• Outputs MIDI Time Code (MTC) to the host. Whenever the <strong>BiPort</strong> is<br />
reading or writing SMPTE it will convert the SMPTE information to<br />
MTC. This MTC is transmitted to the host computer via the host serial<br />
cable.<br />
• Monitors the host port for SYSEX control information. This is where<br />
commands from the Remote Control software are received.<br />
Functions Shared by Both Modes<br />
Most <strong>BiPort</strong> functions are available in both MIDI Interface and Stand-<br />
Alone modes. This section describes the operation of each of these<br />
“common” functions.<br />
SMPTE Writer<br />
The SMPTE Writer generates continuous SMPTE and MIDI Time Code.<br />
While writing SMPTE, the “Writing” LED is always illuminated. The<br />
writer may be configured, started and stopped either manually (see<br />
“Write” Button section) or via software. The writer configuration<br />
includes SMPTE output format, start offset, and User Bits. The poweron<br />
defaults for these parameters are 30 fps, 01:00:00:00, and 00 00 00 00,<br />
respectively.<br />
Important: Powering down the <strong>BiPort</strong> 2x4s will reset all<br />
internally-stored values to their factory defaults.<br />
When the SMPTE Writer is running, the SMPTE reader is disabled. In<br />
fact, the SMPTE writer may override the SMPTE Reader at any time.<br />
While the writer is running, the front panel “Format” button is also disabled.<br />
The writer must be stopped before the output format may be<br />
changed.<br />
The Writer is capable of generating SMPTE in five formats: 24fps, 25fps,<br />
29.97fps, 30 drop-frame and 30 non-drop. The 29.97fps format is only<br />
accessible via the Remote Control Software. It is displayed on the front<br />
panel “Format” LEDs as 30fps.<br />
SMPTE Reader<br />
The SMPTE Reader locks to incoming time code, regenerates it to<br />
SMPTE Out (regeneration occurs only in Stand-Alone mode), and converts<br />
it to outgoing MIDI Time Code. The SMPTE Reader is capable of<br />
automatically detecting the incoming SMPTE format. When it does, it<br />
