Gateway BACnet - KNX
GATEWAYS
Description
The Ekinex® BACnet - KNX Gateway performs a protocol conversion between a
BACnet and a KNX TP network. Two versions are available: BACnet MS/TP (master-
slave / token-passed) over serial RS485 network and BACnet IP over Ethernet. The
device integrates a KNX bus communication module and it is suitable for mounting
on a 35 mm DIN rail; it requires an auxiliary power supply.
Main features
• Plastic casing
• Connection to bus line with KNX terminal block
• Installation on 35 mm rail (according to EN 60715)
• 4 modular units (1 MU = 18 mm)
• IP20 protection degree (installed device)
• Weight 145 g
Technical data
• Power supply: 8...24 Vac or 12...35 Vdc
• Absorption at 24 Vdc: 3,5 VA
Communication
KNX side
• KNX TP (Twisted Pair) communication port electrically isolated from power supply

120 ohm termination resistance pluggable by a 1-way microswitch
• BACnet communication
• Selectable baud rate from 1200 to 115200 baud
• BACnet objects exchange
• 1440-byte volatile support “BACNet image” memory buffer
BACnet side (IP version)
• Ethernet communication port (IEEE 802.3), RJ45 connector, minimum cable
category: 5E.Communication BACnet slave
• BACnet objects exchange
• 1440-byte volatile support “BACNet image” memory buffer
Configuration
