Genesis™ Matrix Switches
1.0 General
The Genesis™ series refers to compact, high-end matrix switches for video and
audio. The matrices are used for cross-point switching of video and audio signals.
The switch provides 8 or 16 video (and audio) outputs, each capable of
independently displaying any of 8 or 16 inputs in any combination. Additionally,
the outputs can be blanked out and/or muted. Genesis™ matrices can be used in
TV broadcasting environments, multi-media conference halls, public facilities,
large display projects, schools, courtrooms, and command & control centers.
The units are compatible with PC video from 640x480 to 1920x1600 or analog
SD/HDTV Component Video (YPbPr) from 480i to 1080p.
The Matrix can be controlled in 3 ways: manually using the buttons on the front
panel, through one or two serial RS232 control ports, or remotely via IP port.

2.0 Installation
The matrix is housed in a 2RU 19” wide rack mountable enclosure. All of I/O,
control, and the power connections are on the rear of the unit.
Figure 1 – Rear panel of the standard matrix showing all the connections
2.1 Input Audio & Video Connections
Below the input connections are described first for standard units (those with
HD15 connectors) and then for units having RJ45 inputs. Please keep in mind that
some of the following information may not apply to every matrix switch.
2.1.1 AV inputs on standard unit
Figure 2 - Audio and video inputs on Standard 16x16 unit
2.1.1.1 Video inputs
The video connectors on the basic unit are HD15 female. These are compatible
with PC’s VGA video signal (RGBHV). The Matrix is also compatible with
analog SD or HDTV video (YPbPr) with resolutions from 480i to 1080p. To
connect these types of signals to the matrix, HD15 to 3-RCA cables may be
required.

Genesis™ Matrix Switches
Technical Note about the Video Inputs
The HD15 inputs of the matrix handle only the color and sync signals.
EDID (extended display identification data) is absent. EDID is normally
used by the source PC to read pertinent information from the
connected display. This information includes a list of the resolutions
that are supported by the LCD. If EDID is not implemented, the source
PC is unaware of the specific LCD connected to it. Generally this is not
a problem since in the absence of EDID; most PC’s allow the user to
select from a set of default resolutions for output. Some PC’s may not
output any video signal, or only allow limited resolution settings with
the absence of EDID. One way to resolve this is to change the display
settings of the PC to show all modes and not detect Plug and Play
LCD. The procedure for doing this varies depending on the operating
system and the video card in the PC. It is generally found under:
Control Panel > Display Settings > Advanced > Monitor tab.
An alternative method is a hardware solution which does not require
any changes to the PC’s display settings. Hall Research manufactures
EDID Emulators that are constructed as simple HD15 pass-through
adapters. Inside, they emulate an LCD’s EDID supporting a wide range
of 4x3 and 16x9 PC resolutions.
Figure 3 – Pass-Thru EDID
Emulator
Model: EM-EDID-HD15
You would simply plug one of these at your video source or input to the
matrix.
2.1.1.2 Audio inputs
The audio input on the basic unit uses standard 3.5mm mini-stereo connectors. To
use these with PC audio, standard male-to-male audio extension cables would be
required. To connect from typical TV sources with separate right and left
connectors, 3.5mm male to 2 RCA cables would be needed.
For mono audio, then the tip of the 3.5mm connector (tip = left channel) should
be used.

Hall Research Technologies, Inc.
Technical Note about the Audio Inputs
Since the audio inputs are unbalanced (single ended), the ground
reference of the source has to be the same as the matrix. Of course
the cable connecting the two is tying the grounds across but if there
are currents flowing in the ground it can create potential differences
that would manifest as noise. The quality of grounding at the audio
source and the matrix are important. For example if the input source is
a desktop PC, as long as the PC is properly grounded and the audio
cable length is not excessive, you can expect good results. On the
other hand if the input is a notebook PC running on battery, there is no
ground reference at the source so it gets its reference through the
audio (and video) cable connection to the matrix. This should also be
okay. However if it is plugged in through its external power brick, noise
can be induced. This is because most notebook power supplies do not
properly provide an AC ground path to the system ground (some only
have only 2 prong AC cords). The switching power supply circuit will
inject noise into the audio lines. In this case the solution may be to
attach a low resistance ground strap to the notebook. The other option
for eliminating the noise is to use a stereo audio Balun (or isolator).
The Balun essentially couples the audio through a transformer so the
audio grounds are isolated. Baluns can also cure noise pickup in long
cable runs.
2.1.2 AV inputs on units with RJ45
Two types of RJ45 input configurations may be possible. Please contact Hall
Research sales for availability and delivery information. The model number
designates the input either as:
JP (RJ45 with power) or
JA (RJ45 with Audio).
2.1.2.1 RJ45 input with Video and Power
The JP units are compatible with Hall Research’s Mini-Cat® series of senders.
The Matrix can also send power to one channel senders via the CAT5 cable so
that no external power supply would be needed. This is applicable to senders
with only 1 RJ45 output as listed in the following table.

