SAB-Q2 Quick Start 4 of 5 January 12, 2011
5. Send All nputs and Sensor Status Outputs (Connector J1)
Connector J1 is also used for send all input and sensor status outputs The two send all inputs
command the SAB-Q2 to send the absolute position of the sensor over the quadrature channel The
sensor status outputs show the status of the sensors The output will be active when the sensor is
operating properly The inputs are bi-directional and can source or sink current depending on the
voltage applied to J1-8 If the controller has a sinking output apply + 12 to 24 VDC to J1-8 and allow
the controller to ground the appropriate send all input to cause the send all function If the controller
has a sourcing output apply ground to J1-8 and allow the controller to source +12 to 24V to the
appropriate send all input to cause the send all function The X2 jumper connects the status outputs to
match the choice of common applied to J1-8 If the input common is grounded then the outputs must
be jumpered to be sinking If the input common is connected to +12 to 24V then the outputs must be
jumpered to be sourcing

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
Pin 7 is the send all input for channel 1 Activating this input will cause the SAB-Q2 to send the
absolute position for channel 1
Pin 8 is the I/O common It should be connected as described in Table 1
Pin 9 is the channel 0 sensor status output An active output indicates a good sensor
Pin 10 is the channel 1 sensor status output An active output indicates a good sensor
6. nitial Power Up
After all connections are complete and have been checked for errors, apply power to the SAB-Q2 The
red board status LED should blink A green sensor status LED should light for each connected sensor
with a magnet
If the board status LED does not blink when power is applied, check that your power connections are
correct (see Section 1)
If your sensor is a PWM sensor, you must perform some setup before determining correct sensor
operation Please perform the setup described in sections 7 and 8a before continuing with this section
If the sensor status LED(s) do not light, appear dim or flicker, check that the sensor magnet is installed
as prescribed in your sensor documentation If the LED(s) still do not light, remove power from the
SAB-Q2 and verify all sensor connections
If, after insuring the sensor connections are correct, the SAB-Q2 still does not light the sensor status
LED(s), verify that your SAB-Q2 model is capable of supporting your sensor The SAB-Q2-?-RPM
