Introduction
The 16-channel network module is a network-based relay control module based on 32-bit system. The module can use the Internet or internal router to control the relay module, so as to control the electrical switch remotely and realize the purpose of centralized power management. It can be set directly through IE browsers and controls.

Application:
Home decoration, hotels, shopping malls, factories, cafes, karaoke timer management, daily office, store monitoring, physical network, industrial control equipment, test equipment power control, unattended, underground pipes, mining equipment, ships, aircraft station rooms, intelligent management and centralized management.

Be careful:
When connecting the high voltage power module, please pay attention to the wiring to prevent the short circuit from damage to the equipment.

Technical specifications:
1. external power supply voltage: 5.5VDC 2A
2. access: 16
3. electronic switch life: 100000 times
4. working temperature: -30~85 C.
5. size: 47 * 48 * 20MM

Explain:
1. set IP in the Internet property.
2. default IP 192.168.1.4 port: 30000

View relay status command
Http:// IP / Port / 99:16 ACSII feedback the current I / O state. MSB is used for the first place and LSB for sixteenth bits.
E.g: Return 1111000011110000 indicates that relay 1-4 is ON, relay 5-8 is OFF, relay 9-12 is ON, and relay 13-16 is OFF.
Modify IP
Http://IP/Port/41: When modifying IP, Relay-01 cannot be 0, Relay-01? 04 cannot be greater than 255. Port cannot be 0.
Restore the default
When the button is short, the LED will flicker once.
Press the button long, do not untie until LED lights up. Then release the button and LED will go out. It says it is to restore factory settings. IP 192.168.1.4 and port 30000
