1. Connecting the CAT-DEV

1. Connecting your CAT-DEV to the PC

There are three ways to connect your devkit to your PC: an unmanged switch, a second network card, or connecting to it directly. Using an unmanaged switch is the recommended method. Refer to the following chart for the advantages and disadvantages for each before deciding.

 

Connection Method Advantages Disadvantages
Unmanaged Switch
  • Isolates the connection between the PC and the CAT-DEV from most network policies (such as disabled DHCP, forbidden broadcast traffic, or restricted unicast traffic).
  • Isolates the connection from most other traffic on the network.
  • The CAT-DEV is accessible from other PCs on the same network.
  • Because the CAT-DEV is accessible from other PCs, other hosts may access the CAT-DEV.
  • Communication bandwidth may be impacted by other network traffic (such as web browsing or email) from the host PC.
  • Requires a reserved DHCP or static IP Address
Secondary Network Card
  • Isolates the connection from LAN policies (such as disabled DHCP, forbidden broadcast traffic, or restricted unicast traffic).
  • Isolates the connection from other network traffic.
  • Because the connection to the CAT-DEV is direct, communication bandwidth is maximized.
  • Requires a second network card be installed in your PC.
  • CAT-DEV is not easily accessible by other PCs.
  • You must ensure that the IP address of the secondary network card does not conflict with an existing IP address on the network.
  • Setup and configuration can be convoluted.
Direct Connection
  • Isolates the connection from other network policies and traffic.
  • Does not require a reserved DHCP or static IP address.
  • Because the connection to the CAT-DEV is direct, communication bandwidth is maximized.
  • Safest for critical operations, such as updating the firmware images of the CAT-DEV.
  • The host PC is isolated from the network and/or internet.
  • Other PCs cannot access the CAT-DEV.
  • Setup and configuration can be convoluted.
