The Commander II is a compact, proven, rugged data logging device designed to be mounted in racing vehicles or used with engine dyno's.
The Commander II available with anywhere from 3 to 38 channels, and with memory options which include internal memory (with serial transfer to PC) and removable memory cards for instant download.
Complete systems including all sensors and cables are available from CDS, custom tailored and built to your exact needs.
12 Bit (.02%) Resolution:
- 4 times more accurate than competing 10 bit systems
- Easily measure very small differences from run to run
Commander II Models Are Upgradeable
- Add channels, memory, or options Any Time
- Commander II is Expandable, Not Expendable
Flexible Configuration Puts You In Control
- User definable recording mode, including channels to sample, recording rate, resolution, and engineering scaling units for each channel. Recording modes are saved for future re-use.
- Multiple simultaneous sample rates enable maximization of recording time for a given memory size.
Same State-Of-The-Art Software For All Systems
- Unlike other systems, all CDS systems use the same user interface, simplifying your learning curve when advancing up the racing ladder.
Removable Memory Card Option:
-
Eliminate download
time
- Eliminate necessity for connecting a cable to the vehicle
- Enable easy data transfer to multiple PCs
PC Requirements & Recommendations
- IBM Compatible with Windows 98 SE, 2000, or XP, 1024x768 (XGA) graphics recommended, 32 MB or more RAM recommended.
- Pentium II, III, IV, Celeron, or higher recommended.
- Type II or III PCMCIA slot required for memory card option
- Compatible RS232 COM port for communication
- Any Windows compatible printer (for hard copy)
Circle Track &
Road Race Operation
- Trigger switch starts the
recording in manual mode. If AUTORECORD is on, then recording starts
when the car reaches a user definable speed (in MPH or KPH).
- Each time the car passes the
photo beacon, the lap time is recorded and saved. Lap time is also displayed
to the driver with the optional driver’s display.
- Data is retrieved via removal of the memory card or connection to a PC using the download cable.
Drag Race
Operation
- Trigger switch starts the recording. Auto Launch Detect marks the data at the start of the run by detecting the first movement of the driveshaft. This enables Track Master 2000 software to overlay runs with the exact same reference, making comparisons from run to run easy.
- Data is retrieved via removal of the memory card or connection to a PC using the download cable.
Dyno Operation
- Commander II transmits data to Command-View software running on PC. Software Run Triggers automatically separate the dyno run from the warmup and cooldown data. This enables Track Master software to overlay runs with the exact same reference, making comparisons from run to run easy.
- Auto update in Track Master automatically plots your run as soon as it is finished.
