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.

CHAPTER 3: Installation
3. Installation
You’ll need one local and one remote unit (AC555A includes a 1-port local unit and a 1-port remote unit). You can also order a 4-port local unit (AC555A-4) and
1-port remote units (AC555A-REM) separately. You’ll also need a VGA source such as a PC (not included), Category 5, 5e, or 6 cable (not included), and power supplies (one for each unit, included). Follow the steps listed on the next page and refer to Figures 2-1, 2-2, and 3-1 as you install the extenders.
The AC556A accepts one stereo signal (the left and right channels) input on an audio jack (similar to a computer). The stereo signal is broadcast to the two local audio outputs and is “mixed” together to form a mono signal before transmitting to a remote unit via CAT5, 5e, or 6 cable. Therefore, the left channel and the right channel audio signals at a remote unit are the same.
After all connections are secure, you may plug the power adapters into the local and remote units’ power receptacles; then plug the power adapters into AC outlets.

3.1 Local Unit Connections
1. Make sure that all devices that you will connect to the extenders are powered off.
NOTE
If you are unsure of what type of cable or cable length to use, call
Technical Support at 724-746-5500.
2. Using the included VGA cable, connect the local unit’s HD15 input connector (labeled
❸ in Figure 2-1) to the VGA source (for example, a PC).
3. Using the monitors’ cables, connect two output monitors to the local unit’s
HD15 output connectors (labeled
❻ in Figure 2-1).

CHAPTER 3: Installation
4. Using audio cable, connect the local unit’s audio input connector (labeled
❹ in Figure 2-1) to the VGA source’s audio connector. (This step does not apply to the AC555A and AC555A-4; they do not support audio connections.)
5. Connect the local unit’s two audio output connectors (labeled
❺ in Figure
2-1) to two sets of speakers. (This step does not apply to the AC555A and
AC555A-4; they do not support audio connections.)
3.2 Remote Unit Connections
6. Using the monitors’ cables, connect two output monitors to the remote unit’s
7. Connect the remote unit’s audio output connectors (labeled
❿ in Figure 2-2) to the VGA source’s audio connectors. (This step does not apply to the
AC555A and AC555A-REM; they do not support audio connections.)
3.3 Connecting the Local Unit to the Remote Unit
8. Using Category 5, 5e, or 6 cable, connect the local unit’s CAT5 output port
(labeled
❷ in Figure 2-1) to the remote unit’s CAT5 input port (labeled
❽ in
Figure 2-2).
9. Connect each unit’s power supply to its power supply connector (the local power connector is labeled
❶ in Figure 2-1, and the remote power connector is labeled
❼ in Figure 2-2).
10. Power on the local and remote units.

4. Operation
Once the VGA Extender is installed, monitor the extender’s operation via its LEDs.
Also, use the equalizer selector switch to adjust the VGA signal for various cable lengths and characteristics.
4.1 LEDs
There are two LEDs on each unit. On the local unit, the Power LED lights when proper power is supplied to the unit. The Active LED lights when the extender detects a VGA input signal.
On the remote unit, the Power LED lights when the unit is properly powered. The
Active LED lights when the extender properly decodes VGA signals for the two local HD15 VGA ports. If the AC556A is used to transmit audio signals only, the
Active LED never turns on.
4.2 Equalizer Selector Switch
Adjust the equalizer selector switch on the remote unit (labeled
❾ in Figure 2-2) for optimum video signals for various cable lengths. Choose from the four lengths listed in Table 4-1.
Table 4-1. Equalizer selector switch settings.

APPENDIX: Troubleshooting
Appendix. Troubleshooting
A.1 Problems/Solutions
Problem: No VGA signals are received at the remote unit.
Solution: Make sure that both the local and remote units are powered on. The
Active LED will light on both units to indicate that the signal is correct.
Problem: The VGA signal is garbled.
Solution: Make sure that the wires inside the cable conform to the straight-pinned
EIA/TIA 568A or 568B standard.
Problem: The Active LED on the remote unit is always off.
Solution: The Active LED on the local unit must be on. Check the CAT5, 5e, or 6 cable wiring. Make sure that the Power LED on the remote unit is on.
Problem: The VGA quality changes when you change cables.
Solution: Use the equalizer selector switch to adjust the VGA signal for various cable lengths and characteristics.
Problem: There’s no audio signal at the remote unit.
Solution: Make sure that the volume is high enough.
