Hi, this is my first post, but I have made several Gadgeteer Apps that deploy/debug over USB. I want to use USB to communicate with a PC using CRC, so I am trying to swap the deploy/debug to Serial (RS485). I have created a simple FEZ Spider setup to test this. What am I doing wrong? Am I missing something obvious like a DIP switch?
# Setup #
FEZ Spider Mainboard
- USB Client SP (socket 1)
- RS485 Module (socket 11, connected to the PC using a Moxa UPort 1130 in RS485, 2wire mode)

# Confirmed #
I can deploy over USB.
I can communicate over RS485 while deployed over USB.

# Issue #
I cannot deploy over RS485.
Error: “Unable to communicate with device Serial:COM8”

Note: The PC appears to be transmitting while deploying because the TX LED flashes on the Moxa when deploying over “Serial”
