Version 1.B 

 

Baseline Signal Suddenly Changes 

A change in the baseline signal is normal if the temperature, gain, or speed setting has 
been changed. If this occurs when none of these settings have been changed, there may 
be excessive humidity in the camera vacuum enclosure. Turn off the camera and contact 
Princeton Instruments Customer Support. See page 94 for contact information.  

Camera Stops Working 

Problems with the host computer system or software may have side effects that appear to 
be hardware problems. If you are sure the problem is in the camera system hardware, 
begin with these simple checks: 

 

Turn off all AC power. 

 

Verify that all cables are securely fastened. 

 

Turn the system on. 

 

If you hear 2 clicks separated by 1 second (shutter opening then closing), the 
shutter is working. Call Princeton Instruments Customer Support for further 
instructions. 

If the system still does not respond, contact Princeton Instruments Customer Support. 

Camera1 (or similar name) in Camera Name field 

 

Figure 56.  Camera1 in Camera Name Field 

When a PVCAM-based camera is detected/selected during the Camera Detection wizard 
(formerly the Hardware Setup wizard), a default name such as Camera1 will be shown in 
the Detected Hardware table and will be entered in the 

Camera Name 

field on the 

Setup|Hardware|Controller/CCD

 tab page and in the Hardware Setup title bar. 

Because this name is not particularly descriptive, you may want to change it. Such a 
change is made by editing the PVCAM.INI file that is generated by Camera Detection 
wizard (or by the RSConfig.exe if you have a software version 2.5.19.0 or earlier).  

To change the default Camera Name: 

1.

 

Using 

Notepad

 or a similar text editor, open 

PVCAM.INI

, which is located in 

the Windows directory (C:\WINNT, for example). You should see entries like 
the ones below. 

[Camera_1] 
Type=0 

Name=Camera1 

Driver=pmwdm2k.sys 
Port=0
