Notes 
Com3 is supported only when the SCADAPack Lower I/O module is installed. Com4 is 
supported only when the SCADAPack Upper I/O module is installed. 
Extended addressing is supported only by the Modbus RTU and Modbus ASCII protocols. 
To optimize performance, minimize the length of messages on com3 and com4. Examples of 
recommended uses for com3 and com4 are for local operator terminals, and for 
programming and diagnostics. 
Refer to the TeleBUS Protocols User Manual for further information on protocols.
