KNX Control Interface: Crestron
CGEIB-IP

Introduction

The Crestron CGEIB-IP is a control interface by which a Crestron control system

can be coupled to a KNX installation using either RS232 or Ethernet (TCP/IP). Also,

the Crestron CGEIB-IP filters the desired information out of received KNX

messages and sends them to the Crestron control system via the same interface

(RS232 or TCP/IP), which provides the Crestron installation with live updates of the

KNX installation.

Setup

Network Wiring

o Serial Connection:

The KNX v3.1 modules only support TCP/IP communication. The RS232
interface is described here for legacy purposes.

The CGEIB-IP can be serially controlled over RS-232 via the SUBD 9 on top of
the unit. The following pins are required:

Com pin outs between Crestron COM port and CGEIB-IP RS232 SUBD 9pol.

o LAN Connection:

The CGEIB-IP can be controlled over TCP/IP by means of the LAN port. This
LAN port is automatically activated when no RS-232 cable is connected.

The LAN port starts a DHCP inquiry only after PowerOn or Reset, i.e. if a
network cable is plugged after PowerOn of the CGEIB-IP, the LAN port does
not fetch an IP address over DHCP. Thus the LAN port is not accessible in the
network.

Best practice: Before powering up the CGEIB-IP, all other connections
should be made!

The CGEIB-IP does not support POE.

 Commissioning of the LAN port

The LAN port must be connected to the network. Afterwards, the CGEIB-IP can
be powered on. In case of a direct connection of the LAN port with the PC, a
cross-link connection is needed.

On delivery, the LAN port is already configured.
By default, it is set to automatic inquiry of the IP address. To scan the network
for the CGEIB-IP, please use the Lantronix® Deviceinstaller™.

- Open the Deviceinstaller™ software.

- Click on the "Search" icon or select "Search" under the menu item “Device”

to look for devices.

Deviceinstaller™ will show you all CGEIB-IP’s in your network and report
their IP address and TCP port to communicate on.

The CGEIB-IP only configures its Ethernet port upon start up. SO, after every
change in the IP configuration (DHCP or static), make sure to reboot the
CGEIB-IP with the network cable plugged in.

NOTE: As described above, the Ethernet configuration only takes place when
no RS-232 cable I connected. Therefore, when using Ethernet to control the
CGEIB-IP, upon reboot of the unit make sure the Ethernet cable is plugged in
and no RS-232 cable is present.

Crestron CGEIB-IP KNX Control Interface

CGEIB-IP Setup

As described above (1. Functional Description), a Crestron CGEIB-IP can be setup

to communicate with other KNX units based on Group Addresses.

When using Group Addresses the Crestron programmer needs to know how the

KNX installation has been programmed exactly. He/she needs to know which KNX

objects are programmed on which Group Addresses so that the Crestron CGEIB-IP

can then directly control those Group Addresses.

With Group Address oriented programming, since an object (e.g. the state of a lamp)

can be set by multiple Group Addresses the Crestron processor might need to

monitor multiple Group Addresses to decide on the state of an object.

KNX-units send information over the network which contains the following:

 Hardware Address from the transmitting unit.
 Group Address of the function that has to be controlled.
 Data that will trigger the function.

In Group Address oriented programming, the hardware addresses are not important

for Crestron, the Group Addresses and expected data format however are. The

installer uses the Group Addresses to define what functions can be controlled by the

KNX installation. For example every controllable light zone will have at least one.

By sending a value to this address the particular function will be triggered. E.g.

sending the value 0 to this address will result in the light switching off. A group

address list shows the Crestron programmer which functions are possible and how

they can be triggered.

Extra to every group address you have information about the data - type, meaning the

format of the expected data. The type is specified by the number of bits used; the

general types are 1, 4, 8, 16, 24 or 32 Bit. The KNX installer can produce the group-

list with the ETS projection software.

This is an example of a series of Group Addresses to control two dimmers. Each

dimmer is controlled using three different Group Addresses: one for switching, one

for dimming and one for setting the value.

