Once you address the 6150 or 6160 keypad to "16" and activate *189 (a value of "1111" needs to be in this field in order for the touchscreen to work), you can program from the touchscreen (you needed the 6150 or 6160 keypad simply to be able to activate this field, which allows the touchscreen to function).
So, at this point, once you have the 6150 or 6160 addressed and working, follow these steps to enable the touchscreen:
1. Enter (4112) + (800) to get into programming mode.
2. Enter (*) + (189) (1111) to enable any touchscreen keypads.
3. Enter *99 to exit programming mode.
Now, power your touchscreen up. Once your touchscreen is powered up go to "console mode" and then enter (4112) + (800) and begin your programming, it will give you a full alpha display.
