kiahzero Level 1 Level 1

I'm having a bit of an odd issue.  I'm trying to connect my Scientific Atlanta Explorer 8300HD (DVR) to my Mac Mini (mid-2010).  The device isn't detected, which doesn't seem so odd, but here's where the trouble starts:

 

* I know it's not the DVR: It connects to my Macbook Pro (mid-2010) just fine.

* I know it's not the cable: I have two FireWire cables, both of which can connect the DVR to the Macbook Pro without an issue.

* I know it's not the Mac Mini: It can detect other FireWire devices, and I've taken it into the Apple Store and confirmed that the logic board is in proper working order.

 

Things I've tried:

* I've reinstalled OS X Lion as a clean install; the DVR still wasn't detected.

* I've removed all other peripherals; the DVR still wasn't detected.

 

I'm wondering if there might be relevant differences between the MacBook Pro and the Mac Mini that could cause the DVR not to be detected on the Mac Mini, even though all of the individual components work in other permutations?  Really, I'm just baffled, so any advice would be appreciated.


Mac mini, Mac OS X (10.7.3)

    Are the Mini & the MBP both running 10.7.3?

     

    Is this device Bus powered, or does it have it's own A/C power?

  • kiahzero Level 1 Level 1

    Both computers are running 10.7.3.  The MacBook Pro is running build 11D50b, and the Mac Mini is running build 11D50d.

     

    The device is a cable set-top box and has it's own A/C power.

    Quite mysterious, what does System Profiler>Hardware>Firewire report on the two Macs?

  • kiahzero Level 1 Level 1

    The Mac Mini shows only the bus:

    FireWire Bus:

      Maximum Speed: Up to 800 Mb/sec

     

     

    The MacBook Pro shows the device:

    FireWire Bus:

      Maximum Speed:          Up to 800 Mb/sec

    Firewire reset, usb reset…

     

    What brand/model enclosures are these?

     

    • Shut down the computer.
    • Disconnect all FireWire devices and all other cables, except the keyboard and mouse cable(s).
    • Disconnect the computer from the power outlet and wait for 3 to 5 minutes.
    • Plug the computer back in and turn it on.
    • Reconnect the FireWire device(s) (one at a time if there is more than one) and test. Test with each FireWire port if you have more than one.

    No luck. For good measure I tried a PRAM reset, also with no luck.

     

    I'm afraid I don't follow what you mean by what brand/model enclosures. I'm working with two computers: a mid-2010 Mac mini and a mid-2010 MacBook Pro 17" i7. The device I'm trying to connect is a Scientific Atlanta brand Explorer 8300HD.

    That was the info I needed, hanks.

     

    Might try a Reset...

     

    Press and hold both VOL+ and VOL- buttons on the front of the box, then press INFO.

     

    Then see what System Profiler says.

  • kiahzero Level 1 Level 1

    No change: System Profiler on the Mac Mini shows only the bus.  System Profiler on the MacBook Pro continues to show the device.

     

    I'm thinking I might try to boot up with Knoppix on both machines, see if it's detected on one and not the other.  That'd let me affirmatively establish that there's not something weird going on with the software on the Mac Mini that's preventing the FireWire connection from working.

    I suspect that DVR will ONLY put out to a DISPLAY via FireWire (not a computer) - which is unusual, but DVR's often are unusual with their FW ports. 

     

    I have a DVR that will only INPUT via FW from a camera (not a computer).

     

    Maybe your MacBook Pro "pretends" to be a display, better than your mini can??
