Demo Gateway

Posted on by

For user to get familar with CCN Gateway, we build up simulated DEMO Gateway.

This demo Gateway link with 6 CCN chillers, each has same bus number of 0, element addreses are from 1 to 6.

The username to acces is:  admin, no passowrd is needed.

For modbus gateway, the acces point is http://demo1.hvacrcontrol.com

For BACnet gateway, the access point is http://demo2.hvacrcontrol.com

User could use modscan or VTS to test the modbus/BACnet function. The port number is defined in the Gateway’s general setting section.

Because the accsss is open, if there are users operate it concurrently. it would behave strangely. If you want exclusively operate it, please contact us, we would give you other private access point.
