6.3.3.6:
READER_LED_CONTROL_BY_FW
This Escape command is used to enable/disable LED control by firmware.
Input:
The first byte of the input buffer contains the escape code. The second byte specifies whether LED
control by firmware should be disabled or enabled. The output buffer is NULL.
Output:
No response is returned for Set State. For Get State, a 1-byte response is received.
Output buffer
NULL, or current state
6.3.3.7:
READER_RD_WR_USER_AREA
This Escape command is used to access the user data area in the reader. The user area is located in the
non-volatile memory of the reader, so data will be retained even after a power cycle.
NOTES:
•
Frequent writes should be avoided, because the non-volatile memory supports only 100K writing
cycles.
•
A maximum of 249 bytes can be read and written. The sector can be read and written only as a
whole.
•
If complete data (249 bytes) is not given during a write operation, then random data will be padded
to the given data and then written. If you want to modify only part of the data, read the entire 249
bytes, modify the data you want to change, and then write it back to the reader.
Input:
The first byte of the input buffer contains the escape code. The second byte specifies whether the user
area is to be read or written.
