## Description

Features:Support ASCII text and RTU protocol automatic identification, no user setting in required.The meter can display 4 digit of serial port.Wide range of power supply voltage between DC7~36V. Large 0.56inch display area for only 4 digit ,more clear.The baud rate can be 1200bps/2400bps/4800bps/9600bps/19200bps/38400bps/57600bps/119200bps.Specification:-Display Digit:4-Display Size:0.56inch-Display Color:Red-Power Supply Voltage:DC 7~36V-Current:30mA-Wiring Diagram:-V+ :Power positive-GND: Negative power supply-A: RS485 BUS A-B: RS485 BUS B (note the wiring sequence, first connect the power cable to confirm the module works normally and then connect the communication line)-Communication interface: non-isolated, 485 bus and GND terminal common ground. If there are multiple devices on the bus, be sure to connect the terminating resistor to the bus end device.-Baud Rate:1200bps/2400bps/4800bps/9600bps/19200bps/38400bps/57600bps/119200bps-Size:79 x 43 x 21.5mm / 3.11 x 1.69 x 0.85in -Installation Size:76 x 39.2mm / 2.99 x 1.54in Package List:1 x Meter

Review: Undocumented, unstable, unusable - Zero stars - 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. 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.

### ⭐ 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. It's not worth messing with and I regret the purchase.

### ⭐⭐⭐⭐ Poor documentation
*by M***A on November 6, 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).

### ⭐ Without any documentation
*by J***S on August 15, 2023*

Arrived with no documentation at all, I searched the internet, and found nothing, I need the registers and their purposes to be able to know what so send to the unit over RS485.
