VGA – AUDIO – RS232 EXTENDERS
1. Connect video source to Sender unit using supplied VGA cable. Connect the
RS-232 serial using supplied straight-through DB9 male/female cable. Connect
line-level audio to mini-stereo jack (UV232A only).
Note: The Sender unit receives power from the VGA source
per VESA standard (+5v on pin 9). If the source is not VESA
compliant in that regard, or if the video is YPbPr (using a 3
RCA to HD15 input cable), then a power supply would be
needed at both ends. Two power supplies are included for this
purpose.
2. Connect the Sender's RJ45 port to the Receiver unit using straight-through
UTP or STP cable directly to the receiver. IMPORTANT: You cannot connect
the Cat5 cable to any other manufacturer's device or network equipment.
3. Connect the Receiver to the display device, and use a straight-
through RS-232 cable to connect the receiver to the remote serial
device (e.g. touch-screen (UV232B), projector, etc). Connect audio
output to powered speakers (UV232A only).
Before applying power to the remote unit, 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 extender can tolerate up to
5v peak-to-peak ground potential between the two locations.
Failure to ensure good grounding can result in erratic operation
and possible shock hazards or damage to your equipment.
4. Power receiver using included power supply; check green Power LED on
sender to verify it is receiving power from VGA source. Using a small
screwdriver; turn the compensation potentiometer CW for more compensation or
CCW for less, until the image is perfectly clear.
