Safety Precautions 1, The ST8 allows input voltage of 7-28V. To ensure that the power supply voltage is consistent, pay attention to the positive and negative polarity of the power supply when connecting. 2, The S1-S4,S4 Ext. signal ports only support a maximum of 2A current. For a larger current servo, connect the output main port to prevent the internal circuit from being burned out. 3, The S1-S4 signal port can only output up to 8.4V, for higher voltage uses the main port.

Product overview The ST8 is a product for testing servos, with up to 28V voltage output, 8-channel signal output, current measurement, curve display and other functions. 4 channels of programmable independent signal, 8 channels of signal output, accuracy of 1 ms. 4 independent current acquisition, respectively, curve display. Multiple measurement modes (speed, count, step, linear). output PWM signals with a period of 33 to 1000 Hz.
ST8 Layout Display Exit S5 port USB port Knob(OK) P1 knob （press，lock) Front S4 Ext.
First start 1, the 7-28V power supply is connected to the input port on the back of the ST8 2, the display shows the boot logo and stays for 2 seconds 3, accompanied by do-re-mi boot sound 4, the boot is completed, the display enters the main interface as shown below: 5, Press [Exit] to start the PWM signal output and test.
================================= 1, Short press 1 [Knob], to determine the key function. 2, Press and hold [Knob] for 2 seconds to set the function for entering the system. 3, Short press 1 [Exit], pause, start, exit function. 4, Successfully operate any key, have didi prompt tone. =================================== Main interface After pressing the [Exit] button after powering on, the system shows the main interface, as shown below: The top 5.
red. 41 ° C is the motherboard temperature, higher than the safe temperature set by the system will alarm and flash red. The right side S1, S2, S3, and S4 are independent 4-channel PWM signals, which are distinguished by different colors and graphically display the pulse width value. The middle grid is a curve display of 4 PWM output current, which is easily distinguished by the corresponding color display on the right side.
Pause interface After booting up or pressing [Exit] on the main interface, you can enter the pause interface, as shown below: When paused, the current curve is paused and the PWM signal is maintained at a fixed value. Rotate [Knob] to adjust the timeline to view the saved current curve. Press [Exit] to exit the pause interface.
Channel setting After selecting a channel in the main interface, press [OK] to pop up the setting options of the selected channel, and the following interface is displayed. 1，Signal source setting Rotate the [Knob], move the cursor to the [Input] [P1] position, press [OK] to modify the source setting. Channel 1 can be set to P1, S5, internal signal, button, and 4 sources. Channels 2-4 can be set to P1, S5, internal signals, buttons, channels 1, and 5 sources. After selecting the appropriate source.
When the P1 source is selected, the PWM output can be controlled by the P1 knob and the position of the knob can be displayed. As shown below: 3，S5 source setting When S5 is selected as the signal source, PWM, PPM, and SBUS signals can be selected. By inputting the corresponding signal on the S5 interface, the received signal value can be displayed and the PWM output can be controlled.
When the PPM signal is selected, the channel can be set from CH0 to CH7, as shown below: When the SBUS signal is selected, the channel can be set from CH0 to CH15.
4，Internal source setting When the signal source selects the internal signal, it can be set to linear and phase modes. These two modes are mainly used for the aging servo test, which will generate a count and will stop working when the set value is reached. It can be turned off in the system settings. When the linear mode is selected, you need to set the step value and speed value. The step value ranges from 1 microsecond to 10 microseconds, and the speed value ranges from 1 millisecond to 10 milliseconds.
When the phase mode is selected, if the PC point is not enabled, it is the second-order mode, which jumps between the two values of PS and PE at 1 second. If the PC point is enabled, it is the third-order mode, which jumps between the three values of PS, PC and PE at 1 second. This mode allows you to measure the response speed of the steering gear.
5，Key setting When the signal source selects the button, the main interface will display PS, PC, PE buttons, you can move the cursor to the buttons on the main interface and short press [OK] to output the corresponding PWM value. The time to turn the angle can be measured and displayed. As shown below: 6，S1 source setting When S2, S3, S4 signal source selects S1, it will follow the S1 setting and output S1 with the same PWM value.
7，Output source setting Move the cursor to the [Output] position to set the range of the PWM output signal with an accuracy of 1 microsecond. If you are in the button source and internal source stage modes, you need to set the PC value.
enter the system setting interface, and rotate [Knob] to switch the corresponding settings, as shown below: Cycle: Output the period of the PWM signal, ranging from 1 millisecond to 30 milliseconds. VoltageOutput : The output voltage of the main port has 11 gears, including turnoff, 5V, 6V, 7.4V, 8.4V, 12V, 14V, 15V, 16V, 18V, 24V, 28V. When it is turnoff, the main port does not output voltage, the PWM output port voltage is 5V, and the load power is 15W.
main port output. SafeTemperature: Above this temperature, the device will stop the main port output. Backlight: The backlight brightness level of the display can be set to 1-10. Buzzer: The tone of the buzzer can be set to off. Language: The system displays the language. English and Chinese can be selected. ThemeStyle: The color style displayed by the system interface. It is divided into bright and dark colors.
After connecting the ST8 to the computer via the USB cable in the box. the computer will recognize the USB flash drive named Toolkit. Download the upgrade file app.upg on the official website to overwrite the files in the USB flash drive to upgrade the firmware.
