Installing SiLabs VCP Drivers for QSI Programmer for the JMRI

Installing SiLabs VCP Drivers for QSI Programmer
for the JMRI Decoder Pro Version 2.2 using Windows
http://maxrob.home.comcast.net
The SiLabs Virtual Com Port Drivers (VCP) can be used with the QSI Programmer so that the JMRI
Decoder Pro will recognize the Com Port the Programmer is on. To accomplish this, the best method
is to remove the SiLabs USBXpress Drivers required by the QSI Solutions Programs and REPLACE
them with the SiLabs VCP Drivers entirely! Warning! Make sure you have the latest versions of
Q1A and Q2 Upgrade Programs and the Quantum CV Manager Programs so you can use these with
the VCP Drivers. These Programs will NOW work with both the SiLabs USBXpress USB drivers and
the SiLabs VCP drivers This means that you can replace the USB Drivers and now using one set of
drivers for BOTH QSI Program AND JMRI Programs. Use following steps to uninstall USBXpress
Drivers, Reconfigure the VCP Drivers Setup File, Install and Configure the VCP Drivers and Setup
JMRI Decoder Pro and the QSI Programs for use with the QSI Programmer.
1.)
Remove USBXpress Drivers for QSI Programmer.
Using the Add / Remove Programs from Control Panel, remove any SiLabs USB drivers or USBXpress Drivers
installed for the QSI Programmer. If no drivers are present in the Control Panel, but the QSI Programmer is still
working, then Uninstall QSI Programmer from Device Manager. To Open the Device Manager, right click on My
Computer, choose Properties. Choose the Hardware Tab. Then Click the Device Manager Button. (Also available
from the Control Panel, System Icon.)
With the QSI Programmer powered and connected with the USB cable, right click and choose uninstall. Then
unplug the QSI Programmer USB cable.

2.)
Download and Unzip CP210x_VCP_Win2K_XP_S2K3.zip from http://www.silabs.com
From the CP210x_VCP_Win2K_XP_S2K3 folder run CP210x_VCP_Win2K_XP_S2K3.exe
using the default settings. Open the SiLabs folder created by the install. Expand the MCU
folder, and then expand the CP210X folder. Click on the folder named
Windows_2K_XP_S2K3_Vista.
In this folder is a file named slabvcp.inf.
Figure 6 – Location of slabvcp.inf
Open this file with notepad. This can be done by right clicking on the file and choosing Open.
Using edit / find from the menu, you can type in the Find What box: PID
You will find 5 entries with the following: PID_EA60
Change EA60 to 8208 on all five entries. All 5 instances should now look like this: PID_8208
Be careful not to change or remove any other entries that PID is part of.
Click file, save on the open notepad. Close notepad.
This change will allow the VCP drivers to see the SiLabs Chip inside of the Programmer.
(A copy of this file can be downloaded from the location you got these instructions from. If
you use this file, replace the original slabvcp.inf with this version)

3.) Execute CP210xVCPInstaller.exe from the same folder that slabvcp.inf is in. Use the default settings
and click install from the CP210X USB to UART Bridge Driver install Window. Choose “Continue
Anyway” button, IF you get the Windows Driver Warning "...has not passed the Hardware Compatibility
Logo Testing".

4.) The Virtual Com Port will NOT show up in the device manager until you plug in the QSI
Programmer and configure it to use the SiLabs VCP Drivers.

With the Power Cable connected and powering the QSI Programmer, plug it in to the USB port of your
computer.
The "Found New Hardware Window" should open, if you have successfully removed all of the USBXpress
Drivers.
Choose "NO" to search Update Site for Drivers. Then Click Next.
Figure 11 – New Hardware Found
Choose the default "Install Software Automatically"(recommended) setting and click Next.
Choose Continue Anyway Button if you get the Windows Driver Warning "...has not passed
the Hardware Compatibility Logo Testing". Drivers will finish installing. Choose Finish when
drivers are installed. You might get an information "balloon" from the notification area, by the
clock that the Hardware is installed and ready to use.

5.) Open Device Manager and confirm that the SiLabs Virtual Com Port is installed in the
ports section. The driver will assume the first available Com Port. (Normally 2 or 3) (On
this test machine it found Port 8 as the first Available.) What Ever port is found should
show up in the Preferences Window of the JMRI Decoder Pro.

(You can change the port by using the Advanced Button on the Ports Tab available from the
properties window of the VCP. Make sure not to choose a Com Port already in use.)
