1 Description

The lasershow output board Net OEM allows the control of ILDA-compatible lasershow

projectors by use of different lasershow control software via network connection.

There is no need for installing cards into PC-slots and Notebooks can be used to playback

lasershows.

The network media allows data transfer over long distance.

The use of TCP/IP-protocol allows the use of standard network hardware, like hubs, switches

and routers.

The board has an ILDA standard connector with symmetrical outputs for scanners.

The Net-19 features the Net OEM board in a plug and play 19 inch rack.

Net-19 is a Net OEM installed in a 19 inch rack, wired ready to use. Some parts of this manual (like

the wiring) will naturally not apply the Net-19 version, these sections are in italics.

Important Note:

Net OEM supports one output channel for one laserprojector.

Multiple projectors can be connected to one Net OEM parallel and will output the same content.

If multiple projectors should output different content (channels) of a lasershow, more cards are

necessary, one for each different channel.

2 First setting up

Use regulated voltage only.

Net OEM works at power supply voltage between 8 and 14 V DC.

It is recommended to use stable power supplies, resistant against noise and interference

on the mains power. If possible, use additional line filters.

Net-19: connect to mains.

For reliable operation, a high quality CAT5 cable should be used for network data transmission.

Bad cables can influence output quality by increased number of lost data packages.

When using wireless network, it should be taken into account, that the RF-signal strength is good

enough and that other transmitters next to the setup can disturb data transmission.

When doing public shows, cable connection should be used instead of wireless network for safety

reasons.

CAUTION!

Never mount or remove the add-on board (ILDA board) while Net OEM is switched on!

Also be sure that the add-on board is placed completely in the socket and is secured with screws.

Otherwise the main board could be damaged and may be not reparable.

For lasershow control, all cards should work together in an own separate network and not together

with other clients, which can limit available data bandwidth.

If other clients (PCs or non-laser network devices) send requests to the same network, lasershow

output can be interrupted.

Each device will be shipped with a CD-ROM, which contains manual, drivers and test tools.

Important Note:

If multiple Net OEM cards are operated in a network, care must be taken that

all cards are supplied with the same actual firmware version. If cards with

different versions are connected to the network, malfunction will be the result.

2.1 Operating conditions

When the device is used as open board version (OEM), it should be taken into account, that the

device is sensitive object. Static discharge and other external influence can damage electronic

components on the board.

The device can also be damaged by applying external voltage to signal pins, by wrong connections

and other kind of manipulation. Watch for correct connection of signals and careful handling.

The device operates at very low internal voltage of 3,3V and 1,2V.

Overvoltage can destroy sensitive parts very quick.

The manufacturer excludes liability in case of damages as result of improper handling, wrong signal

connection and unspecified working conditions, unless it is verifiable that damage existed when the

product left factory.

Also any liability claims regarding damage caused by the use of this product will be rejected.

2.2 Setting up Net OEM step by step (manual IP-address)

The host PC must be supplied with a 100MBit network adaptor (100BASE-TX) or faster.

When working with wireless LAN, a wireless access point is required. The minimum data transfer

speed should be 54MBits/sec.

Net OEM is factory side set to the manual IP-address 192.168.0.100 at the DIP-switch.

Connect Net OEM to the network cable and switch on power supply.

Standard CAT5 patch cables can be used as well as cross over cables. Net OEM recognizes the

cable configuration automatically (Auto MDI/MDIX).

First setup the network connection at the host-PC.

Select 'Start'->'Setup'->'Network connections'

All available network connections will be displayed.

Select the properties of your connection for your LAN adaptor (here: LAN-Verbindung) by clicking

the right mouse button.

If there isn't any connection available, select 'create new connection' or 'create new network'.

Select 'Internet protocol(TCP/IP)' and click on 'Properties'

Activate 'use following IP-address', not 'get IP-address automatically'!

For first setting up, AutoIP/DHCP mode should not be used.

