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

4
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.

6
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

7
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>:

8
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.

9
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.

10
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.

11
3. Connect Net OEM to the network.
It can take several minutes until the connection is established.
In some cases, Windows will announce a limited connection. This will not influence
operation of Net OEM.
Net OEM now should be recognized by the host application.
To access Net OEM via web browser, UPnP is required.
UPnP is part of Windows, but may be deactivated under Windows XP SP2.
The following chapter describes how to activate UPnP under Windows XP if the connection to Net
OEM is not already visible in 'my network places'.

12
2.6.1 Activating UPnP under Windows XP SP2
Open 'Network and internal connections' in the control panel of Windows.
Click 'Network connections'.
If UpNp is activated, you should already see an icon of the connection to Net OEM.
If this is not available, you should verify that the correct components and services are loaded in
Windows XP. Open the 'Add/Remove Programs'control panel, and then click on 'Add/Remove
Windows Components' in the sidebar. Scroll down and find 'Networking Services', highlight it, and
then click 'Details'.
In the Networking Services window, ensure that the 'Internet Gateway Device and UPnP User
Interface' options are checked. If they are not, check them to enable them, as shown below, and then
close out back to the control panel.
To ensure that the connections are visible in 'my network places', activate this under 'Network tasks'
at the left side of 'my networked places' by clicking 'Show icons for networked UPnP devices'

13
Also enable the firewall exceptions for UPnP in the firewall settings.

14
If UPnP is activated and Net OEM is connected in automatic mode, you should see an entry in 'my
networked places'.
By double click to the entry the web browser directly will open Net OEM.
By right click to the entry, you can directly read the actual used IP-address, if required.

15
2.6.2 Alternative access to Net OEM via web browser
Here is an alternative method to access the web interface of Net OEM in automatic mode, for
example if UPnP does not work on your system.
Open the command line in Windows and type
arp /a
You now get a list of all connected devices.
If more devices are connected, you can identify Net OEM by the MAC-address.
This address is printed on a label on each Net OEM card.
If you don't know the MAC-address of Net OEM, you have to try all shown IPs.
Type the IP-address in your web browser.
If the right IP is selected, the start up page of Net OEM opens.
Important: After adding or removing network devices, the dynamic IP-address may be changed.
If no more access to Net OEM is possible, check the address entry again in command line mode.

3 Signal connections and controls
3.1 Board layout
3.2 Setup of manual IP-Address (DIP-Switch)
This manual IP-address is valid if DIP-switch number 9 is ON (down position).
Switch number 1 tells the subnet number 0 or 1 (the third number of the IP-address).
The first 2 numbers of the IP-address are fixed to 192.168.
The device address (last number of the IP-address) can be selected by 4 DIP-switches number
2 to 5. The set value in binary mode (0 to 15) will be added to the value of 100.
Switch number 2 has the value 8, number 3 the value of 4, number 4 the value of 2 and number 5
the value of 1. To set the address to 192.168.0.101, switch number 5 is set of ON, all others are set
to OFF (except of switch 9, which sets Net OEM to manual IP via DIP-switch).
A value of zero at the switches means address 100. If all 4 switches (2-5) are ON, the device
address is 115.
The range of the IP-address via DIP switch is 192.168.0.100 to 192.168.0.115 or 192.168.1.100 to
192.168.1.115.
3.3 Test pattern output
Switch 7 allows the output of a test pattern.
To activate test pattern output, this switch must be set to ON before switching on Net OEM.
This function is to check the connection from Net OEM to the laser device (ILDA connector).

17
3.4 Connections of scanner an colour signals
All signal outputs for the laser projector are located at a 26 pin connector.
The connector is located at the add on-board (slave board) of Net OEM.
When using a flat cable between this connector and a 25pin DSUB connector, all signal numbers
are compatible with the ILDA standard connector.
Note: The 26pin connector has a different pin numbering compared with the 25pin DSUB-
connector (see table).
The outputs X and Y are symmetrical. The signal amplitude is given by the difference between the
positive and the negative signal pin.
The colour signals and intensity are unsymmetrical (referenced to GND).

5 ILDA-Player
5.1 Function
Net OEM comes with a standalone player for ILDA files.
The player allows playback of show sequences stored on internal SD-card by control via DMX or
directly from the web interface.
Shows or sequences must be stored in ILDA-format (format 0, 1, 2, 4 or 5).
Configuration of the player as well as file upload is done in the web interface.
5.2 Show management
By clicking on 'Show management' under the menu item 'player' of the start page of the web
interface, all stored shows can be listed.

20
The table lists all ILDA files stored under the SD-cards 'player' directory.
New files can be uploaded.
Note: Upload via HTTP is very slow (about 150KBytes/sec.).
Long files >1MB can take several minutes for upload.
Avoid the use of very long files. 10MB can take about 10 minutes!
After uploading, the new file will be listed in the show table.
To delete shows from the card, select the show at the 'delete' selector and click 'Apply'.
For each show file, several parameters are listed in the table:
DMX Value
The first field normally is empty.
This field will contain the number (DMX-value) under which the sequence can be started via DMX
control.
Note: The value is equal to the fader value for show selection.
To make control via fader more easy, 2 different DMX channels are used for show selection, each
one for 16 numbers. Both channels are multiplied, so total 256 sequences can be selected via DMX.
See DMX-Settings also.
Number (value) 0 should not be used, because fader position 0 of the DMX control desk should
stop show output.
Output Speed PPS
The speed cannot be controlled via DMX signals for safety reasons.
The default value for all sequences is set to 10Kpps.
The user must test the correct output speed for individual sequences.
Each sequence can be started directly in the web interface by selecting the corresponding 'show'
selector in the table (not 'delete'!) and clicking 'Apply'.
For output of the sequence, settings in 'speed PPS' and 'Framerepeat' are used.
This direct show start can be used to check the right output parameters.
To stop output, click 'Stop'.
Note: If the sequence in the table is not set to a DMX start number (first field), some parameters are
reset to their default values after starting the sequence, for example output speed PPS.
To save the parameters, the sequence must have a DMX start value.
Frame Repeat
The number of repetitions of each frame of the sequence during playback.
By using this parameter, the speed of the animation can be controlled.
Frame Repeat can also be controlled via DMX.
