept incoming sockets from the hosts, only to be able to
open sockets to them.
All traffic is initiated from the TCA-3 monitoring system as out going secure web requests.
Aside from needing access to DNS servers, the TCA-3 monitoring system will not communicate with any
other hosts on the Internet.
Useful destination addresses for communications for the TCA-3 monitoring system web application are as
follows:
• 8.26.65.62 listener.sensornetworkonline.com
• 83.26.65.62 secure.sensornetworkonline.com
4.3 Internet security
Communication from the TCA-3 monitoring system to the Secure Servers utilizes the HTTPS protocol and
only relies on an outbound connection over port 443. As communication between the TCA-3 monitoring
system and the servers is initiated from the TCA-3 monitoring system, there is no need to open inbound
ports on the firewall. HTTPS over port 443 is a standard communications protocol for secure Web traffic
(e.g. credit card transactions).
Data sent over the Internet utilizes two forms of encryption:
• SSL Encryption, the same "padlock" feature that many Web sites use to ensure Web purchases are
secure.
• Certificate Encryption, each gateway is issued a unique, digitally signed certificate that is associated
with its serial number.
