Prerequisites

JudoManager Desktop requires a stable and reliable environment to ensure smooth operation during competitions. This includes appropriate hardware and network setup.

Computer Requirements

JudoManager Desktop application (server computer):

  1. ✅ Windows 10/11 (64-bit), fully updated
  2. ✅ Local admin rights for installation
  3. ✅ CPU: Intel i5 processor (2 GHz or faster)
  4. ✅ RAM: Minimum 8 GB (16 GB recommended for multi-mat/events)
  5. ✅ SSD disk
  6. ✅ Updated .NET environment (usually pre-installed on modern systems)
  7. ✅ Suggested 15' display

Computers for modules (Scoreboard, Weigh-In, Accreditation, etc.):

  1. ✅ Windows 10 or newer
  2. ✅ Local admin rights for installation
  3. ✅ CPU: Intel i5 processor (2 GHz or faster)
  4. ✅ RAM: Minimum 8 GB
  5. ✅ SSD disk
  6. ✅ Updated .NET environment (usually pre-installed on modern systems)
  7. ✅ Suggested 15' display

It is advised to use dedicated computers with up-to-date Windows, free of viruses, unnecessary software, and background services that could impact performance.

Network Requirements

  1. ✅ Topology: All module PCs must be on the same LAN as the Desktop PC.
  2. ✅ Wired first: Wi-Fi is supported, but cabled connections are strongly recommended, especially for Scoreboards. If using Wi-Fi, prefer 5 GHz.
  3. ✅ IP addressing: Set a static IP on the Desktop PC. Module PCs can be static or DHCP.
  4. ✅ Firewall: Allow or add exceptions for JudoManager services (Scoreboard/FairReplay/UDP).
  5. ✅ Time sync: Ensure all PCs use the same NTP source (clock differences can cause sync/log issues).

The system depends on a stable local network. All module computers must be connected to the same network as the one running the JudoManager Desktop application.
Ensure the firewall is either disabled or set to allow exceptions for JudoManager.

Info
A local network can be created using a switch or router. Wireless connections are supported but cabled connections are strongly recommended, especially for the Scoreboard module.

Additional Recommendations

  1. ✅ Disable or close unnecessary programs and services (e.g. Skype, antivirus tools) to avoid system slowdowns.
  2. ✅ Make sure the server computer has a static IP address. Other module computers can have either static or dynamic IP addresses. (See article Network setup for sample IP configuration.)
  3. ✅ If using Wi-Fi, a 5 GHz connection is preferred due to reduced interference and higher stability.
