8-way 5v relay module PC control board with indicator relay output DC / USB interface

characteristic

1. Module using USB and serial communication with the outside world, easy to module and PC, single-chip connection.

2. Module normal operating voltage of 5V, and ICSE014A (8 relay) module configuration 5V power interface

interface

All three modules are equipped with USB and TTL level serial interface. The specific configuration is as follows:

1.USB: standard micro USB port, through the USB extension cable directly with the PC and other equipment to communicate.

2. TX: Serial interface sender.

3. RX: Serial interface receiver.

4. 5V: Positive power supply.

5. GND: Power ground.

6. 5V power outlet: ICSE014A only, USB power supply is insufficient.

Instructions

1. USB use method

The module is connected to the PC via USB. The connection is as follows:

Then open the "Relay Board Manager" to control the module directly. See "RelayBoardManager_Reference" for how to use the software.

2. Serial use

The module can communicate directly with other devices via the serial port. The connection is as follows:

Module can receive the single-byte command issued by the host computer (baud rate 9600):

Host computer 0x500x51

ICSE012A0xAB

ICSE013A0xAD

ICSE014A0xAC

When the module receives 0x51 after entering the normal working state, the module receives a byte of data will be directly control the relay start and stop. Each bit of the data controls the relay ('0' for the start, '1' for the stop). For ICSE012A (4) and ICSE013A (2), only the lower 4 bits and the lower 2 bits are valid, and the other bits
