I just got a previously owned DU-640 spectrophotometer. For some reasons, it came with a CD disk with DU800 System and Applications Software (v 2.1).

My questions are:

1. Is it possible to connect DU-640 to old laptop through RS232?

2. If yes, would DU800 software work with DU-640?

3. If not, what floppy drive to use and how to connect it to transfer data from DU-640?

Thank you very much in advance

Yes, you can connect the DU640 to a PC via RS232 BUT you cannot use the DU800 program to do so. The DU800 software works in conjunction with the DU800's internal computer via a USB connection. The DU600 series can be connected to a PC using a Beckman program called DU WinConnect software. I doubt that you will be able to get it anymore from Beckman but you can try them or try to find it online. It is a very easy program to use and worked very well considering the limitations of both devices. I had several customers that used it and liked it Don

Don, thanks a lot for your prompt response. I appreciate it. If it is not possible to control DU-64- from laptop, I would better transfer the data as text files using a floppy disk, for example. Can I do it? If yes, how could I connect a floppy drive? Alex

The only way to transfer files via a floppy disk was by using the optional floppy disk drive that was connected internally to the main board and then thru a cable connected to the back panel of the spec. I know of no other way to do what you want to do. I may still have a copy of the WinConnect software on CD buried in my archives. If I do I will let you know here and we'll figure out how to get you a copy. Don

Don, I so much appreciate your encouraging support and help! If you can find a copy of the WinConnect software, that would be great. Alex

Don, I turned the machine off and it shows two failures:

1. RAM FAILURE and 2. RAM BATTERY BACKUP FAILURE. Is it fixable? Please advise. It is sad, I just got this machine today. Alex

Alex, It may take me a few days to deal with getting thru all of my old stuff so please give me some time on trying to find the disk.

"ON" not "OFF"

Yes it is easy to fix.  There is a lithium battery on the main board that can be replaced.  The fact that you received this message means that everything previously stored in the battery backed up memory will have been lost.  So basically you are going to be starting from ground zero other than the hard programs stored in the ePROMS.  So after starting the spec up after replacing the battery expect to see the same errors UNTIL you recalibrate the spec.  If you have what is known as an accessory board installed on your spec then you will have to remove it from the back of the spec in order to get to the battery.  The battery is a BR2325 lithium battery.  It is not one of the most common large button batteries out there but it is the only one that will fit properly.

Thanks a lot, Dan! But as I understand, this relates to "RAM BATTERY BACKUP FAILURE". But what about "RAM FAILED". Does this failure also relate to the battery?

Don,

thank you SO MUCH!!! It worked exactly as you said. Now I need to connect Pelier temperature controller. Which RS232 slot it connects to? If it goes to COM/RS232, does it mean that then I cannot connect the laptop?

Alex, Yes, you use the 25 pin RS232 connector on the spec typically go to a 9 pin RS232 on most Pc's or laptop. I'm trying to remember but you may need a crossover cable to make it communicate properly. I will try to contact an old coworker to see if he remembers. From your comment did you already come up with a copy of the WinConnect software? If so then great. I went thru a lot of "stuff" yesterday but did not find it yet. If you have it then I stop looking so please let me know. By the way, what part of the world are you in? I lime to keep track of where people are at that I have helped. Don

Don, I am from Worcester, MA. I do not have a copy of the WinConnect. I just want to be prepared. :) I understand that the 25 pin RS232 connector goes to the 9 pin RS232 on a laptop. My question is how then I can connect the Peltier Temperature Controller if there is only one COM/RS232 port?? Alex

OK. I misunderstood what you posted. The Peltier cell holder connects to the world FIRST thru the brown connector inside the cell holder compartment. Do you have the single cell Peltier holder or the multicell holder? You then connect the Peltier controller thru the connector on the back of the spec labelled for that as it does not use an RS232 connection to control the temperature of the cell holder. If you do not see a connector labelled for Peltier connection then your spec is missing the option to utilize that function. If your spec is properly configured you will control the temperature thru the spec itself on the main display screen. Some words of caution IF you have that capability, NEVER make any connections with the controller on as you will definitely blow the fuses inside of the controller which are a pain to replace. Hope this helps and I will get back to you after I look some more for the disk. Don

I have both: single cell Peltier holder and 6-cell Peltier holder. I have a Standard Transport system and an accessory board. I see that the brown connector inside the cell holder compartment is connected to the accessory board. However, on a back of the accessory board there is no connector labelled for Peltier connection (only: "Kinetics/RS232", "Batch", "Sipper", "Transport" and "Plotter/RS232"). Does it mean that the machine has no Peltier option? Can I fix this problem?

Alex, Connect the temperature controller to the "transport" connector (J8)on the accessory board and you should be good to go as to temperature controlled cell holders. I will try to find the disk over the weekend but at least you will have an operational spec. You have other possible issues especially as the lamps get old and you start getting errors. How many hours are there on your UV lamp right now? I'll help you out all that I can although it would be quicker using regular email but that is up to you.

Don, the "transport" connector has DB15 pins while the temperature controller says to use DB25 cable 517234 which is DB25 male to DB25 male cable. What cable I can use to connect DB25 temperature controller to DB15 "transport" socket on an accessory board? UV lamp has 950 hours right now. My regular email is IceAge07@yandex.ru. Don, I really appreciate your invaluable help and your priceless input. Alex

Please forgive me if I too am totally confused by this thread. There is a cable that comes out through the back of the unit from the cell holder, and THAT connects to the 15 pin transport connector, but what does the 25 pin cable from the temperature control unit connect to???? Does this mean there are TWO kinds of option board, BOTH of which have a transport connector, but where only one of the two also has a connector for the temperature controller?

There is only one option board. The temperature control unit connects to DB25 "KINETICS/RS232" port on an option board.
