Setting up LAN communication

The projector is shipped with a set of default settings, these are as follows:

Description Value

DHCP On

IP address 0.0.0.0

Subnet mask 0.0.0.0

Default gateway 0.0.0.0

TCP/UDP port 1025

Username admin

Password admin

Before you connect the projector to your LAN make sure that the IP settings are set correct according to your LAN conguration.

IP settings can be changed from menu system or from the projector webpage. It can be set automatically by using DHCP (Dynamic

Host Conguration Protocol) or manually by disabling DHCP and set IP address, Subnet mask and Gateway.

Use of DHCP requires a DHCP server in the network.

When enabling DHCP please allow up to a minute for the projector to receive IP settings from the DHCP server. The IP address will be

updated and shown in the menu system.

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)

cable directly from the computer to the projector, or two straight-through TP cables with a HUB or a switch between them.

When the projector is set up with proper IP settings, you should be able to control it.

To verify the communication you can connect to the projector webpage. This is done by starting up an internet browser, like Internet

Explorer, Opera, Firefox or similar. Then type the projectors IP address (found in the projector network menu) in the address bar.

You will then see a login screen, see Figure 1.

Figure 1 : Login

Type in the projectors default login name (admin) and password (admin), both are case sensitive. If both are correct, you will se a

conguration website, see Figure 2.

Figure 2 : Web page

On this page you can setup the projectors IP address, subnet mask, default gateway, projector port (TCP/UDP) and password. This

page also displays the current version of network rmware the projector is running.

Setting up RS232 communication

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.

RS232 Communication parameters

Table 1 shows supported rs232 settings:

Parameter Data

Baud rate 4800, 9600, 19200

Parity N

Databits 8

Stopbits 1

Flowcontrol None

Table 1: RS232 parameters

Baud rate is congurable from the projector’s menu system. Default baud rate is 19200.

Communication Protocol

This section describes how to use the communication protocol to control projectors remotely.

When the projects are connected to either RS232 or LAN you can control the projectors through this ASCII based protocol.

Note: Some commands will generate OSD feedback. This can be turned off from the projector’s menu system or by setting

“OSDC” to value 0 (OSD off) or value 1 (OSD show only warnings).

Overview

The protocol has the following denition:

HEADER SEPARATOR ADDRESS SEPARATOR MESSAGE BODY TERMINATOR

1 byte 1 byte 1 -3 bytes 1 byte N bytes 1 byte

Field Description Comment

Header ASCII character ‘:’ Required

Separator ASCII character ‘space’ Optional

Address 1 – 3 bytes address Optional

Terminator CR carriage return (0x0D) Required

Message body

The message body structure is as follows:

MNEMONIC SEPARATOR] MODIFIER SEPARATOR VALUES

1 byte 1 byte 1 -3 bytes 1 byte N bytes

Field Description Comment

Mnemonic 4 bytes key identier, not case sensitive Required

Modifer Single char symbol Optional

VALUES 1 – 3 bytes address Optional

Separator ASCII character ‘space’ Optional

Mnemonic

The Mnemonic is 4 bytes key identier, know as the ASCII command.

Example: POWR, SABS, IVGA

Modiers

R Relative change. Value given will be reletive to the existing value.

Example: :BRIG R10 will increase brightness with 10 steps

ARequest acknowledges. This modier is the only

used to read back the result of the command.

Default all commands send acknowledges so this will not be

necessary.

?Get current value

?M Get maximum value

?N Get minimum value

?D Get default value

?S Get default step value

Acknowledge/Response

Acknowledge is optional and ON by default. Auto acknowledge can be turned on and off with ECHO commad. It can also be activated

on a per command basis using modier A.

ACK ADDRESS SEP COMMAND SEP VALUE TERM

1 byte 3 bytes 1 byte 4 bytes 1 byte 6 bytes 1 byte

Field Description Comment

ACK ASCII character ‘%’ Always

SEP ASCII space Always

VALUE 6 bytes return value Always

TERM Termination char 0x0D (CR) Always

Most commands value returns the actual value of the requested command. If the requested command is not valid the response may

include an error message.

Code Error message Description

!00001 Access denied Current access level is too low

!00002 Not available Command currently not available.

Ex. contrast is not available when the

projector is searching

!00003 Not implemented Command to implemented

!00004 Value out of range Value out of range

Some commands could return a value that is more than 6 characters, for instance strings.

Code Extended info Description

e00001 Extended info, string A description string follows

Example:

> :seri ?

> %001 SERI e00001 07010001

Examples

The protocol accepts one single SPACE between elds, or no SPACE between elds.

‘CR’ ASCII value carriage return, hex value 0x0D.
