2: Operation Via the 8x8's Front Panel • 6

Version 2.0, February, 2007

To program the node’s IP address follow these steps:

Starting from the metering screen, press the

<SELECT> button once. The default IP address is

“0.0.0.0”, so unless the unit has previously been pro-

grammed, the screen will show “000.000.000.000”.

Press and hold the <ID> button for 4 seconds. A

blinking cursor will appear below the ﬁrst digit. Use

<SELECT> to change the digit indicated by the cur

sor (each press of this number will increment the dis

played digit by one).

Press the <ID> button to jump to the next digit. Use

<SELECT> to change the digit indicated by the cur

sor. Continue until all digits of the IP address have

been entered.

Once the changes are complete, press the <ID> but

ton repeatedly until no cursor is shown then press

<SELECT> to exit.

If you do not wish to save your changes do not press

<SELECT> after reaching the last digit. After ap-

proximately 10 seconds the display will return to

the meter screen and the previous settings will be

restored.

Checking the Livewire Node Name

With the meter screen displayed, press SELECT

twice. The name of this Livewire node will be displayed.

The default is LiveIO. To change the name of a node you

must use the Browser interface, see section 3 Advanced

Programming.

Checking the Livewire Node Software Version

With the meter screen displayed, press SELECT three

times. The software version will be will be displayed.

Programming the Node’s Streaming Mode

The streaming mode can be selected from the front

panel. The default mode is to have streaming disabled

(e.g. OFF), thereby allowing safe connection to a com

puter or LAN for programming. See the Introduction to

Livewire; System Design Reference & Primer manual

for more on streaming. The possible settings for stream

ing mode are shown here:

OFF – This disables both streaming of Livewire au

dio and Livewire clock packets. This setting is useful

when you wish to connect the unit to a non-Livewire

LAN or directly to a computer to conﬁgure the IP

address and other settings.

FAST – This enables Fast Stream generation and

also permits clock packet generation. This is the

typical setting for most Livewire audio network ap-

plications.

SLOW – This enables Slow Stream generation as

well as Livewire clock packets. This is the usually

setting for a Axia node used in conjunction with a

computer or other device where delay is unimport

ant.

SNAKE – The mode is appropriate for when two

Axia nodes are directly connected with a null Eth

ernet cable. This enables Livestreams and Livewire

clock packets only. SNAKE mode differs from fast

by disallowing local loopback capability in the node.

CUSTOM – This indicates that the Streaming Mode

parameters have been conﬁgured using the unit’s

web page interface.

To change the Streaming Mode from the front panel

follow these steps:

Press the <SELECT> button repeatedly until MODE

is displayed.

Press and hold the <ID> button until a cursor appears

under the current setting.

Press <SELECT> repeatedly until SNAKE is dis

played.

Press <ID> to conﬁrm your entry.

Programming the unit’s Transmit Base Channel

(TxBCH)

The Transmit Base Channel is the number assigned

to the ﬁrst of the eight streams to be transmitted by this

unit. If the Transmit Base Channel is set to 00101 then

the system’s eight streams would be on channel numbers

101 through 108. Non-contiguous numbering is possible,

however in that case they must be assigned using the

node’s browser user interface, see section 3 Advanced

Programming.
