It features a 5.3-inch blue monochrome display with resistive touchscreen operation and a resolution of 256 x 128 pixels. Operating on a 24 VDC input power supply, this terminal provides local operator control and monitoring using RS-232 (DH-485) communication along with a dedicated RS-232 printer port.\u003c\/p\u003e\n\u003ch3\u003eDisplay and Communication Capabilities\u003c\/h3\u003e\n\u003cp\u003eThe 2711-T5A9L1 enables operators to view process status, active alarms, and system data on its high-contrast 5.3-inch monochrome screen. Touchscreen capability allows intuitive input directly on the display panel for immediate control adjustments.\u003c\/p\u003e\n\u003cp\u003eFor communication, the terminal uses an RS-232 port supporting DH-485 protocol to exchange tag data and control commands with SLC 500, MicroLogix, or legacy PLC controllers. A separate RS-232 printer port allows connection to external serial devices for logging alarm histories and printing real-time process reports.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e2711-T5A9L1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eOperator Interface Terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003ePanelView Standard (PanelView 550)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Size\u003c\/td\u003e\n\u003ctd\u003e5.3 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Type\u003c\/td\u003e\n\u003ctd\u003eBlue Monochrome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Resolution\u003c\/td\u003e\n\u003ctd\u003e256 x 128 pixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperator Input\u003c\/td\u003e\n\u003ctd\u003eTouchscreen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocols\u003c\/td\u003e\n\u003ctd\u003eRS-232 (DH-485)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAuxiliary Port\u003c\/td\u003e\n\u003ctd\u003eRS-232 Printer Port\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.09 lbs (0.95 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What primary communication protocol does the 2711-T5A9L1 support?
