1. Introduction
1.1 General
The Model AC155A is a Receiver designed to be the counterpart for
the Models AC154A-2 and AC154A-8 Splitters. It converts the CAT5
signals sent from the Splitter back to standard VGA video and audio for
connection to standard VGA monitor and PC speakers.
The device is housed in a compact shielded enclosure and includes a
HD15 connector for the monitor, 3.5mm mini-stereo audio connector
for the speakers, and one RJ45 connector for the CAT5 cable input. A
small power adapter is included with the AC155A.
The AC155A can recover the VGA and audio signals from CAT5 LAN
cables up to 500 feet (152 meters) long with little to no degradation.
The Receiver features a proprietary circuit to compensate for signal
losses in long cable runs.
1.2 Features
•Buffered video and audio outputs
•Supports resolutions up to 1280x1024 at any refresh rate
•User selectable video compensation for receiving on CAT5
cables as long as 500 feet
•Rugged, Reliable, Compact size
•No software required
•Receives audio and video signals on one cable

CAUTION
Before plugging in your remote monitor, verify that the AC line is
properly wired and that a protective ground (green) wire is
established with NO potential difference between both the sender
and Receiver locations (The UTP Splitter can tolerate up to 5 v peak-
to-peak ground noise between the two locations) . Failure to ensure
good grounding can result in erratic operation and possible shock
hazards with severe damage to your equipment. If an LCD is being
used at the remote location, verify that the LCD ground is tied to
power-line ground. If not, then ground the Receiver unit by adding a
ground strap (see troubleshooting section for more information).
NOTICE
Do not connect this unit to any LAN device such as network cards
or hubs as this may damage the AC155A and/or the LAN device. Use
EIA/TIA 568B standard straight-through patch wiring as shown
below. Do not use crossover cables.

3. Configuration & Operation
The only thing that requires configuration on the AC155A is the
COMPENSATION switch setting.
Please refer to Figure 2.2 for the location of the dip switch. The Switch
has two levers. When the lever is down the switch is ON.
Referring to Table 3.1 and set the dip switches according to the cable
length used.
S1/S2 Switch (Up = OFF) Cable Length
OFF/OFF position 0 to 125 feet
ON/OFF position 125 to 225 feet
OFF/ON position 225 to 375 feet
ON/ON position 375 to 500+ feet
The video quality at the remote station depends on the length of the
CAT5 cable, actual video resolution and refresh rate.
