The picture below is a serial device server of TCP232-410 . It have 1 RS232 and 1 RS485,
they can work independently, now we are going to test it's RS232 function.
Diagram 2 - 1 TCP232-410 with case
Power 410 with DC5V adaptor(make sure you can supply at least 200mA current at DC5V)
Connect 410's RJ45 to PC directly with network cable( No need to distinguish cross or direct
connect cable ), or connect the module and PC via switch or router and set the PC's ip address to
192.168.0.201(must be a format of 192.168.0.xxx), netmask 255.255.255.0.
Connect 410 and PC's comm port together, with a standard female-female extend
cable(default cross-over cable).
Here is TCP232-410's default net configuration ,
IP address: 192.168.0.7
Subnet mask: 255.255.255.0
The default gateway: 192.168.0.1

To test briefly in default working mode, on the foundation of the hardware connection, use
the matched software USR-TCP232-Test to make transmit t ing and receiving test. The left side is
serial port, use software default settings, the right side is the network part, set to TCP Client and
server to be IP 192.168.0.7, port 23.
By default, the two COM port to be set as TCP Server mode, port is 23/26.
This illustration shows the 10 ms two-way simultaneous automatically transmit screenshots.
As the allocated memory of the display control is limited, in order to test large amount of data
transceiver, here will suspend the receive display, only statistical data. Below is the effect after
testing for a few hours, and transmit t ing millions of bytes. Stable and reliable, without a byte loss.
