and clients employ a user name and password scheme for authorization purposes. The HDR 24/96 FTP implementation sets the client account to anonymous status, thereby allowing any fully functional FTP client to connect to the internal file system of the recorder. Because it’s possible that an unknown computer may connect to the mixer and/or add and delete files, care should be taken when connecting the mixer to a publicly available network (WAN).

IP Address

Without detailing the intricacies of network security and firewalls, you should be aware that configuring the HDR 24/96 with a publicly available IP address on a publicly available network may make the recorder’s hard drive and functions visible to network traffic, i.e., the Internet. When connecting two Ethernet devices directly, without including an outside network, this is a non-issue. Certain IP address ranges have been set aside by key Internet standards bodies for use in private networking applications. Those ranges are as follows:

Class A 10.0.0.0—10.255.255.255 Class B 172.16.0.0—172.31.255.255 Class C 192.168.0.0—192.168.255.255

If your HDR 24/96 is connected to a network that never “touches” another network, i.e., not publicly available outside of your network, you may use any IP address range you choose. However, research and consideration in this matter should be conducted to prevent any unwanted breaches of security and IP address conflicts.

Hub

A Hub is an active device that is designed to connect several Ethernet devices in a “star” network. Each device connects to the hub, and the hub routes communication among the devices by sorting out destination IP addresses. If you already have a network, you probably have a hub. If you wish to connect the HDR24/96 to a computer which is already connected to a network or which you regularly use to connect to the Internet, a hub would be a worthwhile addition to your system, allowing you to have all the cables connected all the time.

Important: When connecting through a hub, do not use a Crossover cable. Hubs are designed to use standard cables.

10BaseT vs. 100BaseT

The recorder’s Ethernet card is hardware configured to operate at 100Mbps. If you wish to connect an HDR 24/96 to an existing Ethernet network that is configured for 10 Mbps transmission rates, it is necessary to use a 10/100 autosensing hub and/or a rate converter. Most hubs today are autosensing.
