Examples of communications setup screen
F1 (Menu): Displays the Table menu screen.
F6 (COM #): Sets a communication port number.
• Modbus protocol can be set to both COM1 and COM2. However, GCCU and GCCU or
Y-Protocol (GC1000/GC8, GC6, GCHC) and Y-Protocol cannot be set to COM1 and COM2
respectively.
• Items that cannot be set due to types and protocols are displayed with * (asterisk).
