- Step-by-step fixGet the fix →
After updating to Hog 4 OS v4.0+, old show file behaves oddly / values or colors look wrong
Likely cause: The v4.0 color/data model changed; ETC intentionally broke show-file compatibility, so a v3 file cannot map 1:1 into v4.
- Step-by-step fixGet the fix →
Console can't find / isn't talking to external DP8000 DMX processor
Likely cause: Hog nodes discover each other over HogNet multicast on a shared subnet.
- Step-by-step fixGet the fix →
Console cannot be updated and HogNet port won't function; networking dead
Likely cause: A missing/corrupt MAC on the HogNet NIC prevents the adapter from initializing; it requires hardware/firmware service.
- Step-by-step fixGet the fix →
DP8000 outputs Art-Net/sACN but no physical DMX from the 5-pin ports right after updating the DP over the network
Likely cause: The over-network update path can fail to reload the DMX output-board firmware; a full reflash restores it.
- Step-by-step fixGet the fix →
Hog 4 PC / backup console won't connect to or fail over with a running Road Hog 4 show
Likely cause: Hog networking requires identical software versions and a common HogNet interface/subnet; a mismatched adapter or version blocks the session join and failover.
- Step-by-step fixGet the fix →
Internal or external touchscreen out of alignment / not registering touches in the right spot
Likely cause: The calibration tool maps touch coordinates to the display; a reboot commits it.

Need to remap/reassign which DMX ports feed which universes on Road Hog 4 / DP8000
Likely cause: The mappable-ports feature was added in v3.14.0; older show files predate the data structure and lock port order.
- Step-by-step fixGet the fix →
No DMX from a Hog widget/DP universe when running Hog 4 PC on Windows (widget mapped but dark)
Likely cause: A blocked/removed signed driver leaves the widget with no working USB driver; only a clean reinstall restores it.
- Step-by-step fixGet the fix →
Updating the Road Hog 4 OS / update fails or errors mid-install
Likely cause: A local USB install avoids network-update failures; leaving peripherals attached lets the installer enumerate and load their drivers in one pass.
