VIDEO CONFIGURATION SUBMENU (continued)  
Pixel-to-Pixel Mode  
Use this setting to enable Pixel-to-Pixel mode.  
This mode bypasses the monitor’s internal scaling function and displays images in their native resolution and aspect  
ratio, with a one-to-one mapping of incoming image pixels to screen pixels:  
For incoming formats smaller than the native resolution of the screen (or selected aspect ratio), the image will be  
displayed in the center of the screen using only the necessary LCD pixels. For example, NTSC or PAL images will  
occupy exactly 720 x 486 or 720 x 576 pixels respectively. The surrounding screen area will be black.  
For incoming formats exceeding the screen resolution (or selected aspect ratio), only the center portion of the  
incoming image will displayed, with the remainder of the picture cropped. For example, 1080i/p formats will both  
be cropped depending on the selected aspect ratio.  
Aspect Ratio Settings  
Use this menu option to switch between several aspect ratio settings  
As the V-R171-IMD-HDSDI monitor has a native resolution of 1680 x 1050 RGB pixels, incoming images are  
automatically scaled to fit the screen:  
In 4:3 mode, images are scaled up or down to fill the maximum 4:3 portion of the screen (1600 x 1200). IMD text  
and time code are superimposed on the lower portion of the image. The audio presence indicator and on-screen  
tally are displayed at the bottom of the screen, outside the image.  
In Scaled 4:3 mode, images are scaled to a smaller 4:3 portion of the screen, leaving space for IMD text, tally,  
and audio presence indicator to be displayed below or around the image. Time code is superimposed on the  
lower portion of the image.  
In 16:9 mode, images are scaled to fill the maximum 16:9 portion at the top of the screen (1920 x 1280). In this  
mode, IMD text and on-screen tally are displayed below the image. Time code and the audio presence indicator  
are superimposed on the lower portion of the image.  
In Full Screen (16:10) mode, images are scaled to fill the entire 16:10 screen (1920 x 1200). In this mode, all  
OSD features are superimposed on the image. Note that when using a 16:9 input image in this mode, the  
image will be slightly vertically stretched.  
The diagrams on the following page show how IMD text, timecode, and the audio monitor icon are simultaneously  
displayed on the screen in each aspect ratio setting. The white area represents the video image.

IMD CONFIGURATION SUBMENU  
Overview  
The V-R171-IMD-HDSDI features an In-Monitor Display (IMD) with the ability to display on-screen text and tally in  
three colors. IMD text, color, and alignment can be assigned to each screen locally using menu options (see below).  
Alternately, IMD text and tally can be remotely controlled via the RS-422/485 serial interface using several industry-  
standard protocols, including TSL and Image Video. Multiple V-R171-IMD-HDSDI monitors can be looped together and  
each addressed individually via the protocol. All menu features of the V-R171-IMD-HDSDI can also be controlled via  
the Marshall Network Controller box and Marshall protocol. (Contact Marshall Electronics for additional information).  
Use the IMD Configuration submenu to configure various IMD parameters as described below.  
IMD Configuration Submenu  
IMD Protocol  
Use the IMD Protocol menu option to choose the protocol with which the V-R171-IMD-HDSDI receives remote  
commands. Currently, four protocols are available. Contact Marshall Electronics for the latest protocol compatibility.  
Image Video  
Use the Image Video protocol setting when controlling the IMD from an Image Video tally controller (e.g. TSI-  
1000) or other controlling device which utilizes the Image Video protocol. The IMD #, IMD Name(S/N), and Baud  
Rate parameters must be set for each screen in conjunction with the controlling device.  
TSL v4.0  
Use the TSL v4.0 protocol setting when controlling the IMD from a TSL tally controller, or other controlling device  
which utilizes the TSL v4.0 protocol. The IMD # must be set for each screen in conjunction with the controlling  
device.  
Marshall  
Use the Marshall protocol setting when controlling the V-R171-IMD-HDSDI using the Marshall Network Controller  
box. This protocol allows remote control of all features on the V-R171-IMD-HDSDI, including marker setup, video  
configuration, system configuration, and image adjustments (brightness, contrast, etc.). The IMD #, IMD Group #,  
and Baud Rate parameters must be set in conjunction with the Network Controller Box.  
Marshall-IV  
This protocol setting accepts Image Video commands via the Marshall protocol, for use when an Image Video  
controller is connected to the Marshall Network Controller box.

