Setting the termination
You must set the termination of the data signal in each dome (or device) to on or off. Only two of the four
switches (3 and 4) on the DIP switch block are used (
Figure 23 ). Switches 1 and 2 are not used at this time, so
it does not matter whether they are set to on or off.
Figure 23.Termination switches
To set the termination, do the following:
1. Set both termination switches to on if the dome or device is the final receiver location for the data
signal or if it is only device on the data signal bus.
2. Set both termination switches to off if the data signal needs to loop out to other domes or devices.
Note: The switches are set to off by default.
