Step 1: Connect to the MultiTasker enclosure using RS232 at 115k baud or a TCP/IP connection; the IP address is visible on the front
panel LCD. The default IP address is 192.168.10.84 port 23.
Step 2. The MT312-104 is shipped with factory defaults but must be configured at the time of installation.
Step 3. The MT312-104 is identified by its slot number in the command section of this document.
Step 4: Use control commands to set relays, set/read sensors, read/send RS232 data, etc.
Step 5. Gather all accessories included with the Neutron MT312-104 and make terminal block connections.
- Only use the terminal block captive screws for making connections. Do NOT tin the bare wires.
- Use multi-conductor cable, 24-28 AWG, stranded wire, and make note of which equipment is connected to which port.
IR: IR data is output from internal IR memory or the pass-through IN connection; pass-through uses an IR receiver like the
AC301-103 between IN and GND on the terminal block. If needed, +12V provides power for the IR receiver.
RS232: Connect serial devices to the controller RS-232 connector. Configure the card for the correct baud rate on each port.
By default, the Rx ports are disabled to improve system performance. Use the [TRRS] command to enable.
Relays: Wire the relays directly to the external device. There are 2 single-pole-single-throw relays. Verify the load specifications of the
external device do not exceed those of the relays listing in the specification tables.

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.

communication or RS232 through the MultiTasker
enclosure.
5.7.1 Unsolicited Feedback
The MT312-104 provides feedback for the following
unsolicited events not related to a command sent to the
controller:
1) Sensor input goes above or below the trigger level
The card sends feedback to the control card.
2) Data is received on one of the RS232 ports
The card sends the data received on the RS232 port to
the control card.
Feedback Examples:

21. (RS)
This is unsolicited feedback. RS232 data received by the
MT312-104 is sent to the MultiTasker control when
received on either port. The data is not analyzed; it is
simply relayed to the MultiTasker. Data from the
MultiTasker may be accessed from either the TCP or
RS232 port. The MultiTasker’s RS232 output is 115k baud,
regardless of the MT312-104 baud rate.
Important: Make sure to configure the RS232 ports to
match the baud rate of the equipment connected to each
port. See the [MODERS] command for details.
Feedback Format: (RSndddCii)
n = RS-232 port number (n=1 or 2)
ddd = Data received through RS-232 port
Example:
The Neutron’s port 1 is connected to a projector. In addition
to controlling the projector from the controller, the
application can be used to respond to data received from
the projector; for example, "TEMP1" indicating its internal
temperature is too high. The Neutron receives the data on
port #1 (RX1) then returns the following, or similar:
(RS1TEMP1C04)
Data may be returned in any of the 3 examples below and
depends on how the data is received and string length:
1. (RS1TEMP1C04)
2. (RS1TEC04)(RS1MPC04)(RS11C04)
3. (RS1TC04)(RS1EC04)(RS1MPC04)(RS11C04)
22. [WRIR]
Save an IR command string from Altinex's IR library into
the Neutron's internal memory. A single IR command
requires 10 individual save commands of 100 characters
each. After each command is processed, the Neutron will
return acknowledgement indicating it has finished
processing the previous command.
Command Format: [WRIRxy,ddd…dCii]
x = IR memory location number (01 to 99, 2-digits)
y = Save instructions (1=Overwrite, 0=Append)
ddd = IR data in 100 hex characters
Valid characters are "0123456789ABCDEF"
Example:
An IR library command string is 1,000 characters and
requires 10 save commands to save the IR string. The
following example saves an IR string into memory location
"01". Always wait for acknowledgement from the Neutron
before sending the next command.
[WRIR011,FFFFFFFFFF...C04] Overwrite Mem 01 with
100 char.
[C04] Feedback from the
Neutron.
[WRIR010,AAA000FFF...C04] Append Mem 01 with
100 char.
[C04] Feedback from the
Neutron.
Repeat
[WRIR010,FFFFFFFFFF...C04] Append Mem 01 with
100 char.
[C04] Feedback from the
Neutron.
Note: In the above, memory locations are highlighted in
yellow and the overwrite/append in green.
23. [RDIR]
Read IR data from memory.
Command Format: [RDIRxxCnn]
x = IR memory location (2-digits 01 to 99)
Example:
Send [RDIR21C04] to read the IR data string in memory
location 21.
The Neutron responds with 10 blocks in the format
beginning with "[IR" followed by 100 data characters and
concludes with the card ID and close bracket.
[IR21,01, FFFFFFFFFFFFFF00000000000FFFF...C04]

