1.13. Secure Gateway
For enhanced data security when using an IP/Ethernet connection or a serial connection
into an IP terminal server, Emerson Energy and Transportation Solutions recommends
adding an industrial router with VPN and firewall security. Recommended solutions
include the MOXA EDR‐810, the Hirschman Eagle One, or the Phoenix mGuard rs4000 (or
equivalents). An example of how to install one of these devices to the RTU can be found in
the Emerson Energy and Transportation Solutions MOXA® Industrial Secure Router
Installation Guide (part number D301766X012). For further information, contact your
Emerson Impact Partner or the individual vendor’s website.
