Has anyone ever used the Niles A4.6 system with an Escient Fireball successfully? I have done several of the A4.6 systems, and are very familiar with them. The Fireball is in another room, with the i/r flasher running over cat5. There is also an Intellicontrol at the location of the Fireball, it is synced with the A4.6 since the Fireball is shared for both systems. The i/r goes from the Intellicontrol, to the 4.6 then back to the Fireball and works everytime. But the keypads in the house just don't work consistently, except if I control it from my pc connected to the A4.6. Thanks for any advice.
