Talked with the folks at Rowe the other day. Sounds like early April on the USB programming cables. Give us a call if you'd like to pre-order one.
AND... the dashboard software that will be used with the cable will permit *one circuit* to be programmed for 20Amps for devices like Stebel air horns. No change needed to the PDM60, it's all in the software.
Remember - you heard it here first.
