ES PROPERTY
Property ID: 22 (0x16)
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0x3F ‘?’
Description: This character is sent as the end sentinel for all tracks with any format. If the
value is 0 no character is sent. If the value is in the range 1 – 127 then the
equivalent ASCII character will be sent.
This property is stored in non-volatile memory, so it will persist when the unit
is power cycled. When this property is changed, the unit must be reset (see
Command Number 2) or power cycled to have these changes take effect.
MSR DIRECTION PROPERTY
Property ID: 3 (0x03)
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 2 (Withdrawal)
Description: This value is a byte that represents the devices magnetic stripe read direction.
The device will output card data when a card is swiped in the direction
indicated by this property. The value can be set to 1 for insert, 2 for
withdrawal or 3 for both directions. This property is stored in non-volatile
EEPROM memory so it will not change when the unit is power cycled. When
this property is changed, the unit must be power cycled to have these changes
take effect. If a value other than the default value is desired, it can be set by
the factory upon request.
Note that this reader reads better when a card is removed from it than when a
card is inserted into it.