25. [OUTIR]
Output the IR data stored in a memory location to one of
the IR outputs to activate the IR emitter and control an
external device.
Command Format: [OUTIRxmmCii]
x = IR output number (n= 1 or 2)
mm = IR memory location number (01 to 99, 2-digits)
ii = Card ID (1-20)
Example:
Output the IR string stored in memory location 2 on IR
output port #1 by sending the following command:
[OUTIR102C04]
This single command reads the entire IR string from
memory and sends it to the IR port. Once the entire
process is complete, the Neutron sends confirmation.
[C04]
26. [WRIRRAM]
Preset the pass-through IR by loading the data into RAM
from the Altinex library directly from the controller. This
command allows virtually unlimited IR commands to be
used in place of, or in addition to, the built-in IR memory of
the Neutron. This command works in conjunction with the
[OUTRAM] command that instructs the controller to output
the data to the IR ports.
Command Format: [WRIRRAMp,dddCii]
p = Saving instructions (1=Overwrite, 0=Append)
ddd = IR data in ASCII characters (100 per command),
Valid characters are "0123456789ABCDEF"
Example:
An IR library command string is 1,000 characters and
requires 10 save commands to save the IR string into
RAM. The following command samples are used to load an
IR string into RAM. Remember to wait for command
acknowledgement from the Neutron after sending each
command before sending the next.
[WRIRRAM1,FFFFF...C04] Overwrite RAM,100 char.

10
A typical installation sets aside a block of 10 memory
locations per device: 01-10 for DVD player #1, 11-20 for
DVD player #2, and 21-30 for TV #1, etc. This makes
applications easier to write and leaves empty memory
locations in the same block for adding features later.
Example:
If the IR emitters are not already installed, prepare a
terminal block with an IR emitter. Connect the test emitter
to the terminal block for IR1 and place the emitter over the
device's IR receiver. This emitter will be used to test each
code as it is learned.
The IR receiver is located on the front of the MultiTasker
enclosure. Prepare the device and its remote control for
normal operation. Know the function you want to learn and
its memory location and send:
[LEARNIR01C04] Learn IR code to memory 01.
BLAST The Neutron displays BLAST when
ready to receive signal. The Neutron
waits up to 7 s to start receiving an IR
signal.
WAIT WAIT is displayed after a signal is
received while it is processed.
[C04] Once received, the Neutron displays
ID as acknowledgement.
[ERC04] If a valid IR signal is not received
within 7 s, the Neutron times out.
[OUTIR101C04] Send the newly learned code to IR1 if
using a test-cable otherwise use the
actual IR port. Verify the device
responds as expected.
28. [IRM2RAM]
Extract IR data stored in an IR memory location and load it
into RAM for faster response time when needed. Use this
command in conjunction with the [OUTRAM] command that
instructs the controller to output the data to the IR ports.
Command Format: [IRM2RAMmmCii]
mm = IR memory location number (01 to 99, 2-digits)
Example:
Load the IR data from memory location 02 into RAM by
sending the following command:
[IRM2RAM02C4]
The entire IR string is read from memory and loaded into
RAM. Once complete, the Neutron sends confirmation.
[C04]
29. [OUTRAM]
Output the IR data previously preloaded in RAM from 1 to 9
times. This command is especially useful for commands
such and volume, brightness, etc. where single step
increments take too long to make large adjustments.

more quickly adjust the volume. The control application is
programmed to send the volume command 3 times every
time the application’s volume UP key is pressed. Output
the volume UP command 3 times to IR output #1 by
sending the following:
[OUTRAM13C04]
The entire IR string is sent in rapid succession to the IR
outputs. Once complete, the Neutron sends confirmation.
[C04]
30. [MODEIR]
Set the IR output modulation frequency to 38 or 56 kHz for
outputs IR1+ and IR2+ independently.
Command Format: [MODEIRnpCii]
n = IR output (n= 1 or 2 for output IR1+ or IR2+)
p = IR frequency (0 = 38 kHz, 1 = 56 kHz)
Example:
Set the IR frequency of IR2 to 38 kHz by sending:
[MODEIR20C04]
Once complete, the Neutron sends confirmation.
[C04]
31. [WRIRFF]
