Logging access activity
By connecting the AdderView Matrix’s serial port to a computer, a time stamped
log of the AdderView Matrix’s activity can be generated. This is useful for
applications where it is necessary to keep track of which users have accessed
which computers. A simple data logging program, called XPLOG.EXE, may
be downloaded from the Adder Technology website (www.adder.com). This
enables the activity log to be saved to a le or printed to a printer. This logging
program uses the Excel-compatible le XPRODATA.CSV to cross reference the
port and user information to computer and user names in order to generate an
informative activity log.
To make use of the activity logging features
1 Download the program XPLOG.EXE from the support section of the Adder
Technology website.
2 Follow the instructions in the section Saving and restoring conguration
settings to create the Excel compatible le XPRODATA.CSV that contains a
list of user and computer names and port numbers.
3 Copy the XPRODATA.CSV le into the same directory as the XPLOG.EXE le.
4 Run the XPLOG le using the following command format:
XPLOG {activity_log_destination} {com_port}
where:
• {activity_log_destination} is the le name where the
log is to be stored or the word PRINT if the log is to be printed on a
printer attached to the computer’s parallel port. LPT1
• {com_port} is the computer’s serial port that is connected to the
AdderView Matrix. Options are 1 (for COM1) or 2 (for COM2).
For example:
• XPLOG datalog.txt 1
would log activity information received on COM1 to the le datalog.txt.
• XPLOG PRINT 2
would print activity information received on COM2 to the printer
attached to the computer’s LPT1 printer port.
These programs will run continuously until you press .
More information
If you wish to integrate activity data logging with your own applications, contact
Adder for a list of serial data logging codes and their associated meanings. It
is possible to use the activity logging and AdderView Matrix synchronisation
features together but this requires a specially constructed serial cable. Please
contact Adder for further details.
Display Data Channel (DDC)
The industry standard Display Data Channel feature allows the AdderView
Matrix to discover the capabilities of a user port video monitor and transmit
that information to the connected computers. This helps to reduce incidents
where too high a video resolution/frequency signal is sent to the user port by
a selected computer, resulting in an unreadable or blank screen image. For
successful operation, it does require that the computers and their video circuitry
are congured to respond to DDC information.
When using two monitors of different capabilities
The DDC feature can use only one set of monitor specications in its
declarations to the connected computers. This becomes an issue when the
monitors connected to the two user ports have different capabilities, e.g. a
15” VGA monitor on user port 1 and a 17” multiscan monitor on user port 2.
In such cases, it is important to ensure that the AdderView Matrix samples the
lower specied of the two monitors.
To congure DDC settings
1 Press to select the on-screen menu.
2 Press to select ‘More menus’, then press again to select the next level
of ‘More menus’.
3 Highlight DDC Options and press .
4 Ensure that the DDC Function option is set to ENABLED. If not, highlight it
and press to change its setting.
5 Choose the DDC Source. Highlight this option and press to specify
a particular user port, or choose AUTO - this begins with user port 1 and
moves to the other port if a valid DDC monitor is not found.
Note: Where the two connected monitors have different capabilities, ensure
that the DDC Source option is set to look only at that port.
6 Choose an appropriate DDC Refresh setting. The setting AT START will
interrogate the monitor(s) selected in the DDC Source option whenever
the AdderView Matrix is switched on. When DISABLED, no new DDC
data is sought and existing information is used. When viewing this menu,
press F8 to perform a discover DDC information from the chosen user port
immediately.
