Appendix A. CRBasic Programming Instructions SDMCD16AC Controls an SDM‐CD16AC, SDM‐CD16, or SDM‐CD16D control device. Syntax SDMCD16AC(Source, Reps, SDMAddress) SDMCD16Mask Controls an SDM‐CD16AC, SDM‐CD16, or SDM‐CD16D control device. Unlike the SDMCD16AC, it allows the CR3000 to select the ports to activate via a mask. Commonly used with TimedControl(). Syntax SDMCD16Mask(Source, Mask, SDMAddress) SDMCVO4 Control the SDM‐CVO4 four‐channel, current/voltage output device. Syntax SDMCVO4(CVO4Source, CVO4Reps, SDMAddress, CVO4Mode) SDMGeneric Sends commands to an SDM device that is otherwise unsupported in the operating system. Syntax SDMGeneric(Dest, SDMAddress, CmdByte, NumvaluesOut, Source, NumValuesIn, BytesPerValue, BigEndian, DelayByte) SDMINT8 Controls and reads an SDM‐INT8. Syntax SDMINT8(Dest, Address, Config8_5, Config4_1, Funct8_5, Funct4_1, OutputOpt, CaptureTrig, Mult, Offset) SDMIO16 Sets up and measures an SDM‐IO16 control‐port expansion device. Syntax SDMIO16(Dest, Status, Address, Command, Mode Ports 16-13, Mode Ports 12-9, Mode Ports 8-5, Mode Ports 4-1, Mult, Offset) SDMSIO4 Controls and transmits / receives data from an SDM‐SIO4 Interface. Syntax SDMSIO4(Dest, Reps, SDMAddress, Mode, Command, Param1, Param2, ValuesPerRep, Multiplier, Offset) SDMSpeed Changes the rate the CR3000 uses to clock SDM data. Syntax SDMSpeed(BitPeriod) SDMSW8A Controls and reads an SDM‐SW8A. Syntax SDMSW8A(Dest, Reps, SDMAddress, FunctOp, SW8AStartChan, Mult, Offset) 494
