Hi guys I'm currently working with a Binder Oven and at the moment I believe the oven's Rs422 interface is dameged but I need to find a valid way to test it. To communicate to this oven I am using a Startech 1 port Rs232/422/485 Over IP Adapter. The interface to the oven is Rs422, although the protocol used to communicate is Modbus. Researching Rs422 I found that is a differential bus having 4 lines to communicate. Rx+ Rx- Tx+ Tx- Now when I measure the voltage levels on the Star tech device I find that the Tx+ and Rx+ lines are +5V and the TX-/Rx- lines are 200mV. When I try measure the interface on the Binder Oven I find that there is no voltage at all on these lines? (Measuring using an oscilliscope and multi meter) My question is is there a valid way to test an RS-422 interface that is on a machine and not on a PC's communications port? I have searched all over online but I still havent found a valid test. Thank You. T2DJ.

Hi guys,

i'm currently looking for a labview driver for a binder oven.

I couldn't found a driver in the forum nor on the binder homepage.

Does anybody know a download for the binder driver?

Thank you

Thomas
