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 22 ). Switches 1 and 2 are not used at this time, so
it does not matter whether they are set to on or off.
Figure 22. 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.
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. If this is the only device on the data signal bus or the last in a chain of
devices on the bus, then you need to switch them on .
