Each VNC 325 codec has an integrated web interface. One codec in the VN-Matrix system must be designated as the system controller , and the contr oller can be any unit in the system, whether it is configured as an encoder or decoder . All normal system configuration and control is via the web interface of the designated contr oller . Using a comput[...]

Highly efficient compr ession algorithms — The VN-Matrix 325 system uses a minimal amount of data to transport video and audio across the network. NOTE: It is crucial to the effective operation of VN-Matrix 325 that suf ficient data throughput be achieved, especially wher e multiple sources ar e encoded. The network efficiency is dir ectly affect[...]

Data T ransport Methods Source (video) data fr om a VNC 325 encoder can be distributed to multiple decoders and displays (one-to-many) or to a single decoder and display (point-to-point). Video data is transported from the sour ce (encoder) to the display (decoder) using one of three methods, in order of pr eference, which ar e detailed in the foll[...]

This is the recommended transport method for r eal time video and audio data over an IP network. However , because RTP is a connection-less protocol, data delivery is not guaranteed. Where data packets ar e lost (such as due to excessive network traffic), the PURE3 algorithm carefully manages the data str eam to minimize any image disruption. NOTE:[...]

Unicast TCP The unicast TCP data transport method uses standard TCP pr otocol and should be used for single point-to-point transfer of data only . This method is connected as shown in figure 5 . NOTES: • Multiple decoder connections are theor etically possible using this method but not recommended. Each additional connection cr eates extra loadin[...]

Low-level Network Configuration Before connecting a LAN port (see item d or item e on figur e 2 and on page 6) on any VNC 325 to the network, you need to establish the network settings of each unit. Y ou also need to select one codec in the VN-Matrix system as the controller and designate that codec, by its IP address, in each codec. All normal sys[...]

6. T ype the default passwor d config and press <Enter>. The connected unit downloads the configuration menu (see figure 10 ). NOTES: • The IP addresses and other variable shown in figur e 10 are for illustration only and may not match those on your unit. • Many menu selections are not available if DHCP is selected. Select option 1 or 11 [...]

Configuration Selections NOTES: • In a typical installation, you: • Must change the addr ess ( 2 or 12 ), netmask ( 3 or 13 ), gateway address ( 4 or 14 ), and controller IP ( 7 ). • May need to change the boot method (1 or 11). • Most installers do not need to change the other selections. If you do change settings, note the existing values[...]

LAN Port Specific Options Option Function Comments 4 and 14 gateway: Set the IP address of the default gateway . • Gateway values must be set on the str eaming port otherwise no streaming status is available in the HTML network interface. The default gateway must be on the same subnet as the port to which it is assigned. Manually enter the gatew[...]

Making Remaining Connections RS-232 Over LAN Port If you want the VN-Matrix units to pass serial data or control signals, such as for serial control of a pr ojector , connect RS-232 devices to RS-232 Over LAN port on all codecs that are hosting contr olled or controlling devices. Figur e 11 shows how to connect a host device to the pass-through dev[...]

After the low-level configuration described on page 17 , system configuration and operation is via the network interface (built-in HTML pages) of the unit designated as the controller . The pages can be viewed by a[...]

4. Enter the Username and Password. NOTES: • The VN-Matrix 325 codecs have two valid usernames: • admin — allows full r ead/write access to all setup parameters. • public — allows r ead-only access to setup parameters. • As shipped from the factory , the passwor d for both usernames is the same as the name itself (the password is “adm[...]
