This manual covers the ESML3-FL2-D4 series. The KBC ESML3-FL2-D4 products are
high performance, managed, five port industrial Ethernet switches with an
embedded four port serial data servers. They are designed for use in a wide range of
operating temperatures in non-environmentally conditioned, industrial applications.
Redundancy is offered through the DT-Ring technology that recovers cable or port
failures automatically in less than 50ms. The unit has redundant power supply
terminals and an alarm output for power supply and uplink port failure.
1.1.1
ESML3-FL2-D4
The ESML3-FL2-D4 is a five port managed switch which provides three, 10/100
twisted pair copper ports, two uplink, full-duplex, multimode or singlemode 100Mbps
fiber ports. Each copper port supports a self-adaptive function allowing it to be
configured to 10Base-T or 100Base-TX, full or half-duplex operation mode,
supporting automatic MDI/MDI-X connection. The two fiber ports can be used to
make up a ring network with a recovery time of less than 50ms. The embedded
server has four serial data ports that can be individually configured to work with
RS232 or RS485 protocols. The switch is available as either a DIN rail or wall-mount
configuration.
