4 Port USB to DB9 RS232 Serial Adapter Hub

This product will be the internal RS232 data package, through the data reorganization at the same time to a few from the mouth to send. So the baud rate sent by the host to send baud decision. Data can be transmitted in both directions. As the characteristics of the distributor, the host can simultaneously send data to the four ports, the first machine to send data, not at the same time to send. Two independent from the mouth to send data need to pay attention to the time interval.

The input of this product is DB9 female. The pin is defined as: 2 Send. 3 receive. 5 to.

Output from the mouth with DB9 foreman. The pin is defined as: 3 Send. 2 receive. 5 to. (That is, analog computer serial output sequence).

 

product features:

1 · 1 way main port (9 holes or female port) 4-way from the mouth (9-pin male port)
2 full hardware design, support any baud rate and any protocol format;
3. Data transmission and reception data delay 0MS; input level to meet RS232-C, the output level to meet RS232-C. In this case,
4 can be more than one cascade;
5, can achieve a host control multiple slaves;
6, can achieve more than one host control a slave;
7. Automatic output after power-on, without any switch
