Manual:LCD TouchScreen

Applies to RouterOS: v5.19+

Summary

Sub-menu: /lcd
Package:

RouterBOARD 2011U and CCR series devices are equipped with a resistive touchscreen, for quick access to device stats and simple configuration options. LCD can be protected with a PIN code. Touch screen requires pressure against the surface to register a touch, therefore light swipes and quick/short taps might not get registered (as opposed to a capacitive touchscreen commonly found on phones).

Configuration

LCD Touch screen can be controlled from the /lcd console menu.

Available properties:

• enabled - Turn the lcd off (backlight) (yes/no);
• backlight-timer - time after which lcd display is turned off (value range [5m;2h] / never);
• reset-calibration - start the calibration process;

LCD Touch screen Calibration

Before the LCD touch screen can be used, it needs to be calibrated at least once. After the first successful calibration, data is stored on the router. If no calibration values are present, calibration process will start automatically.

During the calibration you must touch 4 points drawn on the screen. Three of the points are used to calculate calibration variables and the 4th point is used to test whether the calibration was successful. If calibration is unsuccessful, calibration variables are not saved. At the end (after touching 4th point) a message is displayed with the calibration result.

LCD screens/modes

Graph Screen

Graph screen shows single interface graphs for RX and TX. Values are updated from right to left (newest to oldest). Info that is shown: RX/TX rate, packets, drops, errors.

Interface name is shown at the bottom right, it is trimmed if it's too long (last characters are cut off). The top right corner shows the time interval for the values. Following time values are available:

• Min (Minute) - shows values for the last minute. Unit = second. Vertical line separates first 30 seconds. Total values: 30 + 24;
• Hour - shows values for the last hours. Unit = 5 minutes. Vertical lines separate 1 hour. Total values: 12 + 12 + 3;
• Daily - shows values for the last days. Unit = hour. Vertical lines separate 1 day. Total values: 12 + 12 + 3;
• Weekly - shows values for the last weeks. Unit = day. Vertical lines separate 1 week. Total values: 7 + 7 + 4;

Motions:

• Tap - tapping the finger against the touch screen without moving it too much.
  • If a tap lands into the top right corner of the screen (square box 1/4 of the screen height), info time interval is changed: Min -> Hour -> Daily -> Weekly -> Min...
  • Otherwise a tap cycles through graph info: rate -> packets -> drops -> errors -> rate...
• Swipe/Drag - while holding the finger down, move in any direction. The changes should be highlighted during the drag.
  • Down - Select All Interface graph screen
    • Left - Next interface
    • Right - Previous interface

All interface graph screen

All interface graph screen shows single info (RX or TX Rate, packets, errors, drops) for all interfaces. Values are updated every second. The goal of this screen is to see how values are related to each other for a single interface.

Motions:

• Tap on the top left corner changes TX/RX.
• Swipe/drag changes are highlighted.
  • Up - Back (to Graph screen).
  • Left/Right - select info type: Rate, Packets, Errors, Drops.
