N4IOA01 FAQ
I have the N4IOA01 DC 12V 24V RS485 To 4-20MA 0-20MA Current Signal Generator PWM To Current Analog Converter Modbus RTU 03 06 DAC Module. Why is the command to set a new current 01 06 00 00 01 90 88 36 at the time of receiving/transmitting via RS485, the current drops to 10-20% (3.2, 3.4, 3.4, ... 4.0). What can be done to prevent this from happening? It is impossible to reduce the receiving/transmitting time, because the maximum exchange rate is 19200. It is also impossible to cancel the response to the command, because there is no broadcast command at address 0. Help me to solve the problem I have 4 of them. I wanted to buy more, but I need to solve this problem. Eletechsup : N4IOA01 is a low-cost slow RS485 To 4-20MA 0-20MA current signal generator. Please lengthen the sending interval. For example, change the current value once...

UD23A08 FAQ
Customer : I bought a UD23A08 8 Channel USB COM Serial Port UART Relay Board on aliexpress (order Nr 3051804136187061) and I am trying to communicate with it. Unfortunately, I am not able to find any protocol specification neither for AT commands or 8 bytes commands neither serial port configuration (I believe 115200 baud rate)....
