Engine Protocol Converter
Axiomatic has developed an electronic module designed to
act as an interface between CANbuses operating at different
baud rates and/or using different communications protocols.
The protocol converter incorporates two isolated CANbus
ports (SAE J1939, CANopen) and one Isolated RS485 port
(Modbus RTU/J1587) and can be used on a broad range of
mobile off-highway equipment, heavy-duty transport vehicles,
and gen-set control systems. The converter, which is connected through an integrated Deutsch IPD 12-pin connector,
is operational from 9 to 36 Vdc with 12 and 24 Vdc nominal,
and is configurable using the company’s Electronic Assistant
system. The unit is designed to be compact for easy integration into engine systems and utilizes a fully sealed, IP67 rated
housing for durability.
Woodward has redesigned its 2301D controller. The new,
drop-in replacement 2301E controller is backward compatible with existing 2301D products, including the same
footprint and mounting configuration, the company said.
Enhancements include: separate RS-232 and RS-422 serial
ports, both with 9-pin connectors; additional status LEDs for
power and RS-422 communications; fault data logging capability with 16 seconds of data collected every 10 milliseconds
in the event of a shutdown, peak speed and load detection; and a low-current PWM output for driving Woodward’s
L-Series, F-Series, P-Series and PISC actuators.The
2301E’s new terminal blocks accommodate additional I/O,
with a majority of the terminals located in the same position
as the 2301D models.
