Interface type property – MagTek USB KB SURESWIPE & USB KB SWIPE READER User Manual

Page 37

Section 4. USB Communications

If this device needs to be able to emulate all country’s keyboards then this
property should be set to 1 (ALT ASCII code). The tradeoff is that the ALT
ASCII code mode is slightly slower than keymap mode because more key
presses need to be transmitted. Some applications are not compatible with
ALT ASCII code mode.

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.

Default Value:

1 (keyboard emulation)

Description:

The value is a byte that represents the devices interface type. The value can
be set to 0 for the HID interface or to 1 for the keyboard emulation interface.
When the value is set to 0 (HID) the device will behave as described in the
HID manual. When the value is set to 1 (keyboard emulation) the device will
behave as described in the keyboard emulation manual. This property should
be the first property changed because it affects which other properties are
available. After this property is changed, the device should be power cycled
before changing any other properties.
