General Description
The E981.03 combines the TP1-256 physical layer, the
communication controller and two DC supply outputs
for bus powered applications. The internal power man-
agement assures KNX conformance under all load con-
ditions.
The connection between the E981.03 and the host pro-
cessor can be established by either UART or SPI compat-
ible interfaces, or in direct Analog Mode.
Applications
ÿÿ Sensors, actuators, routers, gateways,
Bus-powered or externally supplied
ÿÿ Security applications
