Powerline is a connectivity method allowing Ethernet to be modulated on a 3-pin shielded XLR cable providing multiple devices on the line with power and network communication. Powerline may be split, daisy chained and otherwise distributed passively over traditional XLR infrastructure to provide various installation options.


Powerline Device

The HelixNet powerline device bridges Ethernet to Powerline and provides an injection of power for the devices on the Powerline. Using the powerline device HelixNet user stations, operating on compatible firmware versions, can connect to their paired HelixNet system host, such as the Arcadia Central Station or HelixNet HMS-4X1 main station, via the system host’s network interface.

HelixNet powerline device supports up to (7) HelixNet beltpacks or its power equivalent HelixNet remote and speaker stations. HelixNet beltpacks can be daisy chained using the optional SP-2 intercom splitter cable, or equivalent passive splitters.

HelixNet powerline device can be located anywhere on the network it is optimal to connect the powerline within the cabling infrastructure. Multiple powerline devices can be on the network, providing the appropriate user station capacity and quality of service required for the installation.

HelixNet powerline device includes simple indicators for device local troubleshooting of up-and-downstream cabling and overload conditions, while centrally the Arcadia Core Configuration ManagerTM (CCM) accessible by any web browser), displays connection status and diagnostics information for all powerline connected devices.

Installation Options

The HelixNet powerline device is designed to allow for various installation options in different environments. Compact portable form-factor allows for the device to be placed or mounted wherever needed. Supplied rubber feet can be installed on the bottom of the device to allow for “throwdown” style usage. Optional SM-100 surface mount allows the powerline device to be permanently installed with screws, straps or using 3rd party DIN rail clips. Optional RK-100 19” rack mount allows up to (4) HXII-DPL powerline devices to be mounted in 1 rack space. Heavy duty industrial Velcro is provided for optional installation of the external inline power supply.
