SDM-500® is our most advanced 4.3” display logger which is also available with a built-in 20Hz GPS/Performance Meter. It has fully configurable CAN BUS, preloaded Smart Alarms, Auto-display Page Changing, a permanent Engine Log, 1-click Min/Max values function and the capacity to display up to 256 different ECU parameters. The 256MB internal datalogger lets users record up to 7.5hours and review the logged files also on the device. Comes with a 4D wired joystick and is compatible with most after-market ECUs and with OBDII.

With luminance 1,000 cd/m2 the 480 x 272 display looks very vivid and is easily readable in all light conditions and from various viewing angles. The multi-layer broadband antireflective coating decreases surface reflections drastically, whilst increasing light transmission and eliminating “ghost” imaging.
20Hz display refresh rate ensures a smooth, real-time-feel visual experience and lets you view exactly what is happening, the moment it is happening, with no delay in between
A sensitive light sensor at the front of the monitor enables adaptive display dimming to suit the light conditions and makes viewing better both in direct sunlight and low light conditions
7 auto-dimmable shift LED lights with configurable set point per gear as well as step distance per rpm (e.g. every 100rpm) ensure optimised gear changing
Smart Colour Coding
Configurable 3-level parameter colour-coding minimises distraction and communicates engine status easily with just a quick glance. How does it work? The user defines the low (BLUE), normal (GREEN) and high (RED) thresholds for each displayed channel and the SDM-500® colours it accordingly once the values hit that range. Your peripheral vision will then let you know almost instinctively when something is out-of-place and if it requires your extra attention.
Optimum Contrast, Saturation and Fonts
Instead of trying to impress with fancy realistic graphics, overly contrasted display items and ineffective fonts, we chose to implement the most effective combination of font type / size, colour palette and contrast levels that is derived from aviation dashboard design and colour theory studies. Priority is placed in having effective display items that require the minimum driver attention and achieve a “magnifying” effect making the SDM-500® come across as larger than just 4.3”.



The Auto Display Page Changing function allows you to keep your hands on the wheel and your focus on the track without having to manually switch among different page layouts. You only have to decide on the conditions and the parameters for 4 different display pages: “WARM-UP”, “RACE”, “ERROR” and “NORMAL” and once the thresholds are reached the SDM-500 will automatically switch to the respective page.
More than 10 different display layout pages to choose from, plus Pop-up displays, diagnostic, setup and statistics pages. All designed to offer best possible viewing ergonomics. Users can select to install the same layout many times but with different channels and name them accordingly.

Depending on your ECU’s capacity and the connected sensors, the SDM-500 can display up to 256 different channels among which are ECU status and error flags. Always be in the know of what’s going on inside your engine.
With just a single click on the SDM-Joystick of via the device’s side keys, you can view the minimum or maximum values of every displayed parameters and decide whether to maintain the value in memory or dismiss it and start counting again
Continuous Engine Log function that runs on the background and which keeps an independent log with max. values and histograms for key engine parameters such as RPM, MAP, ECT, OILT, FUELT, EGT1, EGT2 and the min. BATV.
20 pre-loaded Smart Alarms which only require that you input their trigger value reduce set-up time by more than 80%. Alarms will then appear superimposed in high contrast over the display page according to set priorities. A history of the last 100 alarms including their date, value and duration will be stored in a log for later retrieval on the PC SW.
A very accurate, accelerometer assisted, Performance Meter runs all the time in the background providing reliable measurements in different units/formats: 0-60mph, 60-120mph, 0-180mph, quarter mile (60ft, 1/8 mile, 1/4 mile with exit speeds), 1km/1mile with exit speeds and more. The always-on performance meter automatically saves 1/4 mile runs when top speed exceeds 100kph.
An upgraded 20Hz internal GPS module with ultra-fast start-up time (1-3 sec) and time-zone setting to auto-sync device time, enables accurate predictive lap-timing with section break down and raw data logging. The lap timing feature can be used on both open and closed circuits and can be driven by the GPS or CAN Bus data (e.g. ECU) or a track beacon signal.

Uniquely shallow total installation depth of just 19mm makes the the SDM-500 suitable also for OEM dashboards. Without any protruding wires and connectors from the back side, installation is quick and requires minimum effort.
Control your SDM-500® easily with the supplied wired joystick that is used for device set-up, menu browsing/page changing and controlling of the on-device data log review function. Being small and lightweight, yet ergonomic and rugged the joystick adds a new level of safety and convenience while you are driving
The SDM-500® comes equiped with an integrated 256MB datalogger that records up to 7,5hours and varying rates up to 100Hz . The logged files can be reviewed effectively on the device in 3 easy steps without the need for a PC. The on-device log-file reviewing provides reduced complexity, saves valuable time and brings unique convenience to a process that typically requires plugging in a PC and setting-up correctly the analysis SW.
STEP 1: SELECT LOGGED FILE

STEP 2: CHOOSE ANALYSIS DATASET

STEP 3: BROWSE & ZOOM-IN/OUT

8 user-defined math channels allow custom parameters to be calculated in real-time. Examples: break bias calculation, long-button hold detection, accumulated condition active time, and more.
Fully programmable CAN BUS for message receive lets you configure the display to collect information for almost any CAN Bus ECU or other device on the market. Configurable message transmit lets you control other devices such as PDMs or translate message to a different format as required.