and then for those with RJ45 outputs.
Figure 4 – Standard matrix audio and video outputs

11
Genesis™ Matrix Switches
2.2.1 AV outputs on standard unit
The video output connectors on the basic unit are HD15 female. These are
compatible with PC’s VGA video signal (RGBHV). The Matrix is also
compatible with YPbPr HDTV signals with the use of HD15 to 3 RCA adapter
cables.
The audio outputs of the matrix are balanced. So a + and a – are provided for each
side. There is also a ground connection available. If you are going to connect the
matrix output to a single-ended audio device (one with RCA or phono
connectors); then use the + of the left, + of the right, and ground. On the other
hand, if you will be connecting the output to professional audio gear it is best to
use the differential + and – (balanced) outputs of each side that offer immunity to
noise.
Figure 5 – Typical balanced audio output connector
The balanced audio outputs are provided on detachable screw-terminals. Mating
connectors for all outputs are also provided.
Technical Note about Professional Audio Output
Matrices with Pro Audio option can individually adjust the audio levels
at each input. Additionally they can set all the outputs to “pro line-level”
of +4bBu. This is a global setting which boosts all the outputs to a high
line level.
2.2.2 AV outputs on units with RJ45
Currently there are three types of RJ45 output configurations possible. Please
contact Hall Research sales for availability and delivery information. The model
number designates the outputs either as:
JP (video on RJ45 with power)
JA (video on RJ45 with Audio)
JR (video on RJ45 with RS-232 Serial)
Other RJ45 output configurations will be forthcoming (such as JRA video, audio,
and serial).

and Audio outputs
Acts as a combination URA & 2-channel A/V splitter.
Note about Screw-Terminal Audio Outputs on units with RJ45
If the matrix has the audio switching feature, then the balanced audio
outputs are always active even if the RJ45 outputs have audio (JA
output option). It is important to note that the channel number for the
audio output is the same. So RJ45 output #1 has the same audio as
screw-terminal audio output #1.
2.2.2.3 J45 output with Video and RS232 Serial (JR)
The JR units are compatible with Hall Research’s UR232 series of receivers for
unidirectional (send only) RS-232 communications. For bidirectional
communications, please contact Hall Research sales for the compatible receiver.
Currently available compatible receivers are listed in the following table.
Technical Note about Video + RS232 Outputs
The matrices with JR output option are capable of sending and
receiving RS232 data independently at each of the RJ45 outputs with
the video on the same Cat5 cable. The output channel number and
baud rate are dynamically set by the user (via serial or IP control port).
The matrix then sends user’s command at the specified baud rate to
the designated output and buffers any response from the selected end-
point for the user to read back. This is described in further detail later in
this manual.
2.3 Power input connection
The matrix has a built-in universal power supply. The AC input connector on the
rear of the matrix is an IEC320/C6 and is always shipped with a North American
power cord (shown below). Users in countries with different plug type should

14
Hall Research Technologies, Inc.
purchase a compatible power cord or use an adapter. The Matrix supports both
110 V, 60 Hz and 220 V, 50 Hz power systems. There is a power on indicator
light on the front panel
Figure 7 –IEC320 / C6 power cord
2.4 Control Inputs
The matrix can be controlled from either RS-232 or through IP.
2.4.1 Basic Unit with RS-232 Control (no IP)
The basic system without IP feature actually has 2 separate and independent RS-
232 control ports.
The main RS-232 port is on a screw terminal and the auxiliary port is on an RJ45.
Caution on RJ45 Control Input
Both matrices with IP control and those without have an RJ45
connector next to the RS-232 screw terminal.
This RJ45 connector is a 10/100 Base-T Ethernet for the matrix with
IP, or a secondary RS-232 Serial control port for those matrices
without IP feature. It is easy to confuse their function.
A sure way to tell if the RJ45 control input is LAN or Serial is by the
presence of little LED indicators to the sides of the connector. If the
connector has these lights, then it is a LAN connection, otherwise it is
an RS-232 serial connection.
Figure 8 – IP input versus Auxiliary RS-232

