Appendix I - Powering the Nexus
This step is used for replacing or installing a new Nexus only.
When the Nexus has power applied to it, it will go through a process to establish communication
and to identify all inputs and outputs. When the process is completed, communication to all input
and output devices can be verified.
Utilize the following steps to correctly star tup the Nexus.
1. Verify Option Dip Switches 1 - 7 are in the OFF position, if the Inputs are being used.
If the Inputs are not being used, Option Dip Switches 1 - 8 need to be in the OFF position.
2. Bring power to the Nexus. The system will take a moment to boot up.
3. The LED “hear tbeat ” will begin flashing. This is the verification that power has been correctly
brought to the Nexus.
Appendix II - Discovery Mode
Discover y Mode is used to enable the Nexus to discover attached devices, repor t the addresses of
discovered devices, and save the configuration in the Nexus memor y.
Discover y Mode is also used after enabling Contact Closure Switches, installation of any new
devices to the system, or after the initial powering up of the Nexus.
Use the following steps to correctly utilize Discover y Mode.
1. Turn ON Option DIP Switch #7.
2. Press the Discover y/Clear button for one second. The Nexus “hear tbeat ” will turn OFF.
The communication LED next to the Firing Card por t will turn on. Allow several seconds to
complete the discover y of all connected input and output devices.
3. Discovered input addresses will light up the corresponding LED in the STATION section on the
programming inter face. Verify that all inputs are discovered at the correct address.
4. Discovered output addresses will light up the corresponding LED in the BOARD section on the
programming inter face. Verify that all outputs are discovered at the correct address.
5. To exit Discover y Mode, turn OFF Option DIP Switch #7. All the LEDs will turn OFF and the
Nexus “hear tbeat ” will flash. This will save the discovered configuration.
Appendix III - Clearing the Programming
Use the clearing the programming diagram to clear the programming on the Nexus. This clearing
will not clear out cer tain configuration parameters, such as the baud rate(s).
1. Press and hold the ‘STATION’ button. After a few seconds, the LEDs in the ‘STATION’, ‘INPUT ’,
‘BOARD’, and ‘OUTPUT ’ columns will light up.
2. As the ‘STATION’ button is held, the column LEDs will light in sequence, star ting at the
bottom and move towards the top. After the top LEDs light up, all of the LEDs will clear
and this indicates that the programming is cleared.
3. Release the ‘STATION’ button.
