Control and Monitoring
All devices on the K8 bus may be controlled and monitored through a single RS-485 connection to the ESB
device. The protocol is openly published on
control system programmers. The pinout of the RS-485 port is as follows:
PIN 1
Phantom Ground
PIN 2
Phantom Power
PIN 3
Data A (+)
PIN 4
Data B (-)
PIN 5
Signal Ground
PIN 6-9 Not Used
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.
