3.12. Power supply
The AVB Tool comes with an external 12 V 2.0 A power supply with a locking connector (5.5 mm positive
polarity) and detachable power cord (C7).
Insert the connector fully with the lock tabs facing sideways, then gently turn 30 degrees clockwise to
secure the connector in place. Reverse this process to unlock and unplug the connector.
Do not push and turn the connector at the same time as this may damage the DC socket.
3.13. MADI Coaxial and SFP
The rear of the AVB Tool features coaxial and SFP MADI (AES10-2003) I/O.
Each input receives up to 64 audio channels.
Auto Input
(see Connecting Two Identical MADI Signals for
Redundancy) can be activated to treat both inputs as one.
The coaxial BNC connector accepts coaxial cables with 75
Ω
impedance.
The
"small form-factor pluggable"
connector (
SFP
) accepts 125 MBit/s transceivers with LC connectors
and multi-mode (MM) and single-mode (SM) cable support. These must be purchased separately (see
Accessories).
An SFP module has indicators to distinguish transmitter (
▼
) and receiver (
▲
). It can be inserted and
removed while the device is powered on (hot plugging). Any plugged in connector must be removed
before unlocking the SFP. Unlock and remove by pulling its integrated wire latch outward.
The wire latch of the SFP module is color coded. Black stands for the most common
multimode module, blue stands for single mode which allows longer distance
transmissions. It is possible, but not reliable to connect single mode transceivers with
multi mode transceivers. Avoid this by always confirming that connected devices match
the specification of the fiber optic cable.
On the device, the characteristics and state of the signal at either input can be inspected in the
The presence or loss of a signal at either port is indicated on the standby screen and main menu if
• the input port is selected as
clock master
, or
• its audio channels are routed in the
OUTPUT
section.
