HAL SYSTEM DESIGN GUIDE NOTE: This Ethernet port contains auto-MDIX functionality, which means that you can use either a standard Ethernet cable or a crossover cable to connect to a computer or Ethernet switch. The autoMDIX functionality takes care of coordinating the proper connection between the devices. The Ethernet LAN LED flashes when HAL detects any Ethernet packets on the network. The Link LED indicates if the Ethernet network is connected. If HAL is connected to an Ethernet network but the Link LED is off, there is likely a problem with the connection. 4. Expansion Bus LED and CAT5e 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. 5. Digital Remote Device ports Use these ports to connect each DR to the HAL via a standard shielded CAT 5e (or better) cable. You must use a shielded Ethernet cable for this connection. If you need more DR connections than the number of DR ports that the HAL provides, you can use a RAD port to connect a DR. 6. Remote Audio Device ports Use these ports to connect each RAD to the HAL via a standard shielded CAT 5e (or better) cable. You must use a shielded Ethernet cable for this connection. If you need more RAD connections, you will need to connect an Expansion Unit with RAD ports (such as an EXP1) to your HAL device. You cannot connect a RAD to a DR port. 7. Digital Remote Device LEDs Provides information about the health of the shielded CAT 5e connection between each DR and HAL. The numbers correspond to the DR ports in the lower area of the rear panel. The Comm LED (on the top row) lights solidly if the DR's data communications pair is working properly. The Power LED (on the bottom row) lights solidly if HAL is supplying adequate power to the DR port. 8. Remote Audio Device LEDs Provides status information about the health of the shielded CAT 5e connection between each RAD and HAL. The numbers correspond to the RAD ports in the lower right corner of the rear panel. For example, the LEDs for number 1 provide information about the RAD connected on port 1. Each LED corresponds with one twisted pair within the shielded CAT 5e cable. If the twisted pair is functioning properly, the LED displays a solid green light when the HAL is programmed to expect the RAD model that is physically plugged in. When all cable pairs are working properly, but HAL is not yet programmed for the connected RAD model, all four LEDs flash red. Note that flashing red is a good thing: the cable's good - just program HAL and you're done. l Audio Rx LED-lights solidly if the HAL receive pair is working properly. l Audio Tx LED-lights solidly if the HAL transmit pair is working properly. l Comm LED-lights solidly if the RAD's data communications pair is working properly. l Power LED-lights solidly if HAL is supplying adequate power to the RAD port. 14
