1Product Overview
1.1 Product Introduction
IEM615 series are layer 2 managed embedded industrial Ethernet switch modules
with the features of high integration, small size, rich functions, simple and convenient
operation. This series include following port types:
5 100M Ethernet ports, support 10/100Base-T(X) copper port and 100Base-FX
fiber port.
2 TTL UART ports, expandable RS-232/485/422 serial port, support serial port
server function of serial port to Ethernet.
2 TTL CAN ports, support the CAN server function of CAN to Ethernet
bidirectional transparent transmission.
1 CONSOLE port for command line coordination and module debugging.
2 I/O alarm ports for expandable relay alarm.
