I cannot get the report from RMS software.

1. Try to retrieve the device's time to check if the software is connected with the device. 
2. Check if all users have their corresponding dept. assigned.
3. If problem persists, please contact your dealer for support.

What are the lists of error codes in RMS?

I encountered several error messages while using the software.

Contact your dealer for support.
1. Kindly provide screenshots of the error messages. 
2. State a detailed information about the problem as well as related settings

How to preserve all data before hardware initialization.

a. Retrieve all parameter settings, master card code and data transactions before the initialization and export the data to desired file extension. 

b. If it could not be retrieved, use the command of NDUMP to save the data within the card reader. Then start to initialize the system. 

Unable to export data at a specified time.

Check if there's any settings error. If problem persists, please send C:\RMS\PB.ini file and also the database rms_a.mdb for study.
