The CED 4003 is a simple linear 10k potentiometer, intended to provide manually adjustable signal division. It is cased and has BNC leads that allow input connection from a voltage source such as a 1401 DAC waveform output, with an output connection suitable for an ADC waveform input.
The potentiometer output is controlled by a slider, with markings and writeable labels.
Case size: 166mm x 70mm x 28mm, lead length 2 metres.
The input voltage should not exceed 30V.
The CED 4704 V2 is a linear potentiometer with a USB interface. The linear position of the potentiometer can be streamed back as a percentage of full scale to the USB host to a resolution of 0.1%. The interface is a Virtual Serial Port, through which simple commands are sent to the device and responses returned as text strings.
The potentiometer is powered from the USB port and draws 50mA.
|SL or ?SL return the position of the slider as a percentage of full scale xxx.x or xxx
|start a stream of slider percentage returns at the current rate until SS received
|stop the sending of slider percentages
|set the time interval of percentage value sending in milliseconds (n = 10 to 32767, default 100)
|give a 200ms flash of the green LED on the slider box
|set printing values right-justified (RJ) in n columns, n = 1 to 10; enable using OP11
|OPnv / ?OPn set / interrogate options stored in internal EPROM:
|OP00 / OP01 do not / do add LF after CR in returned values
|OP10 / OP11 print single column LJ / print in n columns RJ (n set by VCn)
|OP20 / OP21 print decimal tenths / print integer values only
|OP30 / OP31 print slider range as 0.0 to 100.0 / print as ±50.0 with centre zero
|cancel a red LED and return the last error code; returns "000" if none
|return "CED slider pot xx" where xx is the last two digits of the serial number
|return the firmware revision
|return the full serial number (SLxxxx)
|return the travel offset that is subtracted before reporting each slider position value
