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.
Page 6: Hardware Installation
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.
Page 7 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.
Page 8 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.

ESMONITOR SOFTAWRE ESmonitor Softawre Please refer to AUVITRAN “AVS-ESMonitor USER MANUAL” that can be downloaded on 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…).
Page 10: Virtual Nx242 Tdcontroller Direct Access
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.
Page 11: Info Box
NX242 REMOTE CONTROL PAGE Analogue IN Two analogue input channels (A&B) and two digital inputs channel (corresponding to the ES routing) are visible. The headroom setting allows the scaling of the analogue signals before the AD converter. In an analogue- analogue mode this setting does not affect the overall gain (the inverse gain is performed after the DA conversion).
Page 12: Output Box
NX242 REMOTE CONTROL PAGE OUTPUT box From top to bottom Channel label: This duplicate the channel name displayed in the NX242 Interchannel Gain: range from –6 to +6dB in step of 0.5dB. The value of the gain can be entered directly in the text box. Bargraph: Represents the output level in dBu (absolute).
Page 13: Master Box
NX242 REMOTE CONTROL PAGE MASTER box This part of the GUI provides information and global control settings. Global Gain(Master): From –6 to 6dB in 0.5dB step. Gain can be typed into text box, or the slider can be moved with the mouse. Global Mute: Mutes all channels.
Page 14: Save/Recall Box
NX242 REMOTE CONTROL PAGE Save/recall box The Save and recall buttons store NX242 memory parameters. (This allows them to be recalled without PC control.) Group Creating, removing groups Group management is achieved by right clicking in the Group view window (in the left frame) and selecting the desired menu function.
Page 15 NX242 REMOTE CONTROL PAGE the command (in both the group view and individual view). Remember that changing this command again, in Group view, will reset according to the group value. The universal group mode view shows always the maximum value within all NX242 grouped (i : maximum bar graph, max delay, etc.…).
Page 16: Building Ethersound Networks
BUILDING ETHERSOUND NETWORKS Building EtherSound Networks Large segments of this chapter are taken from “building ES Networks V1.0”. (Courtesy of DIGIGRAM) Preface EtherSound uses standardized and well-proven technology from the world of digital networks, in order to cost-effectively convey high-quality audio. The EtherSound protocol provides fully deterministic, very low-latency transmission of synchronized audio channels over standard Ethernet.
Page 17: Ethersound Network Topologies
BUILDING ETHERSOUND NETWORKS Analog and digital filters ensure clock recovery and a minimum of jitter. Nevertheless, network equipment can introduce jitter that inhibits filter operation and sample extraction from the EtherSound frame, causes sample loss and degrades audio performance. EtherSound network topologies EtherSound devices may be daisy chained or use a Star architecture (in this case switches must be used), or a combination of both.
Page 18: Ethernet Additionnal Hardware
BUILDING ETHERSOUND NETWORKS Mixed Daisy Chain & Star Configuration Ethernet Additionnal hardware Hubs A hub (also known as repeater) is a central connection point for computers on a star- topology-based network. Any data it receives is broadcasted to all ports, and then only the computer that is ‘listening’...
Page 19 BUILDING ETHERSOUND NETWORKS forwards data between network devices. Unlike a standard repeater hub, a switch is able to read the destination address of each frame and then forward it to the correct port. This ‘intelligence’ in the switch means that a device receives only those frames addressed to it.
Page 20: Ethernet Cables
BUILDING ETHERSOUND NETWORKS ETHERNET CABLES Cables used within the EtherSound network are straight cables. The cable used to connect the PC to the primary master is a crossover cable The following paragraphs describe the main cable types used. Among them, you will find descriptions of cables listed for reasons of completeness, but that are not suited for EtherSound networks.
Page 21 BUILDING ETHERSOUND NETWORKS Horizontal cable (also called solid cable) is made of plain copper conductors and has a low characteristics shift with aging. It must be used for long runs of steady cabling (typically the cables inside walls and ceiling). Patch cable (also called stranded cable), more flexible, is made of stranded copper conductors and has larger losses and characteristics shifts than horizontal cable.
Page 22: Ethernet Connectors
To use Fiber Optic cable in EtherSound networks, Media Converters must be used. ETHERNET CONNECTORS The Ethernet connector equipping your cable shall ensure a good metallic coupling with the metal box of the NX242 digital TDcontroller. NEXO recommends NEUTRIK ETHERCON connectors. NXTENSION USER MANUAL...
