The Solari Udine MCK 2245 is a modular microprocessor master clock (centrale oraria) designed for high-traffic environments like airports, railways, and hospitals. It serves as a central synchronization hub, managing traditional slave clocks via polarized pulse lines and more advanced devices through serial connections.
For detailed technical guidance, you can access the MCK Installation and Use Manual (PDF) provided by Studio Casartelli. Key Technical Specifications
The MCK 2245 is capable of complex timekeeping management with the following features:
Pulse Lines: Supports polarized pulses (unipolar or bipolar) with cycles of 1, 7.5, 30, or 60 seconds. Capacity: Max load of 24V/1.5A per line.
Connectivity: Includes an asynchronous serial line (RS 232/485) for sophisticated equipment. Solari Udine MCK 2245 is a professional-grade master
Automation: Features a perpetual calendar and automatic Daylight Saving Time (ora solare-legale) adjustments.
Reliability: Equipped with internal batteries to maintain the central unit and clock pulse drivers during power outages.
Control: Includes relays for managing external systems like acoustic signals or lighting. Operational Functions
Synchronization: Acts as the "brain" for centralized clock systems, ensuring all connected displays match the master time.
Software: Compatible with synchronization software for precise time management across networks.
Display: Typically used with industrial LED or flip-clocks from the Solari Spa catalog. Industrial Clocks - Solari Spa Chapter 5: Sourcing the MCK 2245 Manuale Work
Chapter 5: Sourcing the MCK 2245 Manuale Work
The original paper manuals are now rare. Solari Udine has since evolved into Solari di Udine S.p.A. (now part of the Solari Digital Solutions group). They do not typically support 1980s-1990s hardware anymore. However, here are three channels to find the PDF:
- Railway Enthusiast Forums: Italian forums like Ferrovie.it or Stazioni del Mondo often have scanned manuals in their download sections. Search for "Manuale MCK 2245."
- Industrial Surplus Auctions: When a station upgrades its timing system, the manuals are often sold in lots. Check sites like Industrial Surplus World or Ebay Kleinanzeigen (DE).
- Reverse Engineering Communities: Hackaday.io or EEVblog forums have users who have reverse-engineered Solari protocols. While not the official manual, they have created de facto work guides.
A note on authenticity: Beware of PDFs titled "MCK 2245 manual" that are only 2 pages long – those are user guides. A true Manuale di Lavoro is 40–80 pages, including fold-out schematic sheets.
7. Connector Pinout (DB25 – RS485)
| Pin | Signal | Description | |-----|--------|-------------| | 1 | GND | Ground | | 2 | TX/RX+ | Data + (RS485) | | 3 | TX/RX- | Data – (RS485) | | 5 | +5V | For external converter (max 100mA) | | 8 | BUSY | Output (open collector) | | 12 | RESET | Reset line (active low) | | 16-25 | NC | Not connected |
For RS232 (if equipped): use pins 2(RX), 3(TX), 7(GND).
5. Maintenance and Troubleshooting
The MCK 2245 is low-maintenance, but specific "manual work" is required if the display malfunctions.
Why the "Manuale Work" is Critical
Unlike modern network time servers (NTP), the MCK 2245 operates on proprietary voltage levels and pulse widths. Without the original manuale, guessing the terminal connections can destroy the output transistors or create feedback loops that damage the slave clocks. The phrase "manuale work" implies not just reading, but active intervention—calibrating potentiometers, replacing aging capacitors, and re-adjusting cam switches.
