Length (bytes): 1
Default value is 0x0F (GPIO pins are logic high).
A one in the bit position indicates that the corresponding GPIO pin is logic high.
A zero in the bit position indicates that the corresponding GPIO pin is logic low.
Bits correspond to the pins as follows:
Read/write
Puts the reader into sleep mode.
Parameter address: 0x000C
Length (bytes): 1
Default value is 0x00 (active).
Writing a value 0x01 to this system parameter puts the reader in sleep mode.
Sending a single byte on the interface that put the reader to sleep wakes the reader from sleep
mode.
NOTE: SOFTWARE SLEEP MODE DOES NOT FUNCTION IN USB COMMUNICATIONS.
This is planned for future firmware releases.
Write Only
Sets the number of times a tag command will be retried internally.
Parameter address: 0x0011
Length (bytes): 1
Default value is 0x03
In very time dependent applications, it is recommended to set this parameter to 0 as this
removes much of the variability of response time.
In most situations, a retry number of 3 is sufficient.
Read/write
WARNING: Setting this parameter too high can cause very long response times when there is
no tag or a failing tag in the field.
