Important information is stored in the internal ROM.
This command can initialize the internal ROM. 'When LAN access becomes out of condition,
a power supply is re-started after this command is executed by USB communication, it will be initialized.

4-5-7. Data read time
The read-out time of data is based on the processing time of an internal microcomputer, and the speed
of the communications department. However, since this counter uses the interface to LAN, and DMA
of a microcomputer, it is downloadable at high speed (a maximum of 1MB/(second) or more).
（data acquisition method）
For high-speed download, not only a raw counting data, but also a hexadecimal number conversion data
is saved. If it is only raw data store, it can save at the interval for 1 ms or more.
However, the hexadecimal number conversion takes longer time (about 10 msec is required for 48 times
of 32-bit conversion). For example of CT48-01E case, if 10000 data are acquired in 1 ms, a hexadecimal
data is not downloadable unless it waits for 90sec (= 10ms x 10,000 - 10sec) after the completion of an
data acquisition (after 10 seconds). When a data is acquired every 10 ms, since a hexadecimal translation
is also finished to the quit of a data acquisition, and a simultaneous, it can download immediately.
Although a status changes with a model or data volume, please take care of the data acquisition,
if the interval is about 1ms.
You can confirm by the command "GSTS? (section 4-5-2)" that it is in the middle of the data conversion
to hexadecimal number. If the reply of this command became "Gate mode OFF", a hexadecimal
conversion was completed.
