Status
Designed parallel port I2C interface for communcating with sensor
network 1/3/2004.
Motherboard tested good 1/19/98
Hard drives tested good 1/20/98
WinSound card apparently incompatable with Linux 2.30 kernel, as no
exisiting
driver can locate the card. 1/28/98
Installation of SBPro2 successful 1/29/98
Motherboard/HD power consumption measured: +12V@1.2A, +5V@5.6A
+5V(HD)@440mA(spec),
+5V(7100 card)@325mA(spec) 2/21/98

Loaded DC-DC system test high-current +5 supply ok, multi-voltage
supply failed
6/16/99. Multi-voltage supply to be replaced with Tri-M HE104.
Replacement Multi-voltage supply test successful!!! 7/23/99
Locomotion system test successful!!! 7/23/99
STH-V2 test on 12/15/1999 yeilded defective right CMOS camera. Sent
back
to Videre for repair. 12/23/1999
STH-V2 returned from repair on 2/2000 after much back-and-forth with
Videre.
With the current framegrabber driver using SVM for a short period of
time
causes teh CPU to lock-up. My current theory is that one of the
framegrabber
cards is overlapping some of the video memory with the other capture
card,
or the VGA adaptor in an inappropriate way.
I am designing a modular BS2-based sensor array to offload the work of
aquiring sensor data from the main CPU. A test circuit has been built,
and tested 4/22/2000. All of the boards will be daisy-chained with
RS-485,
or I2C (ala RWI). The main CPU will either have a background sensor
aqusisition
daemon to capture the continuous sensor datastream, or use the 'shared
memory" approach to aquire sensor data ony when the host CPU needs it.
