Monitoring With A Pc; Category 5 Cable Color Code; Frequently Asked Questions (Faq) - Klein + Hummel K8-AESI16 Bedienungsanleitung

A limited amount of serial data tunnelling is available between the serial ports on any two devices in the system. This is
useful for passing control data to another system, such as a lighting controller or external relay box located in the same
equipment area as the K8 output box.
The phantom power is used to drive K8 accessories designed to attach to the local control connector, such as a local volume
control wall plate. Phantom power is switched off by default and must be activated through the control protocol.

Monitoring with a PC

It is possible to monitor and control the devices in a K8 system using a terminal program and the K8 terminal control
protocol. Instructions for its use are available on the website at www.klein-hummel.com.
The K8 system may be controlled and monitored using a USB port by purchasing the K8-485 USB to 485 adaptor cable.
Also, the K8 system may be controlled and monitored via IP over Ethernet by using an Ethernet to 485 converter.

Category 5 Cable Color Code

The K8 system utilizes the same cabling and pin standards as Ethernet, although K8 is not an Ethernet protocol.
K8 system cables should be terminated according to standard TIA/EIA-568A or standard TIA/EIA-568B. Both standards
create a straight through cable as long as the same color code standard is used on both ends. Creating a crossover cable is
accomplished by terminating one end as 568A and terminating the opposite end as 568B.

Frequently Asked Questions (FAQ)

What is K8?
K8 is an easily implemented and robust method of distributing digital audio and control signals across a facility or between
two audio devices with low latency and professional audio quality.
What audio format is used in K8?
Currently available products are uncompressed digital 24 bit, 48 kHz sample rate.
How many channels are available with K8?
Up to 16 audio channels may be placed on a single cat 5 cable, as two sets of 8.
How are the cables terminated?
All cables are terminated with RJ-45 connectors using the color code defined by either EIA-568A or EIA-568B as long as all
ends are terminated using the same standard.
How do I get 16 audio channels on the K8 system when the input box K8-AI8 only has 8 inputs?
Up to two input units such as the K8-AI8 (analogue line input) may be used to place audio onto the K8 bus. One of the two
input units must be connected to the system via a standard category 5 crossover cable.
How do I make a cat 5 crossover cable?
Wire one end according to the color code EIA-568A and the other end according to the color code EIA-568B. In the K8
system a crossover cable is used to stack two input devices such as the K8-AI8 onto the same cable. All other cat 5 cables
are wired straight through.
How far can you run a K8 cable?
One K8 distribution leg can be run a total length of 200 meters no matter how many devices are connected along the way.
How much delay is in the K8 system?
K8 has a total through delay of 1/2 ms. Adding K8 output devices adds no delay to the signal path because all K8 devices,
except for distribution amplifiers, are passive.
If a single K8 device fails does the whole system go with it?
No. K8 devices are passive and a single failure will not destructively affect any other device on the system.
