Ak Host Remote Control Mode - TESTO CU-2 User Manual

Fig. 5.3: log-in window
Even if the testo CU-2 system is started by default with the standard user 'Matter' without a
password needed, administrator rights are required for remote desktop operation.
An administrator account is created by default with both user name and password: Administrator
(mind the capital letter at the beginning of the password).
If you try to log-in as 'Administrator' for the first time after system startup, i.e. if the standard user
'Matter' is logged in, the message shown in Fig. 5.4 appears.

Confirm by clicking 'Yes' to log-out 'Matter' and change the user to 'Administrator'. After logging in
the testo NanoMet software is automatically started in the manual operation mode described in
chapter 5.3.1 with the control menu shown in Fig. 5.2.

AK Host Remote Control Mode

Using testo CU-2, the particle number measurement system can be integrated in a test rig. The
testo CU-2 Digital Control Unit can then be controlled by a host computer connected by serial
RS232 port or Ethernet connection. Communication protocol is AK over TCP/IP or RS232.
Detailed AK protocol specifications can be found in chapter 7.
A second host computer can be connected via Ethernet optionally. Only one of the host
computers can control the connected devices but the second one is able to read data using
AK 'A' commands.
The testo NanoMet software has to be in the Manual Operation Mode which is the default mode
after system start up. Then the AK master computer (Host A) can send remote command 'SREM'
to get priority. The testo NanoMet user interface will then be deactivated (software control mode
not available but data still can be read and recorded) and the second host (Host B) can only
execute 'A' commands. This is illustrated in the flow chart of Fig. 5.5.
