In the field it can be advantageous to flash an i2 to a b3 or a b3 to an i2
flashing controllers in the field can save time
1. If the controllers are i28xx-V or b38xx-V then these can be flashed back and forth in the field.
2. If the controller are NOT i28xx-V or b38xx-V (any other type of controller) then it cannot be flashed in the field, it will need to be sent to repair to change from an infinet to bacnet or bacnet to infinet. If you attempt to flash this way in the field it can cause the controller to become a brick.
