RS485 TO ETH ( B)
Finally, I need to remind that if the device is connected, in addition to the network port
parameters set according to the above, the correct serial port parameters must also be set.
Mainly, the baud rate of the serial server needs to be consistent with the baud rate of the user's
device. After this setting, the user equipment can send data to each other through the serial
ports of the two serial port servers.
6 . 1 . NETWORK PHYSICAL CONNECTION
The serial server can use a crossover cable or a direct-connected network cable to connect
to the switch or directly connect to the computer network port.
After the connection is established, the first step is to check whether the Link light is green,
otherwise, please check whether the network cable is connected.
6 . 2 . NETWORK TCP CONNECTION
When the device is used as a way to dynamically obtain IP, it cannot be directly connected
to the computer network port. Because there is no DHCP server available (generally a DHCP
server is a router in the LAN). So please specify the IP when connecting directly. At the same time,
the computer also needs to specify a fixed IP.
Configured in the same network segment
Whether it is directly connected or through a switch, when configured as a static IP, the
device and the computer need to be in the same network segment (unless it is cross-gateway
communication) , as shown in Figure above.
Since Vircom supports searching and configuration across network segments, the IP address
that can be searched but cannot be communicated is generally not configured properly. In this
case, you can use Vircom to configure the device in the same network segment.
