OM9100 is completely out of the control of the computer and only needs to be generated in advance. The data is stored on the board or communicated with the outside through the protocol, and then through external contact (key), serial, or network communication to mark it.

1. Abundant peripheral interfaces

With 3 serial ports, 2 USB, 1 100M Ethernet port, and 17 external interrupt GPIO, this offline board has abundant peripheral expansion interfaces, making it highly expandable and easy to communicate with external interfaces.

2. Functions can be realized.

2.1 How to Generate Marking Content

① Save in advance.

Put text, QR code, barcode, serial number, date, bitmap, vector diagram, and other data into the offline board in advance, and then trigger marking.

② Generated by an external protocol

By formulating the protocol, the offline board can receive data through a serial port or network port and then generate marking content (currently under development).

2.2 Trigger Marking

External IO: trigger marking by judging the IO status. Through serial communication, according to the protocol, control marking by receiving serial data.

③ Through network communication, according to the agreement, control marking is achieved by receiving network data.