The group addresses themselves exist out of three numbers divided by a forward

slash, e.g. 1/0/13. The data types in this example are 1 bit (switching), 4 bit

(dimming) and 1 byte (absolute value).

The ETS software can be set to use either “triple” Group Addresses (e.g. 0/1/0) or

“double” group addresses (e.g. 0/15).

The possible values of the “triple” group addresses are: HG/MG/UG

 HG: 0..15
 MG: 0..7
 UG: 0..255

Operations & Installation Guide – DOC. 0009 KNX/EIB Control Interface: Crestron CGEIB-IP  9

KNX Control Interface Crestron CGEIB-IP

The possible values of the “dual” group addresses are: HG/UG

 HG: 0..15
 UG: 0..2047

o Inserting Group Addresses in the CGEIB-IP

Once it is clear which Group Addresses and data types are required they have to be

inserted in the CGEIB-IP. The CGEIB-IP uses an internal comparison table with the
required addresses, so it will only pass through the telegrams from and to the bus
when the Group Addresses that are listed in the table. Therefore it is required to insert
all the used addresses in the Crestron CGEIB-IP with the help of the configuration
software, KNX-Gate. To make this easier it is best to create a data file containing all
relevant information. Alternatively you can import the ETS configuration in CSV
format (export file) straight into the CGEIB-IP. It is also possible to transfer an old
project, in EGT format, from a previous CGEIB-IP configuration.

If you need more information to import ETS files, please type "F1 → Functions →

Import and export file" in the KNX-Gate software for further information.

The list will be sent from the PC to the CGEIB-IP over a direct serial connection. The

RS-232 cable must be a “full” cable – all pins connected!

Please be careful with the option “Value request on restart”. After a reset Group
Addresses marked as such will automatically be asked for their current status which
on its turn will increase the bus traffic. This however only is the case when the
CGEIB-IP is set to have no transmission limits (more info in this document). All
parameters/setting should be discussed with the KNX programmer.

When you experience problems during the upload of software or firmware,
temporarily disconnecting the KNX bus will help.

Crestron CGEIB-IP KNX Control Interface

Use KNX Gate to do the following

 Insert Group Addresses and their corresponding data type
 Change the CGEIB-IP baud rate: 9600 or 38400
 Set KNX transmission settings (Telegrams per second, Transmission limits)
 Import ETS3 project files
 Import .egt data from an older CGEIB-IP configuration
 Export tables in ETS-CSV format to allow import in the ETS. This simplifies the

creation of filter tables.

 Download the last loaded filter table from the CGEIB-IP with the option “Start

reconstruction”

 Set CGEIB-IP communication parameters like: “Transmit for received data” and

“Acknowledge for transmit”

Communication parameters

Under “Setup → Gateway setup” you can change the following options:
 Transmit for received data on KNX:

The Crestron controller will automatically receive data from the KNX units when
their values change.
Example: KNX Group Address 0/0/1 changes the value from 0 to 1 – this information
will then be transmitted to the Crestron controller. It is advised to have this “always
activated”.
 Acknowledge for transmit on KNX:
The Crestron controller receives a confirmation from the transmitted telegram, when
this changed the setting in the KNX bus unit.

Operations & Installation Guide – DOC. 0009 KNX/EIB Control Interface: Crestron CGEIB-IP  11

KNX Control Interface Crestron CGEIB-IP

Example: When the Crestron controller changes the value of the KNX group address
0/0/1 from 0 to 1, the CGEIB-IP will return this command resulting in immediate
feedback on the button. It is advised to have this “always activated”.
 Baudrate:
Choose between 9600 and 38400. It is advised to use 38400.
 Transmit limit:
Transmission limitation of telegrams: 2, 5 or none. It is advised to use 5
Important: this can influence the bus-load, for example the response speed to
Crestron. Switching of the limiter should only be done when possible, after
verification with the KNX installer.

