Product Introduction

This product is resistant to high temperature and can work in an environment of-40℃-85℃.

Strong anti-interference ability, can be connected with external high current AC contactor and relay, and will not crash under strong electromagnetic interference.

The real 100m speed enables reliable communication under the condition of sending commands with zero delay.

Industrial products. You can automatically obtain IP addresses.

Ten TCP client connections are supported on the TCP server.

Through the configuration software provided, you can configure five working methods: TCP server, TCP client, UDP server, UDP client, and DNS domain name.

Electrical parameters

1. Power supply DC 5V, DC socket input power supply, DC connector specification 5.5-2.1mm (outer diameter-inner diameter) with 5.5-2.5MM input will lead to poor contact. When the power is off when the light is off, the communication cannot be connected.

2. The operating temperature range of the board is-40℃ to 85℃.

3.1 relay output, output without voltage. The DC rating of a single relay is 10A, the AC rated current is 10A, the maximum AC rating is 250V, and the maximum DC rating is 30V. Do not exceed the rated value during use, and leave margin during use. The relay has three contacts, which are normally open (NO for product screen printing), normal closed contact (NC), and common contacts (COM).

4. The device is equipped with power-down storage function, which can save the status of the relay and can be configured through configuration tools.

5. Reset the configuration. The RESET position of the screen label is to restore the factory setting button. Steps to Restore factory settings: power off first, then press and hold the reset button, then power on the product, release the button after 10 seconds, and then power on again. The default IP address is 192.168.0.105.

Working mode introduction

         The working mode is configured with the provided configuration software.

1. TCP server

In this mode, only TCP clients can be used to connect devices, and 10 TCP clients can be connected.

2. TCP client

In this mode, the device actively connects to the TCP server (the remote IP address and remote port number are the parameters of the device connection). Only one server can be connected.

3. UDP server

In this mode, any UDP communication is supported.

4. UDP client

In this mode, only UDP communications that match the remote IP address and remote port number (set software settings) are supported.

5. DNS domain name

In this mode, the device uses a TCP client to connect to the TCP server bound to the domain name (the port is a remote port).

Command explanation

   AboveCommands are sent and received in characters.The command does not contain enter or spaces..ASCII is required for 16-digit sending.The code table is converted by itself.

Obtain the device name

           Send:name

           Return:name="HHC-N1O"

           HHC-N1OIt is the device name. You can use the configuration tool to configure it yourself.

OpenCircuit relay

           Send:on1

           Return:on1

Close the relay

           Send:off1

           Return:off1

    Delay control

For example, if relay suction is requiredRelease it after 2 seconds, you can send the following command

     Send:on1:02

     Return:on1

The above instruction indicates that the relay is closed.Release After 2 seconds, on1: indicates the relay to be controlled, followed by the delay time, up to 99 seconds.

Read relay status

        Send:read

        Return:on1

        When the relay is open, the return ison1, when the relay is in the closed state, the return is off1.
