1 Application
The KNX LineMaster 762.1 secure combines the essential functions of a KNX bus line: KNX power
supply with choke, KNX IP router and KNX IP interface. In addition to the bus voltage the power
supply offers an auxiliary voltage.
The KNX IP router in the KNX IP LineMaster 762.1 secure allows forwarding of telegrams between
different lines through a LAN (IP) as a fast backbone. Using the embedded KNX IP interface, the
KNX line can be connected directly to a PC (e.g. by ETS). The device supports KNX Security
which can be enabled in ETS. As secure router the device allows coupling of not secured
communication on KNX TP to a secured IP backbone. Also for the interface functionality
(tunneling) KNX security prevents from unauthorized access. The IP address can be obtained by a
DHCP server or by manual configuration (ETS) respectively.
This device works according to the KNXnet/IP specification using the core, the device
management, the tunneling and the routing part. The KNX IP LineMaster 762.1 secure has an
extended filter table for main groups 0 to 31 and is able to buffer up to 150 telegrams.
2 Installation and connection

2.1 KNX programming mode
The KNX programming mode is activated/deactivated either by simultaneously pressing the
buttons (P) ❺and ❼.
When the programming mode is active, the programming LED ❽lights up red.
2.2 Manual operation and status display (device display)
The red LED ❽on the front of the device is used to indicate KNX programming mode and errors.
Summary of the states of the programming LED ❽:
2.2.1 Startup and idle display
During startup of the device, the individual address and the state of the application is displayed.
The device name “KNX IP LineMaster” can be changed within ETS parameter settings.
The state can take one of the following values:
▪Running: The application is loaded and running.
▪Stopped: The application is stopped (programming LED ❽flashes)
▪Unloaded: The application is not loaded (programming LED ❽flashes)
▪Loading: The application is being loaded by the ETS
▪Overload: The output current exceeds the overload threshold 900 mA
(programming LED ❽flashes)
LED Status
Meaning
LED lights red
The programming mode is active.
Errors are not shown by the LED, but can be read in the display.
LED flashes red
Error conditions:
▪Overload (sum of current from auxiliary and
bus voltage output).
▪The device is not loaded correctly
e.g. after aborting a download.
The programming mode is not active.
LED is off
The device operatres in normal operating mode.
No error condition is active.
The programming mode is not active.

▪Manual: Parameterized coupler settings were overwritten manually via manual operation in
the device display (filter, retransmit and acknowledge). A long press on button enter ❼
restores the normal operating mode as parameterized.
The power supply function (KNX –and auxiliary voltage) is independent of the state of the
application.
After 10 minutes of no activity, the device switches to the screen saver (blank screen
with a jumping dot) to increase the lifetime of the display. Pressing any key turns the
display back on.
2.2.2 Main menu
Pressing the button down ❺calls up the main menu of the device. By pressing button enter ❼
you call up the submenus. Within the menus, use buttons up ❹and down ❺to navigate, the
button enter ❼to confirm and the button escape ❻to go back or up one level.
The main menu offers the following menu items for selection:
▪Router
▪Powersupply
▪System Info
▪Dev Reset
▪Contrast
2.2.3 “Router” menu item
The Router menu item offers the following submenus for selection:
▪IP Config
▪IP Tunnel
▪Filter
▪Operation
▪Transit
▪Bus Errors

2.2.4 “IP Config” submenu
Select DHCP or Manual for the IP configuration. Within Manual, you can set the IP, Subnet and
Gateway. Use buttons up ❹and down ❺to navigate and button enter ❼to select.
2.2.5 “IP Tunnel” submenu
The KNX IP LineMaster 762.1 secure supports 8 simultaneous KNXnet/IP tunneling connections.
In this submenu their current state and their individual KNX address are displayed.
2.2.6 “Filter” submenu
For commissioning or test purposes, the filter settings parameterized with the ETS can be
temporarily bypassed here. The settings for broadcast telegrams (BC), individual addressed
telegrams (IA) and group telegrams (GA0–main groups 0 to 13 and GA14 –main groups 14 to 31)
can be changed separately. The left side concerns the forwarding from the main line (IP) to the
subline (TP), the right side concerns the forwarding from the subline (TP) to the main line (IP).
The following selection options are available:
▪Forward: –
▪Block: x
▪Filter: \

