Title: Advanced Serial Data Logger Question Post by: sshowers on July 23, 2009, 12:28:13 AM I am evaluating the ASDL product to try to capture data being sent to a serial dot-matrix printer (OKI ML390+) from a building access control (card reader) system. The system currently prints a line of text to the printer every time someone swipes their card to get into the building. My goal, eventually, is to insert this "line" of text into a SQL table.
I have installed a serial tap between the card reader and the printer from which I am able to capture data. I'm having an issue, however, with the data coming out of the stream. What shows up on the printer as: 0869 JUL 22 09 09:24:51 LASTNAME, FIRSTNAME ACCESS DV4 Card Reader Is being captured off the serial port (in ASDL) as: ÿú,jÿðÿú,jÿðÿú,jÿðÿú,jÿð€ÿú,jÿðÿú Is there something simple I've misconfigured? I'm sure this is a total "nube" question; but I would apprecate any guidance you can offer anyway... Title: Re: Advanced Serial Data Logger Question Post by: Arthur Grasin on July 23, 2009, 07:35:11 AM It seems that you selected a wrong baud rate. Also verify that you've connected TX line of your access control system to RX pin of the computer's serial port.

You were absolutely correct about it being the wrong baud rate. Once I verified the printer's setup and set the baud rate correctly I started receiving non-garbled data.
It seems that, once again, the internet (specifically DSL and the fact that I've not touced a modem in more than 12 years) has killed brain cells I used to rely on regularly. Or maybe it was the bourbon. Now, on to testing data inserts into SQL Server... Thanks again! --Scott |
