passive tags in range. Few seconds after the motion stops, everything turns OFF. This delay after the motion
stops is 5s + the value of the EMD parameter (which is set by default to 0s).
C) In the most complex scenario, the “Field” LED does not immediately indicate that an enabling command was
sent to the LF and / or the passive tags reader. It will actually wait first for a confirmation signal from the
installed transmitters that they are actively started reading tags, and only then it will turn ON. This provides
for an extra level of confidence and feedback for the user. For example, if something is defective and the LF
field level is significantly below the programmed level, the “Field” LED will blink intermittently instead of
steady red.
The table below indicates the possible combinations depending on the parameters PEX, PPS and PFB. For more details,
please refer to the MBD40 Rev A user manual:
Field LED Truth Table:
PEX PPS PFB Field LED
N N N Always ON
Y N N On when exciter provides valid feedback
N Y N On when triggered by motion sensor, no feedback is expected nor
required
N Y Y On when passive reader provides feedback
Y Y N On when exciter provides feedback & triggered by motion sensor
Y Y Y On when exciter and passive reader both provide feedback signals
5.4. Operation
The operation of the MC30RG is controlled by commands and parameters. The parameters values are set into
MC30RG during the configuration session. This configuration is controlled by a PC running a serial communication
program like ProComm or HyperTerminal, through a serial communication link type RS485. There are several specific
commands to configure or to query the MC30RG parameters values.
Each module inside MC30RG has a unique address called NetId. It is strongly recommended to set the same NetId for
all the modules inside a portal, although this is not necessarily required. The NetId is an integer in the range 0 to 127
and is a good practice to clearly mark it on the front label in the designated area. By default all Lyngsoe modules
installed in an MC30XX portal have NetId = 1.
The Lyngsoe modules inside the portal can be controlled by sending commands that follow this general syntax:
<identifier><NetId><space><COMMAND> <ENTER> where <type> is a single character that is specific for each
module type.
