Our usb to rs232 have two categories chip: 

1340-chip program, the chip is a single IC, the output voltage is rs232 voltage (9V), non-TTL voltage (5V), can be used in industrial controls(PLC), Debug routers,  serial communication. Other  factory has non-340 single-IC chip such as the PL2303 single IC chip ,the output voltage is TTL voltage (5V), can not be used in industrial controls(PLC),debug  router , serial communication, can only be used for programming unit .

2pl2303+MAX211 program is two ic program,the output voltage is rs232 voltage (9V),MAX211 Can chage the pl2303 output voltage (TTL voltage 5V) to rs232 voltage (9V), Can be used in industrial controls(PLC),debug router,serial communication,also support MODEM,serial mouse,etc.
