USB to RS-232 Communication
1. DCD 2,RXD 3, TXD 4, DTR 5, GND 6, DSR 7, RTS 8, CTS 9, RI
1. Data Communication Failure
a. Check the USB cable connection
b. Make sure that the RS-232 output interface connection is correct
c. Check the power supply
d. Check the wire terminal connection
e. Check receive indicator and see if it ashes
f. Check send indicator and see if it ashes
2. Data missing or incorrect
a. Check to see whether the data rate and format at both ends of the communication
equipment is consistent.
