RS232 COM PORTS
SCADA 3000 has two RS232 ports, one configured as DCE 9-pin female (COM 1) and the
other as DTE 9-pin male (COM 2). COM 1 is designed to connect directly to a personal
computer for local communications/programming. 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. The baud rate and communication type (radio or standard)
for each port is selectable via jumpers located under the top cover (see following figures).
The default Baud rates and communication types are listed below.
COM 1 Default Setting: 38,400 bps, Standard
COM 2 Default Setting: 38,400 bps, Standard
