Nº502 Media Console Appendix
Link2
The main purpose of Link2 is to allow a single “master” device to control
specific functions of other Link2-capable Mark Levinson products.
In order to use Link2, the following conditions must be met:
• Link2 support is only available for the Mark Levinson Nº502 Media
Console and the Nº400-series Power Amplifiers.
• All products must have Link2 communication ports.
Refer to the product documentation of each Mark Levinson product to
verify compatibility and cabling requirements.
To use Link2, all devices are daisy-chained together using Cat. 5 Ethernet
cables, as demonstrated in the figure on the left. Each “chain” can have
only one “Master” device; all other devices in the chain become “Slaves”.
Slave devices receive and respond to the commands of the Master device.
The Link2 protocol can support a maximum of one Master and eight
Slaves in a chain. The Nº502 Media Console can only be used as a Master
device. The power amplifiers must be Slave devices.
Ensure that all components are powered Off before connecting the Link2 ports.
Once connected, power on the linked components one at a time to
ensure proper functioning of the Link2 controls. The Nº502 Media
Console must be powered on first.
Allow each component to complete the initialization sequence before
proceeding to the next component. Once all components are powered on,
verify that the front panel Standby LEDs on the linked components are
blinking in unison.
The Nº502 can perform the following Link2 functions:
• Synchronized LEDs – the Standby LEDS of the Nº502 and all linked
amplifiers should blink in unison.
• Standby Link – the state of the Nº502 Standby mode is replicated by
all linked amplifiers. When the Nº502 is taken out of Standby mode,
the amplifiers should also come out of Standby mode. Likewise, when
the Nº502 is put into Standby mode, the amplifiers should also go
into Standby mode.
• Fault Condition Reporting – if a linked power amplifier
experiences a fault condition, it’s reported on the Nº502. If this
occurs, the power amplifier number and the fault condition code are
displayed. The power amplifier number refers to its position in the
chain. For example, AMP1 refers to the first amplifier in the chain.
Refer to the product manual of the amplifier for a description of the
fault condition code.
