Expansion Bus LED and Port

Use the Expansion Bus port to connect an EXP1 Expansion Bus device to the HAL1 via a FireWire cable. To attach additional Expansion Bus devices to your HAL System, use a FireWire cable to connect each new device to the previous device—in a daisy chain style.

If lit, the Expansion Bus Link LED indicates that the Expansion Bus device is communicating properly with HAL. If an Expansion Bus device is properly connected to the port yet the status LED remains dark, there is likely a problem with the connection.
