If the procedure does not work and the serial timeout error is issued again in the DCS Error Dashboard and the magnet cannot be controlled by the magterminal something HW is happening.

diagnosis
The DCS Element dashboard shows if there is some moxa involved in the connection. If this is the case a check of the full SW/HW stack must be performed:.
Until the diagnosis is not complete or the moxa is not accessible DONT RESTART THE MOXA.
- check the integrity of the cabling from the port of the moxa (found in DCS Element dashboard ) to the magnet interface.
- With the devil running check if the TX led of the port is blinking (the devil tries to access the hw).
- If not, you must check if the devil is running and Moxa serial lines documentation is aligned with the DCS Element dashboard.
- access to the Moxa web interface (login info) and navigate in Monitor→async and look the debug information of the relative port (see the picture below). Here there are the byte sent by the devil (TX) and by magnet (RX). If the communication between the devil and the moxa is ok the TX number should increase as well . Then if the communication between the magnet and the moxa is ok should the RX should increase as well. Remember the page is refreshed each time a click on 'Async' is performed. Each time the RX/TX led blinks the counter should increase.
- If the RX led of the corresponding port is not blinking means that no data are coming from magnet
- To quickly test if the full stack HW/SW till the magnet magnet use a loopback cap (il tappo) that connects TX with RX. You should observe TX/RX blinking and the counters of the moxa interface increasing. If this is the case means the serial interface of the magnet must be repaired or replaced. Otherwise there is some misconfiguration that requires further investigations.
