The LEI-589 is a high performance Closed Caption
Decoder for SD SDI system. It is capable of pro­cessing and displaying all standard closed caption
format transmissions. This includes the codes
specified by the FCC Report and Order on General
Docket No. 91-1 and EIA-608 recommended
practices for Captions, Text and XDS.

Nine standard data channels are supported by the
LEI-589: Caption channels 1 through 4 (CC1­CC4), Text modes 1 through 4 (T1 through T4),
and Extended Data Services (XDS). The various
operating modes are selectable from through a
rotary encoder and two push-button switches.

Packaged in LINK's compact 700 Series chassis,
the LEI-589 is both rugged and reliable. If desired,
it may be rack mounted along side two other 500
or 700 Series units of any mix.

Through the “menu” it allows the user to turn off
the open caption black background and display
characters only.

The LEI-589 operates on AC line voltage between
85 to 264 VAC, The front panel has a 8 Charcter
Dot Matrix Display that provides information about
the operating performance. The front panel also
has two push button switches used as Aenter@ and
Aescape@ and a rotary encoder for the selection of
caption information. The Aenter@ switch is used to
select the specific options.

The rotary encoder is used to browse through the
caption or text information. The Aescape@ switch is
used to go back to the previous menu item. The
menu selections may be obtained clockwise or
counter-clockwise on the rotary encoder for ease
of setup.

In addition, the LEI-589 is backed by a standard
10-year wa rranty. High perfor mance, flexibility, and
economy are equally represented in the LEI-589
Open Caption Decoder.
