For ZLVircom software, the remote manage can be performed as long as the device can be
searched in the device list. The remote manage for device can be divided into the following
situations:
1) Automatic search: the device and computer are under the same switch, at this time
whether or not in the same network segment, way of ZLVircom searching devices on the
computer is: ZLVircom send broadcast queries
all devices reply the ZLVircom tool
with own parameters after receiving the query. This method searches all devices at
once.
Figure 59 Auto Search
2) Manually add: it is divided into two situations:
Figure 60 Manually Add
a) Large router segmenting network: in some large networks, broadcast packets are
segmented by routers, so that broadcast packets cannot reach the device end, but
ping the device IP shows all connected. At this point, you need to manually add it.
The manual addition method is to click "Add Manually" in the "Device Manage"
dialog box to add head and tail IP then you can query the device one by one.
b) The public network server queries the intranet device: the serial device server is in
the intranet and as the TCP server mode, zlvircom is on the server of the public
network IP. Here need to make a UDP port mapping of 1092 on the network router
the device in, mapping to the IP the device in, then zlvircom manually add this
device, IP is the public IP in device side.
3) TCP client: when the device is a TCP client, TCP connection is initiated to port 4196 of
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 not the TCP port) of the destination
