K8 Product Family Operating Manual

Read this section first as it explains the overall system theory of all K8 devcies in the family. Additional
manual sections contain the details for specific model number.

K8 Series Overview

K8 is a digital audio distribution system. It allows for the transport of 16 digital audio signals over a single
Category 5 cable along with control data. The audio signal travels in one direction only, from the input
device to the output device. Control data is bi-directional.

Quick Start Information

K8 devices are factory configured to begin passing audio immediately after powered up in the simple case
where 8 input channels are sent to 8 output channels. More complex settings and configurations are
possible if desired by using the K8 terminal control protocol. For example, configuring an 8 channel output
device to select channels 9-16 instead of 1-8 is done using the K8 terminal control protocol.

Using Input Devices

Input devices are used to put audio onto the K8 bus while output devices are used to get audio out of the
K8 bus.
Two 8-channel devices may be stacked up to populate all the available 16 channels on a K8 cable. For
example, 16 analogue inputs are obtained by stacking quantity (2) K8-AI8 devices.
Stacking two devices is accomplished using a standard Ethernet crossover cable to connect the K8 Out 2 of
the first device to the K8 Out 1 of the second device. The K8 Out 1 of the first device is then used to drive
the K8 bus.

Using Output Devices

TERMINATION RULE: The first and last device on each K8 chain must have their termination switches set. If
both K8 ports on a device are used, the 4 switches are on. If one of the K8 ports on a device is not
connected, the switches are off. The K8 terminal control protocol is able to monitor the termination switch
settings remotely.
