Joe_ValleyMation Posted August 23, 2010 Report Share Posted August 23, 2010 Hi Everyone, I have a Jazz JZ10-11-R16 / MJ20-PRG which doesn't communicate Error Message: "Communications could not be established..." I've tried U90 ladder and also Unidownloader with the same results I've put it into BootStrap mode, with the same results I've used another MJ20-PRG and cable I've tested the same PC/USB adapter/Port with Visilogic and a V130, working fine. Version Used: JZ10-11-R16 V1.10 (B03) HW: A Bin Lib: FE BootStrap V1.10 (B00) U90 Ladder V6.1.7 (DB 109) Unidownloader V 4.1.01 I'll appreciate your suggestions. Thanks!

R.Mozes Posted August 23, 2010 Report Share Posted August 23, 2010 Hi Joe, Which D-Type adapter are you using? is it MJ10-22-CS10 or MJ10-22-CS25? You should use MJ10-22-CS10 with MJ20-PRG and 6 wire cable! BR, Reuven Link to comment Share on other sites More sharing options...
2rlp Posted August 23, 2010 Report Share Posted August 23, 2010 Hi Joe, Not all Serial to USB converters work with Jazz. You will need the Converter specified by Unitronics. With Vision PLCs and even with M90/91, any type of Serial to USB will suffice. Ron Link to comment Share on other sites More sharing options...
MVP 2014 Simon Posted August 24, 2010 MVP 2014 Report Share Posted August 24, 2010 Also, does the MJ20-PRG plug fully into the unit? Take the back off the PLC to check. We have seen the occasional case where the alignment of the connectors is slightly off and the MJ20-PRG doesn't plug fully in. Alternatively, with some misalginment the pins on the PLC connector can get pushed back and bent, then they do not plug into the adaptor even if it is pushed all the way into the housing.

Ron It's true, not all usb-serial work with Jazz but they work with others Unitronics OPLCs. I have some customers had to buy the recomended Unitronics' converter.

Joe_ValleyMation Posted August 31, 2010 Author Report Share Posted August 31, 2010 Thank you all. The problem was the physical connection of MJ20-PRG. The plastic cover does not allow the MJ20-PRG to plug in fully into the unit. I had to remove the plastic cover and plug very carefully into the Jazz. Feedback for Unitronics, some MJ20s does fit correctly into the Jazz. Thanks! Joe Link to comment Share on other sites More sharing options...
Luciak Posted July 19, 2011 Report Share Posted July 19, 2011 Hi. I have the same problem as Joe. The only differene is that I do not use USB adapter, I have COM port on my laptop. I can connect with V130 but not with Jazz. I use MJ20-PRG with 6 wire cable and MJ10-22-CS10 plug (also checked on MJ10-220CS10 - not working either). Laptop is working on power adapter (not on battery). I have tried dismounting PRG adapter, changing cable and changing plug - all seems to be ok. Moreover, the same set works on my friends computer. I have also tried to reinstall U90 Ladder and deinstalling COM port and installing it again -> still nothing. Any ideas what can be the problem? Because I am out for now and am not looking forward to the idea of reinstalling whole Windows. Regards, Luciak. Link to comment Share on other sites More sharing options...
Stein Yair Posted July 19, 2011 Report Share Posted July 19, 2011 Hi, First of all, let's check the basics. Make sure no other software is using the port, e.g. VisiLogic. Make sure the communication settings in U90 Ladder are the same as in VisiLogic exept the buad rate which should be 9600. Link to comment Share on other sites More sharing options...
Luciak Posted July 20, 2011 Report Share Posted July 20, 2011 Oh - I forgot to add that but it was one of the first things I've checked -> I mean if the port is not blocked and communication settings are correct. Link to comment Share on other sites More sharing options...
Stein Yair Posted July 20, 2011 Report Share Posted July 20, 2011 What version of Windows you are using? If you are using Windows Vista or 7, disable the UAC. See instructions here: http://www.unitronics.com/data/uploads/VisiLogic_Software_New/Disable%20UAC%20Vista%20+%20WIN7.pdf In U90 Ladder, go to Contoller > M90 OPLC Settings, click on Advanced, set the Parity to Even, the Stop Bits to 1, and the Data Bits to 7. check the box of Force PLC settings to Link to comment Share on other sites More sharing options...
Luciak Posted July 20, 2011 Report Share Posted July 20, 2011 System: Windows XP Settings: Tried everything - really. Forcing PLC, setting default values to U90 and PLC, changing U90 and PLC to other setting (eg.: 8/N/1, 9600, 19200, etc.) And nothing - I think I will reinstall WIndows today and let You know if it helped...
