P1040502-015 05/09/2013

If the key cache is cleared all previously established encryption keys are lost, and it will be

necessary to go through the key exchange protocol the first time each new terminal is paired

with the printer.

Display Flip

It is now possible to invert the orientation of the display (180°) to make it easier to read in

some installations, e.g. when mounted to a wall or a fork lift. It can also be configured to

automatically invert when docked in a cradle. It is necessary to restart the printer after

changing the orientation setting.

Examples showing how to set the display to normal (default), inverted, and automatic mode

are shown below. Remember to send the device.reset command after changing the value. The

final example shows how to read back the current status:

Configuring the 802.11 n Country Code

When configuring the 802.11 n radio it is important to configure the wlan.country_code

parameter in order to define the channels allowed in that country, group of countries, or region.

The list of country options is determined by the wlan.region code parameter, which is set at the

factory based on the Group designator in the printer SKU, as indicated by the “?” as follows:

QNx-xxxx?xxx-xx. The choices are shown in the table below:

! U1 setvar "display.orientation" "normal"

! U1 setvar "display.orientation" "inverted"

! U1 setvar "display.orientation" "auto"

! U1 do "device.reset" ""
