Problems and troubleshooting

1. Data communication failure

A. Check to make sure USB cable is OK.

B. Make sure RS-232 output interface connection is correct.

C. Make sure power supply is OK.

D. Make sure the wire terminal connection is OK.

E. Make sure the indicator lights flash when receiving.

F. Make sure the indicator lights flash when sending.

2. Data missing or incorrect

A. Check to see whether the data rate and format at both ends of thecommunication equipment are consistent.
