Setting up LAN communication
The unit is shipped with current default settings:
Description Value
DHCP On
IP address 0.0.0.0
Subnet mask 0.0.0.0
Default gateway 0.0.0.0
TCP port 40400
Before you connect the units to your LAN make sure that the IP settings are set correct according to your LAN configuration.
IP settings can be changed from Control Application. It can be set automatically by using DHCP (Dynamic Host Configuration Protocol)
or manually by disabling DHCP and set IP address, Subnet mask and Gateway.
When enabling DHCP please allow up to a minute for the unit to receive IP settings from the DHCP server.
If there is no DHCP server in the network the unit will be assigned a “zero configuration” address, 169.254.0.0/16.
Reset network settings
Reset the network settings to default by press and hold the front button for 5 seconds.
Communication Protocol
This section describes how to use the communication protocol to control units remotely.
When the units are connected to LAN you can control the projectors through this ASCII based protocol. Commands must be sent
using TCP/IP port 40400.
Timing
General timing constraints:
• Wait 30 seconds after power on before sending next command.
• Wait for response before sending next command.
• Minimum 2 seconds delay before resending if no response received.
• Minimum 500ms delay between commands.
• Minimum 5 seconds delay after sending 20 commands
Overview
The protocol has the following definition:
An ASCII command consists of a semicolon, a four letter command followed by a command parameter. If you input the command
followed by a question mark, the set value will be outputted. If you don’t enter any command parameter, the default value will be set.
Access level
Access level Rank
Development user 5
Manufacturer 4
Service partner 3
Power user 2
End user 1
After setting the access level, all commands with the same or lower rank will be available.
