    3 Read Mode 3.1 Continuous Mode On this mode, reading module read code continuous and automatic. Break after reading one code, break time is changeable. Click the toggle key to pause. Then click to continuous cyclic read code. Default Continuous Mode Time settlement for single read The longest time before first successful reading.

  • Page 12: Induction Mode

    1500ms 2000ms 3.2 Induction Mode After setting, module begins to monitor brightness immediately. When scene changed, module will begin to read until time of image stabilization over. After first successful reading or single reading time out, module will monitor brightness again after some time (changeable) Module will cycle working as above when follow happen: module can’t find code between single read time, then it will stop reading and jump to monitor brightness.
