Description Value
IP address 192.168.1.90
Subnet mask 255.255.255.0
Default gateway 192.168.1.1

UDP port 1225
Username admin
Password admin
The projector is shipped with a set of default settings, these are as follows:
Before you connect the projector to your LAN make sure that the IP address 192.168.1.90
is not already in use. If you need to change it, you have to make sure that the computer you
use is on the same subnet. This means that the computer need to have an IP address in
the range from 192.168.1.1 to 192.168.1.254.
2 SETTING UP LAN COMMUNICATION
2.1 Setting the IP address
If you need to change the computers IP address, follow these steps:
1. Right click on “Network Neighborhood” / “My Network Places” on your computer, and
then select “Properties”.
2. Doubleclick on the network connection that represents your LAN, select “properties”,
then doubleclick “Internet Protocol (TCP/IP).
3. This will take you to a screen where you can set the computers IP address:
Set the IP address and click OK on this and the previous dialog when you’re done.

2.2 Connecting to the projector
You have two options regarding how to make the physical connection to the projector.
You can either use a crossover twisted pair (TP) cabel directly from the computer to the
projector, or two straight-through TP cables with a HUB or a switch between them.
Now the computer should be on the same subnet as the projector, and you are ready to
configure it. This is done by starting up an internet browser, like Internet Explorer, Opera,
Firefox or similar. Then type the projectors default IP address (192.168.1.90) in the address
bar.
You will then be presented with the login screen shown below:
Type in the projectors default login name (admin) and password (admin), both are case
sensitive.
If both are correct, you will se a configuration website like this:
On this page you can setup the projectors IP address, subnet mask, default gateway,
projector port (TCP), rimi port (UDP), and password. This page also displays the current
version of network firmware the projector is running.

Other network options:
As you can see from the default settings table, the projectors also support commands over
the UDP protocol. HyperTerminal doesn’t support UDP but there are other applications like
the ones from SimpleComTools.
There is also quite easy to integrate this functionality if you are designing an application
yourself.
With a Crestron, AMX and other control system you now have the option to control the
projector via Ethernet in addition to RS232 using the same command set.
Once the projector is setup correctly and connected to the LAN, it’s ready to receive
commands. The LAN commands is exactly the same as for RS232 control, although you
may have to pass on the commands to the projector with a different application.
HyperTerminal that comes with Windows, can be used for this.
3 HOW TO USE THE PROJECTORS LAN FUNCTIONALITY
- Start up HyperTerminal, click ”File” and
then ”New Connection”. Give it a name
and press OK. You will then see this dia-
log, here you choose TCP/IP (Winsock).
- Now type in the projectors IP address in
the ”Host address:” field, and the projec-
tors TCP port in the ”Port number:” field.
Press OK when you’re done.
To send an eOperation to the projector, select
”Transfer” and then ”Send Text File...”.
You will then be presented with a dialog which you can choose the file you want to trans-
fer. Choose your command, click ”Open”, and the command will be transfered.

4 ESTABLISH COMMUNICATION
The projector may be controlled either through the LAN or the RS232 interfaces. Both
interfaces can not be used at the same time. Select between LAN or RS232 control in the
menus system (se the projector user guide for further information).
4.1 Connect to the projector
Connect the projector and host using a standard serial cable with 9-pin female to the host,
and 9-pin male to the projector. Pin 2 connects to pin 2, pin 3 connects to pin 3 and pin 5
connects to pin 5.
The projectors can be daisy-chained using RS232. Please, refer to Appendix C for de-
tailed information about RS232 daisy-chaining.
4 SETTING UP RS232 COMMUNICATION
Baud rate is configurable from the projector’s menu system. Default baud rate is 19200.
This section applies to single projector control with no address information. Please, refer
to Appendix B for detailed information about RS232 daisy-chaining.
5.1 About the protocol
The RS232 protocol is a binary protocol where each command is a series of 32 bytes in
one packet. See Appendix A for command structure. The tables in appendix B have one
row for each command.
The packet consists of a header with 7 bytes, and the packet payload, 11 bytes (see ap-
pendix A). It is important to complete the packet with an additional 14 bytes of padding,
so that the total packet size reaches 32 bytes.
The bytes are numbered 1 through 32. Byte 1 is sent first, byte 32 last. Some columns in
Appendix B show the value to be sent for several consecutive bytes. These are typically
indicated by a range, ie. 14 - 16. This means that bytes 14-16 all have the same value.
The protocol allows for both SET and GET operations. To utilize GET operations the host
needs a routine for receiving and interpreting incoming packets.
5.2 SET_operations
SET_operations are used to force the projector into different modes, like setting bright-
ness and contrast setting, switching between sources, etc.
As seen in Appendix B, each packet is a series of 32 bytes. To control the projector,
simply send the desired packet to the serial port. (An example of how to do this from a
DOS-window is provided in chapter 5.7)
After receiving a packet and executing the operation, the projector will immediately send
a packet in return. The returned packet will contain a PAK (0x1E) (PAK = Packet Acknowl-
edge), followed by the initial SET_operation sent from the host. Total packet size is 33
bytes.
5.3 GET_operations
GET_operations are used to acquire data or status from the projector, such as lamp us-
age hours, total on time, etc.
A response to a successful GET_operation consists of a PAK (0x1E) followed by the initial
GET_operation sent from the host. The requested value resides as a WORD in byte 17
(low byte) and byte 18 (high byte). Total packet size is 33 bytes.

5.6 DESCRIPTOR_operations
To aquire the valid range of an operation, set byte 8 (operation type) to 7 (DESCRIPTOR)
fill in the operation number and send the packet. A successful response will consist of
PAK (0x1E), followed by the standard 32 bytes.
5.7 Example of setting protocol parameters and
sending a command in CMD window
Setting up the COM port, and sending a “poweron” command, where “poweron” is sim-
ply a binary-file with the appropriate packet for turning the projector on:
This returns, when successful, an acknowledgement as described in chapter 5.2 ,
and turns the projector on.
5.8 OSD feedback
RS232 control commands will not produce any OSD feedback. Only keypad and IR
remote control will produce OSD feedback.
5.4 INCREMENT_ and DECREMENT_operations
These operations are used when you want to increment or decrement the excisting value.
The response consists of a PAK (0x1E) followed by the initial operation sent, except for
byte 11, which carries an operation validation code, 0x01. Total packet size is 33 bytes.
5.5 EXECUTE_operations
An EXECUTE_operation triggers a pre-programmed algorithm in the firmware to execute
a certain chain of events. The EXECUTE_operation does not contain any parameters to
indicate a desired value, but simply executes the algorithm assigned to it.
The response is equal to that of the INCREMENT/DECREMENT_operations (see 5.4).
