h1. Minutes:
* Toroid Manufacture Status
** Tim says ceramic, brazed toroids should be here next week for testing
** Toroid coil polarity not resolved yet, will pursue with ISA, with Steve's help
* Will our system be fast enough for IM01, 120Hz Laser Feedback?
** won't be implemented for a while, first operation at 1 - 30 Hz
* Since using only 4 channels of each 16 channel IP330, may as well drive more signals
** i.e. PS status (so IOC knows the toroid box is still alive)
** add another DAC/buffers
* Signal IOC when all 4 channels are ready for IOC ADC to convert
** this should optimize time performance of system
** should be trigger line on cable to IP330.
** drive directly from PIC (with buffer? or just use DAC channel since already buffered)
** Change IOC connector to SCSI to match other end. (straight-through, John?)
* Analog Circuit Design
** Bring Signal Straight to Integrating Op-Amp, no buffer
** Put +/-1 stage immediately after int. op-amp (introduces off-set error, estimate this)
** add buffer circuitry to schematics
* Calibration Circuit Design seems OK
* Use Vern Smith for intra-rack cabling?
* Will Chuck Yee be able to do this job timely? seek other help?
