2) Manual add: divided into two cases:
Figure 47 add manually
a) Large routers split the network: in some large networks, the broadcast
packets are split by the router so that the broadcast packets cannot
reach the device, but pinging device IP is enabled. At this point, you
generally need to manually add to solve. The method of manual addition
is to click "manual addition" in the "device management" dialog box to
add the first and last IP to query the devices one by one.
b) Public network server query internal network equipment: the serial server
in the internal network and as a TCP Server mode, zlvircom in the public
network IP server. At this time, a port mapping of 1092 UDP should be
made on the router of the network where the device is located, which is
mapped to the IP of the device. Then, zlvircom will manually add the
device, and the IP is the public network IP of the device.
3) TCP Client: when the device is a TCP Client, it initiates a TCP connection to
port 4196 of the destination IP (116.15.2.3). When the connection is
established, each hold time automatically sends its own parameter system to
the UDP port (not TCP) on the destination port (4196 in this case,), enabling
zlvircom to search for devices on this computer (116.15.2.3). If the destination
port is not 4196, the default parameter receiving port of zlvircom needs to be
modified by changing the menu/configuration/software configuration/default
listening port, and then starting zlvircom will ignore the execution if TCP port
conflict pops up.
