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).
