Local device can be connected by PC serial port through LNK-UP port to
realize network management. Address numbers of devices which are
concatenated on a PC serial port mustn
’
t be repeated. Local concatenated
devices are maximum 15pcs.

Description
Bit1 Ethernet port auto-negotiation configuration. Bit1 = OFF, Ethernet
auto-negotiation is enable.
Bit1 = ON, Ethernet auto-negotiation is disable. When the Ethernet
negotiation is disabled the port’s MDI/MDIX function is disabled too, so
when connecting to switch the straight-through cable is needed and when
connecting to NIC and router the cross-over cable is needed.
Bit2 Ethernet port
’
s speed configuration when auto-negotiation is
disabled.
When Bit1 = ON, If Bit2 = OFF the Ethernet port
’
s speed is 100M;
If Bit2 = ON the Ethernet port
’
s speed is 10M;
When Bit1 = OFF the Bit2 is invalid.
Bit3 Ethernet port
’
s duplex mode configuration when auto-negotiation is
disabled.
When Bit1 = ON, If Bit3 = OFF the Ethernet port is on full-duplex mode;
If Bit3 = ON the Ethernet port is on half-duplex mode;
When Bit1 = OFF the Bit3 is invalid.
