When using the VETAR connected to the HDMI port of the root MACB the settings for all the MACB in the system 0x3.
This setting takes the Clock and Data line from the input HDMI and outputs it via teh HDMI output ports.
When using the Emulator connected via the SMA connectors on the back of the root MACB then the setting for the root MACB |

During the installation of the 4 new HDMI cables for aidas13-16 the HDMI cables between the MACB Root and the MACB leaves were looped through the cable
guide at the top to support them more
This may improve their connection and reduce the chance of WR errors seen in S460/S452

The behaviour of the DSSSD leakage current at low voltages and during biases is unusual and varies depending on how the adapter boards are connected
To summarise the behaviour I have observed

|
LEC fast comparator has been set to 0x2 (200keV) which is *very* low and means the fast comparator will be triggering on noise.
