The device is made by DIP (dipinc.com)and the part# is PFB366. I am using a PC with a Synergetics CIF30 Profibus master card and Sycon configuration software. I currently have no control software. All I want to do is be able to send the barcode reader a single character to either start a trigger or stop a trigger. Any ideas? I can use the I/O monitor to view the reads succesfully but I cant get what I write to the device to transmit to the reader.

 

Hello.
Maybe what you need is supply by Trebing&Himstedt and Phoenix Contacts: is a small RS232 to RS485 converter with drivers for use in a Profibus Network.
Try to visit their web pages for more detailed informations.
