•Mass memory and interruption readings must be performed according to these steps:

1.Define all parameters by writing to a Defining Parameters for Reading Values for Historic Tag.

2.Start a reading thread by writing to a Mass Memory's Reading Thread Tag. Only one thread can be started each time.

3.Check the status of this reading thread until it is finished by reading a Mass Memory's Reading Thread Tag.

4.Perform a data reading by using a Block Tag with the B2 parameter equal to 2 (two, data is only available until the next thread starts, when they are overwritten).

•To communicate via modem, it must be configured on Windows Control Panel with a baud rate of 9600 bps, and all compression and error correction options must be disabled.

•A communication test, that is, the Communication Test Tag, can also be performed manually, via HyperTerminal or other tool. To do so, once physically connected to a meter, via serial or modem, send the value "I" and a response must be received.

•A Q1000 meter provides the concept of access levels, and according to this concept, certain types of functionality are only available by providing a password linked to that level. Up to 4 (four) different passwords can be defined in a meter, corresponding to 4 (four) possible levels and, if this occurs, this password must be informed using an Access Password Tag.
