DIFFERENTIAL SENSOR ADAPTER
The differential sensor adapter is made for use in combination with VISPIRON ROTEC made magnetoresistive speed sensors. This electronic unit transforms the sensor’s analogue signal into a TTL pulse train as an input into the ROTEC speed board.

ROTARY ENCODER ADAPTER

ROTARY ENCODER ADAPTER
Incremental rotary encoders provide information on the angular position of rotating shafts. The encoders generate two incremental signals, phase shifted to each other by 90° el., and a reference mark signal (once per revolution). These signals, having to be square wave TTL level for the measurement equipment, provide information which can be used in the determination of both the shaft‘s rotational speed and its direction of rotation.

ROTEC PHASE SHIFTER
Apart from providing various sensors, VISPIRON does also offer several electronic units for signal processing and adaption of sensor signals. Examples are the rotary encoder adapter (DGADP) or the electronic adaption unit for ROTEC laser sensors.
This group is now enhanced by the phase shifter. Users are offered the possibility to retard an encoder‘s reference pulse by an adjustable number of pulses within one revolution.

This group is now enhanced by the phase shifter. Users are offered the possibility to retard an encoder‘s reference pulse by an adjustable number of pulses within one revolution. The position of the absolute angle can thus be set. The phase shifter can for example be used to align the reference angle for a valvetrain analysis without the user being forced to de- and reconnect the encoder for turning it. Depending on which valve there is to be measured, the number of retarding pulses is simply set on the phase shifter.

TECHNICAL SPECIFICATIONS
• input signal: square level TTL
• power supply: +9 V to +18 V (nominal: +12 V)
• output signal: square level TTL, min. 100 ns pulse width

3-BUTTON OPERATION UNIT

3-BUTTON OPERATION UNIT
The 3-button unit may be connected with a cable to an IEEE-1394 (‚Firewire‘) ROTEC system. The ROTEC system may then, for example, be installed in the boot of the car undergoing test and the 3-button unit allows the driver to run the tests remotely. This applies only to the actual starting and stopping of measurements.

The ROTEC system may then, for example, be installed in the boot of the car undergoing test and the 3-button unit allows the driver to run the tests remotely. This applies only to the actual starting and stopping of measurements.
All ROTEC software setups must be made beforehand via keyboard. The small 3-button unit is connected by an integrated cable to a USB port of the ROTEC system, the ROTECnbk or the ROTECdl datalogger. The computer is configured so that login automatically follows system operating voltage switch-on. The ROTEC software then starts and the appropriate measurement setup is activated. Automatic saving of the measurement data is also provided for.

Buttons:
Green Start - start the measurement
Orange Stop - stop the measurement
Rot Shutdown - close the program and shutdown the operating system.
A double-click of the button within two seconds is required to protect against incorrect operation.

LEDs:
Orange Waiting – awaiting trigger condition
Green Measuring – measurement running
Orange Saving – data are being saved Red Error
