5.9 Interfaces Description
Besides the basic version of SmartFlex router there are available versions with one of the
following interfaces:
SWITCH interface
RS232-RS485/422 interface
5.9.1 SWITCH interface
The three LAN ports of the SWITCH interface for SmartFlex routers (RJ45 connectors for
connecting Ethernet devices) act as a typical switch device. This means that the router reads
Ethernet frames (data packets on an Ethernet link) from any port on the SWITCH interface and
transmits them on other ports of the SWITCH interface. Each port can transmit frames inde-
pendently on the other ports. State indication is displayed separately on each connector. These
router versions comply with the standards and temperature ranges stated in Chap.
for having a lower maximum operating temperature, which is +70 C.
