Lauer Extension
The Lauer Extension is a new SCOM command specially developed for Lauer Nav-
igation Monitors. It extends the standard SCOM command set with more powerful
functions, which add special remote configuration, controlling and status capabilities
to each device.
Like the MCC command, the LAU command is a container for specific sub-
commands and their parameters. They are encapsulated within the DATA field of the
command stream. In contrast to standard SCOM commands, a message returned in
a response to Lauer Extension command does not always contain the command itself.
This means, a response message may contain the same data for different commands.
Therefore, a response message should be processed immediately, after the command
is sent.
The LAU command exposes the capabilities of a monitor model through SCOM.
While there is a base set of sub-commands, which are always supported on each mon-
itor model, there are also sub-commands, which may expose the special capabilities
of a device, not available on other models.
The full LAU sub-command set is divided into three functional groups:
For any LAU sub-command, the following command and response streams are gen-
erally common:
Command Stream
Group Purpose
CONFIGURATION Allows to query for or change the current device configuration.
CONTROL Intended to control a device or its hardware extensions, such as
buzzer, I/Os etc., during operation.
STATUS Used to query for the current device or hardware extension status,
such as IP address, buzzer state, analog/digital inputs etc.
