As shown in the concept drawing, once you do EDID configuration, then each EDID is stored in
EEPROM at the front of DVI input and the video sources could read out each EDID in the EEPROM.
The beauty of working is that the video sources enable to start reading EDID in boot-up even though
the ODM1818 and connected displays are not powered on yet.
Connection of Optical DVI cables and modules for long distance extension
The ODM1818 supports connection of Optical DVI cables or modules to the inputs and outputs.
We strongly recommend not using copper DVI cables over 3 m (10ft) extension, but using fiber-optic
DVI products.
Initializing ODM1818 and Installation Guide
INITIALIZATION
Plug a adequate AC power cord in the shipping group to the AC/DC power adaptor and plug the DC
cord to the +12VDC connector on the rear panel while caring the arrow mark on the connector of the
DC cord. Push POWER button on the front panel then you could see;
Red LED lit on the button and Initializing … 18X18 DVI Matrix on the display window and
sweeping Green and Red lights on the Input and Output buttons respectively. Finally shows
USER MODE on the display window, which means being ready to accept commands.
RACK MOUNTING
Before installing cables, the ODM1818 has to be mounted on the rack. On both front faces of the
side chassis are two holes tapped to screw L-shape plates to the rack.
CONTROL CONNECTIONS
Commands and functions of the ODM1818 are accomplished through the RS-232C and Ethernet
connection. USB interconnection is valid only with Proprietary Windows PC software on CD in the
shipping group.
RS-232C Control
Connect the ODM1818 to a video controller or PC with a RS-232C cable having D-sub 9 pin males’
connectors.
Ethernet Control
Connect the ODM1818 to a video controller or PC with a cable having RJ 45 connectors.
Direct connection of PC or video controller to the ODM1818: Use an Ethernet cros-
sover cable.
The PC which is connected to the network is typically configured to have a
dynamic IP address by a network DHCP server. If the PC connects directly to
the ODM1818, the server in your network is not available for making ad-
dressing the PC.
The PC should be manually set in a static IP address. Refer to the Setting the
PC IP address on page 14.
LAN connection of the ODM1818: Use a straight Ethernet cable.
The ODM1818 is configured at the factory with the default IP address,
192.168.0.88. Before connecting to your network, verify if it is valid on the
network.
The IP address can be reconfigured by front key buttons or command lines
over RS 232, Ethernet and USB.
