Support SNMP to Modbus RTU protocol. Only those with -snmp tails
support this feature.
Support the ability to access devices in any network through P2P
across technology. This feature is supported in model N with trailing
patches.
4.5 TCP communication test
After the device parameters are configured, TCP connection communication can
be tested with serial port tools and TCP debugging tools.
Figure 9 TCP communication diagram
Now suppose the PC COM port (USB to RS232 line) connect with serial port of
serial device server, then open the serial debugging assistant ZLComDebug, and
open the corresponding COM as figure 10; Open TCP&UDP debugging assistant
SocketTest, and as TCP client, fill in the destination IP for the serial port server IP
(currently 192.168.1.200), destination port is 4196, and then click "open" button in
figure 11. Enter "socket send" in SocketTest and click send, then the data is
transferred to RS232 interface through the network port of the serial port server,
and then sent to ZLComDebug, which is then displayed in ZLComDebug.
Conversely, type "Comdebug send" in ZLComDebug, and clicking send can also
be sent to socket test and displayed.
The demonstration demonstrates the data transparent forwarding function from
serial port to network port, network port to serial port.
