Local Area Network (LAN) Control (DLA-X7, DLA-X9, DLA-RS50 and DLA-RS60)

In addition to RS-232C and Infrared Remote Control, the DLA-X7, DLA-X9, DLA-RS50 and DLA-RS60 also support Local Area Network (LAN) Control. Full instructions on how to use this are below. These instructions assume a basic knowledge of TCP/IP networking.

Hardware

The LAN control enabled projectors are equipped with a standard RJ45 connection. They can be connected to a LAN, a PC or a controller either directly or via a router, hub or switch using a standard patch cable in the same way as any other network device.

Projector Setup

In order to use LAN Control, the projector must be switched from RS-232C to LAN Control mode. Depending on the particular network configuration, some basic network settings may have to be changed in the projector’s network menu, though this is unlikely.

To set the projector to LAN Control Mode, go to the “Function” menu on the projector, then scroll down to “Communication Terminal” and change this from “RS-232C” (the default) to “LAN”. This will set the projector to LAN Control Mode. It will also enable the “Network” option further down in the same menu. Scroll down to the “Network” option and press “OK”. This will show the projector’s network settings. These should be familiar to anyone with knowledge of TCP/IP networks, but a basic explanation of them is as follows:

DHCP Client – (Available Options Off/On). When set to “Off”, the projector’s IP Address, Subnet Mask and Default Gateway values must be set manually, however the default values will be suitable for most installations. When set to “On”, these values will be obtained automatically from a Dynamic Host Configuration Protocol (DHCP) server on the LAN. Please note that if DHCP is set to “On”, there must be a DHCP server running and reachable on the LAN, otherwise network communication will not work. The default setting is “Off”

IP Address – Sets the IP (Internet Protocol) address of the projector. As with all IP networks, each device on the LAN must have a unique IP address. Duplicate IP addresses on a LAN will cause unpredictable results. The default value is 192.168.0.2.

Subnet Mask – Sets the Subnet Mask of the projector. In most cases the default value will be suitable. The default value is 255.255.255.0.

Default Gateway – Sets the Default IP Gateway of the projector. This is usually used only on larger LANs with multiple sites. In virtually all installations, the default value will be suitable. The default value is 192.168.0.254.

MAC Address – A 6 byte hex number that uniquely identifies the projector on the LAN. The value is unique to each individual projector.

A detailed explanation of the above settings and general LAN setup is beyond the scope of this guide, but the following Wikipedia links may be useful if further information is required:
