KNOWN BUGS & SOFTWARE ISSUES (15 MAR 05)
Known bugs & software issues (15 mar 05)
The software that you are going to install is the result of two months of field
optimization. However it’s status is still a PRE-release status and it contains still some
minor bugs & features that have not been fixed yet (and which may be described as
working in the following pages).
Please check our website www.nexo-sa.com periodically for updates.
ESmonitor Software
The Input VU meters don’t indicate red when clipping. The orange zone of the vu-meter is
not at -12dB. but earlier. Amplifier clipping is not represented on output VU meter.
Changing setup: C&F key combination for accessing different cabinet families is not yet
implemented. The software will issue a warning that you are changing family instead.
Protection monitoring is not implemented.
Firmware update via the network is not implemented.
Global MUTE does not un-mute!
Restore default button does not work
Hard lock button does not work.
SAVE/RECALL function is not implemented.
We are sorry for any inconvenient the above list may cause. We are expecting to
solve those points in the very near future.
Note : THE ETHERSOUND DIGITAL OUTPUTS OF THE NX242 ARE
CURRENTLY DISABLED, AS PROPERLY CONFIGURED ETHERSOUND
AMPLIFIERS DO NOT YET EXIST.

FOREWORD
Foreword
This manual is intended to help you to install and operate the NXtension-ES4
Expander Board.
Please have a look the page devoted to NXtension-ES4 on NEXO website
http://www.nexo-
sa.com/asp/catalogue/products.asp?linkid=284&prodcode=NXtension-ES4 before
installing your product to check if the release enclosed in the enclosed CDROM is the
latest.
This product is intended for use with the NX242 digital TDcontroller. Do not try to
install it in an NX241 as damage could result.
NXtension-ES4 Expander Board at a glance:
o Double DSP resources & Setup memory of the NX242 TDcontrollers.
o Remote Control potentials via WLAN and Internet, 100% Ethernet and TCP/IP
compatible.
o NX242 TDcontroller full remote control including Input/Output meters & protection
monitoring
o 4x Digital audio inputs from 64 uncompressed channels of 24bit/48kHz of audio
transmission over Ethernet. (EtherSound protocol)
o 4x NX242's processed digital audio outputs to 64x uncompressed 24bit/48kHz
channels of audio transmission over Ethernet.
Unpacking
The NXtension Expander Board package should contain:
-the NXtension-ES4 Expander Board
-2x M3x4 screws for replacing blank panel (rear of the NX242)
-3x M3x5 screws for fastening the NXtension Expander Board in the NX242
-1x CD ROM containing this manual, the LOAD needed for updating the firmware
of the NX242 and the ESmonitor software to control the NX242
-this manual

HARDWARE INSTALLATION
Hardware Installation
The card contains sensitive electric components, which can be easily damaged by
static electricity, so the card should be left in its original packing until it is installed.
Before touching the card make sure that you discharge yourself of static electricity.
Ideally, you should wear a grounded anti-static wrist strap when servicing electronic
units. As a minimum, make sure your body is touching the metal frame of the NX242
before removing the NXtension-ES4 from its anti static package.
NOTE: the NXtension Expander Board with the EtherSound extension MUST only be
installed in a NX242 Digital TDcontroller.
1. Remove the top panel of the NX242 (11 screws)
2. Remove the blank panel located on the back panel (2 screws). DO NOT USE
THESE SCREWS WITH THE NXtension card, AS THEY ARE TOO LONG
AND WILL DAMAGE THE PCB.
3. Remove the 7 jumpers located on the header CN5001. The positions of the
jumpers are illustrated below, in case you need to remove the board and run
the NX242 without the expander board fitted.

HARDWARE INSTALLATION
4. Insert the NXtension Expander Board in the NX242 by sliding the upper left
corner of the NXtension Expander Board under the corner of the rear panel of
the NX242 back panel until there is enough room to place the upper right
corner inside the NX242. (Supposing that you are facing the front panel of the
NX242)

HARDWARE INSTALLATION
5. Align the NXtension Expander Board on the axis of the spacer ME0004,
ME0006 and ME0008, push gently to insert the board.
6. Screw the NXtension Expander Board into the spacers (3 screws M3x5). Use
the screws provided with the NXtension package.
7. Screw the rear panel of the NXtension Expander Board to the rear panel of
the NX242 (2 self taping screws M3x4). Use the screws provided with the
NXtension package.
8. Replace the top panel. Pay special attention to the screws above the
aluminum heat sink. Only apply a light torque to avoid damaging the thread in
the aluminum.
9. Update the NX242 firmware to allow the NXtension Expander Board to be
activated. Follow the standard updating instructions given in the NX242 user
manual (or documentation provided with the LOAD).

AUVITRAN website http://www.auvitran.com .
This contains any information about software installation and use. Specific information about
the NX242 control page is given below.
NX242 remote Control Page
The Graphical User Interface (GUI) is divided in to several boxes, containing
commands that are related together (INPUT, OUTPUT, INFO…).

NX242 REMOTE CONTROL PAGE
Virtual NX242 TDcontroller direct access
At the top of the GUI, a virtual NX242 front panel allows real-time control of all NX242
function(s). The screen (identically) emulates a real NX242 screen – every buttons is
functional and the jog wheel can be controlled by clicking on the left/right arrows.
INPUT box
A radio button selects between 4 digital inputs and 2 digital inputs plus 2x analogue
inputs. Dependent on this choice the Input box will differ slightly.
In both cases an “array EQ gain” is present. The value of the gain can be typed
directly into the text box.
Digital IN
The four input bar graphs display on a logarithmic scale
the input signal. 0dB is the digital full-scale value, where
the AD converter clips. When clipping occurs the whole
bar graph becomes red. –12dB zone is orange. The
dynamic of the bar graph is 96dB. Above the bar graph,
the EtherSound channel is displayed (also visible in the
routing tab of the ESmonitor).
Headroom settings have no meaning in digital IN and
are not present. (The goal of the headroom is to adjust
the Analogue Gain in drive the AD converter full scale)