15
Genesis™ Matrix Switches
2.4.1.1 Primary RS-232 Control Port
This is a 3-terminal captive screw input. A detachable mating connector is
provided. The function of each pin is designated on the panel above the
connector. Below is a diagram for connection this port to a PC’s DB9 serial port.
Figure 9 – Primary RS-232 to PC cable
2.4.1.2 Auxiliary RS-232 Control Port
The matrix switches without IP control have a secondary serial port that can work
independently of the primary port. The user can control the matrix from either or
both ports.
The auxiliary RS-232 connector is an RJ45. Make sure to not connect this to any
LAN devices. The pinout for the auxiliary RS-232 follows the basic EIA-561 for
TX RX and Ground. Optional current limited 12v DC may also be provided (max
rated output current of 50 maDC) that can be used to power external keypads or
control devices, please contact Hall Research if you need to draw power from this
connector.
Caution High-Voltage
Never open the unit’s cover. Lethal voltages exists inside the unit
Opening the unit also voids the warranty on the unit.
The pinout is shown below.
Figure 10 – Aux RS-232 port pinout

16
Hall Research Technologies, Inc.
2.4.2 Units with IP control
Matrices with the letter ‘I’ in the control block of the part number are equipped
with 10/100 base-T Ethernet connection and can be controlled via IP. They also
have the primary RS-232 serial control port on the screw terminal input. The
command set for controlling the matrix via the IP port is exactly the same as the
RS-232 port. The basic method of control is via Telnet. Please see section entitled
“IP Control Basics” for further details.
3.0 Operation
The Genesis™ Matrices can be operated using the front panel buttons, by serial
commands via RS232, or through the IP port.
3.1 Front-Panel Buttons and Indicators
An image of the front panel for the 16x16 matrix is shown below. The 8x8 units
have fewer INPUT and OUTPUT buttons than shown in this picture.
Figure 11 –VSM-16-16 front panel controls & indicators
The front panel can be used for the following purposes:
•Monitor Power On/Off status
•View current routings (ties) either from input or from output
•Make new ties either from input or from output
•Blank or mute a particular or all outputs
•Recall preset patterns
•Save preset patterns
•Disconnect all ties
•Adjust volume (gain level) of each input’s audio for Pro versions
•Display current sound level as a digital light bar VU meter
•Set the output audio to high line level (of +4dBu) on Pro units
•Recall factory presets

17
Genesis™ Matrix Switches
All of the front panel switches have built-in LEDs that help in the operation. The
functions of front panel are carefully designed for intuitiveness. With just a little
practice, one can learn to quickly monitor and control the matrix.
3.1.1 Viewing Audio and Video Routings or “Ties”
There are three different ways to view a tie: Video & Audio, Video only, or
Audio only. The point of view can also be either from input side (where the
selected input is routed to), or from the output side (see which input is feeding the
selected output). You can also use the ▲and ▼buttons to quickly go through
and check status of all channels. Furthermore, during viewing of ties you can
make new ties.
3.1.1.1 Viewing ties by Video and Audio
Press and release both VID and AUD buttons so that the LEDs of the VID and
AUD buttons are lit, which indicates that you are going to view both together.
At this point you have to decide if you want to view from the point of view of the
input or the output side.
… To View from input side
Press and release any Input button, the backlit LED of that button will light, and
all the backlit LEDs for the outputs whose video and audio are both currently tied
to this input will also light up solid.
Note
If there is audio breakaway, the output LED will not be lit. An example
may be that output #2 video is tied to input #7 while output #2 audio is
tied to input 12. In this case if you start the viewing from input #7,
output #2 will not be lit even though input 7 video is routed to it. To see
video ties independently from audio ties, only the Video or the Audio
LED on the front panel should be lit, not both.
You can now use the ▲and ▼buttons to quickly go through all inputs.
You can also make new ties by hitting output buttons. New ties will not take
effect unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.

18
Hall Research Technologies, Inc.
… To View from output side
Press and release any output button, the backlit LED of that button will light, and
if that output’s video and audio are tied to one particular input, that input LED
will also light.
Note:If there is audio breakaway, the input LED will not be lit
You can now use the ▲and ▼buttons to quickly go through all outputs.
You can also make new ties by hitting another input button. New ties will not take
effect unless ENTER is hit (see next section).
When you are done viewing ties, to exit you can hit ENTER. If you don’t hit any
buttons, then after 8 sec the view function times out and all the input and output
LEDs will go out.
3.1.1.2 Viewing ties by Video only
Press and release the AUD and/or VID buttons so that the backlit LED of the VID
button is lit and the AUD button is off
At this point you have to decide if you want to view from the point of view of the
input side or the output side.
… To View from input side
Press and release any Input button, the backlit LED of that button will light, and
all the backlit LEDs for the outputs whose video is currently tied to this input will
also light up solid.
You can now use the ▲and ▼buttons to quickly go through all inputs.
You can also make new ties by hitting output buttons. New ties will not take
