USB-303 encoder adapter

product description

USB303 is a scale reading and transmission device based on USB communication. Can be connected to three encoders and a measuring head. When the probe is triggered or the scale RI point is found, the three-axis data at that moment will be locked. When the probe is triggered, it also returns a direction point that indicates the direction of movement of the probe. USB303 is defined as a HID device, which requires no driver and is plug and play. USB303 provides the underlying communication interface of the HID device, RationalUsbHid.dll, to complete device control and data exchange. The functional interface, RationalScale.dll, interacts with the upper-layer program for secondary development.
Features
1 Independent 3-axis 24-bit reversible counter
2 When triggered externally, the three-axis counter is latched at the same time, and the three-axis latch delay is less than 20ns
3 1.0 Hz four-phase input
4 A and B phase signals of each axis support single-ended input or differential input
5 When searching for the RI point of the optical scale, the polarity of the RI signal, A-phase signal, and B-phase signal can be selected
6 The positive and negative of the counting direction can be controlled
7 Digital filtering, can handle abnormal signals
8 One independent external trigger, can latch count value for any axis
9 no less than 30 frames per second
10 The USB303 device is connected to the computer with only one USB cable. The traditional design uses the PCI design, which is inconvenient for installation and maintenance. It is particularly suitable for applications in notebook computers. The use of this scale data transfer box for data transmission installation and maintenance Convenience.