Type in the IP-address of the PC, for example 192.168.0. plus a value smaller than 100 or greater

than 115.

The first 2 numbers 192.168 are set unchangeable in the manual IP mode of Net OEM.

The third number (subnet) can be 0 or 1. This can be set at the DIP-switch of Net OEM.

The fourth number (device address) can be between 100 and 115. This value may not be set at the

PC, otherwise no communication could be possible.

As subnet mask use 255.255.255.0.

The values 'standard gateway' and the DNS-server addresses are not necessary.

Important: The manual IP-address of Net OEM (DIP-Switch) will be loaded by the card at power-

on only. So it must be set before switching on Net OEM!

Be sure the same subnet address 0 or 1 (third number of IP) is set at Net OEM and the PC.

Otherwise, no connection is possible.

2.3 Connection test

To check if a network connection is established between Net OEM and the host PC, start your web

browser and type in the IP-number of Net OEM in the web address field.

A startup page should be displayed now. This page contains some information about the network

address, MAC-address and firmware version of Net OEM.

If no start page is displayed or if no web browser is available, you can also check the connection

using the command line level.

Type in ping 192.168.0(or1). plus the card address 100 to 115 and press <Return>:

An answer should be displayed now.

If a timeout message is displayed, the correct settings of the IP-address of both, Net OEM (DIP-

switch) and the host PC must be checked again. Check the cable connection also.

Some PCs or Notebooks have problems with direct peer-to-peer network connections.

If no connection is possible, try to connect a network switch between host PC and Net OEM.

It can take some seconds until connected devices are recognized by the host.

Wait some seconds after connecting the network cable (or switching on Net OEM), before checking

the connection.

2.4 MAC-address and ARP-Cache

The MAC-address is a device number for each network device. It is a worldwide unique number.

Each network device has a different number. This number cannot be changed.

The host PC stores a list of corresponding MAC-numbers and IP-addresses after a device is

connected. This list is the so called 'ARP-cache'. This list can remain in the cache until the next

booting sequence of the PC or even longer.

When setting Net OEM to a new IP-address, there may be stored the old address in the cache so that

the PC cannot find the device under the new address.

It can take some time (up to a few minutes) until the PC refreshes the cache.

So if no connection is possible after changing an IP-address of Net OEM, there are 2 possibilities to

solve the problem.

1. disconnect and reconnect the network cable.

2. delete the old ARP-cache at command line level by use of the following command:

arp -d 192.169.0(or1). and the device address 100 to 115 <Return>

There is no answer to the command, except if no entry was found in the cache.

The card should be found now from the host again.

2.5 Using the internal IP-address of Net OEM

Alternative to the manual IP-address via DIP-switch, a second IP-address can bet set.

This address is not limited to the address 192.168.x.x and is set using the web interface under the

menu 'Network Settings'.

Important:

This IP-address becomes valid only, if DIP-switch number 9 is switched off and if IP configuration

in the web interface is set to 'manual'.

If the switch number 9 is set on, the IP-address set at the DIP-switch is taken.

2.6 Using AutoIP / DHCP /UpnP

If your network is configured automatically. you can activate the automatic mode of Net OEM.

The internal mode (IP-address) of Net OEM is configured as DHCP/Auto-IP mode.

If you switch the DIP-switch number 9 to OFF, automatic mode is activated.

If the internal IP-address of Net OEM is set to manual mode, you have to change it to automatic.

To get access to the web server of Net OEM, you have to start with manual IP, go into the network

settings via web interface, change the mode to automatic and click 'apply'.

Net OEM has to be restarted now.

Net OEM now can establish connection to the host automatically.

Because now, the IP-address used by Net OEM is unknown, UPnP is used to allow the access to the

web server without knowing the actual IP-address.

Automatic mode without use of UPnP

1. Set all DIP-switches to OFF (upper position)

2. Set network settings of the host to automatic.
