FAQ

Q: What network does this board interface with?
A: The 51400700-100 interfaces with the Honeywell Data Highway (DHI), a legacy peer-to-peer communication network used in TDC 3000 systems.

Q: Is this board required for all TDC 3000 systems?
A: It is only required if your architecture includes Data Highway communication. Pure LCN/UCN systems may not need it.

Q: Can this board be used for Modbus or Ethernet?
A: No, this is specifically for the Honeywell Data Highway protocol. For Modbus or Ethernet, use the appropriate gateway or communication module.

Installation Guide

1. Power down the chassis and observe ESD protocols.
2. Install the board in the appropriate chassis slot.
3. Connect Data Highway coaxial cables to the board terminals.
4. Configure Data Highway node addresses per the TDC 3000 configuration manual.
5. Power up and verify communication status via system diagnostics.

Selection Tips

• Verify that your system architecture actually uses the Honeywell Data Highway.
• Check cable type (coaxial) and termination requirements before installation.
• Ensure no duplicate node addresses exist on the Data Highway segment.
• Consider upgrading to UCN/LCN architectures for new installations.
