Installation
Getting Started
Before installing your LongView Wireless extender, refer to the list below to ensure that you have
all items that shipped with the product.
Supplied with the LongView Wireless extender
• LongView Wireless transmitter
• LongView Wireless receiver
• Two local country power supplies
• Audio cable
• LongView Wireless Installer/User Guide
• LongView Wireless Quick Installation Guide
Before you Begin: A Note on Maximizing Your Wireless Range
The number, thickness and location of walls, ceilings and other objects that the LongView Wireless
signals must pass through may limit the range. Typical ranges vary depending on the types of
materials and background RF (radio frequency) noises in your home or business.
To maximize your wireless range:
1. Keep the number of walls and ceilings between the transmitter and receiver to a minimum;
each wall or ceiling can reduce your wireless product’s range.
2. Position a direct line between your transmitter and receiver so that the signal will travel
straight through a wall or ceiling. A wall that is 1.5 feet thick (.5 meters) at a 45°angle appears
to be almost 3 feet (1 meter) thick; at a 2°angle, it looks over 42 feet (14 meters) thick!
3. Position your wireless devices and servers with wireless adaptors so that the signal passes
through drywall or open doorways and not other materials. Building materials such as a solid
metal door or aluminum studs can impede the wireless signal and may have a negative effect
on the wireless range.
4. Keep your LongView Wireless transmitter and receiver away (at least 3 to 6 feet or 1 to 2
meters) from electrical devices or appliances that generate extreme RF noise.

is established, mouse, keyboard, video and audio data are free to flow between the two devices.
To power up the LongView Wireless extender:
1. Complete all of the installation steps. See Chapter 2.
2. Power up the LongView Wireless transmitter and wait for the middle LED labeled S2
to illuminate.
3. Power up the monitor attached to the LongView Wireless receiver.
4. Power up the LongView Wireless receiver.
5. Power up your server.
NOTE: Always power up the LongView Wireless transmitter and wait for the middle LED labeled S2 to illuminate
before powering up your server.
Informational Messages
When the LongView Wireless receiver is powered up, it will display a message on the server
monitor to which it is attached:
Searching for CLT_000c4116bc7b
The 000c4116bc7b is replaced by the MAC ID of the radio board in your transmitter device. This
message indicates that your receiver device is actively searching for its companion transmitter.
When it finds the companion transmitter, it will display a second message beneath the first.
Connecting to CLT_000c4116bc7b
The 000c4116bc7b is replaced by the MAC ID of the radio board in your transmitter device. This
message indicates that your receiver device is establishing the radio link with your transmitter
device. When this link is established, both messages will be removed and the monitor will display

LEDs
Both the LongView Wireless transmitter and receiver contain three LEDs visible from the front of
each device. These LEDs display the current state of each device. Table 3.1 outlines
each condition.
Figure 3.1: Transmitter LEDs
Fine-tuning the image settings
Once the radio link has been established, the receiver will dynamically adjust the video parameters
to optimize the video display. This adjustment will be performed each time the receiver is powered
or if it detects a change in video resolution.
If additional fine-tuning of the video settings is desired, the OSD utilizes an Auto Setup feature to
adjust the image settings. This feature is the same as the dynamic adjustment, but accessed by
selecting the Run button from the OSD Main menu.
The OSD Advanced menu allows for the manual adjustment of individual image settings. These
new settings may be temporarily or permanently saved. If settings are temporarily saved (by
selecting the Cancel button) they will remain active until the LongView Wireless receiver power is
recycled or if a change in video resolution is detected.
Fine-Tuning System Reception
Using the link station indictor on the OSD, adjust transmitter and/or reciever postions to obtain
maximum signal strength. The more green bars, the better the signal strength and performance.
