Comment on iMax B6 charger protocol reverse engineered by Bjorn

There seems to only be logging available for the B6AC V2, so I started digging into how to start charge/discharge with the new HID interface.

Probably won’t finish deconding the whole protocol, but some of the findings are here at my fork of existing logging code https://github.com/beikeland/imax-b6mini-datalogger/

oh… and for what it’s worth i paired mine with an old 3com in the lab, and the 3com did what we wanted and took the vlans into account.

Hi Niobos,

Well it’s 2018, and i have the same grumble. Indeed the HP solution is dangerous as it designates a port that can’t actually carry the traffic for the vlans which the instance is configured for. In my opinion very stupid.

I think replacing the switches may be the way to go!

Hey, thanks for the quick response. Here is an example for the class-maps, see below. I’d like to fold them in a similar manner to how you folded the interfaces. I just made a copy of the interface code and changed the keywords to “class-maps”

class-map match-any DSCP_Trusted_Hosts
description Marking Class for Hosts with Trusted Markings
match access-group name DSCP_Trusted_Hosts

Sam,

Can you post more information about your error. Does it say on what line of what file the error occurred? What do you mean by “your interface line”?

I have a large number of router configs that have class maps. I tried to copy your interface line to fold the class-maps. I keep getting an E475 error “invalid argument” Any help would be greatly appreciated.

thank you

Sam

Trying just to access my SM3000S. I’m a server admin so I think I know a little about connecting networking kit but this thing just does not want to communicate, I have it connected to a powerline network system which I tested with a laptop and works fine, the LAN connecton light goes on when I turn on the ethernet on the SM3000S but the static IP I have set does not show on my router and I cant access it via the powertalk software. 🙁

To accept either between 3 and 4 characters, you need to change it to \w{3,4}

In reply to StevenMa questions about the script failing for the MT series converters. I have found the issue but I am not a coder and would appreciate if somebody can help me with the following.
Is seems the MT series does not know the UDC command but instead has the UD01 and UD02 commands.
However, this peace of code:

die(“invalid response”) unless $V_MSG =~ m/^\|64:(\w{3})=([0-9A-F]+)\|([0-9A-F]{4})}$/;
# TODO: check checksum
die(“wrong response”) unless $1 eq $P_COMMAND->{‘name’};

Checks the length of the returned values and expect a 3 letter code to identify the returned value. But, we are getting back a 4 letter identification code. I can change the w{3} to w{4} but than it fails for all the other queries.
Here is a query and response from the converter getting CUD02 from one of them (I have two):

Query: {FB;D6;27|64:UD02;UGD;UI1;UI2;UI3|08B4}
Response: {D6;FB;3C|64:UD02=1251;UGD=D28;UI1=F45;UI2=F45;UI3=F4E|0D86}

How can I change the piece of code to also accept both 3 and 4 letter commands?

Thanks in advance.
