Maximum Humidity: ≤ 90% (non-condensing)
Diagram shows the terminal block layout and power input specifications, including voltage ratings and environmental limits.
Wiring and Configuration
Cable Specifications
- Recommended cable size: 0.3-2.5 mm² (22-12 AWG)
- Recommended torque: 0.4 Nm (3.5 Lb-in)
- Maximum current per port: ≤ 2 A
Diagram indicates recommended cable sizes and torque settings for terminal connections.
Port Types and Configurations
The DDNG485 features two ports, Port 1 and Port 2, supporting various communication protocols:
- RS-485 DyNet Spur
- RS-485 DyNet Trunk
- DMX512
- And others (e.g., "etc.")
Diagram shows labels for Port 1 and Port 2, indicating support for RS-485 DyNet Spur, RS-485 DyNet Trunk, and DMX512.
Network Topology and Cable Length
The device supports different RS-485 network topologies:
- DyNet Spur: For shorter runs or specific device connections.
- DyNet Trunk: For main communication lines.
Maximum cable length for DyNet Trunk connections is up to 800 meters (≤ 800m).
Diagram illustrates DyNet Spur and DyNet Trunk configurations and indicates a maximum cable length of 800m.
Power Supply and Network Connection
The gateway can be powered by compatible controllers or a dedicated power supply unit (e.g., DDNP1501).
Connections are made to network devices.
Diagram shows the gateway connected to network devices and indicates power supply options from controllers or a DDNP1501 unit.
End-of-Line Termination
For cable runs exceeding 300 meters (1000 ft) or when using baud rates over 9600 bps, 120 Ω, 2 W end-of-line resistors are required.
These resistors must be installed across the D+ and D- terminals on the first and last devices in the communication chain.
Diagram illustrates the requirement for end-of-line resistors on long cable runs or high baud rates.
Regulatory Compliance
Federal Communications Commission (FCC) Notice
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Any modifications not approved by the manufacturer of this device could void the user's authority to operate this device.
Canadian Compliance
This Class B digital apparatus complies with Canadian ICES-003: CAN ICES-3(B)/NMB-3(B).
General Installation Standards
