2. Function Overview
The KNX-GW-RS232-RS485 is a gateway between the KNX-Bus
and the serial lines RS232.It can be used to easily connect devices
with serial data of both directions like multimedia equipment or
alarm systems to the KNX-Bus. Parametrization is done by the
dedicated Program RS232-Configurator.
The KNX Serial Gateway is bidirectional. It receives data telegrams
on the KNX Bus and generates serial telegrams using the internal
interface program. A new KNX telegram can also be created when
a serial telegram is received.
The KNX Serial Gateway contains 8KByte of memory (additional
memory available upon request). The group addresses for the
internal objects are defined in a project-file together with the
serial strings to use. They are then transferred over USB.A physical
address can be established using a dummy application in ETS.
The KNX Serial Gateway comes ready for operation and does not
need to be configured with ETS. Depending on which applications
are programmed, the whole address spaces can be administered
and data from the rotary switch and push-button can be analyzed.
The KNX Serial Gateway is delivered in a 6-units REG casing with
IP20.
