LAN
Connect the 491 Encoder to your local network to access web-based
configuration and use network features such as iCap™. The encoder
will be reachable on your network using the static IP address set in the
front panel configuration menu.
GP In & Out
Two blocks of 8 GPI input switches and 8 GPO output notifications.
Switch functions vary based on software configurations. For the default
GPI functionality, see page 39; for the default GPO functionality, see
page 41.
Time Code In
Balanced audio input for LTC time code. The HD495 can also read
VITC data embedded in the master SD video signal; this feature is not
available on the HD491.
Audio In
Balanced audio input for program companion audio in analog, AES
digital format, or embedded audio. If using AES digital audio, an AES
pair of PCM encoded audio at 48kHz should be used. The iCap™
module uses the audio stream selected from the front panel for
encrypted IP transmission to a remote captioner’s iCap™ client. For
more details on iCap™ audio, see the front panel “Audio Setup” menu,
or the HD491 iCap™ Software Manual.
