3.3 Connections
Connections to the AVU4004A (local) and AVU4001A-RX (remote) modules do not need to follow the precise order given in this
user guide although it is recommended that you do not apply power to the local module until all other connections have been
made.

3.3.1.2 DDC information
DDC information about the video displays is not sent from the receiver modules. Instead, the local module holds a standard set of
DDC details which are suitable for most video displays. If the standard details are not suitable, temporarily connect the local mod-
ule (using the port) directly to the video display that is to be emulated and power on the screen and the local module. In cas-
caded installations, only the initial local module needs to be taken through this procedure.
If the DDC information is different to that already held, the red indicator (adjacent to the LINK4 socket) will flicker rapidly for 2 to
3 seconds while the new information is stored.
If a problem occurs while attempting to harvest DDC information, the red indicator on the local module will show a number of
distinct flashes. Note the number of flashes in case you need to contact technical support, but otherwise retry the procedure.
