Rich brought a couple of hand-outs. The write up, 'Good Screen Design' by Rothrock and Martz illustrates the bases of good screen design. Rich had gone through each items in his list, 'iFIX Picture Guidelines'. His major point is that pictures should be similar to each other to reduce confusions. The 'iFIX Picture Guidelines' is attatched below.
The picture of the cooling system of the first floor has incorrect map and we need to correct it.
We agreed that all the pictures should have either a close button or an obvious way to make it disappear.
Someone suggested that all the general items like help, close and other buttons should be in a horizontal bar at the top of the picture.
When a picture which was generated with different screen resolution than viewing screen it could mess up the picture. Someone suggested that we can use the 'FitToWindow' function to solve this problem.
New type of power supplies arrived. Because Mike Kirk is not avaiable we need someone to install them into iFIX.
Andy said Eva will join the iFIX effort for SVX.
Mark has been working on network hub for iFIX pc's. All iFIX pc's will be hooked up to B0 online network. He also mentioned that Server 3 (iFIX) is not on the UPS system, which supplies power until the generator kicks in when there is power outage. The Servers 1 and 2 (Utilities) are already hooked up to the the UPS system. We think Sever 3 also need to be hooked up to UPS system.
Jonathan reviewed trigger inhibits schemes. His transparancies are attached below. He said subsystem experts may follow Simone's example for trigger inhibit signal.