Be aware that adjustments to checkboxes described above need to be uploaded with
the address list to confirm the adjustment.

More information on these options can be found in the KNX software.

Note

Minimal software requirements: Microsoft.NET Framework 2.0 or
higher. (Freely available from the Microsoft website)
The CGEIB-IP should be loaded with firmware 7.03. Every CGEIB-IP
can be updated with this firmware via the KNX-Gate software.
(Firmware Gateway_Flash_C7v03.H86)

Installation

 Attach the Crestron CGEIB-IP to the DIN rail.
 Connect the serial or the CAT5 cable
 Connect the KNX bus
 Connect the power source to power up the CGEIB-IP

Crestron CGEIB-IP KNX Control Interface

Operation

Main Module: Crestron KNX IO v3.1

The “Crestron KNX IO v3.1” module deals with the CGEIB-IP communication. The

module communicates via TCP/IP with the CGEIB-IP. To configure the module the

user should fill in the correct IP address and Gateway ID. The Gateway ID is used to

associate the IO module with other KNX data type modules in the program. Up to

500 KNX data type modules can be linked to one IO module This module is

ALWAYS required.

The Initialize input needs to be pulsed once to start the module. This is required to

connect the IO module with all KNX data type modules with the same Gateway ID.

Once the Initialization_is_Complete output latches high to indicate that the modules

are ready to be used.

The ConnectionStatus output provides feedback on the current status of the TCP/IP

connection with the CGEIB-IP.

Other functionality includes polling the value for all associated KNX data type

modules and enabling/disabling debug mode.

Debug mode should be turned off during normal operation.

Group Modules

Basically for every Group Address that needs to be controlled a KNX data type will

need to be inserted, no matter if it deals with control, feedback or both.

For every data-type (number of data-bits) there is a separate module. The principle is

however identical for all of them.. Every module has a parameter field that needs to

contain the Group address of the unit to be communicated with. Other signals and

parameters depend on the data-types.

Operations & Installation Guide – DOC. 0009 KNX/EIB Control Interface: Crestron CGEIB-IP  17

The different types of Data Type modules

For every different data type in the KNX system (also called EIS type) there is a

specific Crestron module, this will allow you to send or read out any specific KNX

command or signal.

KNX Control Interface Crestron CGEIB-IP

Data type 1 bit

The most used data types are binary switch functions (on/off). They are used for a lot

of different purposes like switching lamps, triggering presets, activate alarm

functions...

When the inputs for “On” or “Off” go high the required commands are triggered.

The “Status_Is_On” and “Status_Is_Off” will be triggered accordingly to represent

the status of the data type.

Data type 4 bit

The dimming data-type is a 4-bit type and is commonly used to control dimmers.

The 4 bit module requires the usual address parameters. Dimming speed is set

standard to 1 although the KNX has 7 different dimming speeds. Speed 1 (slow) is

standard as this proved to be sufficient. The feedback shows the dimming up and

dimming down activity only, not the light level.

18  KNX/EIB Control Interface: Crestron CGEIB-IP Operations & Installation Guide – DOC. 0009

The feedback is independent from the dimming speed. Even when an KNX button

panel controls the same dimmer with a different speed the feedback will still be

produced.

Data type 1 Byte

The 1 Byte values are being used for all sorts of things with KNX, however in most

of the cases it is used for controlling dimmer with absolute values (e.g. level 70%).

Therefore the KNX 1Byte module requires an analog value on its input, it also gives

out an analog value as feedback:

Crestron CGEIB-IP KNX Control Interface

Every change of the input signal will result in a string being sent out. It uses the

lower 8 bits of the analog signal. The value of the input signal should therefore range

between 0 and 255. The analog input signal can be generated by an Analog Initialize

symbol (see above).

Also the output signal ranges from 0 to 255 (low byte).

Data type 2 Byte

The 2 byte data type is almost identical to the 1 Byte data type. In this case however

the value to be controlled and read out is 16 bit (0d to 65535d). 2Byte modules are

mostly used to read out analog values like temperature.

