KNX IP Interface 731
(Art. # 5242)
Compact bus powered Interface between LAN/Ethernet and KNX Bus
KNX IP Interface 731
Application
The KNX IP Interface 731 serves as a universal interface for PC
or Laptop to the KNX bus. The KNX bus can be accessed from
any point on the LAN. The KNX IP Interface 731 can be used as
a programming interface for ETS® from ETS 3.0f. For access via
KNXnet/IP Tunneling max. 5 simultaneous connections are
possible.
The IP address can be obtained by a DHCP server or by manual
configuration (ETS) respectively. Power is supplied via the KNX
bus.
Installation and Connection
The KNX IP Interface 731 is designed for installation on a DIN
rail with a width of 1 unit (18mm). It features the following con-
trols and displays:
The KNX IP Interface 731 is powered by the KNX bus. An exter-
nal power supply is not necessary.
The device is not working without KNX bus power.
KNX programming mode
The KNX programming mode is activated/deactivated either by
pressing the flushed KNX programming button
❸
or by simulta-
neously pressing the buttons
❼
and
❽
.
Status display
The KNX LED
❹
lights up green if the device is successfully
powered by the KNX bus. The LED indicates telegrams on the
KNX bus by flickering.
Communication failures (e.g. repetitions of telegram or telegram
fragments) are indicated by a short change of the LED color to
red.
The IP LED
❻
lights up when an Ethernet link is active. This
LED is green if the device has valid IP settings (IP address, Sub
net and Gateway). With invalid or nonexistent IP settings the
LED is red. This is also the case if e.g. the device has not yet
received the IP settings by a DHCP server. The LED indicates IP
telegrams by flickering.
The Mode LED
❺
can visualize the status of each KNXnet/IP
tunneling connection. With the buttons Conn Up/Dn
❼
❽
you
can chose each single connection. Conn Up
❼
counts the
connection numbers up and Conn Dn
❽
down. The actually
selected connection number is indicated by flashing (1x…5x) of
the Mode LED
❺
. An available KNXnet/IP Tunneling connec-
tion is indicated by a green LED and a used tunneling connec-
tion is indicated by an orange LED.
Via the Escape function (Esc) this indication can be ended by
simultaneously pressing the buttons Conn Up/Dn
❼
❽
.
If neither programming mode nor manual operation are active
the Mode LED
❺
can visualize configuration errors.
