I looked at the Link given to the model that is being used here and it does not show it having Ethernet. Just because it has a jack on it does not mean it has it. The model pointed has a X marked for Ethernet but does have RS-485 which means a converter is needed from the PC to the device for 485 since those are balanced lines. Now I suppose it could be configured for 232 single end.. It would also be nice if any research was done to indicate the device supporting MODBUS to start with? It could be a simple ASCII unit generating lines of text etc...In any case, the PC/LapTop most likely needs to have a static IP, if Ethernet is really supported and that IP can not patch the device.
Where can i specify this Slave ID for Lazarus IDE?
