Hardware Revision Descriptions

Revision A
General release: 12 September 2000
Original release.

Revision B
General release: 6 February 2001
Replaced U31; was a 78L08A; changed it to a 78L15A device. This was done to increase the supply voltage to the SWC transceiver. With the 'L08' device the SWC wakeup voltage was at or below specification.

Revision B2
General release: 2 April 2001
Removed R78 (1 Kohm). Installed R79 (31.6 Kohm). This changed the slew rate of the VPW signal to the correct value.

Revision C
General release: 10 April 2001
Updated PC board design. Corrected the J8150 VPW slew rate control resistors. Changed the SWC transceiver to a Philips AU5790D8 device.

Revision D
Limited release: 26 April 2001
Separated K-line power source from rest of unit power. Consult the document: Description of Hardware Revision "D" for detailed information. Document available from our Download page.

Revision E
General release: 27 November 2001
Added support for CAN-B (ISO 11519) operations.
Modifications to the main board to include:
Remove the following resistors: R15, R16, R17, R18, R19, and R20.
Cut the track from P2-9 on the bottom of the board.
Add the following wires:
P2-5 to via next to R110; to U17-20.
P2-6 to via between R35/R36 and U34; to U17-16.
P2-9 to K7-1.
P2-10 to K8-1.
Install P2.
Install the add-on board, AVT-718W.

Revision F
General release: 14 February 2002
Corrected and changed a few nodes/nets to more easily accomodate the CAN-B add-on board. With this revision the AVT-718 board will not require any modifications to install and use the CAN-B add-on board (AVT-718W).

Revision G
General release: 19 September 2002
Added CAN-B support to the board (eliminating the AVT-718 "W" add-on board).
Added RS-422 support for serial communications to the host computer (eliminating the AVT-718 "T" converter). Note that RS-232 or RS-422 are mutually exclusive on the AVT-718 "G" board. Either one or the other is installed. This is not a modification that can readily be done in the field.
Added jumper support to permit separating the K-line supply from the AVT-718 power source.
Changed the DC/DC converter to a smaller unit.
Replaced the large isolation diodes on the K and L lines.

Revision H

Revision J
General release: 15 July 2003
Modification to enhance LIN mode operations. This modification is required to use firmware version 4.4 and above, in LIN mode.
Connect a small wire (30 awg) from P2 pin #5 to U21 pin #5.
U21 pin #5 connects to a small via right next to the pin. Use a small X-Acto type knife (or similar) to 'carefully' clean out the via
connected to U21 pin #5. Solder a small wire (30 awg) into the via for U21 pin #5 and then connect that wire to P2 pin #5.
