When
installing VisuaLCN on a Windows NT/ 2000/XP system, which user
account should I work from? VisuaLCN
can be installed from any user account that has Administrative privileges.
This is to ensure that full access to all drives, registry, and
other system resources can be obtained. The installation program
will need full access to the SOFTWARE folder in HKEY_LOCAL_MACHINE
section of the registry.

After installing VisuaLCN,
no circuits are showing up in the Network Overview Window. How is
this remedied?
Start the Configuration component and go to Server Settings page,
make sure the Number of Communication Devices and Highest Module
Address for each of them are correct. Configuration example: if
you have two communication ports and COM2 is attached to the network
adapter then set the Communication Devices to 2. Set the Highest
Module Address of COM1 to 0 then the Highest Module Address of COM2
should be set to 8 if the module addresses are 1 through 8. Once
Everything has been correctly entered restart Server then Client.

Will a VisuaLCN upgrade also require upgrades to the computer system
and Bitrode circuits?
VisuaLCN upgrades may require firmware upgrades to the Bitrode circuit
modules running on the VisuaLCN network. For information regarding
affected computer systems, see the FAQs for Operating
Systems and Computer Hardware. top

| Upgrade
Questions |
When upgrading VisuaLCN from a previous version, I want to be able
to continue running tests that are incomplete. Can this be done?
This
can be done provided the existing version is not earlier than 1.13.
If you are currently running tests you have to flush the data buffers
and stop the tests first. You can upgrade by following explicitly
the instructions that are in the manual. Please refer to Upgrading
VisuaLCN from Previous Versions in the Installation section of the
instruction manual.

After adding more modules/circuits to the network,
the new circuits are not showing up in the Network Overview Window.
How do we make them display?
First, make necessary changes in Server Settings page in Configuration
Component, modifying the Highest Module Address. Restart the Server
and the Client. Then in the Client go to the Menu bar and select
Configuration >> Add a New Circuit, this will show a list of all
the available circuits. Add them to your configuration.

Under
which operating systems will VisuaLCN run?
Since version 338a of VisuaLCN, the software has successfully been
tested with Windows 95/98/Me and Windows NT/2000/XP.
With the upgrade of the Windows Sockets version from 1.1 to 2.0,
VisuaLCN software, revision 4.06a or newer, will no longer run in
a Windows 95 operating environment. Support for VisuaLCN products
on the Windows 95 platform will continue until 15 February 2005.
For more details regarding system support, see Bitrode's
Software Support Policy.

What is
the difference between cycles and loops?
Loop
counters are reset to zero whenever the limit condition describing
the loop counter is met. If a limit condition is in one step of
a loop of steps that reads as such: "If Loop Counter #1 = 3 then
go to Step 99" (where step 99 is outside the loop), each time
the program passed through the step that contained the above limit
condition, loop counter 1 would be incremented by 1. When loop
counter 1 reached a value of 3 the loop would exit. If the same
loop was then re-entered later in the program, the loop counter
would be reset and the loop would run another 3 times before exiting.
The cycle counter, on the other hand, never resets during the
course of the program. Using the above example with cycle counters:
"If Cycles = 3 then go to Step 99", would perform similar to the
loop counter above for the first three cycles through the loop.
However, if the loop was then re-entered later in the program,
the cycle counter would not be reset and in fact will increment
to 4, which will have the effect of immediately exiting to step
99. This means that Loop #1 will be executed 20 X 40 X 3 times,
Loop #2 will be executed 40 X 3 times and Cycles will be executed
3 times.
The
following screen shot shows a basic example in Program Editor
It demonstrates a 4 step program that loops back from the second
step to the first step 20 times, then loops from the third step
to the first step 40 times within each cycle.

How does temperature compensation work?
Temperature
compensation requires an entry of a number of millvolts and a
number of degrees of temperature. This option allows the user
to define a reference temperature and a voltage setback increment
in milli-volts to achieve temperature control. The feature works
by taking the reference temperature, comparing it to the running
temperature of the circuit, and reducing the control voltage value
for the constant voltage charge step. The amount of setback is
determined by the number of milli-volts entered for the temperature
compensation value and the difference in degrees between the temperature
reference value and the actual temperature of the running circuit.
The
following screenshot shows Temperature Compensation with a value
of 50.0mV and Temperature compensation of 25 degrees.

Based
upon the above example program, if the temperature is 30ºC
and your voltage is at 25.00v, the voltage will be adjusted down
by 250mv to 24.75 volts.

| Fault
Indications |
What do the different fault indicator icons mean and what actions
should be taken when they appear? |
| |
Calibration
Fault - (NOTE: This fault applies only to the Bitrode
Model MCN) The calibration process has failed for this circuit.
The module is unable to run current, or has current flow problems.
Current and/or voltage entry fields are incorrect or the operator
has not entered a current value within five minutes from the time
he started running current. Depending on the symptom, correct
the problem then press the "Stop/Restart Range" button this will
reset the property page, then restart the process. |
| |
Calibration
Invalid - (NOTE: This fault applies only to the Bitrode
Model MCN) The module is not calibrated and must be calibrated
before it can run. |
| |
Fault
- (NOTE: This fault applies only to VisuaLCN Lab Client Software)The
circuit hardware is unable to maintain constant current, voltage
or power and has stopped running. Check: battery cables, connections,
fuse, module hardware then continue test. |

Error
Messages
Error
messages may contain module numbers and module types which may vary
from one computer and network configuration to another they are
entered here only as examples. |
What does it mean if
I receive the error message "FetchDataLine failed to get data from
module 1" followed by "Dataline from module 1 is not CR terminated"
There is a communication problem. If power management is enabled
it needs to be disabled. First go to system BIOS and disable power
management for the PC devices. Then, if Power Options icon in the
Control Panel is available for your Operating System, please use
it to disable Power Management on the Operating System level. If
the problem still persists it is advised that you purchase a Digi
board which is a high speed communication port with large buffer.
Please contact Sales at Bitrode Corporation.

What does it mean if I receive an Error Message From Server stating
"Failed to load a program 1 from database >\>"
then another message stating "A record is not unique in the Program
Info Query for the Program Unique 1 in database <path>\>"?
If you are using Client on a remote computer, make sure that the
VisuaLCN folder on the Server and all Client computers is shared
with full access, because otherwise the Server can not detect the
program database.
top |
What does it mean if I receive the error message "Failed to receive
message size from the server. Last Error Code 0" followed by the
message "Failed receive message size from the server. Last Error
Code: 10053" followed by "Connection failed"?
The Server has already reached the maximum number of Clients. Make
sure you do not have too many sessions of client running. To purchase
more licenses contact Sales at Bitrode Corporation.

Failed to receive message size from the server. Last Error Code:
10054
Lost connection with server. Make sure the Server has not been closed.

Sometimes I receive the error message "DBACCESS ERROR - Record Set
is at EOF "End of File". HEADER: Database Name: C:\VisuaLCN\Data\filename.mdb
Query Name: TestDataQuery" when I open the database with Quick Data
View. Why is that?
There are no samples stored in the Data Set that Quick Data View
is trying to read. This will occur, for example, if the user sets
the sample rate in the program to every 10 minutes but tries to
open Quick Data View 5 minutes after test is started. For more information
on this please refer to sections 8.9 and 8.10.5 of the software
manual.
