Expansion Bus LED and Port

Use the Expansion Bus port to connect an Expansion Bus device (such as an EXP1x) to the HAL via a shielded CAT 5e cable. To attach additional Expansion Bus devices to your HAL System, use a shielded CAT 5e 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.
