Dear brothers
I want to communicate with Tatsuno XE, so i need Tatsuno protocol, too.
Can u help me? please send to email: [email protected]
Thank u so much.

 

Hi. Anyone wants to join a group to buy the Protocol documentation together? I found one to sell but think we could save the cost if purchase together.

 

hello guys please i need tatsuno protocol and bluesky anyone that can help me please?

I am currently working on the same thing. I am looking for the tatsuno protocol. Can you please help me with it

 

Hi,
can anyone help,I need tatsuno protocol documentation please

i am having protocol but i am unable to understand the crc calculation and addition of upper bytes and lower bytes. can you help me to calculate this.

thanks

hi Azhar,
could you please share with me the protocol please

need tatsuno protocol, please email to [email protected].

please share with me too [email protected]

 

...in case anyone is interested, I found a really old version from '97 here:

https://pdfcoffee.com/pos-protocol-pdf-free.html

...maybe someone here has a newer version?

Hi Brenzosa
If you have found the latest version, can you share it, please?
I believe the successors to version 97 are the 2002 and 2003 releases, the file codes are BSB000089 and BSB000090, and I haven't found them yet.

 

I try to connect Tatsuno Dispensing Pump to computer. Connection via RS485. But I don't know the protocol. I try to send 4 byte ($04 $40 $51 $05) from my computer and the pump send respond $04. The response from the pump just 1 byte. I need to know totalizer display and current liter displayed on the machine. Any one have that protocol??
COM Setting: 19200bps, parity EVEN, data bit 8, stop bit 1.

Please do let me now you can calculate the crc from pump data. Power On handshake

 

I trying to connect the dispenser with POWER ON protocol, it look like CRC-16 for the X^16+X^12+X^5+1 calculation, I try CRC with 00+XXXX to XXXX from the received message from dispenser, also make addition of upper byte and lower byte. Anyone done the part that able to help?

I did this successfully 5~6 years ago when I had a similar job.
I've forgotten the exact formula, but I do remember calculating it with Kermit crc16, then following a few steps until you convert the hex to ASCII. For example, if the result is A0 in hex, convert it to 'A' and '0' in ASCII.
If I have a chance to plug in my old hard drive, I'll try to share the communication reading log.

Thanks for reply, I try with Ker,it CRC16, but no luck. I did convert the hex result to ASCII, like A = 41, 1=31

hi, if you done this, could you please guide me?

Yes, It is using Kermit crc16, Thank to Acuy for the tip. the calculation base from 6 digits from the source 00XXXX, use Kermit to get the result which is 2 Byte. XX, If they are 3 byte in the result, truncate the highest byte. (most likely a 1), after that, form the code send back to dispenser is 00 + XX + ASCII 31 20 20 20 (this 4 Bytes is not in the book, it is "1" + 3 Space Characters ), 00 is the command.

Example:
04405105 024051 3030 32463432 0360 1031 04 -> 3030 32463432
04404105 1030 024041 3030 4545 31202020 0313 1031 04 -> 3030 4545 31202020
04405105 024051 36303130 0315 1031 04 -> 36 30 31 30 =POWER ON = ASCII 60 10

Hi, thanks for reply.

This is my data which I got from pump. Kindly describe in details how I convert it into 2 bytes.
Thanks

Hi,
I'd need the tatsuno protocol specs, too.
My email is [email protected]

Thanks and Best Regards

you still have the tatsuno protocol?

Hello myckchin & Naveed Rasheed
I'm having trouble sending a valid command to the Tatsuno pump — every time I try, I receive a 0x15 (NAK) response.

I’ve followed the protocol as described in the manual and I'm successfully receiving data like the following:02 41 51 30 30 37 43 30 32 03 65 I understand that this message includes the data field 30 30 37 43 30 32, which decodes to "007C02" in ASCII. So, reception seems to work .
However, I cannot send any commands, and for now I’m just trying to read the totalizer. Based on my understanding from the documentation, the request should involve a data field with the value 20 (hex).
I’ve attached the relevant documentation I'm working from. Could anyone please confirm what a valid "read totalizer" request packet should look like (with correct CRC/BCC and formatting)?

This is the sequence when the Console request the totalizer. The Pump address is 40.

So, can you show us your communication logs, so we can figure out what went wrong?

Thank you very much , meanwhile I have a connection an I could achieve all the function in the manual ...Thank you very much and for @myckchin too ..his example was good too .
