As of mid-2015, the E46 replaced the D46, and the D46 is considered to be a legacy product.When the D46 pan tilt units were an active product, they were supplied with a PTU-D46 controller. These controllers are now end-of-life and have been replaced with the PTU-E46 controller. The pan tilt heads are still exactly the same.
Top level part numbers beginning with D46 have been replaced by the E46 equivalent. For example, a customer that previously purchased the D46-70-SS-000-SS would now need to purchase the E46-70-SS-000-SS.Additional features supported by the E46 include:
The only physical differences are the addition of the Ethernet connector and the location of the power connector, which has been moved to the other side of the controller box.
