Switching
The CS-88MHDBTS and CS-44MHDBTS can be switched from the front panel by selecting the OUTPUT button first and
then selecting the INPUT button:
1. Press the OUTPUT button (1 through 8) on the bottom row that corresponds with the OUTPUT (Display, or Sink
Device) you would like to send to a source.
2. Once pressed, the switch will illuminate the OUTPUT button that you have selected, along with the INPUT row,
indicating that it is ready for you to select the INPUT.
3. Select the desired INPUT.
EDID
The CS-88MHDBTS and CS-44MHDBTS has the ability to control the EDID that the source devices sees as a display
1. Press and hold the INPUT button of the source you want to set EDID for 3 seconds
2. Use the selected INPUT button as UP and the corresponding OUTPUT button as DOWN to select the desired
EDID setting
3. To set the selected EDID setting press and hold for 3 seconds the original INPUT button
Toggle DHCP
The CS-88MHDBTS and CS-44MHDBTS comes from the factory with DHCP turned off. To enable DHCP from the front
panel:
1. Press and hold INPUT 1 and INPUT 4 together for 3 seconds

View Network Settings
1. Press and hold INPUT 3 and INPUT4 together for 3 seconds
The CS-88MHDBTS and CS-44MHDBTS will cycle through the following information: Device IP, Host IP, Subnet Mask, and
MAC Address.
View Firmware Version
To view the current firmware on the CS-88MHDBTS or the CS-44MHDBTS:
1. Press and hold INPUT 2 and INPUT 4 together for 3 seconds
Locking Front Panel Buttons
You have the ability to lock the front panel buttons so any accidental button presses can be ignored.

Web Interface
In order to access the Web Interface use a web browser (e.g. Internet Explorer, Chrome, Edge, Safari, etc.) and go to the
IP address of the Matrix.
Live Switch
Use this page to switch between inputs and outputs from the web interface live.
Link Info
Use this screen to monitor the EDID information of the connected input devices.

IR Setting
The IR switching allows you to route the IR signals on the IR outputs manually if you need to have a fixed route.
Note: By default the IR OUT is automatically routed with the active source.
Video Setting
On this screen you can modify the video signal that is being output by the matrix.
•either upscale, downscale or bypass the scaling feature
•Enable to disable the Output Signal Generator
oNOTE: The HDMI and HDbT outputs can be tested independent from each other.

Audio Setting
Here you can turn on or off the extracted audio for the SPDIF digital Coax or 3.5 Stereo ports. You can also set the audio
delay for the audio breakouts in order to combat any audio sync issues.
Audio Matrix and EX-Audio Matrix Mode
Here you can set the route of the audio in a matrix fashion for the extracted audio connections and bind the audio to
follow either the INPUT, OUTPUT, or set it to be Matrixed.
•Audio Delay – This allows you to change the audio delay to combat lip-sync issues on the extracted audio. Each
audio output can be delayed independently of the others.
•Bind to Input – The extracted audio binds to its corresponding input. E.g. Audio out 3 will always output audio
from INPUT 3.
•Bind to Output – The extracted audio binds to its corresponding output. E.g. Audio Out 3 will always output
audio from whichever input is selected for OUTPUT 3.
•Matrix – The extracted audio can be set manually to specific Audio Outs. E.g. Audio Out 3 will always play audio
from INPUT 4 regardless of what INPUT is selected for OUTPUT 3.

EDID Manage
Here you can set or control the EDID for the individual inputs.
System Settings
IP Settings – Here you can set the network configurations. E.g. set the static IP address, change the TCP port, or find the
MAC address.
Port Alias Setting – Here you can give the individual inputs or outputs an Alias, or a name. E.g. if INPUT 1 is a cable box,
you can name it “Cable”, or if OUTPUT 3 is the Master Bedroom TV, you can name it “Master Bed”

EDID Management
The CS-88MHDBTS and CS-44MHDBTS matrices have 29 pre-configured EDID settings.
NOTE: In order to maximize compatibility, by default the matrix is set to a 1080p EDID. When using 4K sources, you will
want to define a 4K EDID on that input (or read from the display).
To Change the EDID setting with the face buttons:
1. Press and hold the INPUT you want to change for 3 seconds8
2. Now "press" the desired INPUT/OUTPUT (Example: Setting EDID for INPUT3, use IN 3 & OUT 3)
to toggle through the available EDID options
3. Once you are on the EDID you want to select, press and hold the INPUT button again for 3
seconds. The LCD Screen will say "Please Wait", then "OK" once the EDID is set.
To change the EDID setting with the Web Interface, login to the Matrix through a web browser using the
IP address and then select EDID. From there you can select the desired/required EDID for each input
individually.
These are the pre-configured EDID settings that are available to toggle through:
0: 1080P_2CH(PCM)
1: 1080P_6CH
2: 1080P_8CH
3: 1080P_3D_2CH(PCM)

30: USER_EDID_ 1
31: USER_EDID_2
32: USER_EDID_3
The first 30 EDID settings cannot be changed. The three USER EDID settings are programmed using RS-
232 or the web interface. However, you can read an EDID from any output and it will automatically store
in USER EDID 1. Remember, each INPUT has an independent EDID setting and you may need to program
each one. To read and set an EDID to a specified input the steps are the same as switching the EDID
normally, except when you see the following figure, press and hold the original INPUT button again for 3
seconds. This will read, store, and set the EDID for that INPUT based on the OUTPUT selected.

IR Remote Control
The HDMI matrix can also be controlled by using the supplied IR remote. The left arrow button switches
to the previous button in the sequence, and the right arrow switches to the next input in sequence.
RS-232 TCP/IP Control Commands
These commands apply to both the CS-88MHDBTS and the CS-44MHDBTS. Where applicable, commands
that show 1-8 for inputs or outputs if used with the CS-44MHDBTS do not exceed 4 for the inputs and
outputs.
•Note: Add a return (Enter Key) after each command when using direct commands.
•Note: To send control commands to the Matrix, be sure to use the RS232-CTL port NOT the
HDbT RS232 port.
How to route RS232 commands when using the HDbT extenders:
To ensure that you format the commands correctly take note of the following:
1. You first send a route command then send the device command
2. You MUST know the baud rate of the device you are sending commands to.
3. For “hybrid” ASCII commands, it may be necessary to convert the numbers to a decimal value

Your first Command is for the route, and looks like this:
•A= Device Address (use this even if using a single unit, just put 00)
•OUT = The Output you want to route the forthcoming command to
•LEN = Forthcoming command length - for ASCII this includes EVERY character including spaces.
For HEX it includes only the BYTE count.
oEx1: If the ASCII command is "ka 0 1" the length is 6. Count spaces. NOTE: You can
exceed the length by 2 if unsure. If you exceed the length by more than 2 it will not
work.
oEx2: If HEX command is "6B 68 20 30 20 31" the length is 6. Do not count spaces. Again,
you can exceed by 2.
•BR = Baud Rate of the device you are sending to - You use a single digit to replace "x"
o0 - 9600, 1 - 14400, 2 - 19200, 3 - 38400, 4 - 57600, 5 – 115200
