WP11462 Run latest Picket Fence code on nuc5

Edgard, Erik, Dave:

Erik upgraded the userapps git checkout of the picket fence code last Friday, I restarted the code on nuc5 this morning. The only change I made was to add the display of the state borders to the map.

WP11469 Testpoint Stress Test h1pemcs

EJ, Joe, Dave:

With the static DAQ DQ list unchanged, I tested how many testpoints could be opened on h1pemcs.

Result: 62 TPs can be opened (get low level DAQ error if 63 are attempted). PEM measurements require 43 accelerometer TPs, which leaves 19 additional TPs which can be used for PEM injection measurements.

Test code is h1pemcs_testpoint_test.py (web_svn) more details of the test can be found in the comment header block.

WP11468, WP11473 Reconfigure h1didivideo[0,1,2] network ports and reboot

Jonathan, Patrick:

The h1digivideo[0-2] machines were made to be dual-homed, giving the camera LAN a separate ethernet connection. As part of this upgrade, the machines were rebooted which cleared the almost full memory.

WP11477 h1susey BIO readback error

Fil, Rahul, Dave:

Fil and Rahul investigated the ETMY reactionary chain BIO readback, showing F1 DAC drive was in test mode. During the investigation the h1susey front end was fenced from Dolphin and power cycled.

The Contec6464 card for the R0 signals was swapped with a spare:

Removed Card GCRBS96004326
Installed Card ADRBS96001388

The problem was found to be in the cable connecting the Contec6464 card to its BIO Chassis. This means that the removed card is most probably a good card.
