Part# 13-20702
MFR Model# SMT555-101


The smartLink 555 is a Flight Data Recorder, Pulse Oximeter, CO Detector, and AHRS that works with the Guardian Avionics smartPlane system. This unit is panel mounted in a small position to provide convenient access to the Pulse Oximeter in-flight. The smartLink 555 communicates with the smartMFD iOS app via Bluetooth connection.

Start with the CO Poisoning Prevention that Guardian Avionics is Known For.
The smartLink 555 is built around the reliable and accurate Carbon Monoxide detection technology that Guardian Avionics and CO Guardian has been known for. The sensitive onboard CO sensor alarms an initial warning when CO levels measure greater than 50 parts-per-million (PPM) up to 99 PPM. A persistent warning will trigger when levels climb above 99 PPM immediately when detected.

Prevent Hypoxia with Built-in Pulse Oximeter.
The smartLink 555 allows the pilot and crew the ability to measure blood oxygen levels (O2 saturation) and pulse in-flight from the convenient panel-mounted pulse oximeter. For pilots flying at higher altitudes regularly, the smartLink 555 is a convenient option to help prevent hypoxia.

Avoidance of hypoxia at higher altitudes is important to pilots – lower blood oxygen levels could result in physical impairment, unconsciousness, and even death if not accurately monitored. Even while using supplemental oxygen, measurement of blood oxygen levels is important to assure the effectiveness of O2. The highly sensitive built-in pulse oximeter in the smartLink 555 measures the blood oxygen level and pulse (heart rate) of the pilot or crew member when the index finger is inserted into the unit. Measurement takes only seconds and will display on the smartMFD iOS app and select 3rd party avionics products.

Your GPS, Engine Monitor, and Attitude Connect & Display on Your iPad & iPhone.
The smartLink 555 can be connected to your onboard GPS and Engine Monitor via RS-232, allowing accurate navigation and engine performance data to be aggregated, transmitted, displayed, and recorded on your iPad and/or iPhone through the Guardian Avionics smartMFD app via a Bluetooth connection. The smartLink 555 also has a built-in AHRS (Attitude and Heading Reference System) for VFR use that will prove attitude data to the iOS. As a result, your iPad and iPhone become mini-multifunction displays -- fully equipped with accurate VFR and IFR maps and charts, rich graphical engine performance information, and even a mini-PFD/MFD for quick reference. All Carbon Monoxide alerts and levels are also available on the smartMFD app too!

All Your Flight Data is Sent and Stored in the smartData Web App for You.
Through the smartMFD app, all of your flight data is stored and uploaded to your account on the Guardian Avionics smartData web app via 3G/4G/LTE or WiFi at the end of every flight, with the ability to download and view flight tracks on programs like Google Earth, view engine data through rich charts and graphs, and even export your data for use through other programs or to send to others. If your iPad or iPhone is connected to your audio panel through a 3.5 mm audio jack, the app will even record the audio from your intercom and upload it to your account for each flight too!

How can you use the data? See how accurate your recent practice approaches were on a recent flight. Send trend data to your A&P or engine manufacturer to troubleshoot an issue. Evaluate all aspects of a recent training flight, including radio procedures.

Budget and Panel Space Friendly.
Equipping the smartLink 555 is like bundling multiple pieces of equipment into one compact, panel mounted unit. In the past you’d need to buy and install a CO detector, Pulse Oximeter, GPS signal booster, and backup AHRS for your iPad/iPhone as separate items – and flight data recording on an app for both navigation and engine data was not even available! Now you can get all of that in one small, easy to install package for one reasonable price!
