SpaceLogic C-Bus Commission v2.15.0 or higher supports the capability to program eDLT's with the following characteristic:

Hardware: v3.0
Firmware: v2.X

A firmware upgrade of an eDLT to v2.X can only be done in C-Bus Commission; however, the eDLT must support hardware v3.0.

Some key points to remember when performing a firmware upgrade using C-Bus Commission:

• In C-Bus Toolkit, you can only upgrade an eDLT’s firmware up to v1.8

• Once you upgrade the firmware to v2.X, you cannot revert to an earlier version

• A firmware upgrade to v2.X will factory reset the unit; the device will need to be re-programmed
