
Generate SMPTE-No Genlock to Video
– Generates SMPTE timecode
at the specified Frame Rate based on an internal clock.

Generate SMPTE-Genlock to Video – Generates SMPTE timecode at
the specified Frame Rate based on an external Composite Sync signal.

Read External SMPTE
– Reads SMPTE from an external source and
echoes the incoming SMPTE to the SMPTE Out port.
Enable SMPTE on Power Up
If the SMPTE Machine is configured to generate SMPTE, checking this box will
enable SMPTE generation upon power up. SMPTE timecode will begin at the
Start Time (or Preroll Time , if applicable) given in the SMPTE Generation
Options
.
If the SMPTE Machine is configured to read SMPTE, checking this box will
cause the SMPTE Machine to immediately look for and lock to incoming
SMPTE and begin sending sequence triggers, without requiring a start
command.
Configure Show Control Port

MIDI – You can control the SMPTE Machine’s operation using MIDI show
control messages by checking this button. This configuration may require a
hardware jumper setting change (see the SMPTE Machine Hardware
Reference later in this manual for more information on configuring the unit
for MIDI).

Use MTC – If this option is checked, the SMPTE machine will
generate and decode MIDI Timecode. This option is useful for
converting SMPTE Time to MTC, and vice-versa.

RS-232 – This selection means that port 1 of your SMPTE machine will be
connected to one of the Show Controller’s RS-232 ports.

Enable Timestamp
– If this option is checked, the SMPTE
machine will send a 9-bit message containing the current
HH:MM:SS.FF data out of port 1. An Alcorn McBride Show
Controller can then read this data, and use it for internal timecode
features.
Important: If you wish to use either the MTC or RS-232 Timestamp features,
you will need SMPTE Machine Firmware V1.63 or newer. Also, the Show
Controllers require Firmware V6.42 or greater to decode an RS-232 Timestamp.
SMPTE Generation Options

Preroll Time
– Sometimes when SMPTE will be looping throughout a
show, it is useful to have a SMPTE Preroll of a small length to allow other
show equipment time to lock to the SMPTE signal. When SMPTE loops,
timecode is set back to the Start Time, not the Preroll Time.
