The Sierra Radio Systems SIR-356 is a 5 port DCN data and power hub for the Sierra Station Controller range.
It is designed to expand the Sierra DCN, or Device Control Network, by providing additional connection points for compatible Station Controller modules. This makes it useful when building larger control systems with multiple GPIO modules, coax relay modules, watt meter modules, relay controllers, temperature sensors, and other Sierra accessories.
The SIR-356 is ideal for remote stations, repeater sites, contest stations, and shack automation installations where several Station Controller modules need to be connected in a tidy and organised layout.
Key Features
- 5 port DCN data and power hub
- Expands the Sierra Device Control Network
- Provides additional connection points for compatible Station Controller modules
- Helps distribute DCN data and power around a control system
- Useful for larger Sierra Station Controller installations
- Suitable for remote stations, repeater sites, and shack automation
- RJ45-style DCN connections for CAT5/CAT6 network-style patch cables
- Helps create a tidy modular station control layout
- Suitable for DIN rail, cabinet, rack, or panel style installations
- Works with the wider Sierra Station Controller module range
Typical Uses
- Expanding a Sierra Station Controller system
- Adding extra DCN connection points
- Connecting multiple control modules in one installation
- Remote HF station control systems
- Repeater site monitoring and control
- Shack automation projects
- Contest station control layouts
- Cabinet or DIN rail mounted station controller installations
- Tidying DCN cabling in larger systems
Station Controller System Role
The SIR-356 acts as a DCN expansion hub within the Sierra Station Controller system.
The Sierra DCN allows compatible modules to communicate using RS-485 based control data over RJ45-style cabling. The same cabling can also carry system power between compatible modules, helping to reduce wiring and simplify installation.
Although the connectors are RJ45 style and use network-style patch cables, the DCN ports are not standard Ethernet ports. They should only be connected to compatible Sierra Station Controller modules and accessories.
Power Requirements
The SIR-356 is part of the Sierra DCN data and power system. In many installations, power may be supplied through the DCN from a suitable Sierra host or powered DCN arrangement.
If the hub is being used to distribute power to other modules, or if the installation is not being powered through an existing SIR-310 host adaptor or powered DCN connection, a suitable external DC power source may be required.

Important Note
This listing is for the SIR-356 DCN Data and Power Hub only.
SIR-310 host adapter, installation kit, control modules, power supply, sensors, relays, coaxial cables, station equipment, and other accessories are not included unless stated otherwise.
A suitable external DC power source may be required when the hub is not being powered through a Sierra DCN connection from a suitable Station Controller host or powered DCN system.
The Sierra DCN uses RJ45 connectors and network-style cables, but DCN connections are not standard Ethernet connections. Do not connect DCN ports directly to normal Ethernet network equipment.
