rs485

Hello, I am a student at Escuela de Ingeniería de Gipuzkoa, and I am currently working on a project. The main goal is to estimate the electric consumption of a double-flux mechanical ventilation system (its motor), to do so, we are using an electric curent meter (SDM120M) and a RS485 to LoraWAN...

I hope I am knocking on the right door here. I have a small RS485 network with a master and two slaves that has been running for more than a year now. I recently replaced a seemingly unrelated power supply and started to experience communication failures. I checked the bus using a differential...

Hi, I want to make a circuit to collect the temperature of some locations in a control panel. I have a control panel that is connected to several microcontroller circuits. Each microcontroller circuit measures its ambient temperature. the control panel sends a number from 1 to 20 for example...

I have Setup like this for my application. I have Transformer which gives out 12V 1A & 5V 500mA output.I have used isolated ADM2483 design where power galvanized isolated. Primary side 5v &gnd taken from 7805 regulator where 12v input comes from transformer. same ground used by MCU/ADM2483 side...

Dear all I have used PIC18F45k40 device for RS485 communication. I have 2 ckts one is isolated and another non isolated RS485 design. I have schematic & placement for reference. I have connected multiple slave device independently isolated and non isolated product , its working well. There is...
