5.4 Device Model and Command Processing
The following figure shows the basic structure of the unit under firmware aspects. The actual receiver is
isolated from the remote control units by a central data memory. This memory is at the core of the
EM510 firmware and deals with the following tasks:
Administration of connected modules (receiver, remote clients)
Making data available to the receiver (e.g. receive frequency, scan parameters, etc.)
Sequentialization of settings for simultaneous operation
Sending messages on parameter changes to all modules.

Figure 5-2: Device model with remote control
As mentioned under 5.3 "Description of Commands", the unit can be controlled from one or several
remote control units – the remote clients – simultaneously (competitive control). Upon system start, the
receiver is logged in to the data memory automatically. The remote clients are logged in if a host
computer sets up a link to the EM510.
The receiver obtains the required data (receive frequency, bandwidth, etc.) from the memory. It has no
data storage facility of its own and therefore has direct access to the central memory.
Due to the principle of competitive control, different clients can modify the same parameters. The
central memory sequentializes the access procedures (last client wins) and sends messages to the
other users that a parameter has been changed.
