Notes
General Description
Low cost multiple interface supporting: 2-wire CAN; Single Wire CAN;
J1850 VPW; and K-line networks.
Communication to host computer: RS-232 serial.
Hardware Configuration
Hardware configuration of the board is determined by customer requirements.
The hardware configuration is noted in the white "Rev" block on the
top of the board.
Some hardware configurations are listed below. Other configurations
are available, ask us.
A unique revision level and order number will be assigned for each
unique hardware configuration requested.
Internal Shunt Configuration
Updated: 19 August 2010
At time of shipment, all shunts for installed protocol support will
be installed.
PC Board Revision
The revision of the PC board is noted in copper on the bottom of the
board.
It only changes when the board is redesigned.
Revision Notes (prior to 19 August
2010)
Revision A0
Limited release: 21 February 2006
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
This board does not have JP2 jumper for the K-line signal.
Pull down resistors (24.9 K ohm) were hand installed for the ADC inputs
across the TVS diodes.
This board has an incorrect crystal configuration that was corrected
by hand modification.
Prototype.
Quantity built: 4.
Revision A1
Limited release: 5 April 2006
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
Corrected the crystal circuit and other minor changes to board layout.
Prototype.
Quantity built: none.
Revision A2
Limited release: 18 May 2006
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
Added jumper JP2 for the K-line signal.
Pull down resistors (24.9 K ohm) were hand installed for the ADC inputs
across the TVS diodes.
Initial production layout.
Quantity built: 8.
Revision A3
Production release: June 2006
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
Changed the layout to add pull down resistors (24.9 K ohm) to the
ADC inputs.
Production layout.
Quantity built (to date): 250.
Revision A4
Production release: 26 September 2006
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
Changed 2-wire CAN termination to Ford configuration.
Performed on request only.
Revision A5
Limited release: 9 February 2007
(Decommissioned ~17 April 2007)
Low cost multiple interface supporting: CAN-C; SWC; J1850 VPW; and
K-line networks.
Communication to host computer: RS-232 serial.
Modified a production AVT-841 as a prototype AVT-843.
Quantity built/modified: 1
Revision A6
General release: ~17 April 2007
Connect U1 pin #64 (PortA7) to U7 pin #2 (SCI1 TXD, PortS3).
This modification is only needed for KWP init functions and LIN mode.
Revision A7
General release: 14 June 2007
For revision "A" boards.
Modify the 2-wire CAN termination scheme to be Ford compliant.
Remove: R16, R17, R18. C25 can be removed or left in-place.
Install: R14, R15 (100 ohm); C20, C21 (470 pF); C22, C23 (100 pF).
Revision A8
General release: 17 July 2007
Remove R24; passive pull-up on K-line. This makes the passive pull-up
on the K-line compatible for LIN operations.
Revision B1
General release: ~ March 2009
Incorporated corrections from revision "A" board (flip operational
LED, wire for K-line control). Added mounting holes in the four corners.
Revision C
General release: 24 July 2009
Change the 2-wire CAN termination to the "Ford" configuration.
Remove: R18 and R16.
Install: R14 and R15 - 100 ohm.
Install: C20 and C21 - 470 pF.
Install: C22 and C23 - 100 pF.
Revision S
General release: 23 June 2009
Available for installation on any board, only upon specific customer
request. Most useful for customers that need to support CAN bus baud rate
of 1 Mbaud.
Remove 4 MHz external resonator (Y1) and replace it with an 8 MHz
resonator (AWSCR-8.00MGD-T).
Install a wire from U1 pin #109 (PortK bit 7) to ground (nearest is
C3 terminal furthest away from U1).
Revision T
General release: ~August 2008
Modification to change CAN4 channel from Single Wire CAN (SWC) to
dual wire CAN.
Remove SWC transceiver U6.
Install AVT-84x "T" board on top of U4 using both pins of JP3 for
mounting.
Install wires from the AVT-84x "T" board to the respective locations
on the main AVT-84x board.
