Introduction

KD-CX800 is a control over IP device with three multi-function control ports supporting
bi-directional RS-232, IR out (emitter), IR in (sensor or hardwire), voltage trigger, or
voltage sensor.

About KD-CX800

KD-CX800 is very flexible, with four supported modes of use:

› Mode 1: Control gateway for Enterprise AV Over IP system

» Enables more third-party control options than other HD Over IP systems
» Accepts commands from third-party control systems or Compass Control

®

» Supports generic RS-232, TCP/IP, and IR Key Digital matrix switching command

strings

› Mode 2: Compass Control® Master Controller

» Supports communication to/from licensed iOS and Android devices
» Flexible port configuration (IR, RS-232, trigger, sensor) set in

Compass Navigator™ program

» IR learner/sensor built-in
» Supports up to two real-time bi-directional RS-232 ports
» TCP/IP device control direct from iOS/Android controller – no ports used

› Mode 3: Third-Party Control via KeyCode Open API

» Cost-effective control expansion with advanced third-party control systems
» Adds reliable hardware interface to network-based control apps
» Enables IR, RS-232, and voltage device control
» Robust API allows for bi-directional communication

› Mode 4: Control Extension via IP

» Carry any supported combination of IR, RS-232, and voltage triggers over the network

› IR command sequence:

»X, Video Mode, Y, Video Mode

» X = Output / Rx number
» Y = Input / Tx number

» X and Y may be up to 4 button presses (1 – 9999)
» X may be 0 to switch all outputs
» Y may be the UP or DOWN keys to select the next or previous Input
» Y may be the LEFT key to select the pass-thru input (ie 1 to 1, 2 to 2, etc) for

the entire system

» Must be used with “0” as value for X (all outputs)
» If system has more outputs than inputs, the pass-thru begins at

input 1 again

Load completed Enterprise AV system file into KD-CX800

Mode 2: Compass Control® Master Controller

› KD-CX800 can be used as a Master Controller for Key Digital’s Compass Control®

system

› KD-CX800 lives on the network and communicates with iOS or Android controllers to

execute IR, RS-232, TCP-IP, or Voltage control commands and sends status values of
connected bi-directional devices for a rich GUI.

› I/O ports, 1, 2, and 3 are configured in any possible type according to the loaded

Compass Navigator project.

› Use as many KD-CX800 units as needed. Can also be used in combination with

other Compass Control master controller units

› KD-CX800 does not support loaded scheduled events or the Compass Control Zigbee

remote.

» Use model KD-MC1000 if those functionalities are needed.
