USR-K1 Super Port
File version: V1.0.3
USR-K1 is the high performance-cost version of Super Port .It is an embedded serial networking module,
whose function is to realize bidirectional transparent transmission between UART TTL and Ethernet .The
amazing part of K1 lies in its Ethernet port integration design .You can apply K1 to your products to realize
networking communication .User can directly process data interaction through network and device to realize
remote data acquisition, remote control and management.
K1 is based on the design concept of "Simple,Reliable,Affordable" .And it has the same kernel solution and
parameters as USR-TCP232-T.

2.2 Set-up Software
Set-up Software with link http://www.usriot.com/Download/237.html as can help to
view default setting then set the parameter.
1. Search in LAN (Firstly, ensure the computer IP is static. The module IP is 192.168.0.201by default; Disable
firewall, antivirus soft and WIFI).

2.3 Communication Test
(link http://www.usriot.com/Download/199.html ) can help you test.
Serial to net debugging tester application:
1. Ensure the COM port baud rate, check bits, data bits, stop bit correspond to module parameters.
2. Ensure network protocol, IP address, port number correspond to module parameters.
3. Open COM and the web then connect. They begin transparent transmission after choose the module IP.
