<strong>BiPort</strong> performs the following functions:<br />

• Acts as a SMPTE writer. The user may manually configure, start and<br />

stop the SMPTE writer from the <strong>BiPort</strong>’s front panel. The SMPTE signal<br />

appears at the SMPTE Out jack.<br />

• Acts as a SMPTE reader/regenerator. If the <strong>BiPort</strong> is not writing<br />

SMPTE, whenever a valid SMPTE signal appears at the <strong>BiPort</strong>’s<br />

SMPTE In, the <strong>BiPort</strong> will synchronize with and read the incoming<br />

SMPTE signal. It will also automatically regenerate SMPTE to the<br />

SMPTE Out jack.<br />

• Outputs MIDI Time Code (MTC) on MIDI Out-A. Whenever the<br />

<strong>BiPort</strong> is reading or writing SMPTE it will convert the SMPTE information<br />

to MTC. The MTC will exit the <strong>BiPort</strong> at MIDI Out-A.<br />

• Monitors MIDI In-A for SYSEX information from an external source.<br />

An external MIDI device may use SYSEX commands to configure,<br />

start and stop the SMPTE writer.<br />

• Acts as a “thru box” for Mac printer or modem operation.<br />

• All front panel buttons are active in this mode. Only MIDI ports In-A<br />

and Out-A are active.<br />

MIDI Interface Mode<br />

When connected to a PC or Mac host computer, the <strong>BiPort</strong> may be commanded<br />

into Interface Mode by that host computer by launching a MIDI<br />

application that utilizes the <strong>BiPort</strong> driver. When it does, it will indicate<br />

the host type by lighting either the “MAC” or “PC” LED on the <strong>BiPort</strong><br />

front panel (these will light in Stand-Alone mode when accessing the<br />

Remote Control software). As an interface, the <strong>BiPort</strong> 2x4s acts very similar<br />

to the Midiman Portman 4x4/S TM and other MIDI/SMPTE interfaces.<br />

In MIDI Interface mode, the <strong>BiPort</strong> performs the following functions:<br />

• Acts as a 2-input 4-output MIDI interface. Data is routed between<br />

the host and all MIDI ports simultaneously. Each port is capable of<br />

independent 16-channel MIDI operation.<br />

• Acts as a SMPTE writer. The SMPTE writer may be configured, started<br />

and stopped by either the front panel controls or by Remote<br />

Control software. The SMPTE signal appears at the SMPTE Out jack.<br />

• Acts as a SMPTE reader. Similar to Stand-Alone mode, the <strong>BiPort</strong><br />

monitors incoming signals at the SMPTE In jack and locks to it whenever<br />

valid code is detected.<br />

IMPORTANT: In order to guarantee full MIDI bandwidth on<br />

all ports and accurate SMPTE regeneration, Interface Mode<br />

does not regenerate incoming SMPTE. Only Stand-Alone<br />

Mode regenerates SMPTE.<br />