On-Screen Menu (continued)  
IMD CONFIGURATION SUBMENU (continued)  
IMD ID #  
The IMD ID # identifies each screen to the controlling device. When using the TSL protocol, the ID # of each screen  
should be manually set in conjunction with the controlling device. When using the Image Video protocol, the ID # may  
be set automatically by the controlling device, after each IMD is initially identified by IMD Name (see “IMD Name[S/N]”  
below). Available ID #s are 000-255. When using the Marshall protocol, available ID #s are 001-254.  
IMD Group #  
Each screen can be assigned an IMD Group # when using the Marshall protocol. Available Group #s are 01-254.  
IMD Name (S/N)  
Use this setting to assign a name to each screen when using the Image Video or Marshall-IV protocols. The IMD name  
is equivalent to the Image Video serial number and is used by the Image Video controlling device to identify  
each screen. The default IMD Name(S/N) is “M00000.” It is recommended to maintain this naming scheme in order to  
avoid serial number conflicts with other Image Video devices on the same serial bus. Each name can be up to 16  
ASCII characters.  
Press ENTER to edit the IMD Name. Use the and buttons to move the cursor. Press ENTER with the cursor on the  
character to be changed and use the and buttons to scroll through character options. Press ENTER to choose a  
character.  
IMD Baud Rate  
Use this setting to choose the baud rate. The baud rate must be set in conjunction with the controlling device. Available  
baud rates are 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200. The TSL v4.0 protocol is fixed at  
38400 bauds.  
IMD Fixed Align  
Use this setting to choose the horizontal alignment of the IMD text. IMD text can be justified on the left, center or right  
of the screen. This setting is overridden when using IMD text via the Image Video protocol (alignment is set via Image  
Video protocol).  
IMD Fixed Color  
Use this setting to choose the color of the IMD Fixed String text (see below). Available colors are red, green, and  
yellow. This setting does not affect text color when using IMD text via the Image Video or TSL v4.0 protocols (text  
color is set via the protocols).  
IMD Fixed String  
Use this setting to display static IMD text on the screen. This setting is used to enter IMD text locally, when a serial  
protocol is not used for remote control. The IMD Fixed String is saved after power cycle. The IMD Fixed String will be  
overridden by serial protocol commands.  
Press ENTER to edit the IMD Fixed String. Use the and buttons to move the cursor. Press ENTER with the cursor  
on the character to be changed and use the and buttons to scroll through character options. Press ENTER to  
choose a character.

Tally Source  
The V-R171-IMD-HDSDI tally (OSD and LED) can be controlled in a variety of different ways. Use the Tally Source  
setting to choose how tally is controlled:  
Standard  
Use the Standard setting to control tally via contact closure on the HD-15 tally interface.  
Image Video HW  
Use the Image Video HW setting to control Image Video tally states via contact closure on the HD-15 tally  
interface. Contact closure of the Red pin corresponds to Image Video Tally 1, and the Green pin maps to Image  
Video Tally 2. Contact closure (ground) corresponds to a LOW state, and open circuit corresponds to a HIGH  
state. This mode requires the IMD Tally Mode parameter to be set. Consult Image Video documentation for  
further information.  
Image Video 422  
Use the Image Video 422 setting to control Image Video tally states via the Image Video serial protocol. LED and  
OSD tally will be disabled in this mode, as Image Video tally states are manifested in the text color and other  
parameters. This mode requires the IMD Tally Mode parameter to be set. Consult Image Video documentation for  
further information.  
Standard + IV422  
Use the Image Video 422 setting to control Image Video tally states via the Image Video serial protocol, while  
controlling LED and OSD tally using contact closure on the HD-15 tally interface. This mode requires the IMD  
Tally Mode parameter to be set. Consult Image Video documentation for further information.  
TSL/Marshall 422  
Use the TSL/Marshall 422 setting to control OSD and LED tally via the TSL or Marshall serial protocols.  
IMD Tally Mode  
Use this setting when using Image Video tally control. Choose one of the following settings, in conjunction with the  
Image Video controlling device. T1, T2, T1T2, T2T1, T1-, T2-, T1T2-, T2T1-. Consult Image Video documentation for  
further information.

Maintenance  
Screen Cleaning  
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-  
fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.  
Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the  
surface. Antistatic and fingerprint resistant cleaning agents are recommended. Do not apply excessive pressure to the  
screen to avoid damaging the LCD.  
Faceplate Dusting  
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,  
attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.
