CHAPTER 2: Overview
2. Overview
2.1 Introduction
The VGA Extender (AC555A) enables you to transmit VGA signals up to 500 feet
(152.4 m) away with resolution up to 1024 x 768. Common mode noise
suppression circuits provide superb VGA quality via CAT5, 5e, or 6 unshielded
twisted-pair cables.
The extender consists of a local unit and a remote unit. The local unit duplicates
the input signal for local use and transmits the VGA signal to the remote unit.
When the remote unit receives the VGA signal via a CAT5 RJ-45 connector, it
broadcasts the signal to two VGA outputs. A convenient Equalization (gain)
selector switch on the remote unit gives you optimum signal clarity, depending on
the length of the CAT5, 5e, or 6 cable.
You can also order a 4-port local unit and 1-port remote units separately:
• 4-Port Transmitter Only (Local Unit), part number AC555A-4
• Receiver Only (Remote Unit), part number AC555A-REM
The VGA Extender with Audio (AC556A) has all the functions of the AC555A plus
it includes an audio signal.
Both extender pairs are ideal for public broadcasting, exhibits, retail stores,
courtrooms, stock tickers, bus stations, and many other applications.
2.2 Components
The AC556A local and remote units are pictured in Figures 2-1 and 2-2. Tables 2-1
and 2-2 list the descriptions identified by the circled numbers in Figures 2-1 and
2-2.
NOTE
The AC555A has the same components as the AC556A, except for the
audio connectors.
