Bematech Virtual Serial Port and ACBrECF.DataHoraSB

smaniand · 7 Outubro, 2015

Buongiorno a tutti!

I have a Bematech MP 4000 TH FI. I use ECFTeste.exe to test the commands. When I connect the printer with onboard COM, everything is fine. When I connect with USB, using the Bematech Virtual Serial Port Driver rel 3.0.0.3, the command ACBrECF1.DataHoraSB times-out. I already increased the timeout values but without success. Already tried to decrease/disable the COM buffer, no way.

I tried to install 3.0.0.7 but with this driver the printer is not working AT ALL.

Here the logfiles when connected with USB and BVSP Driver:

The problem is very similar to another Issue occurring in Bematech MP4200

Did you tried the new Bematech Drivers ?

Ryan molina · 7 Outubro, 2015

Sei que o protocolo de comunicação é diferente, mas estou com o mesmo problema com MP 4200, que tem somente a opção de COM Virtual. Acontece aleatoriamente, tanto nos clientes como aqui no nosso ECF.

Estamos com o ACBr e os drivers atualizados.

Segue anexo o log.

Notei que no programa da bematech (WinITFI2 RAT) existem parâmetros, conforme imagem, para setar os tempos de espera de retorno. Todos os testes que fiz até hoje via programa da Bematech deram certo, normalmente quando passamos para as revendas de ECF que está dando problema no comunicação eles usam apenas os programas do fabricante para testar.

No ACBr sei que tem parâmetro pra Timeout e Intervalo, tem relação com esses da imagem?

====================================

I have the same problem with MP 4200 printer. These model has only virtual COM option for communication.

We have ACBr and drivers updated.

Log files are attached here.

I've noticed that using bematechs software (WinITFI2 RAT) there are parameters to set the timeouts for printer return. All tests that i've made until now using the Bematech software were OK. Usually when we tell hardware resellers that we're having communication issues they test only with the manufacturer software.

I know that ACBr has parameters for Timeout and "Intervalo", do these parameters have any relation with those on the image?

MP4200 usa um protocolo totalmente diferente

e no tópico anterior há um Link sobre essa situação de Loop infinito

Daniel,

I downloaded bemaghost and bemadrivers.

Executed with administrator privileges BemaGhost, option 99. Rebooted. Execeuted BemaDrivers --> MP 4000 recognized. Rebooted. Installed Bematech Virtual Serial Port X64 3.0.0.7, configured comport 5 --> FISCAL --> Radiobutton USB 0_MP-400 TH FI. Executed my software : no way. The printer does not print AT ALL, no commands are working. With 3.0.0.3 everything works (I think so), the only thing not working is the DataHoraSB.

Can be a Bematech issue?

Thanks!

Andrea

Here some screenshots....

@Ryan molina I my case I have a MP 4000 TH FI, anyway I tried to change the values on the ACBrECF component for timeout and interval between commands (I set 1 hour timeout...) but nothing changed, always the same problem. and ONLY with ACBrECF1.DataHoraSB

Thanks

Daniel Simoes · 8 Outubro, 2015

Looks like some problem on these new Drivers for MP4000... Can you please send the Log file created with the attempt using the new drivers ?

On MP4200 there is a similar problem... The workaround solution we created for MP4200, consist in transmit the command again, after TimeOut occurs...

Not sure if is possible to try the same approach in MP4000.... I need to investigate your Log files...

Can you provide more Log files, with the same error situation ?

smaniand · 8 Outubro, 2015

Hello Daniel

Here the logfiles with the new driver installed 3.0.0.7. I used the ECFTeste demo that is included with ACBr source code. I just pressed the button "Ativar", and I get the error : Impressora Bematech não responde (ACK = 0)

As I told you, with Bematech Virtual Serial Port 3.0.0.3 I can Activate the printer, I can do everything, only problem on ACBrECF.DataHoraSB.

With 3.0.0.7, I cannot even activate the communication.

Thanks

Andrea

Daniel Simoes · 8 Outubro, 2015

Do you use ACBr Trunk2 directory ? Probably this issue is already fixed on Trunk2

I notice ACBrECF is running a special code to read DataHoraSB, on escBematech... Since these model don´t have a specific command to return this information... ACBrECFBematech is querying a report "Leitura Memoria Fiscal", by serial, in order to capture DataHoraSB information on the texts of these report...

Looks like the problem is on the way ACBrECF is detecting the ending of Serial Reports (they always ends with [ETX])... buts as we can see, ETX is on the Log...

Recently, I fix a very similar issue, concerning problems on detecting ending of Serial reports... but only on Trunk2...

Please try the compiled version of ECFTeste, using Trunk2

Hi Daniel,

I am using trunk directory. I downloaded the ECFTeste compiled with trunk2, and DataHoraSB WORKS!

So, is there a chance to port the fix done on trunk2 also on trunk? Or the only way is to migrate to trunk2?

Many thanks!

Andrea

Si, I investigated a bit more. The problem is that I cannot debug, as I run delphi on a Virtual Machine, and the USB bema driver cannot be virtualized.

But...by adding some logs, I noticed that the problem is on ACBrECFBematech.pas, procedure VerificaFimLeitura, instruction:

result:= not fpDevice.Serial.CanReadEx(1000).

This command is used to be sure that, when ETX is received, no other informations are received on the serial. It is a sort of doublecheck.

So: when i connect the MP4000 with COM, everything is ok, no more data after ETX.

When I connect with USB and virtual serial port, the result of fpDevice.Serial.CanReadEx(1000) is always TRUE, even if ETX is received.

So it looks like that, via USB, there are some other "dirty" data on the serial still there, after the ETX.

I commented out this "check" and now all is working good, but I dont think that it could be a solution.

Thanks

And please have a look to this thread:

http://www.projetoacbr.com.br/forum/topic/19179-bematech-mp-4000-th-fi-erro-de-comunicação-e-fechamento-de-relatório-gerencial/

We have the same issue here, at the bottom of the thread you talk about DataHoraSB and CanReadEx

Thanks!

Andrea

Solution proposal, in ACBrECFClass.DoLeResposta

Fim := True ;
if not FimLeitura then
begin
Fim := False ;
try
fpRespostaComando := fpRespostaComando + { Le conteudo da porta }
fpDevice.LeString(100) ;
LenResp := Length( fpRespostaComando ) ;
except
sleep(10) ;
end ;

if LenResp <> fsBytesRec then
begin
// ECF está respondendo, portanto está trabalhando //
TempoLimite := IncSecond(now, TimeOut);
fsBytesRec := LenResp ;
end
else
FimLeitura := VerificaFimLeitura(fpRespostaComando, TempoLimite) ;
end
else
if AguardaImpressao then
begin
Fim := VerificaFimImpressao( TempoLimite ) ;
if not Fim then
sleep(200) ;
end ;

Here we check the FimLeitura only when there are no more data to read. When there are no more data, fpDevice.LeString will raise an exception, catched. Then LenResp will be equal to fsBytesRec, and we can finally check the FimLeitura.

With this solution we solve also the problem mentioned on my above post, regarding the ETX that is not a real ETX, and we can remove the fpDevice.Serial.CanReadEx(1000) in ACBrECFBematech.pas that is generating the problem.

Please let me have your opinion,

thanks

I applied the same fix from Trunk2 to Trunk... please update and test...

But I really encourage you to change to "Trunk2"...

smaniand · 12 Outubro, 2015

Ok Daniel, many thanks!

I will have a look on trunk2 migration soon,

Ciao

Andrea
