Operating instructions

21
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.
MEI
Use the MEI protocol setting when controlling the QV171X-HDSDI using the Marshall Network Controller
box. This protocol allows remote control of all features on the QV171X-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.
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 QV171X-HDSDI 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, 1700, 4800, 9600, 19200, 38400, 57600, 115200. The TSL v4.0
protocol is fixed at 38400 bauds.