The module also offers inputs and outputs to use the EIS type. EIS5 is a KNX data

type that is commonly used to send a 2 Byte decimal value to the KNX system.

E.g. Set the “Set_EIS5_Value” input to 2550 to send 25,5 to the KNX system.

Values to set the correct temperature (1800d, 2200d) depend on the KNX device.

Operations & Installation Guide – DOC. 0009 KNX/EIB Control Interface: Crestron CGEIB-IP  19

Data type 4 Byte

The 4 byte module is almost identical to the “Crestron CI-KNX 2 Byte v1.6”

module. In this case however the value to be controlled and read out is 32 bit (0d to

4294967295d). SMPL windows only supports 16 bit analog signals so the 32 bit

value is split into two 16 bit signals. These signals represent the 16 high and low bits.

The module also offers a signed and unsigned and Floating Point serial outputs to

display the 4 Byte value.

KNX Control Interface Crestron CGEIB-IP

Data-type 14 Byte

The 14 byte module sends and receives ASCII text messages from the KNX

network. With this module you can request a status (e.g. “Door open”) or send text to

a display (ex. Radio RDS text). If the strings being sent are less than 14 bytes then

the module will automatically add “zero” bytes.

Polling

The challenge when working with a KNX system is that feedback signals are not

always generated automatically for every change on the network.

E.g. a dimmer can have multiple group addresses via which it is controlled. It can,

for example, use 3 addresses: One to switch on/off (1 bit), one to dim up/down (4

bit) and one to create a level-feedback value (absolute value – 1byte).

With every action the light level can change, so the momentary level feedback

should also change when dimming takes place. One can choose to not get live

feedback as such, by deselecting the “Transmit for received data” checkbox (page 9-

10). Therefore, KNX Data Type module contains a digital input called “Poll_Value”

for polling the value for the KNX data type.

Crestron CGEIB-IP KNX Control Interface

When the “Poll_All” input of the “KNX IO v3.1” module is pulsed, the module polls

for feedback of every used Group Address. The answer is processed by the normal

group modules and appears at the particular feedback output.

The “Poll_All” input should only be used at the start of the program to sync all KNX

modules.

Use the “Poll_Value” inputs on the KNX Data Type modules to poll for individual

values once the program is started.

Polling is only possible if you enable the “Read” flag in the ETS software.

Problem Solving

No Ethernet communication on CGEIB-IP

Recently we have been working with the manufacturer of the CGEIB-IP to include a
more Crestron friendly web interface. This web interface will make it possible to set
up your CGEIB-IP with group addresses by using only your web browser. That way,
there will be no need to connect to your CGEIB-IP with the KNX-Gate software.

Since our older CGEIB was completely sold out, we already released the CGEIB-IP
with the original web interface. This web interface can be used to set up the TCP-IP
communication with the CGEIB-IP, but does not allow you to set up the device with
group addresses. You’d still need to use KNX-Gate to set the group addresses via RS-

232.

Now, there has been a wrong shipment of CGEIB-IP’s that included a beta version of
our new Crestron friendly web interface. You will not be able to connect to these
CGEIB-IP’s via TCP-IP. We will describe how to roll back to the original web
interface and set it up for TCP-IP communication.

Note that the CGEIB-IP has two separate firmwares. One firmware defines the web
interface; the other defines the Crestron communication. This document describes
how to roll back the web firmware to the original web interface. The Crestron
firmware still needs to be 7.03 and can be uploaded with the latest KNX-Gate
software.

1) Please use the Deviceinstaller™software to examine the Ethernet address of

the CGEIB-IP. By default it is set up as DHCP, so it should be assigned an
address by the DHCP server automatically. In Deviceinstaller™, select
„Device“ → „Search“ to autodiscover the CGEIB-IP.

2) Use your web browser to browse to this IP address. In case your browser

displays a web interface as the one below (with a Crestron banner) the web
firmware of the CGEIB-IP needs to be updated.
