SAB-Q2 Quick Start
This document aims to provide a systematic setup procedure to enable you to setup and use your SAB-Q2
as easily as possible. This guide will concentrate on connections and basic setup. More information is
available for advanced setup, refer to the SAB-Q2 manual. If you do not have a SAB-Q2 manual, call
Rapid Controls or visit the Rapid Controls website, www.rapidcontrols.com.

1. Power Connection (Connector J4)

Power input to J4 provides power to the board and the sensors. Refer to the sensor requirements before
choosing a power source for the SAB-Q2. The following pins must be connected:
Pin 1 is connected to either +24VDC or +15VDC depending on the requirements of the sensor.
Pin 2 is connected to ground.
Pin 3 is connected to –15VDC if required by the sensor. Otherwise, no connection is made.

  • Page 2 Pin 14 is connected to the sensor –power wire (MTS: blue) if needed. 3. Quadrature Connections (Connector J2) The quadrature output from the SAB-Q2 is provided on connector J2. This connector also provides marker outputs (quadrature Z line); see the manual for details. The following connections should be made for operation of quadrature channel 0: Pin 1 is connected to the quadrature line A input of the controller.
  • Page 3 Pin 1 is connected to logic ground on the host computer (pin 5 on a DB-9 connector, pin 7 on a DB-25 connector). Pin 2 is the SAB-Q2’s receive line and is connected to the host computer’s transmit line. (pin 3 on a DB-9 connector, pin 2 on a DB-25 connector) Pin 3 is the SAB-Q2’s transmit line connected to the host computer’s receive line.
  • Page 4 Table 1: Input and Output Configurations The followings pins are used for the send all inputs and sensor status outputs: Pin 6 is the send all input for channel 0. Activating this input will cause the SAB-Q2 to send the absolute position for channel 0.
  • Page 5 7. Sensor Setup A. Transducer Type The SAB-Q2 default setting is RPM. If a SSI or PWM sensor is being used then sensor type must be changed to SSI or PWM in the setup menu. Recommended SSI sensor is 24-bit binary SSI.
