Serial port cable *1 Diagram 1.1.1-1 Testing Tools 1.Test purposes: Test to realize the USR-K6, have a basic understanding of USR-K6 Test to know whether there are some thing wrong with it. 2.Data direction: Diagram 1.1.1-2 Data Direction Jinan USR IOT Technology Limited

1.1.2. Hardware Connection To test the conversion from serial port to ethernet, we put the serial port of K6 connected to PC via serial cable. Connect the interface of the K6 and PC using net cable. After testing and found no mistake, powered for K6. Diagram 1.1.2-1 Hardware Connection Note: the power adapter and the cable are from USR 1.2. Network Testing To prevent the thing that occurs when the custom use the K6 such as finding no server, can not ping and can not enter the webpage, after connecting you should check the PC before testing. 1)Shut down firewall and antivirus software....

Serial port baud Serial parameter None/8/1 Form 1.3-1 Default Parameters 1.4. Data Transport Testing Then the serial port and ethernet can communicate bi-directly, steps are as fellows: ① Open the”USR-TCP232-Test.exe” and connect the hardware as the Diagram 1.1.2-1 Hardware Connection ② Select the TCP server mode in the “Net Setting” . Fill the PC IP into the server IP, server port 8324, click to start listen and build TCP client. Baud rate:115200, serial parameters:None/8/1, then click to open the serial port.

2. Overview 2.1. Brief Introduction USR-K6 is a tiny size serial port to Ethernet module which can realize the bi-direct data transparent transmission between RJ45 port and TTL serial port. It can be applied to RS232 and RS485 by level conversion circuit. Supports low power consumption, only consume a little current in full speed work. Equipped with Cortex-M0 core, fast speed and high efficiency. Supports several functions to meet more need. K6 is easy to operate and have strong compatibility. On the basis of adding new functions, it is compatible with the setting protocol of K5, which...

Used as indication pin for TCP connection status. If the LINK function is enable and connected, this LED will light. Connected to the IP of the user’s MCU, reset when abnormal, reset when the pin reach 200ms When normal working , don’t connect the pin or connect to using serial high level. Under low level, the pin is used for module configuration, access to power then pull down“Reload” pin Refer to 4.4.3 Factory Reset Net port data instr Single chip data indicator foot, when data transport in the network, it will flash.

4. Product Function Here are the functions of K6, below is the overall block diagram. Jinan USR IOT Technology Limited

4.1. Network Basic Functions 4.1.1. IP address/ subnet masks/ gateway 1. IP address is the identity representation of the module in the LAN, which is unique in the LAN, so please be sure there is no another device same as it in the LAN.  Handle to setting. Note fill the IP, subnet masks and gateway. Static IP adopted to the environment that required to statistics the IP and the device and makes them correspond one to one. Advantage: accessing the device that can not distribute IP address can be searched via UDP broadcast. Disadvantage: different net segment in the different LAN can not...

Get IP address , gateway address, DNS server and other information from the gateway server to easy the step for setting IP address, DHCP adopted to the environment that have no special requirement to IP. Advantage: accessing the device equipment with the DHCP server such as router can communicate directly. Reduce the hassle of setting IP address and subnet masks. Disadvantage: accessing the device with no DHCP server such as computer directly, K6 can not work. 2. Subnet masks used to determine the host number and the network number, indicates the number of subnet and determine the flag...
