# Hardware Back Panel

The Omnia XII back panel provides six dedicated sections that support network, I/O, and clock connections. The I/O connectors support digital (AES/EBU I/O), analog, and composite I/O. The network connectors support remote control of the unit, plus Livewire+ AES67, linear MPX over IP, and optional µMPX encoding. The top section of the back panel includes two power supply connectors.

Omnia XII back panel

#### Top Section

- **Model #** (Sticker): The model number of your unit.
- **Serial #** (Sticker)**:** Serial number formatted as 0279xyyyy.
- **PSU2**/**PSU1:** Two AC power inlets for dual, independent, auto-ranging internal power supplies that provide power backup.

#### Network Section

The network connectors are RJ45 auto-sense connectors.

**NET 1 (RJ45):** Auto-sense AoIP interface for carrying Telos Alliance Livewire streams or AES67 audio streams in support of SMPTE ST 2110-30. The connector can also be used for TCP/IP based remote control of the unit.

**NET 2 (RJ45):** Auto-sense, used for TCP/IP based remote control of the unit.

**NET 3 (RJ45):** Auto-sense, used for TCP/IP based remote control of the unit.

#### AES/EBU I/O Section

- **AES In and Out (****six RJ45s****):** AES I/O for three channels via respective I/O pairs (AES1 In/Out, AES2 In/Out, AES3 In/Out).
- **AES In and Out (four XLRs):** AES I/O for two channels via respective I/O pairs (AES1 In/Out, AES2 In/Out).

#### Clock Section

**PPS In:** Opto-isolated PPS port for remote triggering and third-party integration. The input supports pulse per second (10 MHz) signals for high-precision synchronization.

**GPS In:** Opto-isolated GPIO port for remote triggering and third-party integration. The input supports pulse per second (10 MHz) signals for high-precision synchronization.

#### I/O Section

- **USB:** USB-C port provided for factory support.

- **GPI/O (DB-15):** Five parallel inputs, 5-V TTL levels, active low. For future support of the standard Telos Alliance xNode wiring format.

#### Analog I/O Section

- **Left In and Right In (XLRs):** Stereo +4 dBu I/O.
- **In and Out (RJ45s):** Stereo +4 dBu I/O.

#### Composite I/O Section

- **Composite In and Out (four BNCs):** Composite I/O for two channels via respective I/O pairs (1 In/Out, 2 In/Out).
