5. Operation
5.1 Control
The MT319-401 has many advanced remote-control
capabilities accessible through standard TCP/IP or RS232
communication using a computer, control system, or any
device capable of sending commands to the MultiTasker
enclosure.
Additionally, the MT319-401 can be controlled and configured
through TCP/IP communication directly to the AV network
interface on the card’s IP OUT connector.
5.2 Command Organization
The commands in this manual are divided into four sections;
two for the MultiTasker interface (TCP/IP or RS232) and two
via the AV network interface.
MultiTasker Interface Commands
These commands are accessed using the standard
MultiTasker interface. Typically, this is not the same network
interface as the AV network.
1 Common Common to all MultiTasker cards
2 CEC Unique to the MT319-401
AV Network Interface Commands
These commands are accessed using AV network that links
the Homerun (AV over IP) network. This network carries the
encoded video, it should not be a typical LAN used by
employees.
3 UDP UDP commands for the MT319-401
4 Telnet TCP/IP commands for the MT319-401
5.2.1 RS232/TCP Interface
This section lists all the RS232/TCP control and configuration
command formats and their ranges.
The TCP/IP ports have the following default settings:
IP address....192.168.10.84
Port..............23
The rear panel RS232 port has the following settings:
Baud ............115k
Data bits.......8
Stop bits.......1
Parity............None
Flow.............None
5.2.2 Command Basics
The control commands for the MT319-401 are in a simple
ASCII character format.
1. Square brackets "[ ]" are part of the command.
2. Use uppercase letters for all commands.
3. Spaces are NOT legal characters.
4. Do NOT send carriage returns or line feeds;
these are invalid characters.
A command that instructs the card only to perform an action
will generate feedback of "[Card ID]". The open bracket
followed by the card ID and then a close bracket indicates the
card received and executed a valid command. If the command
requested information from the card, the feedback generated
by the card is the acknowledgement of having received a valid
command.
[C04] Card C4 (slot 4) executed a valid command
Invalid commands generate feedback that includes "ER" and
may also include an error code.
[ERC04] Card C4 (slot 4) failed to execute a command
Check command syntax.
Check values sent are within a valid range.
Commands ending in "S" will be saved into memory.
Commands not ending in "S" are executed, but not restored at
reset or power up.

5.2.3 Conventions Used in this Manual
Card IDs:
In this manual, cards are referenced by their card ID which is
equivalent to their slot number:
C1, C2, C3, C4 ... C20
Group IDs:
Groups are referenced by their group ID:
G1, G2, G3 ... G8
5.3 Description of Commands
Each command consists of three parts: Function, Card ID, and
Save.
[ Function , Card ID Save]
Example: [VERC4]
VER = Function
C4 = Card ID or Group ID
S = Save this setting (optional)
The card ID is a unique identifier, equal to the enclosure slot
number. As the slot number, the value can range from 1 to 20
depending on the enclosure.
The group ID is a number representing a group of cards
defined with the [GROUP] command. When using the group
ID, all cards in the group perform the same instruction.
Changing the position of a card significantly affects the
commands recorded on software definitions or third-party
control systems.
Common Commands
1. [C]
This command displays a user formatted status of the card.
Command Format: [Cii]
Example:
Display the status of the MT319-401 card in slot 4 by

CEC Commands
The CEC commands in this section apply to the MT319-402
Rx. They are provided here for reference but have no effect on
the Rx HDMI output when sent to the MT319-401 Tx using the
MultiTasker network (TCP/IP or RS232).
These commands can be sent from the MT319-401 Tx but only
using the AV network interface using the [DB (…)] command
shown later in this manual. CEC commands sent from an
MT319-401 Tx are executed by all Rx units on the same group.
17. [TVx]
This command uses CEC commands to turn the TV
connected to an Rx unit on or off. When sent to a Tx unit
using the AV network command, all Rx units receiving
video from the Tx turn off.
MultiTasker Format: [TVx]
AV Network Format: [DB (TVx)]
x = 1 or 0 (1=on, 0=off)
Example:
Turn off the TV connected to Rx card in slot 4; [TV0C4].
18. [TV1,x]
This command turns on the TV and selects the input
number provided.
MultiTasker Format: [TV1,x]
AV Network Format: [DB (TV1,x)]
x = TV input number (x = 1~9)
Example:
Turn on the TV connected to the Rx card in slot 4 and
switch to Input 2 on the TV by sending [TV1,2C4].
19. [TV1,x,y,z]
This command is a configuration command for Rx units
only and executed when a card reset is executed, [SFT], or
at power up. Configure to turn on the TV and switch to a
known input on the TV. Set the delay time to wait in
seconds and the number of times to try and turn on the TV.
Not all TVs respond to CEC commands when AC power is
first applied. The delay is needed for some TVs to allow a
chance to be ready to accept CEC commands.
MultiTasker Format: [TV1,x,y,z]
AV Network Format: [DB (TV1,x,y,z)]
x = TV input number (x = 1~9)
y = Startup delay in seconds (y = 1~9)
z = Attempts (z = 1~9)
Example:
At power up, turn on the TV connected to the Rx card in
slot 4 and switch to Input 2. Wait 7 seconds before
attempting to turn on the TV. Make 3 attempts to turn on
the TV and switch to Input 2. This is done be sending the
following single command [TV1,2,7,3C4].
20. [TV1,xx,xx,xx,xx]
This command allows a custom CEC command up to 4 hex
bytes. Multiple commands may be sent as needed.
xx = CEC hex code (advanced users only)

