Monitoring
The Lisa devices are much more extended than a simple internet player. They feature automatic software
update, playing from card, card content update, task scheduling and more. In this section the options to
monitor the Lisa are described. This is a useful feature for a device with so many possibilities.
To monitor the Lisa in detail, the
is the tool to use. If the device is connected to a
local Windows PC via USB, the
can communicate with the device. When the Lisa
is new to you, we advise you to start with the
to learn how the Lisa behaves.
This is a good solution and has proven to work fine, but is not practical in a real-life situation where you
would have devices installed at different sites. To address this situation, the Lisa has monitoring and
(remote) control functionality.
10.1
Using Lisa Configuration Tool for monitoring and control
When a connection is available between the Lisa and the
constantly sends log messages which are displayed in the monitoring window of LCT. The LCT interface
is the same for all Lisa devices. This monitoring has much greater detail than can be derived from the
remote monitoring (see
).
With LCT you can program the device by setting the desired parameters and programming the settings
to the device. To program the settings, LCT sends a number of textual commands, which can include 1
or 2 arguments and a value. In return the Lisa will send back a textual message to indicate whether the
setting was applied.
It is also possible for LCT to read the settings of the device by sending the same commands, but in this
case without arguments or values. When the Lisa receives such a command, it returns the value(s) of the
required setting(s).
In
the complete list of commands is documented, including examples. A device
reset may be required to apply changes in settings. The Lisa needs to be powered on after a "reset",
using the “pw 1” command , or by pressing the power button on the front panel.

Remote Monitoring
For the use of the remote monitoring feature, a monitoring server is required. This is implemented on both
the Streamit Device portal and the Streamit ADP. Every “in-minutes-configurable” interval, the Lisa will
create a TCP (socket) connection with the monitoring server and send a textual log message. This
message contains a number of tags, which the server parses and displays in an intuitive way using
tables, color codes, etc. Depicted below is the current implementation on the ADP and Device portal.
