Kirk- Can you elaborate on what you need? I've got a wide variety of boards that use RS-422 or RS-485, from simple optical isolators to boards with various processing capabilities. Over the years many of them have been obsoleted or were designed for one-off jobs but the PCB house still has the art. If they can be used I'd be willing to contribute the designs. For example, a long time ago I did a board with a PIC16C74 processor and an RS-485 transceiver and a big jumper field for whatever other parts might be needed. The RS-485 transceiver can be jumpered to force it to transmit only, receiver only, or be under processor control. Anyway, please tell us more about what you need and I'll see if there's anything that fits.