Settings that deviate from the parameterization are marked with a square bracket. The
parameterized setting can be restored with a long button press on button enter ❼.
2.2.7 “Rep / ACK” submenu
In this submenu the settings for repeating telegrams on the subline (TP) can be changed. The
settings for broadcast telegrams (BC), individual addressed telegrams (IA) and group telegrams
(GA) can be changed separately.
The following selections are available:
▪No repetition: ---
▪Up to 3 repetitions: REP
In addition, the settings for the telegram acknowledgement (acknowledge) on the subline (TP) can
be changed:
▪Confirm only when routing: ROUT
▪Always confirm: ACK
▪Negative confirmation: NACK
If the response is NACK, access to the device via KNX TP is no longer possible, see ETS
parameter settings.
These settings are temporary.
Settings that deviate from the parameterization are marked with a square bracket. The
parameterized setting can be restored with a long button press on button enter ❼.

2.2.8 “Tel Counter” submenu
This submenu contains telegram counters. The number of forwarded telegrams can be read here
separately according to direction (main line IP to subline TP and vice versa) and telegram type
(individual addressed telegrams IA and group telegrams GA). The counters can be reset here.
2.2.9 “Bus Errors” submenu
In this submenu errors during KNX communication are displayed. By pressing button enter ❼the
error counters can be reset under the navigation item RESET COUNTERS.
The following errors are counted:
▪Send (error while sending)
Send failed after last retry because ACK, NACK or BUSY responses are missing.
▪Rcv (Error while receiving)
Deformed telegrams or telegram fragments received.
▪Repeat
Number of repeatedly sent or repeatedly received telegrams.
2.2.10 “Powersupply” menu item
The Powersupply menu item offers the following submenus for selection:
▪Diagnosis
▪History
▪Bus Reset
▪Ev Counter

© 2022 WEINZIERL ENGINEERING GmbH Seite 9/38
2.2.11 “Diagnosis” submenu
This menu displays the current values of busload (%), voltage (V), current (mA)
and temperature (°C).
The busload is a measure for the number of telegrams in a certain period of time.
100 % busload is reached at approx. 50 telegrams per second (Group Value Write
telegrams with 1 byte). The voltage shows the current value of the bus voltage, the
current the sum of bus and auxiliary current. The temperature is measured in the
device.
2.2.12 “History” submenu
The history shows the value range (min. and max.) for busload (%), voltage (V), current (mA) and
temperature (°C) of the last 24 hours.
Pressing button down ❺several times displays a graphical representation ("real time") for the
following values: Busload, voltage, current and temperature. The time span of each graph is
approx. 2 minutes.
To return to the main menu, press button escape button ❻.
2.2.13 “Bus Reset” submenu
In this submenu, the KNX line can be reset. By pressing button enter ❼the KNX bus voltage is
switched off. The maximum reset time is 30 seconds. This time can be shortened by pressing
button escape ❻.

2.2.14 “Ev Counter” submenu
Various operating states are automatically logged in the device, which can be read in this
submenu. All times are displayed in the format “hours:minutes”.
▪Op. time [h:m]
Total summed up operating time of the device.
▪Run time [h:m]
Time since the last device restart.
The time restarts when the operating voltage is applied.
▪Restarts [count]
Number of device restarts.
The counter is incremented when the operating voltage is applied.
▪Time [h:m] > 75 °C
Summed operating time during which the temperature in the device was above 75 °C.
▪Time [h:m] > 640 mA
Summed operating time during which the current load was higher than 640 mA.
The current load of both outputs is recorded.
▪Time [h:m] > 900 mA
Summed operating time during which the current load was higher than 900 mA.
The current load of both outputs is recorded.
In order to extend the life of the internal memory, the values of the counters are stored
in the memory in a dynamic time span of up to 8 h. Thus, the values - if the power
supply to the device was interrupted - can fall back somewhat.
