A Linux control PC permits remote operation and monitoring of all receiver functions. The same PC-cards which are now being used to provide bias to the SIS junction, magnet, and LNA on the SMTO 230/490 and AST/RO receivers will be used here. A separate computer control card is ``daisy-chained'' with the older cards to allow remote operation. On the control card the manual potentiometer is replaced by a digital potentiometer programmable over a serial line. Serial lines will also be used to monitor SIS, LNA, and magnet bias as well as the temperatures and pressure within the cryostat. Eventually, the mechanical tuning of the LO chain will be controlled over a serial line from the instrument control computer.
