Upon diagnosing RTU 7 found prodigy board to be faulty. Temporarily bypassed board to keep unit cooling. Install new board and test for proper operation. Arrived on site checked in with brinco and mod. Proceeded to RTU 7 for the repairs. Removed and installed new prodigy board, configured the board to the unit. Had to call EMS to finish configuring the communication part of it. RTU is running no issues to report for now. Checked out with all parties.
