NETBELL-ULTRA 300 QUICK SETTING INSTRUCTION

FIND THE IP ADDRESS ON YOUR NETWORK

The Netbell is DHCP enabled. When a Netbell SERVER unit is first installed on your network, it automatically obtains a web address from your router via DHCP, provided your router is configured to assign IP addresses. If your router is not set up this way, it is recommended to enable this feature to allow the Netbell SERVER to operate and to assign it a preferred IP address.

Several methods are available to find the Netbell IP address on your network:

RELAY CONTROL BELLS

Netbell devices use relay outputs to control bells. You can manually turn bells on/off or set their ringing duration by configuring the relays. To set relay properties, navigate to the Service -> In/Out (Relays) page.

The relay being edited is identified by the line where you clicked the Edit icon on the RELAY page. You can assign a name (up to 15 characters) to the relay (bell) on the Set Relay page.

The default Netbell pulse width is 4 seconds, meaning the bell will ring for 4 seconds per schedule. You can change this by entering your desired Pulse Width and Pulse Width Multiplier on the Set Relay page. You can also set different bell ringing durations for each schedule on the Bells scheduling page.

Note: When you set a duration on the Bells page for a specific schedule, it will override the relay's pulse width.

To test a bell after wiring it to a Relay Output, go to Services -> In/Out. Click the RED dot under the STATE column in the RELAY CONTROL section. When the RED dot turns green, your bell should ring. If it does not, please check the wiring.

SET TIME ZONE

Before scheduling your bells, it is crucial to set your Time Zone correctly. An incorrect Time Zone may cause bells to ring at the wrong times.

To set your Time Zone, go to Setting -> Time/Date page. Enter your local Time Zone value (e.g., -5 for Eastern Time Zone, -6 for Central Time Zone, -7 for Mountain Time Zone). Ensure the "Use NTP Update" box is checked; this will synchronize the Netbell's time with an NTP server every 30 minutes by default.

If your area observes Daylight Savings Time (DST), check the "Use Daylight Savings Time" box and set the DST start and end times. For an immediate time update, you can manually enter the standard time in the Time box (one hour behind your current time). Otherwise, the time will update during the next NTP interval. For example, if it is currently 9:35 AM, enter 8:35 AM.

Click the SAVE button to confirm your settings. You are now ready to schedule your bells.

Note: If you intend to use the Netbell as a standalone device after initial setup, uncheck the "Use NTP Update" box to prevent it from searching for an NTP server.

If DST is enabled, fields for "DST starts" (e.g., 2nd Sunday of March) and "DST ends" (e.g., 1st Sunday of November) appear. Other fields include "RTC Crystal Freq.", "NTP Web Site" (e.g., time.nist.gov), and "NTP Interval" (e.g., 30). Buttons for "Log NTP Event", "Save", and "Cancel" are present.]

ADD BELL SCHEDULES

You can add up to 10 sets of schedules to the Netbell-Ultra 300 controller, supporting regular schedules, teacher workdays, and holiday schedules.

To add a schedule, go to Services -> Schedules page. The system includes a default schedule named "Schedule 1", which is currently in use. You cannot delete this default schedule until you add a new one.

In the "Add" section at the bottom of the Schedules page, enter a schedule name (maximum 15 characters) and a description (maximum 32 characters), then click "Add".

[Screenshot Description: A "Schedule Selection" table within a web interface. Columns include "Schedule #", "Schedule Name", "Description", and "Use". Sample schedules listed are "Regular", "Longday", "Shortday", "Teacherwork", and "Holiday", each with a "DEL" button. A section below allows entering "Schedule Name" and "Description" to "Add" a new schedule.]

To switch between schedules, click the RED dot under the "USE" column for the desired schedule. The dot will turn GREEN when the schedule is active.

ADD BELL EVENTS

You can add up to 500 events for each schedule. Ensure a schedule is selected before adding events.

To add an event, go to Services -> Bells page. The "add bells" section is at the bottom of the page.

• Name: Up to 15 characters, no special characters.
• Time: 24-hour format (HH:MM:SS).
• Date: If selected, the bell rings only at this specific time and date. The day of the week is disabled when a date is used.
• Duration: Enter a number from 1 to 99, and select a length (milliseconds, seconds, or minutes). If left empty, the bell rings for 1 millisecond by default.

