Appendix E: External Server and Remote Services

X-317™ Users Manual

need to be opened in the router, security is not compromised. See section

Advanced Network

Tab

for

more information..

Connection String

With Remote Services enabled, a connection attempt will be made periodically according to the
Connection Interval setting in the

Advanced Network

setup tab. The Connection String is a user-

defined character string configured in the

Advanced Network

tab.

The connection string is also sent at the same interval once the connection is open. The external server
is responsible for closing the connection when it is done.

Remote Commands

Once the connection is open, the remote server can issue HTTP GET requests to the device for XML
files. The X-317 does not support “events” and does not send unsolicited state.xml files.

Request about.html:

GET /about.html HTTP/1.1\r\n\r\n

Set Analog Output 1 to 50:

GET /state.xml?an1State=50 HTTP/1.1\r\n\r\n
