How to setup a Cellular Data Channel RTU that uses an Intermax
This is an overview of how the data flows from DATRAN VI to the RTU:
DATRAN VI → LAN / WAN → Internet → Cell network → Maxon Intermax modem → Q03 RTU
1. Add a _Comms_Object_ for the Cellular Data Channel with these properties:
a.TCP Port = 14000
b.Inactivity Timeout = 0 msec
2. Add a _Comms_Object_ for the Q03 RTU with these properties:
a.RtuActive = True
b.Address = 1 (this is the address/station number of the Q03 RTU)
c.Channel = CellularNET (this is the name of the Cellular Data Channel)
d.Poll Interval = 1 hr (or more as it can get quite expensive if the poll interval is set too short)
3. Add any exceptions in your firewall whether on the DATRAN VI computer, organization server, router,
etc. to allow incoming/inbound TCP connections from anywhere in the Internet to this TCP Port on this
DATRAN VI computer. Use HyperTerminal to test the connection to this TCP Port.
