Note: The MicroLite Transmitter is typically camera mounted in a standalone application, however
mounting in a more complex rig or housing may be desired per individual requirements. In such cases,
the user should be aware that the MLT is configured via the programmable serial interface. Should you
desire to program the unit while in your application, then you r application design must provide a
means to connect to the serial interface. If your application cannot support a means to connect to the
serial interface, then you must pre-configure the unit prior to installation. Refer to Section 5.
The M
ICRO
L
ITE
TX can be mounted using the four screw holes located on the corners of the housing,
using four #2-56 screws. Tighten the four screws gradually in rotation, without applying excess force
on one before starting the others.
The M
ICRO
L
ITE
TX requires installation using proper thermal dissipation methods. During operation,
energy isdissipated to the outside environment, especially on the lower surface of the M
ICRO
L
ITE
TX.
The bottom surface of the MicroLite TX must be kept at a temperature within the operating
temperature range specified in Chapter 3.
The unit has an internal fan and the fan openings must not be blocked.
The unit should not be operated inside another enclosure unless sufficient cooling is provided that the
case temperature is within the range specified in Chapter 3.

(1) If your system contains a host processor capable of communicating with the M
ICRO
L
ITE
via the
serial interface, use interrogation commands to check the status of the M
ICRO
L
ITE
.
(2) Detect the transmitted signal using a spectrum analyzer.
(3) Using an appropriate receiver, verify that you are receiving audio and video from your
application setup.
5.8 Using the M
ICRO
L
ITE
to Transmit Audio and Video Signals
The M
ICRO
L

uses a COFDM modulation scheme. Receiver systems used with the M
ICRO
L
ITE
must
be compatible and capable of receiving the type of video transport streams transmitted by the
M
ICRO
L
ITE
.
Compatible receivers include the RF Central MicroLite Receiver, the IMT SRx Receiver
and certain other IMT products. Contact IMT for more information.
When no video signal is present, the M
ICRO
L
ITE
enters “Standby Mode.” When a video signal is
present, the M
ICRO
L
ITE
automatically exits “Standby Mode” and resumes transmission. Standby mode
status is indicated on a faceplate user interface LED.
5.9 Using the M
ICRO
L
ITE
To Transmit User Data
The User Data Interface can be used to packetize user data along with the main audio and video
information. The User Data can be received and output by compatible receivers, such as the MLR and
SRx (e.g.). The user data interface must be programmed using the M
ICRO
L
ITE
programmable serial
interface.

Revision 0.2D 33
5.10 Using alternate/custom controllers
The implementation of an RS-232
command set, or Remote Protocol, allows the use of customized
interfaces to perform virtually all unit operations, including:
• Configure Settings
• Query Status
The Remote Protocol consists of command and response messages, or packets. The internal CPU
handles interpretation of the packets to set unit parameters, and provide responses back through the
serial interface.
In addition to IMT’s Nano Controller, alternate control interfaces may be developed, or available from
third parties. Additionally, commands and responses may be entered and viewed manually using a
command terminal.
The Remote Protocol is available upon request from IMT.
5.10.1 Serial Interface Rate, Parity, and Stop Bit Specifications
Refer to the Remote Protocol for information about the baud rate, number of data bits, stop bits, and
flow control methods.
5.10.2 Command and Response Packet Formats
This section provides a brief introduction to the serial interface command and response packet formats.
The command packets use the following format:
NU <tt> <ss><##><cc><dd><CS><CR><LF>
Where the fields are ASCII and are defined as follows:
NU
Literal
<tt>
Address of target (0x01 – 0xFF)
<ss>
Address of source (0x00 – 0xFF)
<##>
Packet Length (Packet Length = Command Length + Data Length)
<cc>
Command (0x00-0xFF) – Different values are used for each command.
<dd>
Data (Hex Format) – Data values are encoded with a variety of meanings.
<CS>
(1’s complement of <tt> to end of data)
<CR>
Carriage Return
<LF>
Line Feed
After a command packet is received, the unit returns a response packet. Response packets have the
same basic format as command packets, except that the source and destination are reversed, and the
command field specifies the type of response being sent.
