2.3.8 Ethernet ports/ Mode
The Stage Racer 2 offers 2 independent Gigabit Ethernet ports, which can either be isolated or connected
together through an internal switch. Setting is done in the web Gui.
- When they are isolated, they behave like two completely separate ports which enables to create totally
independent Peer to Peer connexions over the Stage racer 2 network.
- When the ports are connected, they can communicate with each other through an internal switch. Thus
allow to create a distributed switch along the Stage racer 2 network in a daisy chained manner.
Note: The extremity nodes of the daisy chain can be isolated or connected. If they are isolated the remaining
port can be used to create another separate network connexion.
Note1: The Dante board is available on port IP-1.
Note2: Port speed is 10/100/1000Mbs Autosense and support straight or crossed cables.
2.3.9 Admin port
The Stage Racer 2 is equipped with a dedicated admin port to access the web interface. Port speed is
10/100Mbs Autosense and support straight or crossed cables.
The IP of the machine can be found using the navigation buttons next to the LCD INFO screen.
Firefox browser is recommended for Gui usage.
2.3.10 Genlock/Composite VIDEO port
This port supports Composite PAL, SECAM & NTSC / Black Burst / Tri-level sync compatible is transmitted
thru the Stage Racer 2 via the G/L port.
In a Stage Racer 2 network, the G/L port is direction switchable and work as follows: when the Genlock port
direction is set to input on a particular unit, the direction of all the other Genlock ports of all units connected
to the network will automatically be set to output. Then genlock is distributed to all the machines over the
network.
Composite video is carefully processed with Minimal latency and high quality process with +/-3dB AGC
input, 2x over sampling and 10 bits digital filtering and transmission is provided for this signal.
Internally each machine extracts Video and Audio genlocked clocks for frame buffering purposes.
