5. Operation
5.1 Control
The MT318-101 has many advanced remote-control
capabilities when used in the MultiTasker enclosure. These
capabilities are accessible through standard RS232 or TCP/IP
communication. The actual controlling can be accomplished
through a computer control system or any other device capable
of sending commands.
5.1.1 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
5.1.2 Command Basics
The control commands for the MT318-101 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.
5.1.3 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
5.2 Description of Commands
A command consists of 3 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
software definitions or third-party control systems.

the current settings.
[19200,N,8,1C04]
18. [TRRS]
Send a string of data through one of the HDBT Tx ports
and enable the receive option on the same port. The data
sent using this command is output on the RS232 port of the
Rx (UT260-104) connected via the HDBT port.
Use this command when data from the device is expected
by the control application. This command may be used with
the [..S] option to set the startup state of the receive option.
Command Format: [TRRSn=dd…dCii]
[TRRSn=dd…dCiiS] Send & save
n = Port number (1 or 2)
ddd = data to be transmitted (keyboard characters)
Use % for HEX value (ex: %0D=carriage return)
Send no data to simply enable the Rx port. For
example, send [TRRS1=C04] to enable the
receive option on the card port.
Example:
Output “[VER]” on the RS-232 port of the Rx
connected to HDBT port #1 by sending the
following to the controller:
[TRRS1=%5BVER%5DC04]
Feedback from the Rx is received by the
MultiTasker in the form of (RSndd…dC04). See
the (RS) command for details.
19. [TRTX]
Send a string of data through one of the RS232 ports and
disable the receive option on the same port. The data sent
using this command is output on the RS232 port of the Rx
(UT260-104) connected via the HDBT port.
Optimize system performance using this command when
data from the device is not used by the control application.
Excess data from external devices uses card processor
time as well as enclosure bus resources. In severe cases,
overall MultiTasker performance may be affected.
Command Format: [TRTXn=dddCii]
[TRTXn=dd…dCiiS] Send & save
n = Port number (1 or 2)
ddd = data to be transmitted (keyboard characters)
Use % for HEX value (ex: %0D=carriage return)
Send no data to simply disable the Rx port. For
example, send [TRTX1=C04] to disable the
receive option on a card port.
Example:
Output “[VER]” on RS-232 port #1 by sending the
following to the controller:
[TRRS1=%5BVER%5DC04]

20. (RS)
This is unsolicited feedback. The RS232 data received by
the MT318-101 from the Rx is sent to the MultiTasker
control when received on either port. The data is not
analyzed; it is simply relayed to the MultiTasker, in one or
more groups depending on how the data is received.
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 MT318-101 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 MT318-101 port 1 is connected to an HDBT Rx. 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.
(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)
