It's not worth messing with and I regret the purchase. ### ⭐⭐⭐⭐ Review *by M***A on 6 November 2021* I spent days trying to communicate this display with Modbus RTU. Poor documentation. Finally, browsing in other websites I found some details about modbus registers to be pointed to (40001 to 40007). The device doesn't respond to Modbus requests, it only accepts commands to change the value displayed, decimal point, brightness and other setting modifications. The device has a jumper inside which I have not idea what is for. ## Frequently Bought Together - RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7 ~ 36V - LED 7 Segment Display, MODBUS-RTU Display Module, 4 Digits Display with RS485 Serial Port for PLC Communication (5-36V) - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/446523264-rs485-display-0-56-inch-4-digit-led-display-rs485](https://www.desertcart.tn/products/446523264-rs485-display-0-56-inch-4-digit-led-display-rs485) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
