Product Description
1. Background Description
This offline marking control board is completely out of the control of the computer, and only needs to store the generated data in advance into the control board or communicate with the outside through the protocol. It is then marking by an external trigger (button), serial port or network communication.
2. System External Interfaces
1 TTL232 interface, 1 input IO, 1 output IO, 1 USB interface, 7GB storage space.
At the same time, the system can be externally connected to usb hub for interface extension (such as: usb to ttl232, usb to network port, etc.), and the specific functions can be extended through later software upgrade.
