FAQ

Q: What does the "X" suffix indicate in 2711-K5A2X?
A: The "X" typically indicates a specific hardware revision or packaging variant. The terminal is functionally equivalent to 2711-K5A2/H.

Q: Is the 2711-K5A2X compatible with PanelView Plus software?
A: No. This terminal uses PanelBuilder 32 for application development, not FactoryTalk View ME.

Q: Can I add a touchscreen to this terminal?
A: No. The 2711-K5A2X is keypad-only. For touchscreen capability, select the 2711-T5A or 2711-B5A series.

Q: Is this terminal still manufactured?
A: No. The PanelView 550 is discontinued. Available through surplus and refurbishment channels.

Selection Tips

• Verify DH-485 network infrastructure exists for controller communication
• Confirm AC power (100–240V) availability
• Ensure PanelBuilder 32 software is available for application development
• Consider keypad-only vs. touchscreen requirements for the application
• For new installations, evaluate PanelView Plus 600 or 700 series with Ethernet
