Chapter 5: Maintenance & Troubleshooting
The C-DiGit Blot Scanner requires a network based connection between the instrument and the
computer. The C-DiGit Blot Scanner uses IPv4 and IPv6 Link-
Local Addressing to automatically create an IP network without any user configuration or
additional servers. For this addressing to occur properly, the following settings must be configured:
1) Port 50000 must be open (Windows 7, 8, and 8.1).
Communication port 50000 is utilized as the default port for the UPnP (Universal Plug and
Play) protocol. This service is noted to hold this network port consistently open, listening for
devices that support the technology. This port simplifies intelligent device connection to net-
work environments. The network port 50000 makes it possible for devices physically connected
to a single machine to be shared with other clients under the same network.
2) Port 5353 needs to be left open. This is required for Bonjour, mDNSResponder to auto discover
instrument.
3) Firewall should not block any part of Image Studio or the Java software platform that is
installed with Image Studio.
4) Firewall should not block port 50000.
5) IPv6 must be enabled (Windows 7, 8, and 8.1).
USB Cabling Problems
If you are experiencing problems connecting to the C-DiGit Blot Scanner using the USB cable, note
the following:
The Image Studio installer for C-DiGit includes the required USB RNDIS driver.
l
Image Studio must be installed on Windows before the USB cable is connected between the
l
C-DiGit and the computer.
After the Image Studio installation is complete, connect the USB cable between the PC and the
l
instrument and power on the instrument. There should be a system notification that new hard-
ware is found. Depending upon the system, this notification may take place immediately when
the cable is plugged in or it may be a few minutes later.
During the Windows new hardware installation, the system may give the user a choice between
l
discovering drivers on the internet or from the local installation. If the computer is connected to
the internet, pick the selection that looks for drivers on the internet. If the computer is not on the
internet you may need to specify the location. If the drivers are not found automatically, choose
'Install from a list or specific location', and navigate to the <Program Files\Licor\Image Studio
Digits\driver> folder.
After installing the driver, start Image Studio and attempt to connect.
