It's not worth messing with and I regret the purchase. Review: Poor documentation - 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. ## Features - POWERFUL FUNCTION - Support ASCII text and RTU protocol automatic identification, no user setting in required. Widely used in printing, chemicals, plastics, building materials, furniture, packaging, textiles, metallurgy, etc. - DC7-36V - Wide range of power supply voltage between DC7~36V. - FOUR DIGIT LED DISPLAY - The meter can display 4 digit of serial port. - 0.56INCH DISPLAY - Large 0.56inch display area for only 4 digit ,more clear. - BAUD RATE - The baud rate can be 1200bps/2400bps/4800bps/9600bps/19200bps/38400bps/57600bps/119200bps. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YB615PW | | Brand | Acogedor | | Brand Name | Acogedor | | Color | Red | | Customer Reviews | 3.4 out of 5 stars 8 Reviews | | Item Dimensions | 2.99 x 1.54 x 0.85 inches | | Item Weight | 0.1 Kilograms | | Item dimensions L x W x H | 2.99 x 1.54 x 0.85 inches | | Manufacturer | Acogedor | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 7 Volts (DC) | | Model | Acogedorv0ywgf8ecr | | Part Number | Acogedorv0ywgf8ecr | | Power Source | Battery Powered | | Style | Modern | | Style Name | Modern | | UPC | 719233607992 | ## Product Details - **Brand:** Acogedor - **Color:** Red - **Item Weight:** 0.1 Kilograms - **Power Source:** Battery Powered - **Style:** Modern ## Images ![RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7~36V - Image 1](https://m.media-amazon.com/images/I/51-oe4IEXLL.jpg) ![RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7~36V - Image 2](https://m.media-amazon.com/images/I/41wowYL6cWL.jpg) ![RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7~36V - Image 3](https://m.media-amazon.com/images/I/519I8r-w6bL.jpg) ![RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7~36V - Image 4](https://m.media-amazon.com/images/I/51U4aa+YEnL.jpg) ![RS485 Display, 0.56 Inch 4 Digit LED Display RS485 Serial Port Tester Communication MODBUS-RTU/ASCII Protocol 30mA DC 7~36V - Image 5](https://m.media-amazon.com/images/I/61z144u1V+L.jpg) ## Customer Reviews ### ⭐ Undocumented, unstable, unusable - Zero stars *by B***L on January 23, 2024* No manufacturer documentation online, a hobbyist has published information that is helpful but incomplete, and having gotten the device to work once it has repeatedly lost its settings and finally will not accept new settings.
