The RS232 signal of this product is transmitted through the network cable. When using this adapter, it is recommended to use it within a distance of 1-15 meters. It does not require external power supply and is simple and convenient to use.
Compared with DB9 cable, CAT5 cable can save money. Due to the thinner RJ45, the operation of the cable is easier.
Please note that it can only work in pairs (two can be used at the same time) and cannot be used alone. This cable can be converted to a DB9 9-pin serial port, which is used to the computer host or various monitors.
