Section 11: THE WORKS – Detailed Menu Reference 237
SYSTEM - Menus 8 & 9
PP Out 0 to PP Out 7
SYSTEM Menus 8 & 9 determine the function for each of the eight outputs of the serial port.
The option for reach output can be separately set to any of the following values. For more
information on the Parallel port hardware interface see Sections 3.2 (Guided Tour of the
Hardware ‐ Non Mixer Version) and Section 3.3 (Guide Tour of the Hardware MX/P).
For more information on Livewire GPIO and how it applies to the Xstream’s parallel ports, please
see Section 8: LIVEWIRE – IP Audio.
ON
Forces this output to the "true" state. This will cause the input to sink current
thereby activating an external device. This mode is intended for
troubleshooting.
OFF
Forces this output to the "false" state. Input will become high impedance with
regards to ground and will "float" to 5 volts due to the built in pull up resistor.
This mode is intended for troubleshooting.
Mixer On (MX and MXP only)
Causes this output to go the "true" state whenever one of the front‐panel mixer
inputs is assigned to A, B or Both channels. This can be connected to a local
"on‐air" signal or can be connected to an input to pass this indication to the far
end.
1 AND 2 Conn
Causes this output to go the "true" state whenever both Line 1 and Line 2 are in
the "Connected" state (as indicated on the first TEL menu).
1 OR 2 Conn
Causes this output to go the "true" state whenever either Line 1 or Line 2 or
both are in the "Connected" state (as indicated on the first TEL menu).
Line 2 Conn
Causes this output to go the "true" state whenever Line 1 is in the "Connected"
state (as indicated on the first TEL menu).
