2.0 Introduction
The inline camera mount box is an optional housing (for the MDT-B transmitter) which mounts to a professional A/V camera. The housings are designed to use either Anton Bauer or IDX batteries.
The two line LCD (liquid crystal display) provides visual readouts of transmitter frequency, analog video lock status, COFDM mode, COFDM bandwidth, transmitter guard interval, forward error correction (FEC), video input type, audio status, audio gain and backlight status.
In addition the front control buttons allows the most common available options (as described later in this document) to be changed from the front panel. If necessary the transmitter can still be accessed with the use of a PC using GMS control software through the 15-pin DB connector. Refer to MDT-B operation manual (100-M0056, found on GMS web site www.gmsinc.com) for detailed description of the external control software.
3.0 Front Control Panel Operation
The front control panel consists of a two line LCD (liquid crystal display) and four control buttons, the CTRL, ENTR, ↑ (up arrow), and ↓ (down arrow), see figure 1. In general, the up and down arrow buttons are
for selecting available options, the CTRL button is for moving between menus and the ENTR button is for saving new values (as selected with the up and down arrow buttons).
Figure 1 –Front Control Panel
3.1 Menu Structure The overall menu structure is demonstrated as a flowchart in Figure 2. Refer to this figure as the following individual displays are explained in detail.

3.1.1 Power Up
Channel Display
with video
On power up the LCD displays the “GMS” logo and firmware number and then the “Initializing” display appears. It takes approximately 35 seconds before communications is established for the first time on power up.

[Note: If communications cannot be established for some reason the LOST MDT-B COMM display appears. Re-try establishing communications by pressing the ENTR button.]
3.1.2 Main Menu
3.1.2.1 Channel Display The CHANNEL display appears after the front panel establishes communication with the
transmitter . In this mode when the ↑ UP or ↓ DOWN button is pressed the transmitter steps through the available channels. The display blinks for ten seconds after releasing the button. If ENTR button is pressed before ten seconds, the frequency changes and is stored in nonvolatile memory. If ENTR is not pressed before ten seconds, the display will stop blinking and the transmitter will reset to the previous frequency. In addition, on the second line of the LCD the video type and status is displayed. If no video is detected the message “NO VIDEO INPUT” is displayed. Note: This message does not apply when the video input mode is set to SDI .The channel display and control functions are shown below (underline words are meant to demonstrate variables which are subject to change depending on values chosen).

4.1 RF Output The MDT inline camera enclosure uses a female N type connector (flange mount) for its ‘RF Output’ port.
4.2 I/O
The ‘I/O’ connector is a female, DB-15. It is used to provide the interface for RS-232 signals (control and monitoring). GMS MDLB Configurator software program makes use of the RS232 control lines, pins 2, 3 and 5 of the DB-15 connector. The RS-232 channel utilizes a 3-wire configuration. The pin out for I/O connector is shown in Table 2.
A USB connector is currently provided with the external serial cable which is an alternate method of interfacing to the PC if DB-9 connectors are not available.

4.3 Video Input The MDT–B inline camera enclosure uses female BNC connectors for video input. Component, Composite or S-Video input is accepted (see section 3.1.3.5 for setting video input type). J3 BNC connector marked “Y/COMP” is a dual use input connector; a) Composite Video or b) Luminance when used with Component video. J2 BNC connector marked “C/Pr” is a dual use input connector; a) Chroma when used with S-Video or b) Pr, the red component minus the luminance information used with Component Video. J8 BNC connector marked “Pb” is the blue component minus the luminance information used with Component Video.
4.4 Power Switch
An LED indicator rocker switch is provided for controlling power to the unit.