UDP Commands
These commands are sent via the AV network, not the
MultiTasker Ethernet or RS232 port.
21. ?Altinex
This is the network identification command. Use this
command to identify all units on a network.
Broadcast to port: 30310
Listen on port: 30311
Command Format: ?Altinex
Example feedback:
[TX,192.168.1.201,255.255.255.0,
192.168.1.0,23,00:11:22:33:44:55,
TP115-401,V01]
[RX,192.168.1.210,255.255.255.0,
192.168.1.0,23,00:AA:BB:33:44:55,
TP115-402,V01]
All TX and RX units report back with their IP address,
TELNET port, MAC address, model number, and virtual ID
(VID). The VID of the TX is always the group number.
22. [IDENTIFY x]
This is a broadcast command that when received, each RX
displays its current IP address and MAC address on
screen. The variable ‘x’ is either a ‘1’ to display or ‘0’ to
remove IP and MAC from on screen.
Broadcast to port 30310.
23. [IxOy]
This is a broadcast command that when received, the RX
unit matching the “y” output switches to display the video
stream that is associated with the “x” input.
Broadcast to port 30310.
Command Format: [IxOy]
x = Group number (TX units)
x = 1~64 play video from source (x is 1 or 2 digits)
x = 0 do not play video, screen off
y = Rx virtual ID (RX units)
y = 1~180 enable network output (y is 1, 2 or 3 digits)
y = 0 to disable Tx network output
If the virtual ID matches the assigned virtual ID, then the Rx
unit changes its group to the value in y.
Example: [I2O1] The Rx with virtual ID 1 sets its
group to 2.
Some special cases:
[IxO*] xis the group.
For example: [I2O*]
All RX units set their group to 2. Any RX that
receives the command with * executes the
command and sets screen on.
[IxO0] xis the group.
For example: [I1O0]
This command is for TX units only, not the
RX. The “O0” (letter O plus zero) tells the TX
unit with the matching group number (1 in
the example) to stop transmitting video.
[I0Oy] yis the virtual ID.
For example: [I0O3]
This command is for RX units only, not the
TX. The “I0” (letter I plus zero) tells the RX
unit with the matching virtual ID (3 in the
example) to stop transmitting video. This is
the same as setting the screen mode to off.

Telnet Commands –AV Network
TELNET connections for control/configuration commands can
only be made on port 23. All commands and feedback are in
the format open bracket ‘[‘ followed by text and end in a close
bracket ‘]’ without carriage returns. The close bracket ‘]’ is the
end of the command.
Each Tx/Rx unit must respond to each command. If a
command requests information, the data is considered the
feedback. All other commands must return either [ ] or [ER]. An
open and close bracket indicates the command was executed
successfully. An [ER] indicates a bad, failed, or unrecognized
command.
24. [SET]
This command is used to configure the Tx unit for use on
the AV network. Each field is separated by a space.
Changes do not take effect until the unit is reset or the
power is cycled.
Command Format: [SET address mask gateway vid]
Address ###.###.###.###
Mask ###.###.###.###
Gateway ###.###.###.###
Group Tx units 1~64
Rx units 1~180
Example:
[SET 192.168.1.110 255.255.0.0 192.168.1.0 01]
Returns [ ] upon execution. After a reset or power cycle, the
unit can be identified as address 192.168.1.110 with group
number 1.
25. [SFT]
This command tells the Tx to execute a soft reset after
which the new IP, mask, and gateway are active. There is
no feedback from this command, it just executes.
Command Format: [SFT]
Example:
[SFT]
This is the equivalent of cycling the power. If network
changes were made using the [SET] command, the new
changes take effect.
26. [Ix]
Rx Only - This command tells the Rx from Tx (group) video
to display.
Command Format: [Ix]
x = Group number (TX units)
x = 1~64 play video from source (x is 1 or 2 digits)
x = 0 is NOT valid, returns [ER]
Example:
Tell the RX to display video from Tx (group) 12.
[I12]
Returns [ ] upon execution.
27. [DB (xx…x)]
Rx Only - This command forwards command data to the Rx
CEC daughter board. The data within parentheses is the
data seen by the daughter board. See the CEC data
section for CEC board internal commands.
Command Format: [DB (xx…x)]
x = CEC board command
[DB (TVx)]......................... TV On/Off
[DB (TV1,x)]......................TV On+Input Select
[DB (TV1,x,y,z)] ................Power up configuration
[DB (TV1,xx,xx,xx,xx)].......Custom CEC command
Example:
Send the following to request the CEC board version:
[DB (VER)]
Example:
Turn off all the TVs that display the video from the
MT319-401 in slot 4 by sending the following:
[DB (TV0)]
28. [DHCP x]
This command enables/disables DHCP mode. If DHCP is
enabled, the network assigns the IP address. By default,
DHCP is disabled. If DHCP is enabled, it is very difficult to
determine which Tx units is which IP. It is best to assign a
fixed IP and disable the DHCP mode.
Command Format: [DHCP x]
x = DHCP mode (0=fixed IP, 1=network assigned)
Example:
Disable DHCP mode by sending the following:
[DHCP 0] returns [ ]
Send the following to read the DHCP setting:
[DHCP] returns [0] or [1]
