USB to serial adapter issues??

I finally bought a USB to serial adapter to get the Profilux connected to my new serial port-less laptop.

I cannot get it to connect to the profilux. I can get a connection directly connectiing the serial cable to my old computer. Not sure if there is a setting I am missing? All drivers are installed, and Device Manager says its working correctly.:confused:

Also, If I am running Metal Halides, do I set the socket up as Timer or Illumination?

Also controlling CO2 Solenoid on CA reactor. Should this be set to Increase or Decrease pH? I'm thinking decrease to keep the reactor at a low pH, but I need to hash this out.

Lots to learn here!:eek2:
Thanks all,
Chris
 
is the COM-port-number (e.g. "COM3") OK? (check device manager and ProfiLux connection settings)

"do I set the socket up as Timer or Illumination" - as you like, if you set it as "illumination" you have more functions, e.g. "temp. dependent light reduction"

make something low = decrease
 
a lot of programs wrote for serial ports are usually using ether com1 or com2, and won't work if numbered higher.
I've have also seen software where the serial can't be changed to USB, and had to install a serial card(desktop)
 
Matthias,
It looks like the adapter is port Com 5, but the Profi is Com 1. How do I change the Profi to Com 5? Or do these need to match?
Thanks!

click in ProfiLuxControl the button with the 3 dots "..." next to the dropdown field with "RS232/USB" and change there the connection settings
 
There is only RS232 or TCP/IP. It is already set to RS232. I see no option to change Com port #s. ?

BTW this is V 4.0.0.3
 
"make something low = decrease" Umm thanks :D :lol:

What I am saying is I need to figure out the best programming to use both pH probes. One will be in the reactor, the other in the tank. So I need to control the pH in the reactor with the solenoid, say socket 1, but also need socket 1 to turn off if the main tank pH drops too low.

I'm sure its been done. I just need to get my head around the program:) I really appreciate the help!

No USB? sounds just like 1 of those programs, try changing the USB on the PC to com 1. (not in the program)
 
limonster, it seems you never used ProfiLuxControl??

Here you adjust your COM-port:

In this example I set it to 37
 
No I haven't but it looks like a great program and would really like to try it sometime. Where can i get a copy?

I've just come across many new machines that just don't have the RS232 serial ports or even the 25pin printer port anymore,(mine doesn't, Everything connects by USB and USB isn't listed by com ports.) so there isn't even a com port area in the device manager to have a com port in.

And I've also come across a lot of programs that want RS232 serial and won't work with USB. (like some timeclock programs and metal engraving programs)
On the Timeclock program, a generic USB to serial adaptor didn't work, we actually had to call the Timeclock software maker and get a special (propritary) USB cable from the software maker, then it worked thru the USB.
(H20ENG had stated that the USB to serial adaptor didn't work)

Now I haven't even seen what this program connects to, but going by the software pic you posted, there should be some way to connect by USB (Unless it's an older version of the software that was before USB, it is listed as Ver4.0.0.3 and I don't know where the versions are at)

I guess what I'm trying to say is that it might be the PC and not the software.
 
Hi sorry for the delay in responding. I did a COM scan and it reset to COM 5 to match and it works fine. Thanks again for your assistance! Now for more new threads with more questions!:)
 
At installation PL 2303 on the computer with system Vista the program writes that driver data do not approach.
Where to take the driver for port USB under Vista.
