4.9.3 Video Input Levels
Video Input level is expected to be 1 volt P-P although a higher and lower signal voltage may be tolerated by adjusting the
video level control in the GUI. See
“Brightness: [0-255]” on page 6-6
for a possible work around for low level video.
4.9.4 Audio Cable Recommendation
It is recommended to utilize double or triple shielded 75 Ω coaxial cables with RCA connectors or adapters for audio signals.
UL approved coaxial cables that are in general use in Cable TV systems will usually be satisfactory. Observe fire and smoke
rating of cables and the installation environment to ensure compliance with all local codes. Cables shall be routed and
connectors and adapters attached such that terminal connections are not strained.
4.9.5 Audio Port Connectors
The Audio connectors provided are RCA female type, except L/R baseband audio on HD/SD card which uses a TRS 3.5mm
female connector. This card is shipped with a 3.5mm female to 2 x RCA female adapter. Many adapter types are available
to convert these RCA connections to the type that may be encountered at a property. Use good quality shielded cable for all
audio applications.
4.9.6 Audio Input Impedance & Level
The audio input is high impedance unbalanced. Be sure to match the audio source to the DigiVu audio connection. Usually
double or triple shielded 75 Ω coaxial cables may be used with satisfactory results. If balanced audio is encountered it is often
possible to obtain good results by using only the + side of the feed.
4.10 Ethernet Network
4.10.1 Ethernet Port
A front panel Ethernet network port is provided on the DigiVu Mini 1RU version. The DigiVu 3RU versions both have the
Ethernet port on the back panel. This port is to allow local and remote access to the equipment over the internet or a private
intranet.
Information about use of the Ethernet port may be found at:
Setting port IP addresses
“Network Settings” on page 9-6
“Connecting to the Management Computer” on page 5-4
“Connecting to a Local Cable Modem” on page 5-5
The Ethernet port is DTE, similar to a PC Ethernet port and will require a crossover cable to connect to a PC. Connection to a
router or switch may be made with a standard straight through cable. Port speed is 10/100 Base-T and will auto negotiate the
connection based on the fastest common speed of the DigiVu and connected equipment.
