1. Introduction
1.1 Product Overview
The product is a two-gang, Decora-style wallplate designed to be the primary PC
interface for classrooms, boardrooms, and conference centers. It features DisplayPort
+ Audio to HDMI conversion and an HDMI input. If the DisplayPort signal does not
support embedded audio, the analog audio input port can be accessed via RS232.
The HDBaseT Transmitter utilizes HDBaseT technology to extend the digital output up
to 70 meters away using solid core shielded Category 5e or greater cable. This
transmitter device is compatible with several HDBaseT receivers, but is designed to
work primarily with the HDBaseT Receiver. The unit features multiple EDID modes to
eliminate user confusion, and incompatible video formats.
The HDBaseT Transmitter can be powered from the rear panel or by Power over
HDBaseT (PoH), including midspan injectors that support Power over Ethernet (PoE)
Alternative A or Alternative B. Built-in surge protection and diagnostic LEDs ensure
hassle-free and robust installations. The HDBaseT Transmitter also features a
customizable power management system, which will put the unit into a low power state
after no video for 30 minutes or being inactive for 3 hours by default. When using the
local power input, 12V DC is available for other devices on the power output
connections on the rear of the device.
The HDBaseT Transmitter will detect which input has an active video input, and switch
to that input – if both inputs are active, the “last in” will be selected. RS232 control of
the HDBaseT Transmitter can be accomplished by connecting to the RS232 port on a
compatible receiver, such as a HDBaseT Receiver, or through a direct connection on
the RS232 input of the device.
The HDBaseT Transmitter can be programmed to control the connected display. This
allows display power and input to be automatically controlled based on video activity,
eliminating the need for a third party control system in many installations.

3. Installation Instructions
3.1 Basic Installation
1. Turn off power and disconnection the audio/video equipment by following the
manufacturer’s instructions.
2. Connect shielded Category 5E or greater twisted pair cable with the TIA/EIA-568B
crimp pattern between the transmitter (HDBaseT Transmitter) and the HDBaseT
receiver.
3. If the HDBaseT receiver cannot provide power to the HDBaseT Transmitter,
connect the included power supply to the 12V DC power input of the device.
4. Connect an HDMI cable between the display and the HDBaseT receiver per the
manufacturer’s instructions.
5. Power on attached audio/video devices.
6. Apply power to the HDBaseT receiver.
7. If the HDBaseT receiver cannot provide power to the HDBaseT Transmitter,
connect the power supply going to the HDBaseT Transmitter to an AC outlet.
8. Connect HDMI or DisplayPort/Audio sources. The analog audio input is only
paired with the DisplayPort input. To switch between analog and embedded audio
on the DisplayPort input, please see 5.1.6 DisplayPort Audio.
HDBaseT Cabling Requirements
For all HDBaseT Cabling, the EIA/TIA-568B crimp pattern must be used on
Category 6 or greater cable. In areas with large amounts of electromagnetic (EM) or
radio frequency (RF) interference, a shielded variety of Category 5e or greater cable
is recommended with shielded connectors on both ends of the selected cable.

3.2 Device Power
The HDBaseT Transmitter supports two types of power input: PoH (Power over
HDBaseT) and rear panel input.
When using PoH, a compatible HDBaseT receiver can power the HDBaseT Transmitter
by inserting power onto the twisted pair cable. When using a compatible HDBaseT
receiver, there is no need to use the rear panel power input.
If using a different receiver that does not supply power, you must connect power to the
rear power input. Using this method, the included 12V DC 2A power supply must be
used.
3.3 12V DC Output Power
The HDBaseT Transmitter can provide power to an external 12V DC device that draws
500mA or less of total current. This voltage will be provided if the HDBaseT Transmitter
is powered directly or via PoH.
3.4 RS232 Connections
The HDBaseT Transmitter can be controlled via RS232 by connecting to a computer’s
serial port or third party control system via the connected HDBaseT receiver. The
HDBaseT Transmitter may also be directly controlled via the RS232 port may
communicate directly to the display via RS232 through the HDBaseT receiver.
To u se the R S 23 2 exte n si o n capa b i lit i es of t h e HDBaseT Transmitter, connect the TX,
ground, and RX control signal wires to the removable 4-pole terminal block. Consult the
manual of the control device(s) to determine which pins the TX and RX signals are
carried on. Be sure to always connect TX to RX and RX to TX.
With the built-in Display control functionality, the HDBaseT Transmitter can
automatically turn on and turn off the display when a source is connected or removed
from the device. Please see 4.9 Display Control Functionality.

l 9600 baud.
l 8 Data Bits
l 1 Stop Bit
l Parity=none.
Third Party Device Connections
Below is an example drawing of the 12V DC output and RS232 connections to a
third party device. 22AWG or greater wire is recommended for the power and RS232
connections.

