5. Operation
5.1 Default Settings
After the initial installation and setup, the MT312-104 does
not require adjustments for optimum performance and will
work trouble-free without user intervention.
Following are the default settings:
RS-232 Ports: 9600 baud,
8 data bits+ 1 stop bit,
No parity
Sensors: ....... Trigger Level 18V
De-bounce 250 ms
Relays: ......... Open
IR Ports: ....... Modulation 38 kHz (IR1 and IR2)
All Memory Blank (FFs)
5.2 Output Power
The MT312-104 provides DC voltages for powering
external devices. Check the specifications of the external
devices and make sure they do not exceed the output
ratings on the Neutron.
5.3 IR Control
IR devices can be controlled using 3 different methods with
the Neutron Controller. The first method uses an IR
receiver like the Altinex AC301-103 connected to the IR IN
pin of the controller. This method allows a user to aim a
remote control at a wall-mount or other receiver and have
the remote control's signal redirected to the IR emitters
connected to the IR1 and IR2 pins.
The next 2 methods send IR data from internal memory or
RAM to IR1 or IR2 and allow the control application to send
IR command strings from Altinex's IR library directly to the
Neutron Controller using AVSnap. These command strings
are stored on the computer application side, not within the
Neutron.
The third method uses IR commands stored in internal
memory to control the external devices. This method only
requires the control application to tell the controller to recall
a command stored in a specific memory location. The IR
commands may be uploaded into memory directly from
Altinex's IR library using AVSnap.
See the IR section for details on setting up and using the
IR outputs.
5.4 Relays
The MT312-104 has 2 relays that can be used to control or
trigger devices like projector screens. The relays can also
route power to low-power DC devices, but make sure to
verify the load requirements against the relay
specifications.
The state of each relay can be recalled by a control
application to determine the state of external devices
connected to the relays. See the Relay section for details
on using the relay.
5.5 RS-232 Control
The MT312-104 has two bidirectional RS-232 COM ports
available to communicate with virtually any serial device.
Each port can be individually set with different baud rates,
parity, stop bits, and data bits allowing a control application
to operate different devices from a single remote location.
See the RS232 section for details on setting up and using
the RS-232 COM ports.
5.6 Sensors
The MT312-104 is designed to work with a wide variety of
sensors, including motion sensors, IR detectors, RF
detectors, etc. Altinex offers the following optional sensors
that work for the most common applications and provide
excellence performance.
AC301-101 - Ceiling Occupancy Sensor
AC301-103 - IR Receiver
AC301-105 - Occupancy Sensor
The controller has two sensor inputs that accept sensor
output voltages up to 24 VDC. Each sensor input has an
independent trigger level setting that can be used to
determine if a sensor has been "tripped" or "activated"
based on movement, occupancy, etc. depending on the
type of sensor. Each sensor also has an individually
programmable de-bounce time that can be used to prevent
false sensor "trips" being detected by the control
application.
The control application does not need to query the status of
the sensor inputs to determine if the trigger level has been
reached. The Neutron automatically sends status changes
to the host application. Otherwise, the application must
periodically query the Neutron and request the sensor
status manually. The application can then take actions
based on the status of the sensor.
See the Sensor section for details on setting up and using
the sensor inputs.