After clicking "Add", your first schedule will appear. By default, Bell 1 and Bell 2 are selected for Monday to Friday (M T W T F). To change selections, click the dot under the desired Bell or Day; it will turn GREEN to indicate selection (otherwise it remains GREY).

[Screenshot Description: A "Bells" table within a web interface, showing "Schedule 1 Ready". Columns include "No.", "Name", "Time", "Bell" (with day selections M, T, W, T, F, S, S), "Date", "Dur", "PW", "Use", "Once", and "DEL". Sample entries show times like 07:00:00 for "Morning", 08:00:00 for "8AM", with default durations and day selections. A section below allows entering "Name", "Time", "Date", and "Duration" to "Add" an event.]

DOWNLOAD & UPLOAD BELL EVENTS

You can save a copy of your current bell events or edit them for use with other devices or schedules using the Download & Upload function.

Download Bell Events:

1. Go to Services -> Bells page and click the DOWNLOAD button. A new window will open displaying your created events, starting with the #Start command.
2. Create a text file (.txt).
3. Copy the bell events into your text file, ensuring the #Start command is at the very beginning.
4. Save the file.

Edit Bell Events:

You can edit existing events by modifying the .txt file and then uploading it to other schedules or devices.

Understand the Netbell Event Template:

The bell template must always begin with the #START command. The order for the schedule entries is as follows, separated by commas:

NAME (max 15 chars), HH (2-digit, 24hr), MM (2-digit), SS (2-digit), YY (2-digit), MM (2-digit), DD (2-digit), BELLS (1-8), DOW (Sunday-Saturday), DURATION (1-99), DURATION MULTIPLIER (Ms, Sec, Min), USE (1-digit), ONCE (1-digit)

• NAME: Any words, max 15 characters.
• HOUR (HH): 2-digit number, 24-hour format (e.g., 15 for 3 PM).
• MINUTE (MM): 2-digit number.
• SECOND (SS): 2-digit number.
• YEAR (YY): 2-digit number.
• MONTH (MM): 2-digit number.
• DAY (DD): 2-digit number.
• BELLS: Indicates which bells to schedule (1-8). Use "1" for a bell to be scheduled, "0" for not scheduled. For example, for a Netbell-4, scheduling all bells would be 11110000. The Netbell-Ultra 300 supports bells 1-2.
• DAY OF WEEK (DOW): Indicates the day for the bell ringing, starting with Sunday (0) to Saturday (6). Use "1" for the desired day, "0" for not. Example for Monday to Friday: 0111110.
• DURATION: How long the bell should ring (1-99).
• DURATION MULTIPLIER: Ms, Sec, or Min.
• USE: "1" to put the schedule in use, "0" for not in use.
• ONCE: "1" to use the schedule only once, "0" for normal schedule use.

[Text Block Description: A sample text file content is shown, starting with "#Start" followed by lines of event data. Each line represents a bell event with comma-separated values for name, time, date, bell assignments, duration, and other parameters. For example: "Morning,07,30,00,00,00,00,10010000,0111110,5,Sec,1,0". A header row shows the expected format: "Name HH MM SS YY MM DD Bell 1-8 Day Dur Use Sun-Sat DM Once".]

Upload Bell Events:

To upload a .txt file to Netbell-Ultra 300, first select the schedules you want to apply the events to. Go to Services -> Bells page, click the Upload button, browse for your created file, and press Upload. Your events will then appear on the Bells page, with a count of uploaded records.

If you need to make changes after uploading (e.g., change which bell rings on specific days), click the pips to check/uncheck, then click SAVE. To delete a schedule, use the DEL button next to an event. To delete all events, use the Reset button.

USE NETBELL AS A STANDALONE DEVICE

It is strongly recommended to connect the Netbell to your network to ensure accurate time synchronization from an NTP server. However, if the Netbell is installed in a location without network access, it can be used as a standalone device.

To use it as standalone: after initial setup, go to the Time/Date page, uncheck the "Use NTP Update" box, and click SAVE. The Netbell will then operate using its internal clock and your set schedules.

If you notice the Netbell's time drifting (running faster or slower) over time when used as a standalone device, you can adjust the Real Time Clock (RTC) Crystal Frequency value on the Settings -> Time/Date page.

Adjusting RTC Crystal Frequency:

For example, if your current RTC Crystal Frequency is 32769.8 and you are losing one second per day, increase the frequency to 32769.9. If the clock is one second fast per day, decrease it to 32769.7. Make small adjustments (1-2 seconds) at a time and monitor the results.
