What is the total power output of the power supply?
The total power output of the power supply depends on the input power of the TYPE-C interface. Usually, the TYPE-C interface of a computer can provide 5V 2A output, and the USB-A port of a computer can provide 5V 0.5A output.
What if I cannot distinguish which actual port each of the 4 COMs corresponds to on the computer?
There are two methods:
1. Randomly select a COM port on the computer and send characters arbitrarily. You will see the corresponding indicator light on the right light up, and then you will know which port it is.
2. Install the RainbowLink driver. Four port names will appear in the COM list, which are consistent with the port silk screen names on the product.
Can the power output terminal be short-circuited?
Although RainbowLink has built-in short-circuit protection and overcurrent protection, try to avoid short-circuiting to prevent damage.
Are the 4 data channels independent of each other and can they communicate with each other?
The 4 data channels are independent of each other and can communicate independently with USB, but cannot communicate with each other internally. For example, RS485 and TTL1 cannot communicate.
Are lever-type terminal blocks easy to break?
The service life of lever-type terminal blocks can reach thousands of presses, so they are not easy to damage. However, the wire should not exceed 12AWG. Overly thick wires may cause deformation or damage to the compression reeds inside the terminal blocks.
