Ty Johnson of Dakota Soft INC has a new Database driven translator for J1939 (and I assume NMEA 2000 soon). He also has a new module for J1939 isolated bus. Good prices on the these products. If you are a manufacturer... pay attention to DakotaSoft Inc. They have a good J1939 and NMEA value chain for ARM/PIC (most common processors) and skills in Keil. Good way to put products out. With low cost ARM chips (LM and ST) we can see this company taking off. Nice price on an NMEA stack.
Anyway the CAN module has some key features usually in higher priced units.... I bolded them.
High-speed CAN interface according to ISO 11898-2
Supports 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B active) identifiers Low power consumption, USB powered
Excellent EMC performance
Works with USB2.0 hubs Most don't
Quick and easy Plug&Play installation
Up to 64 USB-CANmodul devices can be connected via standard USB hubs for simultaneous use on a single PC
Supported bitrates: 10 to 1000 kbps
Optional galvanic isolation (no external power supply required) USB full-speed function device, USB 2.0 compliant, transmission type: bulk, 12 Mbps
CAN-bus interface connector: SUB-D9
Supported CAN transceivers: 82C251, SN65HVD23x, TLE6250G, TJA1050
LEDs for power-supply, CAN state and CAN traffic
CE conformity Power consumption type. 110mA, USB powered
Dimensions: 78 x 45 x 18 (LxWxH in mm)
Weight: 40g
Operating temperature: -40°C...+85°C Considering how much it costs to verify NMEA 2-5K , EMI test 3-5 K, design and develop many $K, and manufacture, DakotaSoftInc is worth a look as a stack supplier and partner. I know of what I speak.
When I get time, I'll write a NRZ wave decoder for my Tek DSO download, for the scope with time stamps. I'd like that to correlate that in real time for Canbus. On the order of
http://www.lecroy.com/tm...ary/LABs/PDF/LAB766.pdf app note. That way I check thoughly. Zigbee scopes, LeCroy, and Tek scopes do this with addins, but Fluke, Modis, and Picoscope do not. I may pick up the DakotaSoft product and feed it from the scope using an Octave program .... Yep need correlation.
Our good friends at Kvaser have a
wireless CANBUS connector and some new products. Very helpful and knowledgeable.
Unzinced ships sink at slips. yep
