Gateway 3 (CAN/LIN/J1850
Gateway)
DGE's
Gateway 3 is the perfect solution for vehicles with hybrid
CAN / J1850 network systems.
 The Gateway
3
provides messages translation across differing vehicle
networks, such as CAN or GMLAN to J1850 or GM Class2 and vice
versa. The Gateway 3 incorporates up to four CAN
channels and a J1850 VPW channel. A LIN channel can also
be added.
In addition
to message translation, the Gateway 3 can also transmit
messages based upon switch or sensor I/O and control I/O
(relay drivers, LEDs, etc.) based upon message receipt.
The Gateway 3 is configurable to
support High-Speed CAN (GMLAN), Single-Wire CAN (GMLAN),
Low-Speed Fault Tolerant CAN, J1850 VPW / GM Class2, and LIN
protocols.
DGE GW3 Development Platform
Module
DGE will develop customized Gateway 3 software to meet customer
requirements for specific applications. Software updates
can be loaded via
the GW3 RS-232 serial
port and HyperTerminal on a PC. View our Gateway 3
datasheet for more information.
CANduit
Transceiver System
DGE's CANduit is a CAN vehicle bus transceiver system
that provides convenient accessibility to the vehicle’s CAN-B and
CAN-C buses in the passenger compartment.
The CAN-B and CAN-C bus messages
are passively received by the underhood CANduit module and
sent through the firewall via the existing vehicle diagnostic
harness. The interior CANduit module recreates the CAN
messages, preserving message sequence. Standard data
loggers and bus monitor tools can be attached to this device
for various data monitoring and capture applications.
CAN-D diagnostic functionality is also preserved.
CANduit uses the existing
vehicle diagnostic harness without any modifications, and the
CAN-B and CAN-C buses are not extended which protects the bus
integrity. Installation is quick and avoids compromising
modifications to vehicle harnesses. View our CANduit
datasheet for more information.
Serial to J1850/CAN Protocol
DGE’s Serial to J1850/CAN (SJC) communications protocol, used in
conjunction with our Gateway, acts as an interface between a
host RS-232 port and CAN-B, CAN-C, and J1850 vehicle buses.
The
host computer, a PC or a PDA, sends and receives CAN and J1850
messages via the RS-232 link. Filters for CAN and J1850
messages are set up using RS-232 commands, with the filtering
taking place on the Gateway module.
The SJC protocol and Gateway module,
allow a user to
write high-level PDA or PC-based software for controlling or
monitoring various vehicle buses. Engineers can rapidly
perform CAN and J1850 bus analysis in order to identify and
resolve bus-related issues. The capability to monitor all
buses simultaneously with a common time-stamp is beneficial
for troubleshooting network-timing issues. View our SJC
datasheet for more information.
