Notes for access operations:
◆Access operations only for the selected tag.
◆It can read multi-byte data of tag at the same time, length of the data is not limited.
◆Multi-byte data could be written. If error occurs, the reader will stop writing, but data which has been
written will not change, thus reader will return the number of bytes which have been written successfully.
◆Only one-byte data of tag can be locked each time.
◆Only one-byte data state of tag is queriable each time.
◆Operation to lock tag is permanent and irreversible.
2.6 Other Settings
2.6.1 Operating Temperature Monitoring
Reader will generate heat under intensive work. Users can monitor the internal temperature via built-in
temperature sensor to avoid reader overheating (Operating temperature over 65℃). Temperature
Monitor illustrated as below:
2.6.2 Set GPIO Level
General-purpose input/output (GPIO) is a generic pin on an integrated circuit whose functions (including
whether it is an input or output pin) can be controlled (programmed) by users. This reader provides two
inputs (GPIO1 and GPIO2) and two outputs (GPIO3 and GPIO4).
