Author Topic: SDDS DFP-D2000 QC-Software problem Hannes Ziegenhorn Film Handler Posts: 10 From: Großbreitenbach, Thüringen, Germany Registered: Jan 2017 posted 11-05-2019 08:01 AM                     Hello Since I startet playing around with SDDS processors, I often had trouble connecting the Sony DFP-D2000 to a PC. The Setup-Software works with almost all Computers I tried (Windows 98 or XP). But the SDDS QC-Software (V3.0 from the warehouse) only worked on two W98-Laptops so far. On the Windows 98 SE Computer I set up last week, the Setup-Software runs fine, but the QC-Software shows the Message: "Not able to establish communications with DFP number 10803. Try reconnecting a different serial number." The serial number is as shown on the DFP display. Also with another DFP-D2000 (and its respective serial number) I get the same error message. So it seems to start a communication with the processor and getting a response, but something isn´t working as supposed. Could please somebody explain to me what the cause of his error is and how to fix it. Thanks Hannes  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 11-05-2019 09:42 AM                     Are you using a DB9 null cable?  |  IP: Logged Michael Zarits Film Handler Posts: 11 From: Eisenstadt, BGLD, Austria Registered: Jan 2019 posted 11-06-2019 12:34 PM                    If you already use a DB9/null cable as Brad mentions try different brands. I used 4 different null cables until one finally worked. Unfortunately there's no manufacturer branding on my working cable.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 11-06-2019 12:39 PM                        There is a standard pinout for a null modem cable, so that shouldn't make a difference if the cable conforms to the standard. My guess: is the OP using a USB-to-serial adapter or a computer with an actual serial port? The former sometimes causes problems with certain types of equipment. Tripp-Lite/Keyspan is generally recognized as good, but, of course, a physical serial device is preferred. Maybe someone who regularly deals with Sony equipment can post what works.  |  IP: Logged Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 11-06-2019 01:04 PM                     Adapters camn be strange........make you're own null odem cable, or use small null model db9 changer...... Last time i did play with SDDS was few weeks ago, and i did set up virtual machine with XP so i can run it under windows 10 on lamptop, than i did not have problem to use either com port which is genue on my elitebook, ether some profilic usb-rs232 converter........but is you use converter it MUST be rs232, not just regulat com which run just pure RX/TX, but it needs to have real RS232 voltage levels, because sony has MAX232 on UART and level which are out of standards are not recodnized.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I make my own using 9-conductor shield with the right gender connectors...never had an issue.  |  IP: Logged Hannes Ziegenhorn Film Handler Posts: 10 From: Großbreitenbach, Thüringen, Germany Registered: Jan 2017 posted 11-07-2019 04:35 PM                     I built a male to female full-nullmodem-cable according to the diagramm in the DFP-D2000 software manual. I heard that some USB-adapters don´t work, so i´m using the serial port on the mainboard (the correct drivers are installed). But my initial question remains: Why does the Setup-Software work correctly but the QC-software won´t connect and gives the error message. So they should be able to communicate and I guess it could be a software-issue. Are there any earlier versions of the QC-software available?  |  IP: Logged