4. General Operation
4.1 Automatic Switching
The HDBaseT Transmitter will switch automatically to the “last in” connected input. For
example, if a DisplayPort signal is currently displayed, and then connect an HDMI
source, the unit will switch to the HDMI input. When the HDMI source is removed, the
unit will switch back to the DisplayPort input.
4.2 RS232 Switching
By connecting the RS232 port of the HDBaseT receiver to a third party control system,
serial commands can perform switching functions, as well as provide greater
information about the units status. RS232 control can be used simultaneously with Auto
operation, but not when using the Display Control functionality.
4.3 LED indicators

4.4 Reset Button
The reset button located under the Status Indicators will reboot the HDBaseT Transmitter.
This may need to be used if in EDID pass-through mode, and the HDBaseT Transmitter
was powered on before the display during installation, which may prevent the EDID from
being read correctly.
4.5 Firmware Port
This port is used for updating firmware. Please contact our after-sales department for
more details.
4.6 EDID Management
An essential part of operations is the EDID table, which is transmitted to the source
from the HDBaseT Transmitter input.
The HDBaseT Transmitter features a pass through EDID mode for the HDMI and
DisplayPort inputs. The preferred native timing of the display will be transmitted to the
source. If the resolution of the TV connected to the output is 1080p, then the switcher
will request the source to output 1080p. The benefit of this method is that the video
output by the source will be formatted perfectly for the display.
In addition to the default EDID pass-through mode, there are many built-in EDID
settings to define the source video output resolution. The built-in EDID tables range
from XGA (1024x768) up to UHD/30 (3840x2160 at 30 Hz). Changing the EDID is
performed via RS232, and the commands can be found on 5.1.10 EDID
Configuration.
4.7 HDCP Management
The HDBaseT Transmitter offers advanced HDCP management to allow greater
compatibility with other devices. The output will always be encrypted or unencrypted,
following the status of the source content. If the content is encrypted, the output of the
HDBaseT receiver will be encrypted; if the content is unencrypted, the output of the
HDBaseT receiver will be unencrypted.
The HDBaseT Transmitter P ships with the HDMI and DisplayPort inputs set to “HDCP
compliant”. This will work for most applications; however, the AS-1H1DP allows you to
set the input to “Not HDCP compliant”. This is important for systems using not-compliant

Scaler WallPlate HDBaseT Transmitter
10
sinks (such as a video conferencing or recording system). To set the unit to “Not HDCP
compliant”, simply connect via RS232 and send the RS232 command as described on
5.1.5 HDCP Compliance.
4.8 Low Power Mode
The HDBaseT Transmitter has a low-power or standby mode that it will automatically
return to, based upon input signal and switching activity.
No Signal
If the HDBaseT Transmitter detects no video on either the HDMI or the DisplayPort input
for a set amount of time, the HDBaseT Transmitter will go into low-power mode. The
default time is 30 minutes, which can be adjusted by sending an RS232 command. The
timeout clock is accurate to +/-4%.
No Activity
If the unit does not switch inputs or communicate via RS232 for a set amount of time, the
HDBaseT Transmitter will go into low-power mode. The default time is 3 hours, which
can be adjusted by sending an RS232 command. The timeout clock is accurate to +/-4%.
Changing Low Power Mode Settings
The No Signal and No Activity timeouts can be changed by sending the unit different
timeout commands via RS232.
If sending RS232 commands, the Turn Display Control OFF command (DFGO)
command needs to be sent first. To disable the timeout, the next two commands to send
to the unit would be Disable the “No Signal” Timeout (DNS000) and Disable the “No
Activity” Timeout (DNA000). These commands are found on 5.1.11 Display Control
Settings.
4.9 Display Control Functionality
The HDBaseT Transmitter may be used to control power and input status of the LCD or
projector connected to an HDBaseT receiver. When the HDBaseT Transmitter is woken
up from low-power mode, it will send the preprogrammed “Power On” commands,
followed by the “Input Select” command. When the HDBaseT Transmitter times out due
to lack of video or activity, it will send the preprogrammed “Power Off” command. This
will effectively synchronize the power states of the display and the HDBaseT Transmitter,
eliminating the need for a third party control system in many installations.

Scaler WallPlate HDBaseT Transmitter

The Display Control functionality may be set up through RS232 commands direct to the
HDBaseT Transmitter or via HDBaseT through a compatible receiver. The HDBaseT
Transmitter can store commands up to 25 characters (25 hex bytes) long.
