A R C O N

The name is simply a contraction of "ARray CONtroller", the hardware/software system which operates all CCDs at CTIO, the 8K Mosaic on Kitt Peak, and several CCDs on the WIYN telescope.   Each electronics box can  operate a quad readout CCD.  Four are used in the case of the Mosaics.   Twenty were deployed in all.  Some systems at CTIO are still being upgraded to the latest version of the ADC. VIdeo and "Voltage/Temperature/Telemetry" cards, but no new systems are being built since the embedded microprocessors have become obsolete.
These pages are being drastically revised.

SUN Daemons

A optical fiber connects the Nexus node to a Transtech S4 Sbus interface board, which in turn is driven and controlled by a UNIX daemon called muxnex which routes information between TRAMS, the user, and other devices such as Telescope Control computers, motor controllers, LSI-11 computers controlling RC spectrograph,

User/IRAF Interfaces

muxnex also exchanges commands and information with end user command line interface programs arsh and clarsh.
