INTRODUCTION

• Thank you for purchasing the LIVE SNAKE 24.12. The transmission distance of the unit reaches 100 meters using CAT5 cable and over 1000 meters using fiber cable. It delivers uncompressed digital audio in high quality, extra low noise, andreal-timee through a standard Ethernet network. The audio transmitting setting can be set by professional software and saved in the unit for use independently which makes them more flexible and economical. All of the signals are sent through the Ethernet network in digital which overcomes the disadvantage of distorting the audio caused by sending signals in the analog signal. It reduces the system installation and maintenance fee as the unit is suitable for any situation and transmits signals throughthe  Ethernet network. The unit also can be remote-controlled through unit discovery software.
• We suggest that you use this manual to familiarize yourself with the features applications and correct connection procedures for your LIVE SNAKE 24.12 before using it. This will help you avoid problems during installation and setup.
• We are confident that you will enjoy your unit.

CONTROLS

FRONT & REAR PANEL

1. Power LED
   The indicator lights up when the power is turned on.
2. Link LED
   In Dante mode, two machines need to be connected. This LED indicator indicates whether the Dante connection is successful or not. If the connection is successful, the indicator lights up.
3. MIC Input Jack
   The Digital Snake System equips 24 microphone preamplifiers for use with all types of microphones. The preamplifier has a Class A input buffer which is followed by a dual-servo gain stage. This arrangement will bring ultra-low noise and wide gain control which help to boost signals without increasing unwanted background noise.
4. Analog output channel
   XLR jack for outputting analog signal.
5. Power Switch
   Push the top part of the switch to turn it on and the bottom part to turn it off.
6. AC input
   Used for AC input
   Note: 100-240V-50/60Hz. Fuse: T1.6AL AC250V. Power consumption:40W
7. DANTE port
   • There are two DANTE ports labeled “primary” and “secondary”. Only the primary Ethernet port needs to be connected,b ut if both ports are connected they become a redundant fail-safe. That is, if the primary port loses communication, the secondary port quickly takes over. Careful network design and topology which takes advantage of this feature can provide extremely high reliability in critical applications.
   • Each Ethernet port is equipped with two LEDS. The yellow LED of the Secondary Ethernet port will light to show you that the Ethernet port can be used after powering the Digital Snake System. The green LED of the Ethernet port which conis nected will flash if the data is transmittingROUBLESHOOTING

About CAT 5

Category 5 cable (Cat 5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BAST-T (Gigabit Ethernet). Cat 5 is also used to carry other signals such as telephony and video. The cables are commonly connected usingpunch-downn blocks and modular connectors. Most Category 5 cables are unshielded, relying on the twisted pair design and differential signaling for noise rejection. Category 5 has been superseded by the Category 5e (enhanced) specification.

Cable standard

• The specification for Category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These documents specify performance characteristics and test requirements for frequencies of up to 100 MHz. Cable types connector types and cabling topologies are defined by TIA/EIA-568-B. Nearly always, 8P8C modular connectors, often referred to as RJ45, are used for connecting category 5 cables. The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed in an installation so long as the same scheme is used on both ends of each cable.
• Each of the four pairs in a Cat 5 cable a has differing precise number of twists per meter to minimize cross-talk between the pairs. Although cable assemblies containing 4 pairs are common, Category 5 is not limited to 4 pairs. Backbone applications involve using up to 100 pairs. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and cross-talk from other pairs.
• The cable is available in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Permanent wiring (for example, the wiring inside the wall that connects a wall socket to a central patch panel) is solid core, while patch cables (for example, the movable cable that plugs into the wall socket on one end and a computer on the other) are stranded.

Maximum cable segment length
According to the ANSI/TIA/EIA standard for category 5e copper cable (TIA/EIA 568-5-A), the maximum length for a cable segment is 100 meters (330 ft). If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T of solid
-core permanent wiring, two connectors, and two stranded patch cables of 5 meters, one at each end.

Category 5 vs. 5e
The Category 5 specification improves upon the Category 5 specification by tightening some cross-talk specifications and introducing new cross-talk specifications that were not present in the original category 5 specification. The bandwidth of category 5 and 5e is the same -100 MHz.

Applications

• This type of cable is used in structured cabling for computer networks such as Ethernet over twisted pair. The cable standard provides performance of up to 100 MHz and is suitable for 10BASe-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigable Ethernet). 10BASE-T and 100 BASE-TX Ethernet connections require two cable pairs. 1000BASE-T Ethernet connections require four cable pairs. Through the use of power over Ethernet, up to 25 watts of power can be carried over the cable in addition to Ethernet data.
• Cat 5 is also used to carry other signals such as telephony and video. In some cases, multiple signals can be carried on a signal cable; Cat 5 can carry two conventional telephone lines as well as 100BASE-TX in a single cable. The USOC/RJ-61 standard is used in multi-line telephone connections. Various schemes exist for transporting both analog and digital video over the cable. HD BASE-T is one such scheme.
• Any cable that contains air spaces can breathe in moisture, especially if the cable runs between indoor and outdoor spaces. Warm moist air can cause condensation inside the colder parts of the cable outdoors. It may be necessary to take precautions such as sealing the ends of the cables. Some cables are suitable for “direct burial”, but this usually requires that the cable be filled to hinder moisture migration into the cable.
• When using a cable for a tower, attention must be given to vertical cable runs that may channel water into sensitive indoor equipment. This can often be solved by adding a drip loop at the bottom of the run of cable.
• Plenum-rated cables are slower to burn and produce less smoke than cables using a mantle of materials like PVC. This also affects legal requirements for a fire sprinkler system. That is if a plenum-rated cable is used, the sprinkler requirement may be eliminated.
• Shielded cables (FTP/S TP) are useful for environments where proximity to RF equipment may introduce electromagnetic interference, and can also be used where eavesdroppinglikelihoodd should be minified.
