Digital Sensor Card USB – Potentiometer Input (DSCUSB-PT)
The DSCUSB-PT is a compact, high-precision potentiometer input module; converting a resistance based input (potentiometer) to a digital output. Can be used with resistance based sensors to indicate position, rotation and angle. Aimed at applications which require high accuracy.
Simply by plugging the device into a PC, data can be extracted from the potentiometer input to the DSCUSB-PT for a wide range of applications. This is achieved using the DSCUSB Toolkit software which is a simple configuration tool designed specifically for configuring DSCUSB modules. It allows configuration, calibration, logging and parameter management of the modules.
The output is factory calibrated to give an output from between 0% and 100% but this can be scaled by the system integrator or the user to give engineering units instead.
This free-standing module is fitted with 9-way ‘D’ type socket for potentiometer and optional temperature sensor connections. A micro USB socket accepts a USB lead with type ’A’ connector at the PC end.

Q: How do I communicate with the USB device?
A: Using a simple ‘Virtual Com Port’, the DSCUSB-PT communicates as if the device is connected to a serial port. The device addressing allows up to multiple devices.
Q: Is temperature sensing available on the DSCUSB-PT
A: An optional temperature sensor module (DTEMP) is available which will enable an advanced 5-point temperature-compensation of measurements.
Q: Is there Linearity compensation in the DSCUSB-PT?
A: Advanced 7-point linearity compensation available as standard.
Q: How stable is the DSCUSB-PT device?
A: 10ppm/°C basic accuracy (equates to 16 bit resolution).
Q: Are there self-diagnostics capabilities?
A: Continuous monitoring on the DSCUSB for faults such as over/under-temperature, power failure. All fault warnings are retained on power-fail.
Q: What are the output options of the DSCUSB-PT?
A: We currently only offer the device in ASCII protocol.
Q: Tell me about DSCUSB-PT low current?
A: Functions as a ‘Low Power Device’ i.e. draws less than 100mA (one unit load) when connected to a 500 Ohm load sensor.
Q: Can I use the DSCUSB-PT with my own software?
A: Yes. The DSCUSB-PT appears as a virtual com port. The protocol is ASCII and is described in the advanced manual.
Q: Can I check the input of the DSCUSB-PT is working correctly?
A: Yes. There is a 50% reference output on pin 3 of the D-Type connector. Disconnect the sensor and connect pin 3 to pin 4 of the D-Type connector. This should give a 50% value of ±1%
