10 Serial Communication 

The SCADAPack LP controller is equipped with three serial communication ports. Two of the serial 
communication ports support RS-232 serial communication and one port supports RS-485 serial 
communication.  

Serial ports on the SCADAPack LP controller are designated COM1, COM2 and COM3. Refer to 

Figure 2:  SCADAPack LP Board Layout

 for the location of the serial ports. 

10.1 

RS-232 Serial Communications Ports 

The two RS-232 serial ports are designated COM2 and COM3. 

All RS-232 wiring must use shielded cable. The shield should be connected to chassis ground at one 
point. Failure to properly shield the cable may result in the installation not complying with FCC or 
DOC radio interference regulations. 

10.1.1 

COM2 RS-232 Serial Port 

The following table shows the serial and protocol communication parameters supported by COM2. 
These parameters are set from TelePACE, ISaGRAF Workbench or from an application program 
running in the SCADAPack LP controller. Default values are set when a Cold Boot or Service Boot 
is performed on the SCADAPack LP controller.
