On site: Golubieski, Semmer, Militzer, Maclean.
Reinstalled TRH transducers in ventilation units at all levels.
Untaped pressure inlet (13:33 MST)
Started installing Licor 7500's:
43 meters, S/N 1167, port ttyS17. Prior to installing this unit the
total power load of the adam was 13.0 V, 1.4 A.
After installing: 12.6 V, 3.0 A, which gradually reduced
to 12.8 V, 2.3 A. Load of this unit only was
12.4 V, .87 A, as measured with the serial/power box at the adam.
Tried to prepare units 813 and 1163 for installation at 30 meters,
but could not get them to boot and run. Red LED at circuit board
would stay on, or blink on and off. It is supposed to go off once
the unit is running. Measured 8 V at the end of 30 meter cable
with unit attached. Need to reduce this loss
Installed S/N 1163 at 30 meters, but it is not cabled.
Installed S/N 1164 at 15 meters, but it is not cabled.
DC power supply in power enclosure is rated at 3 A, which will not
be large enough to drive system with 5 Licor 7500s.
Installed CRN1. Data is being received. Distance from top of CRN1 boom
to top of tower base plate is 22.38 meters. Chris said that per the
bubble level indicator the unit is quite level.
Distance from top of CRN1 boom to top of 16 meter sonic is 6.31 meters.
So 15 meter sonic is at 22.38-6.31 = 16.03 meters.
Moved network switch from adam to power enclosure. Dave Gochis will
probably use one of the ethernet ports for his Tsoil CR1000.
After this switch, the fiber/copper media converter would not
connect - even after several power cycles of converter and switch.
Had to power cycle the media converter in the seatainer. This
may mean that the fiber network will not always come up after
a power outage.
Installed anti-climb cage on tower.
