16 Channel Wifi Relay Module

Specifications:

• Just control via Serial Port from your computer

• Supports 802.11b/g/n protocols
• Supports WEP/WPA-PSK/WPA2-PSK/TKIP/AES Wireless Security

• Supports AP/STA
• Supports TCP Server/TCP Client/UDP Server/UDP Client Modes
• No driver required, just use as a normal serial port from your computer
• Dimensions: 115mm x 130mm x 19mm
• Low power Wifi Module
• Compared with traditional dynamic domain name plus router port mapping this device has incomprable superiority by eliminating the need for users to apply for a dynamic domain name, it makes frequent operations, such as port mapping on the router, so the device has plug and play capabilities.

Electrical Specifications:

• Input voltage: 5V
• Input current: 2A (Recommended Power Supply: https://tinkersphere.com/power/1114-5v-2a-dc-power-adapter-55mm-x-21mm.html)
• Max Input voltage for relay: 200V
• Max input current for relay: 10A
• Ouptut channels: 16
• Default IP address: 192.168.16.254
• Default port: 8080
• Cascaded network number: unlimited

Usage:

• When first powered up,  the modue will setup an access point named HI-LINK_XXXX, where XXXX changes module by module. The default password to the SSID is 12345678.  To configure the module, first connect the PC to the access point created by the module HI-LINK_XXXX, and then point the browser to: http://192.168.16.254/ser2net.asp.

• We can then configure the network setting, and serial port setting.

•  The P2P device is referred by to the uuid and password. To find out the uuid and set the password, point your brower to: 192.168.16.254/p2p.asp  when we connect the PC to the access point created by the module HI-LINK_XXXX.  The browser will prompt for username and password to access the configuration page, where the default  username 'admin', and password is 'admin'.

• We can then control the relays using the app by referring to the uuid, and provide password.

Downloads:

• MCU Source files, the MCU bridges the serial port of the wifi/ethernet module (in p2p mode) to the 16 relays.
  • Protocol:
    • In total there are 16 relays
    • Send:23 2a 31 30 01 62 2a 23 Turn on relay 1, and return 8 bytes:61 61 31 30 01 62 62 62
    • Send:23 2a 31 20 01 52 2a 23 Turn off relay 1, and return 8 bytes:61 61 31 20 01 52 62 62
    • Send:23 2a 32 30 01 63 2a 23 Turn on relay 2, and return 8 bytes:61 61 32 30 01 63 62 62
    • Send:23 2a 32 20 01 53 2a 23 Turn off relay 2, and return 8 bytes:61 61 32 20 01 53 62 62
    • while [2]+a[3]+a[4]=a[5], for example：31+30+01=62
    • Inquiry：
    • Send：23 2a 4f 01 01 51 2a 23 to check the status of the relay, and return 18 bytes of statues
    • If return ：23 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 02 20 2A That means all relays are turned on, it starts with 23, and ends with 2A, b[1] means relay 1, b[2] means relay 2...... b[15] means relay f，b[16] means relay 0，b[1]+b[2]+......b[16]=b[17];
    • if return：23 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 01 10 2A That means all relays are turned off, it starts with 23, and ends with 2A, b[1] means relay 1, b[2] means relay 2...... b[15] means relay f，b[16] means relay 0，b[1]+b[2]+......b[16]=b[17];
