Victor 86B Issue

Postby Delghisallo » Mon Apr 11, 2016 12:33 pm


I've just joined Too Much Coffee, so firstly hello!!

I have recently bought a Victor 86B to use in conjunction with my coretto and RoastLogger. All the instruction manuals are in Chinese so not sure if I'm doing something wrong, but when I connect the meter via USB to my laptop, the laptop recognises that a new device has been plugged in and on first plugging in it looked like a new driver was installed.

However when I try and connect through Roastlogger I am not getting any data transmitted (I have tried pressing the RS232 button). I also tried to connect and transmit data through the Victor software, but get an "open device failed" error.

I also tried the above on a second laptop and had the same issue.

I have tried to contact Victor but my email must be on the slow boast back to China, as I have not received a reply!

As anyone on the forum any ideas or experienced similar?

thanks in advance

I still haven't bought a Victor yet so I can't help you, but perhaps GreenBean will show up and share some thoughts with you about the problem. Good luck and let us know how you get on.

I decided I needed a bit of a change so I roasted some Monsooned Malabar. That was a change!

Hi Gareth, welcome to TMC :D I am sorry to hear about your problem with the Victor 86B multimeter. RoastLogger does not require any driver installed to communicate with the Victor 86B. Over the years a few users have been supplied with faulty meters. The fact that yours is not communicating with RoastLogger or the manufactures own software confirms that it is faulty. I suggest you contact the supplier rather than the manufacturer and request a replacement.

Hello All,

I'm also new here. Recently started home roasting using Behmor 1600 Plus.

I recently purchased Victor 86B, but I also cannot to get it to work with RoastLogger. When I connected the multimeter via USB, it is displayed in Device Manager under category "Ports (COM & LPT)" and the name is "Silicon Labs CP210x USB to UART Bridge (COM3)". Is this normal?

Hi all,

I purchased a Victor 86B and would like to start my home roasting with RoastLogger. However, yet to successfully connect the Victor 86B with RoastLogger. Here is the details:

1. Windows 10 (x64)
2. Java SE Runtime Environment 8u211
3. RoastLogger version 2.4.0 stored under folder "My Document" as recommended.
=> RoastLogger is launched successfully.

Connecting Victor 86B:
Case 1: USB plug in PC without any driver installation
=> Vicotr 86B is not success to connect to RoastLogger by clicked "USB HID DMM's" and the following message is keep in waiting

Attempting connection to: C:\Users\Lewis Li\Documents\RoastLogger-ver-2.4.0\HID\USBHIDReader_Win.exe
Windows version 1.6 of USB HID Reader for use with Roast Logger
Copyright T R Coxon (GreenBean TMC) 2009-2011
This program reads data from up to 2 of the following in any mix:
Tenma 72-7712 or Uni-T UT322, Victor 86B or 86C.
Please connect the device and start communication .....

Case 2: USB plug in PC. Victor 86B Driver is installed.
=> Victor 86B is well connected to Victor program (DMMDataCollector), waveform of temperature is shown with reasonable values.
=> Victor 86B is not success to connect to RoastLogger by clicked "USB HID DMM's" and the same message above is keep in waiting
=> In Trial & Error, by clicked "Serial DMM's" and set center309 with (9200 N81), data is received...but value is not reasonable. (e.g. 67855 degree....)

No luck as well, when I try to connect Victor 86B to a Mac book by USB under "USB HID DMM's"

Any recommendation about solving this issue? Please help....
