Security Notes

•Installation and assembly of electrical equipment may only be carried out by qualified

electricians.

•When connecting KNX / EIB interfaces, KNX™ training is required.

•Failure to observe this instruction may result in damage to the unit, fire or other hazards.

•This guide is part of the product and must remain with the end user.

•The manufacturer is not liable for costs or damages caused to the user or third parties

by the use of this device, misuse or interference of the connection, malfunctions of the

device or other connected devices.

•The opening of the housing, other unauthorized modifications and / or conversions to

the device will void the guarantee!

•The manufacturer shall not be liable for any inappropriate use.

Commissioning

To operate the Enertex® KNX IP Secure Coupler, you need:

•Two KNX/EIB lines

Boot

When the unit is powered up, the display shows the product name.

The boot time is approximately 3 seconds. During this time, the green/red/yellow LED will start

running for a short time. At the end of the booting process the display shows "KNX Ready",

The device is supplied with power via the bus line connected to the MAIN terminal.

The green LED flashes every second with a pulse duty cycle of 1:30.

Display

After one minute the display turns off automatically. To turn it on again, press the DISPLAY but-

ton on the front panel briefly.

When the display is turned on, pressing the DISPLAY key initiates a scrolling through various in-

formation pages.

Note: t higher telegram load only a part of the group addresses is visible (approx. 3 displays

per second).

Page 2 shows the firmware version, physical address, serial number, bus voltage and status of

sub and main line

Seite 3 shows information on telegram load

Seite shows the FDSK as long as the device is not set to the secure mode.

Pressing the DISPLAY button for more than 5 seconds will block (=bypass) all filters of the rou-

ting. During this phase, the display will show a countdown until it automatically returns to normal

mode with activated filters. This function of the DISPLAY key can be blocked via the ETS appli-

cation (see section Filter blocking (bypass)).

At the front side there are three LEDs. The green LED is blinking every second with a 1:30 duty

cycle and indicates operational readiness. The red LED indicates programming mode, the yellow

LED shows bus activity.

Reset

If the device is to be reset to the factory settings, the PROG key on the front panel must be pres -

sed for 10 seconds. After this time the red LED starts blinking - then the PROG button can be re-

leased and the unit will perform the reset to factory settings.

ETS Parameter

Terms

Encryption, encrypted If devices send data information via the TP bus or IP network, they are

generally readable by third parties. These only require access to the TP bus or IP network for

reading. Encryption of the data in this context means that the contents of the telegrams are no

longer to be interpreted if the encryption parameters (for example passwords) are unknown.

Key, Key Parameter A series of numbers known only to the ETS project. These numbers are

used to transform the data in both directions: encryption and decryption.

FDSK (Factory Default Setup Key) The initial factory key. This key is used when commissio-

ning the initial programming. A new key is loaded into the device, whereby this process is en-

crypted with the FDSK. The FDSK key is then no longer valid. It is reactivated only when reset -

ting the device to factory settings.

Secure Mode If the device is parameterized via the ETS so that the communication is only en-

crypted, this is referred to as secure mode.

Plain Mode If the device is parameterized via the ETS so that the communication is only unen-

crypted, this is called unsecured mode.

Version requirements

For accurate operation of the devices in secure mode, ETS 5.7.4 or higher is required.

Topology

To insert the coupler into an ETS project as area coupler, this project must have a TP backbo-

ne. The coupler must be assigned to the address XX.0.0 (see www.knx.org), where XX repres-

ents the desired area.

To insert the coupler into an ETS project as line coupler, the main line must be of type TP. The

coupler must be assigned to the address XX.YY.0 (see www.knx.org), where XX represents the

desired area, YY the desired main line

Example with the following topology stored in the ETS:

If the device is used as a line repeater, all filters for group addresses (see below) and physical

addresses must be set to forwarding.

Device specific parameters

General

Figure 3: General settings of the device

The application parameters and filter tables of the Enertex® KNX TP Secure Couplers can be

downloaded from both the main line and the sub line. It is also possible to limit the parameter

download to the main line or the sub line or both lines. In the latter case, the device can no lon -

ger be accessed until it is reset to the factory default settings by a factory reset.

Example

TP outside line is connected to SUB, the main line to M IN. The coupler is programmed so

that only group addresses according to the filter are routed. For example, it prevents the ad-

dress of the door opener on the M IN line from being accessed by the SUB line. potential at-

tacker would be easily possible to reprogram the filter tables of the coupler. This can be preven-

ted by activating the programming lock

Filter

Physical address filter

The Enertex KNX TP Secure coupler can be configured in such a way that physically addressed

telegrams are forwarded, blocked or filtered. Physically addressed means that devices are loa-

ded or programmed across the coupler with the ETS application parameters. If this communicati-

on is blocked, for example, an actuator on the main line cannot be programmed from the sub

line.

If, additionally, broadcast telegrams are also blocked, it is not possible to assign the physical ad-

dress via the coupler using the programming button of the other device, even if the physically

addressed telegrams are forwarded by the coupler.

This applies to all communication that is related to the device address in the specified direction.

The required parameters are located in the phyiscal address filter (see Figure 7).

(e.g. programming of actuators) can

be forwarded, blocked or filtered via

routing. This applies to all communi-

cation that refers to the device ad-

dress in the specified direction.

Sub => Main filter, block, route Direction: SUB to MAIN

Blocking of broadcast tele-

grams

Broadcast telegrams (e.g. search for

actuators in programming state) can

be forwarded or blocked via the rou-

ter.
