of unstable measurement data!
When installing the probe of the capacitive sensor, consider the safe distance from the moving
contact surface to prevent damage to the probe due to too close distance!
When applying the board module, the working power supply should be powered by a linear power
supply or a switching power supply with extremely low ripple noise!
Do not drag SGS (resistance strain gauge), LVDT (inductive), CAP (capacitive) sensor cables!
Please strictly abide by the signal definition of each sensor, do not arbitrarily change the pin line
sequence and cause serious consequences!
4.9 E17/E18 Display and Interface Module
The main control module has one-channel and three-channel versions, with CPU controlling the
24-bit/16-bit DA converter, outputs the analog signal to the power driver module, and measures
the output Signal (micro-displacement, measuring the actual variation of nano-positioning
mechanisms such as various types of PZT or micro-motion stage) of the position sensing module
through the CPU and 16-bit AD converter, display and computer communication.
The LCD display window is a blue screen white character LCD Chinese character display. You
can observe the window to understand the working status of the display and interface (serial port,
USB) module, and provide a good man-machine interface, which makes the operation easier.
The computer interface includes serial port RS-232 and USB. The serial port baud rate is 9600.
The USB interface is a standard 2.0 interface and is compatible with USB1.1. It provides users
with standard comment codes and communication protocols for secondary development.
The digital I/O interface can be set to input or output mode, the input mode can control the output
and stop of the waveform, and the output mode can track the changes of the controller.
The computer can be connected to the controller module through the corresponding interface and
cable. The computer software is powerful and has common waveform output functions such as
sine wave, triangle wave, square wave and sawtooth wave.
The 15-bit membrane button input controls the controller's operating mode and operates the
controller accordingly.
