Acquire/Send DDC Info
DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up, information from the monitor concerning its resolution specifications.
The DDC information is acquired from the monitor by the PRIMUX. A monitor with DDC support must be connected to the connector "MONITOR" on the User Station and be powered ON for this to occur. The DDC information will be sent to every powered Host Adapter to be retrieved by their connected CPU.
Note: The CPU connected to the Host Adapter must be powered up to receive the DDC information.
To acquire DDC information from the monitor and send DDC information to all powered Host Adapters, press <D> from the Administration Menu. (From Command Mode type
