With a 140 CRA 31200 SV1.09 or 1.20, you cannot upgrade the CRA in the normal user mode.
But you can do it in the "Stored" mode.
The procedure is the same as for an unconfigured BMXCRA31210, BMXCRA31200 or BMECRA31210 :

• Set the rotary switches of the CRA to "stored"
• Power cycle the 140CRA31200
• plug on the CRA's service port
• Set the IP adress of the PC on the network 10.10.xx.yy
• Use the 10.10.mac5.mac6 @ on UnityLoader
