iCatcher Scoreboard Support

Requirements

• Scoreboard controller powered on
• Your phone connected to the same WiFi network as the scoreboard
• Scoreboard controller IP: 192.168.1.252 (factory default)

Steps

Go to Settings → PIXEL SIZE OF SCREEN and enter your scoreboard's physical pixel dimensions. This affects how text chunks are split across RAMT slots.

• Width: 32–512 px (typical: 128 or 256)
• Height: 16–256 px (typical: 64 or 128)
• Enable Ultra-wide if your display is double-width — doubles characters per slot.
• Enable Single Colour for monochrome red displays — overrides all colour settings.

On any scoring screen, locate the Team Names card. Tap the text field for Home or Away and type the team name. Changes are sent to the scoreboard immediately and saved permanently.

• Tap the ⚙ icon (left of "Team Names") to adjust text size, colour, alignment, and vertical position.
• Names survive sport changes and 12-hour auto-resets.

Basic controls

• ▶ / ⏸ — Start / pause the timer
• ⏹ — Stop and reset
• Set Time button — Enter a specific time (MM:SS)

Timer direction

• Count up — starts at 00:00, counts upward
• Count down — set a target time (e.g. 20:00), counts down to 00:00

Tap the ⚙ icon to change display size, colour, alignment, and the Shift to Right (leading spaces) setting.

The shot clock card appears on Basketball and Hockey scoring screens. It operates independently from the main timer.

• Tap Set Time to enter a custom shot clock duration.
• Use ▶ / ⏸ to start and stop.
• Tap ⏹ to reset to the default duration.

The AFL screen shows separate buttons for Goals and Points for each team. The total is calculated automatically.

• Goals are worth 6 points each.
• Points (behinds) are worth 1 point each.
• The Quarter widget lets you set the current quarter (1–4).
• Tap ⚙ next to "Quarter" to style the quarter display on the scoreboard.

The Cricket screen has individual counters for each stat. Use + / − to adjust each field:

• Runs — home and away team run totals
• Wickets — wickets lost (0–10)
• Extras — wides, no-balls, byes, leg-byes
• Overs — current over count

If the app has not been used for more than 12 hours, all live game scores are automatically reset to zero the next time the app opens.

• Scores reset: all sport scores, timer, timeouts, fouls, etc.
• Not reset: team names, styles, settings, ads, configurations — everything else is preserved.
• The 12-hour clock resets every time you use the app, so mid-game sessions are safe.

From the ADVERTISEMENTS card on the scoring/manage screen:

• Select which ads to include by tapping them (they highlight when selected).
• Tap "Play Ads" — the scoreboard cycles through selected ads.
• Tap "Return to Scores" to switch the scoreboard back to the current sport layout.

In Laptop Mode, advertisements are fixed slots Ad1–Ad5 that correspond to pages pre-programmed in iCatcher Laptop software. Each ad slot has:

• Duration — how many seconds to show this ad before cycling to the next
• Enable/Disable toggle — include or exclude this slot from the rotation
• Custom name — tap the ✏️ icon to rename each slot (e.g. "Sponsor 1")
• Page mapping — configure which scoreboard page each ad switches to (see Page Mapping section)

Laptop Mode is for setups where an iCatcher Laptop computer is the primary controller of the scoreboard's display. In this mode:

• The app sends counter commands to the hardware counters — iCatcher Laptop reads these and updates its own display.
• The app sends hardware timer commands instead of software special area timer sends.
• RAMT slot assignments are irrelevant — the laptop handles layout.

Page Mapping lets you configure which scoreboard page each sport and ad slot switches to when selected.

Sports

• Options: — (none), 0–6
• — = don't send a page switch when entering this sport
• Default: all sports → page 0

Advertisements (Ad1–Ad5)

• Options: — (none), 0–10
• — = don't switch pages when this ad slot plays
• Default: Ad1→1, Ad2→2, Ad3→3, Ad4→4, Ad5→5

Tap Save to apply. Tap Reset Defaults to revert to factory settings.

Remapping Mode allows you to reassign which hardware counter slots and RAMT display slots each field uses.

Enabling

Counter Channels (Counter Commands)

Assigns which hardware counter slot (1–6) receives each score value. Select the channel number next to each field name.

Special Area Display Slots (normal mode only)

Assigns which LED board display slots (1–8) each element occupies. Every position can be set independently — they do not need to be consecutive.

• Home/Away Team Name: 2 slots each (Part 1, Part 2)
• Timer: 3 slots (Slot 1, Slot 2, Slot 3)
• Shot Clock / AFL Quarter: 1 slot

Timer Channels (laptop mode only)

Select which hardware timer channel (Ch 1–4) drives the game timer and shot clock.

Settings → ADVANCED → UDP Timing

Command Delay

The gap between consecutive UDP commands sent to the scoreboard. Lower = faster. Default: 120 ms.

• Reduce if you want faster score updates
• Increase if you notice commands being dropped or out-of-order
• Use the slider (0–120 ms) or type any value directly in the text field

Boot Init Delay

How long the app waits after zeroing counters before sending real scores when entering a sport screen. Default: 500 ms.

• Increase if you see random old numbers flash briefly when opening a sport
• Decrease or set to 0 to skip the delay if your hardware is fast

Settings → scroll to bottom → "Reset All Settings"

Check these in order

This is caused by the scoreboard still showing counter values from a previously used sport. The app zeroes all counters first and then sends the correct values, but if your hardware is slow you may see a brief flash.

Fix

Go to Settings → ADVANCED → UDP Timing and increase the Boot Init Delay (e.g. from 500 ms to 800–1000 ms). This gives the hardware more time to process the zeroing before real scores are sent.

• Wrong display size: Go to Settings and verify Width × Height match your board's actual pixel dimensions.
• Text size too large: Tap the ⚙ gear next to the Team Names or Timer widget and reduce the size setting.
• RAMT slots overlap: If you've customised slot assignments in Remapping, ensure no two elements share the same slot numbers.
• Ultra-wide not enabled: If your board is double-width, enable Ultra-wide in Settings.

• Check connection: The green "Connected" banner must be visible on the home screen. If not, reconnect.
• UDP queue: Commands are queued and sent one at a time with a small delay between each. This is normal — the scoreboard hardware processes them sequentially.
• Reduce command delay: Settings → ADVANCED → UDP Timing → lower the Command Delay slider toward 0 ms.
• WiFi congestion: Move closer to your WiFi router or switch to a 5 GHz band if available.

From v1.1.0 onwards, all data is saved in two locations on your device:

• Primary: A JSON file in the app's documents directory — survives all app updates indefinitely
• Backup: SharedPreferences — legacy location, also survives updates

If you're on an older version and upgraded, the app automatically migrates your data from the old location to the new one on first launch.

Demo Mode lets you use all app features without a physical scoreboard. Commands are still built and would be sent, but no hardware is required.
