RS485 TO ETH ( B)
computer is: Vircom sends a broadcast query. After receiving the query, all devices will reply with
their own parameters. Vircom tools. This method searches all devices at once.
2. Manually add: There are two situations:
a) Large- scale routers divide the network : In some large- scale networks, broadcast packets
are divided by routers, so that the broadcast packets cannot reach the device end, but the ping
device IP is all connected. At this time, it generally needs to be added manually to solve the
problem. The method of adding manually is to click "Add manually" in the "Device Management"
dialog box to add the first and last IP to query the devices one by one.
b) The public network server queries the internal network equipment : the serial port server
is in the internal network and acts as a TCP server mode, and Vircom is on the public network IP
server. At this time, you need to do a 1092 UDP port mapping on the router of the network
where the device is located, and map it to the IP where the device is located, and then Vircom
manually adds the device. The IP is the public network IP of the device.
3. TCP client : When the device acts as a TCP client, it will initiate a TCP connection to port 4196
of the destination IP (116.15.2.3). After the connection is established, it will automatically send
its own parameter system to the UDP port ( note that it is not the TCP port) of the destination
port (here 4196) at each keepalive timing, so that Vircom can be able to do so on this computer
(116.15.2.3) The device is found. If the destination port is not 4196, you need to modify the
Vircom's default parameter receiving port. The method is to modify the
menu/configuration/software configuration/default listening port, and then start Vircom. If a
TCP port conflict pops up, just ignore it and continue execution.
4 . Sending parameters at regular intervals: Even in a serial server in TCP server mode, you can
check the "Send parameters at regular intervals" function, and the parameters will be sent to the
destination port of the destination IP (here 116.15.2.3) every 5 minutes. Vircom that receives
parameters on this port of this server can manage these devices.
