Sierra Radio Systems Station Controllers
Sierra Radio Systems Raspberry Pi Host Adaptors
Sierra Radio Systems Raspberry Pi Host Adaptors are the brain of the station controller system. Featuring a Raspberry Pi™ 3 running the Node Red Station Controller flow, simply plug your modules into the RJ45 ports on the controller board, apply power to any board and the system is ready to go. Power is supplied by attaching power to either the power pole connection or the 2.5mm plug and power can be applied to any board in the system. Three RJ45 jacks provide connection and power to the other modules in the system, and you can add modules as you need them. There is an optional Heltec v3 LoRa radio module to be able to control over the air, but this is not a requirement for full station control operation. The SIR-310 comes with: • The Raspberry Pi Adaptor board with built-in power supply and DCN hub • Raspberry Pi 3 single board computer • SD card with the latest operating system and Node Red Station Controller flow NOTE: At least one module is required for the Raspberry Pi Host Adaptor to be able to control devices in the shack.

Sierra Radio Systems General Purpose Input/Output (I/O) Modules
Sierra Radio Systems General Purpose Input/Output (I/O) Modules are the heart of the Station Controller system allowing the user to turn station power on and off, control power to ancillary devices, measure voltages and equipment temperatures. Featuring a total of 18 I/O channels to control and monitor a variety of items within the shack. The various I/O includes: • 4x 0-50 Vdc volt meters, ground referenced. • 4x SPST Built-in relays capable of switching up to 2A • 4x Open collector outputs for external 12 volt relays or 'Pull to ground" activated devices. • 4x Optoisolated digital inputs for door alarms, band decoders, etc. • 2x Digital Temperature probes, available on 3 ft. and 6 ft. cables

Sierra Radio Systems RF Watt Meter Modules
Sierra Radio Systems RF Watt Meter Modules are an addition to the Station Controller Modules. The module, in conjunction with 1 or 2 active RF power monitoring sensors, provides multiple modes of measurement. Using the Node Red Station Controller Workflow the user can select between periodic measurements, streaming data (with less than 1 second of refresh), and remote repeater keying. Using any combination of the HF-1, LP-1 and UHF-1 RF sensors, which are supplied by WaveNode, the module will provide RF sampling up to the power level of the specific sensor. NOTE: This module requires at least one RF sensor that are supplied by WaveNode. These can be purchased directly from WaveNode at https://wavenodedevelop.com

Sierra Radio Systems Remote Coax Switches
The Sierra Radio Systems Remote Coax Switches are designed for ease of remotely switching the antennas using the Node Red Station Controller Flow. Designed for a maximum power rating of 100 watts, and covering the 1 to 60 MHz frequency range, the insertion loss on the HF bands is less than .05 dB and port isolation is between 53 and 65 dB across the HF Band. Latching relays will maintain the position of the switch if power is removed from the module. When the module switches the antenna, it releases the current connection prior to making the new connection. Built in firmware prevents any two relays from being active at the same time and all relays could be put in a disconnected state. A terminal block at the top of the module provides 4 momentary pull to ground inputs to allow external pushbutton control or electronic switching to select the active antenna. Two modules may be connected via the common port, allowing for a 4 x 4 switching arrangement where any one of 4 antennas could be connected to any one of 4 radios. Additional Feature and Specifications: Max power limit: 100W Frequency range: 1-60 MHz
