3-3  Connecting the CX-Designer 
 
Use an RS-232C, Ethernet, or USB cable to connect the PT and computer so that screen 
data that has been created with the CX-Designer can be transferred to the PT. A modem can 
also be used. 
3-3-1  Connecting via RS-232C or Ethernet 
Connect the RS-232C cable from the computer to serial port A or B. The cable can be con-
nected to either serial port A or B, but cables cannot be connected to both ports at the same 
time. 
To use Ethernet, connect the Ethernet port on the computer to the Ethernet port on the PT.
