 You could use HostNames, but I have found hostnames on Pi's pretty unreliable.

+==== Edit launchUMD File  ====
+\\
+The launchUMD file contains a link to the UMDisplay0x.py file
+\\
+<file>
+#!/bin/sh
+# launchUMD.sh
+# navigate to home directory, then to this directory then launch script
+cd /
+cd home/pi/Python
+sudo python UMDisplay01.py &
+cd /
+</file>
+\\
+This file needs to be edited so that the line <color blue>sudo python UMDisplay</color><color red>1</color><color blue>.py &</color> points to the correct UMD Device (so if this is your third UMD Device it needs to contain UMDisplay0<color red>3</color>
+\\
+    sudo nano launchUMD.sh

+==== Edit UMDsiplay0x File  ====
+\\
+The UMDisplay0x file contains the code to write to the LCD. We do have to edit this file to tell it which of the two LCD lines to display from the my_data.txt file
+\\
+<file>
+# write line 1 and 2 to the LCD
+lcd_string(" " + line1,LCD_LINE_1)
+lcd_string(" " + line2,LCD_LINE_2)
+</file>
+\\
+<color red>Line1</color> refers to the line in the <color red>my_data.txt</color> file. So if this was UMD3, then you would want lines 5 and 6. so this would be:
+\\
+    lcd_string(" " + line5,LCD_LINE_1)
+    lcd_string(" " + line6,LCD_LINE_2)
+\\
+<color red>LCD_LINE_1</color> refers to the Line on the LCD (Line 1 is the top, line 2 is the bottom)
+\\
+\\
+Edit the UMDisplay0x.py file by using:
+\\
+    sudo nano /home/pi/Python/UMDisplay0x.py
