2.4. Ethernet DB9 interface
MIGE1203G-GS/M-DB9 has a DB9 interface. In use, the switch DB9
interface can be led to other Ethernet terminal equipment via a network cable
(direct connection or crossover). The order of the DB9 interface pin numbers is
shown in the figure below.
Each DB9 port supports IEEE802.3x adaptive, so the most suitable
transmission mode (half duplex or full duplex) and data rate (10/100/1000Mbps)
can be automatic selection (the connected device must also support this
feature).If the device connected to these ports does not support
auto-adaptation, the port will force itself to work at the same rate as the other to
avoid full/half duplex mismatch. The transmission mode will default to half
duplex and flow control will be automatically disabled.The Gigabit port line
sequence is compatible with 100M ports, specifically between DB9 and RJ45
line sequence correspondence is shown in the figure below
