NetBridge Installation
NetBridge has ei ght serial po rts plus two Ethernet po rts. The first Ethernet port is conn ected to the C100’s network. The s econd por t is for co nnection to t he I nternet; this can be via DHCP server (for a dy namically assigned IP address), or a static IP address defined by the operator. The IP number (in ‘dot’ not ation) will be shown on the front panel while the unit is powered.
In facilities with a firewall to the Internet, this address is likely to be for internal use within the installation and not visible to the ou tside w orld. For extern al diag nostic access, the firewall will have to be s et to pass (and redirect) t he appropr iate inco ming traffic to t he NetBr idge unit , which will have to be ag reed with and configured by the facility’s IT staff.
NetBridge operation is more fully described in a separate document which is supplied with the hardware.
Connection
The eight serial ports are all located on the single
Serial port 8 may be connected to a data terminal (or software terminal emulator) for permanent local diagnostic access without requiring login. (see Appendix C for cable details)
Access
For security purposes, the NetBridge file transfer functions can o nly be ac cessed by one regis tered user who must be logged into the Central File Server (CFS). This uses the secure HTTPS protocol, which must be passed through any firewall (and redirected as required), although this is unlikely to cause any security concerns as it has 128bit Secure Socket Layer encryption. For file transfer between the console and the CFS, the u ser must be logged in at the console itself. For file transfer between the CFS and another computer (eg. authorised freelance engineer or SSL support staff), the user may login from an Internet connection, with the same username and password security requirements.

File Transfer
If a console operator wishes to export a session template to the CFS so that others may create offline setups from it, secure login from the C100 allows that file to be uploaded to the facility’s private account on the CFS, so that registered users can download the t emplate and upload t heir own setup s. Any existing setups in th at account can be downloaded from the CFS to the console’s hard disk.
Remote Diagnostics
In order to access a C100’s diagnostics through its NetBridge, first you need to know the IP address of that unit (on the front panel, or defined by a firewall/router), which can be determined by contacting the facility’s IT staff or consulting the security arrangements agreed with them. Once a secure connection has been made, running the terminal server application on the NetBridge will allow y ou to connect from the Internet to any of the seven ‘console diagnostic’ ports on that NetBridge.
