RESET button Pressing the RESET button causes the card and all connected audio devices to momentarily stop their current activity and to restart. The card’s “frame data” light goes off when the reset starts and comes back on when the reset is complete. During the reset, configuration information downloads to the card and its connected audio devices from the CPU card. If the entire system is operating except for one port card, or one or more panels connected to the card, press the reset button for that card only. Tip: The reset button is slightly recessed from the front panel to prevent it from being accidentally pressed. A tool such as a bent paper clip is required to press this button. |

Power supply lights +12-Volt and -12-Volt Power Supply Lights The matrix’s +12-volt and -12-volt power supplies provide electric current to these two green lights. When lit, these lights indicate that the matrix’s +12-volt and -12-volt power supplies are present and supplying electric current to the card. +5-Volt Power Supply Light The matrix’s +5-volt power supply provides electric current to this green light. When lit, the light indicates that the +5 supply is present and supplying electric current to the card. +3.3-Volt Power Supply Light The matrix’s +3.3-volt power supply provides electric current to this green light. When lit, the light indicates that the +3.3-volt supply is present and supplying electric current to the card. |

Active Lights When lit, an active light indicates successful communication between the port card and a connected device such as an intercom panel or interface. Each of the port card’s 16 yellow active lights corresponds to one of 16 rear-panel connectors or “ports” to which audio devices can be connected. |

|
VOX Lights When lit a VOX light indicates that the audio level on a connected device, such as an intercom panel or interface, has exceeded a preset threshold. The threshold audio level is set through the EHX application. Each of the port card’s 16 green VOX lights corresponds to one of 16 rear-panel connectors or “ports” to which audio devices (intercom panels or interfaces) can be connected. |

Frame Data Light The green frame data light flashes (1: 1 0.5Hz) to indicate successful communication between the port card and the CPU card. The red status light illuminates to indicate a failure in communication between the port card and the CPU card. |
