(Optional) Add a U60 or U70 LON Network Interface and Router

LON is supported for SmartServer Pi 4.3 and higher, with the exception of LON PL.

If you will be communicating with any LON devices using FT or TP-1250 twisted-pair channels or a power line (PL) channel, add a LON network interface as described in this section.

You can add an external LON USB interface to communicate with any LON FT, PL, or TP-1250 devices. Up to eight external LON interfaces can be added with a maximum of:

  • Four U60 FT interfaces if you are not using LON power line repeating
  • One U60 TP-1250 interface if you are not using LON power line repeating
  • One U70 PL-20 interface if you are using LON power line repeating, or four U70 PL-20 interfaces if you are not using LON power line repeating

To add an external LON USB interface, connect the LON USB interface to one of the USB host interfaces on the SmartServer IoT using a USB Micro-B to USB A host cable.  Connect the USB Micro-B connector to the USB port on the U70 PL, and then connect the other end to a one of the four USB ports on a SmartServer IoT.  If you have more than four USB devices to connect to a SmartServer IoT, connect a powered USB hub to one of the USB ports on the SmartServer IoT, and then connect the devices to the hub.

You cannot install more than a total of five network interfaces (U60 or U70) and IOX modules in a single SmartServer. If you have five total, or if you have four and require a spare USB port, use a powered USB 3.0 compliant hub and plug all the U60 and U70 network interfaces into the hub. Always plug any IOX modules directly into the SmartServer and do not plug them into a hub.

If you are using multiple U60s or U70s (without power line repeating), for the initial installation power up your SmartServer before plugging in all but the first U60 or U70.  After your first startup, plug in each additional U60 or U70 one at a time. 

The following LON USB interfaces are available for the SmartServer IoT:
