## Table - Property 1.2.7.1.1.2 Device Reset Occurred Notification Acknowledged


Property Description
Property OID	1.2.7.1.1.2 / 0x010207010102
Name	Device Reset Occurred Notification Acknowledged
Description	The host can use this property to acknowledge it has received the Device Reset Occurred notification in Notification 0x1001 - Device Information Update and to request that the device stop sending it. Alternatively, because the device automatically sets the value of this property to 0x00 on boot, the host can use this property to detect power cycles or resets using a polling method. To implement this, the host should read the value on a set schedule (for example, every 2 seconds). If the host finds a value of 0x00, a power cycle or reset has occurred, and the host should set the value back to 0x01. From that point until the next power cycle or reset, the value will remain 0x01. Changes made to this property will not persist after a power cycle or reset. After a power cycle or reset, this property has a value of 0x00 until the host changes it to 0x01.
Securing Key	None
Min. Len (b)	1
Max. Len (b)	1
Data Type	Binary
Valid Values	0x00 = Not acknowledged. Only the device can set to this value. 0x01 = Acknowledged. Do not continue to send the notification.
Default	0x00

## Table - Property 1.2.7.1.1.4 Auto Reset Configuration


Property Description
Property OID	1.2.7.1.1.4 / 0x010207010104
Name	Auto Reset Configuration
Description	This property controls the device’s auto reset feature. The auto reset feature can be configured such that the device automatically resets 23 hours after booting up or at a specific time of day. Or device can be configured to enter a restricted mode after 24 hours without a reset or power down. When device enters restricted mode it will respond to first command received with Response Message - Request Handler: Group 0x02, Subgroup 0x01, Code 0x1D. Device then sends Notification 0x1001 – Device Information Update: Category 0x00, Reason 0x01 - Reset will occur soon. Device will then auto reset. The auto-reset feature cannot be disabled. See 24 Hour Automatic Reset PCI Requirement for more information. Changes to this property do not take effect until the device is power cycled or reset.
Securing Key	None
Min. Len (b)	2
Max. Len (b)	2
Data Type	Binary
Valid Values	First byte 0 - 23 hours and second byte 0 - 59 minutes = Reset at the time of day specified. The time of day specified should be 24-hour Universal Time Coordinated (UTC). For example, values of 0 0 would be 12:00am UTC and values of 23 59 (0x17 0x3B) would be 11:59pm UTC. First byte 0xFF and second byte 0xFF = Auto reset 23 hours after booting up. First byte 0xEE and second byte 0xEE = Device enters Restricted Mode 24 hours after booting up.
Default	0xFF 0xFF

## Table - Property 1.2.7.1.2.1 User Event Notification Controls Enable


Bit Property Description
Property OID	1.2.7.1.2.1 / 0x010207010201
Name	User Event Notifications Enable
Description	The host can use this property to enable notification reasons defined in Notification 0x1001 - Device Information Update in the User Events Category. Each bit enables a specific Reason by setting that bit to 1. Byte 0 is the first byte, bit 0 is the LSB of each byte. The device only detects these user events and sends these notifications when it is idle. While processing a command (not idle), such as when processing a transaction with Command 0x1001 - Start Transaction, the device only sends notifications related to the command it is currently processing. Notification reasons may consume power when idle. For example, enabling Contactless reasons requires the device to continuously consume some radio frequency power to detect the presence of a contactless card when idle. To conserve power, only enable the notification reasons that are required by the solution design, if any. The readers and their associated notifications will be disabled if the battery charge is 5 percent or lower. Changes to this property do not take effect until the device is power cycled or reset.
Securing Key	None
Min. Len (b)	4
Max. Len (b)	4
Data Type	Binary
Valid Values	Byte 0 · bit 0 = Reason: Contactless Card Presented · bit 1 = Reason: Contactless Card Removed · bit 2 = Reason: Card Seated in Slot · bit 3 = Reason: Card Unseated from Slot · bit 4 = Reason: Card Swiped · bit 5 = Reason: Touch Sensor Press Detected · bit 6 = Reason: Touch Sensor Release Detected · bit 7 = Reason: Barcode Read Detected Byte 1 · bit 0 = Reason: Encrypt Barcode Reader Event Data · bit 1 = Reserved (set to 0x00) · etc. Byte 2 · bit 0 = Reserved (set to 0x00) · etc. Byte 3 · bit 0 = Reserved (set to 0x00) · etc. Any byte / bit not listed here is reserved for future use. The host should set those values to 0, so if a future revision of firmware starts using those bits, the related notifications will be disabled and will not affect the existing host software.
Default	0x00, 0x00, 0x00, 0x00 (all User Event notifications disabled)

## Table - Property 1.2.7.1.3.1 Maximum Battery Charge Level (Deprecated)


Property Description
Property OID	1.2.7.1.3.1 / 0x010207010301
Name	Maximum Battery Charge Level
Description	This OID has been deprecated. The OID can be written or read but it will have no effect of the device’s behavior. The host can use this property to control the maximum charge level for the battery. All charge percentages reported or displayed will use this percentage as 100% charged. Setting this value to lower than 0x64 (100%) will increase the life of the battery but reduce the run time when running from the battery. The Maximum Battery Charge Level takes effect immediately after the host changes it.
