MEI

Use the MEI protocol setting when controlling the V-R171X-DLW using the Marshall Network Controller box. This protocol allows remote control of all features on the V-R171X-DLW, 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.

MEI-Image Video

This protocol setting accepts Image Video commands via MEI protocol, for use when an Image Video controller is connected to the Marshall Network Controller box.

Tally Source

The V-R171X-DLW OSD tally 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. 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 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/MEI 422

Use the TSL/MEI 422 setting to control OSD tally via the TSL or Marshall serial protocols.

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 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.
