• click OK , and HyperTerminal utility will attempt to connect to
Bercut-ET ; to check the connection, type
AT
command — the
device should respond with
OK
.
When successfully connected, user can manage the analyzer using com-

6.1.2 Updating analyzer software
Attention! False actions during the software update can lead to
the device part-malfunctioning which can be repaired in the service-
center only.
The latest versions of the Bercut-ET software are available for down-
loading at
http://www.metrotek.spb.ru
site. Current software versions are
shown in the Information menu ( Bercut-ET Settings ⇒ Information ).
The order of update procedures for FPGA microcode and MCU program
does not matter. In addition, only one of those can be updated if there is no
new version for another one.
6.1.2.1 Updating FPGA
1. Connect the Bercut-ET to PC via USB (see section 6.1.1).
Check the connection using
AT
command.
2. Type in
ATR
command.
Select either system FPGA or expansion FPGA .
In the Transfer ⇒ Send File menu of HyperTerminal utility, specify
the path to FPGA microcode file (with .rpd extension) in the Filename
window and select the
Xmodem
in the Protocol window. Click Send .
Estimated duration of the update procedure is 1 minute for the system
FPGA and 4 minutes for the Expansion FPGA. If the data previous-
ly displayed on the screen has been restored, the update procedure is
completed successfully.
6.1.2.2 Updating MCU program
1. Connect the Bercut-ET to PC via USB (see section 6.1.1).
