The main difference between the V2 and V1 set of firmwares is that the V2 firmwares enable the Ethernet port on the unit. This makes the IC-W1 units WiFi as well as Ethernet capable.
The V2 firmwares are not compatible with the V1 units; therefore if you would like to convert your V1 unit into a V2 capable unit you must follow the steps below.
V2 units have a label "IC-W1 V2" on the right hand side of the unit. If your unit does not have this label or if your current firmware version starts with "IC-W1-1.2.xxxx" or lower then you own a V1 unit.
Unfortunately you cannot do this yourself but we provide a complimentary service for this conversion. There is no charge for the service; you would only have to cover for the shipping.
If you would like to convert your unit and make it V2 capable, you can send it to:
When we receive your unit we will convert it for you and ship it back. If you have your own shipping account you can send us a label; if not you can pay for shipping here:
