Is the Powerbar6D broken?

[denzil]

Hello,

I'm helping configure a friend's 3 eX and it seems that when activating manual override on the Powerbar6D-PAB that's connected to the PAB is connected to the 3 eX which is then being manipulated via PC using the GHL Control Center. When I set things to "Always on" manually, I don't see any of the switch lights turn on. The only light that remains on is the Pwr light and the Com light continuously blinks.

Any insight if I may be doing something wrong or is the Powerbar6D-PAB just broken? I've already tried using both PAB ports on the EX3 and the Powerbar6D-PAB.

For reference, the 3 eX has v6.08 BETA firmware and the Powerbar6D-PAB has v1.08, or at least I think I uploaded it successfully since I see the Com light flicker throughout the update process. These firmwares should be compatible with each other, correct? However, when I go to the System page in the GHL Control Center, all I see is the ProfiLux 3 eX and its serial connection and not the Powerbar6D-PAB.
