ASTDan Posted March 18, 2008 Report Share Posted March 18, 2008 Hello, Does anyone know if I can hook up 2 computers to monitor a single RS485 device? I can set my device to continously send out data. So the computers don't need to send data to the device they just need to receive it. Will I run into loading, or ground loop issues, etc.? Thanks Dan Quote Link to comment

You can hook PCs together on one RS485 network. Think of it as a networked version of RS232. QUOTE (ASTDan @ Mar 17 2008, 04:37 PM) I can set my device to continously send out data.

Loading will depend on the rate that the device sends out data. Ground loops should not occur so long as you hook everything up per RS485 specification. Line loading won't occur unless you exceed the RS485 specification (seems like it's 32 devices on no more than 1000 feet, but I'd have to look it up). Quote Link to comment
