Chapter 9: Communicating with SCADA 3000
Radio Vs. Phone Communication
The SCADA 3000 software offers you the most flexibility when it comes to communicating
with your SCADA 3000 RTUs. You can set up communication by data radio or phone line or
a combination of both. The software allows you to configu io. Radio allows the PC to be in
constant communication with all connected RTUs all of the time. Real-time information is
available on a continuous basis. In this mode the SCADA 3000 software will perform alarming
and data logging from the PC.
When SCADA 3000 RTUs are connected via phone line the software can dial up each unit to
retrieve and display information on an as-needed basis. In this mode, alarming and data log-
ging are performed from the RTU itself.

RS232 Communication Ports 1 & 2
The SCADA 3000 has two RS232 communication ports, one configured as DCE 9-pin female
(COM 1) and the other as DTE 9-pin male (COM 2). COM 2 is used to communicate with
SCADA 3000 via a radio modem (optional). The radio modem would connect to COM 2
directly with the appropriate cable. COM 1 is designed to connect directly to a personal com-
puter for local communications/programming. The baud rate and communication type (radio
or standard) for each port is selectable via jumpers located under the top cover (see Appendix
D). The default Baud rates and communication types are listed below:
COM 1 Default setting: 38400 bps, Standard
COM 2 Default setting: 38400 bps, Standard
