Input devices are used to put audio onto the K8 bus while output devices are used to get audio out of the
K8 bus.
Output devices may be daisy chained until the maximum cable length of 200 meters has been reached.
Output devices are passively connected and do not refresh the K8 audio signal. This architecture has the
benefit that a failure of an output device will still allow audio to pass to the next device in the chain. Daisy
chaining devices introduces no delay in the audio signal.

Connecting a Control System

The status of all K8 devices in a system may be remotely controlled and monitored through the RS-485
port on the input device. The control signal passes through the same cable as the audio signals and
requires no special installation. The protocol is openly published on
software engineers and control system programmers.

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.
Some K8 devices are connected to the PC with an RS-485 port and some are connected with an Ethernet
port. It is possible to purchase a USB/485 adapter. Please refer to the section of the manual for this
specific device.

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.

How are the cables terminated? 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? How do I get 16 audio channels on the K8 system when the input box K8

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.

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.
