2.5 Dallas 1-Wire Bridge

In addition to the six general purpose outputs the LK204-25 offers an optional Dallas 1-wire bridge, to

allow for an aditional thirty two 1-wire devices to be connected to the display. Please note that the display

normally does not come with the Dallas 1-wire bridge. It will have to be ordered as a custom. Please talk to

your sales representative if you would like this option. See Section 8 on page 33.

2.6 Manual Override

The Manual Override is provided to allow the LK204-25 to be reset to factory defaults. This can be

particularly helpful if the display module has been set to an unknown baud rate or I

C Slave Address and

you are no longer able to communicate with it. If you wish to return the module to its default settings you

must:

1. Power off the display module.

2. Place a Jumper on the Manual Override pins.

3. Power up the display module.

4. The display module is now set to its default values listed below in table 1.

5. Edit and save settings.
