PCM-3540T/R LVDS Transmitter/Receiver Module

PCM-3540T/R LVDS Transmitter/Receiver Module
Introduction
Traditional LCD configurations are limited in
range from 30 to 50 cm. The PCM-3540T/R is an
ingenious solution to extend the range of LCD
panel monitors. By employing LVDS technology
with transmitting and receiving units, LCDs can
now be placed up to 12 m away from the
computer. The cable connecting the transmitter
to the receiver comes in various lengths: 2 m, 3
m, 5 m, 10 and 12 m.
Some of the advantages to using Advantech's
PCM-3540T/R are: potential 12 m increase in
range of your LCD display, Advantech's
transmitter-cable-receiver combinations exceed
CE and FCC Class A, EMI standards. Furthermore using the PCM-3540T with an Advantech
CPU card/board, equipped with C&T65550 chips,
now supports 36-bit XGA TFT LCD. Please refer
to the Jumper Settings section for detailed
information.
Notes: Advantech has tests show that the
LCD signal can be transmitted up to 12 m
successfully only if using the PCM3540T, PCM-3540R and PCM-10354
(LVDS cable) combinations. For better
image quality be sure the LCD is
grounded firmly.

• Standard PC/104 form factor for PCM-3540T
• Supports 18-bit, 24-bit, 36-bit and 48-bit
resolutions up to 1024 × 768 TFT LCD

WARNING!
Discharge your body’s static
electric charge by touching the
back of the grounded chassis of
the system unit (metal) before
handling the board. You should
avoid contact with materials that
hold a static charge such as
plastic, vinyl, and styrofoam.
The board should be handled
only by its edges to avoid static
damage to its integrated circuits.
Avoid touching the exposed
circuit connectors.

Setting Jumpers
PCM-3540T Jumper Settings
You configure the board to match the needs of
your application by setting jumpers. A jumper is the
simplest kind of electric switch. It consists of two
metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to
connect them. To “close” a jumper you connect the
pins with the clip. To “open” a jumper you remove
the clip. Sometimes a jumper will have three pins,
labeled 1, 2, and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

Cable power enable/disable: JP4
Panel type selection: JP2 Pin 1-2
This function allows the PCM-3540T to provide
power (+5V DC) to the PCM-3540R via the LVDS
cable. If you set JP4 as "enable", you should also
set JP1 on PCM-3540R as "Power from LVDS
cable". It's not recommended to set JP4 as "enable"
if the LVDS cable is equal to or longer that 5
meters.
