1. Introduction
The RM42C is an 18G HDMI video matrix switch with 4 HDMI inputs and 2 scaling HDMI
outputs. Each input and output supports up to 4K60 444 HDMI 18G video. The outputs
can be individually scaled for 1080p or 10.2Gbps compatibility (labeled as HDBaseT in the
menu). De-embedded audio as analog L+R and optical SPDIF (TosLink) is available for
both outputs. The RM42C Matrix can also automatically control the display device using
RS232, CEC or IR when the last input signal is lost, or when the first video input is
detected. The RM42C can be controlled from the front panel, RS232, IR, or IP commands.

Color
Description
Blue
The Matrix is active and fully controllable
Red
The Matrix is in standby mode, this state can be
changed by using RS232, IP commands, or from
the Web GUI interface.
5.4.2 Auto LED and Button
The green AUTO LED for both outputs A and B is lit when that channel has
its Auto Detection mode active. Auto Detection mode will detect any new
HDMI signals and immediate switch to the input. If the currently selected
input is removed then the switcher will switch to the next available input, or
remain on the current input if there are no active HDMI input signals.
The change the Auto Detection mode, press and hold the button for that
channel for 3 seconds until the Auto LED changes state.
5.4.3 Selecting Inputs
Manual Selection of the inputs is done by briefly pressing the push button
repeatedly for that channel until the desired input is selected. Manual
selection is always possible, irrespective of the Auto LED state. Selected
inputs that have no signal will be indicated by a flashing LED.

7. Using the Built-In Web Interface
The RM42C Matrix has a built-in web interface to provide a means of controlling or
configuring various settings. There are seven pages available, each of which
will be outlined in detail in the following sections.
The seven pages are:
1. Status –Displays information about the firmware and IP settings
2. Switch –Control the video routing and enabling the test pattern mode
3. Input –Displays information about the input signals and EDID settings
4. Output –Displays information about the output signals and scaler options
5. Network –Allows basic network setting management and login options
6. System –Serial baud rate, test pattern setting and firmware update
7. Control –Auto Power Control Settings and Commands
Note these seven pages are only accessible in Admin mode, when User mode is used
only the Status and Switch pages are available.
To access the web interface, enter the IP address of the Matrix into
the address bar of any web browser. The factory setting is DHCP. If the IP address is not
known, use the RS232 commands given in the Network Settings section “r ip addr!” to
discover the IP address of the Matrix or use a network scanning tool such as Fing. After
entering the IP address the following log in screen will appear:
Select the Username from the list and enter the password. The default
passwords are:
Username User Admin
Password user admin
After entering the log in details, click the LOGIN button and the following
Status page will appear.

10
■ Status Page
The Status page provides basic information about the product Model name,
the installed firmware versions and the network settings. This page is visible
in both User and Admin modes.
The buttons at the top right of the web interface are always available and
provide the following functions:
● The Log out button will disconnect the current user from the session
and display the log in screen.
● The Power On button changes the power status of the Matrix between
On and Stand-by mode.
■ Switch page
The Switch page allows selection of the input sources, set the Auto Switch
Mode, and to enable the test pattern mode.

11
■ Input page
The Input page provide information about which inputs are connected and
have a signal present. The inputs can be giving more meaningful names, if
desired. The EDID column provides a list of EDID options for each individual
input.
The following EDID options are available in any of the EDID drop-down lists:
1080P, Stereo Audio 2.0

Note that the User 1 and User 2 are global EDID memories only. Any inputs
that is set to one of these memories will always use the same EDID data from
User 1 or User 2 respectively.
This page also provides a means of sending a binary EDID image file to
either User 1 or User 2 EDID memories:
1. Select the binary EDID image file on your PC by click on the Browse button.
2. Select either User 1 or User 2 from the drop-down list.
3. Click the Upload button.
The EDID data from any input or from the User 1 and User 2 locations can
be read and stored on your PC.
■ Output page
The Output page provides information about the signal status of the outputs.
The outputs can also be assigned meaningful names, is desired.
The scaler mode menu provides the following options:
Off
No scaling.
4K→1080P
Downscale to 1080p, if needed.
HDBT Mode
Downscale to no more than 10.2Gbps for HDBaseT
compliance.
Auto
Scale to match the display requirements.
The ARC buttons enable or disable the ARC decoding to the analogue
audio outputs.
The Stream buttons enable or disable the output signal for the respective
output.
The HDCP buttons enable or disable HDCP at the respective HDMI output.

13
■ Network page
The Network page allows the configuration of the network settings. Note that
the IP address boxes are only accessible when the Mode button is set to
Static.
The log in passwords can be changed on this page.
Note that any changes to this page will require the new details into the web
browser and/or the log in screen.
■ System page
The system page allows setting of the control RS232 port baud rate and
changing the test pattern output.
This page is also used to install new firmware updates, restore the factory
default settings and reboot the Matrix.

14
■ Control page
The Control page is used to set the RS232 or IR display device power on/off
commands for the Automatic Power Switching mode. When this mode is
enabled, the display power off and power on commands will be sent from
RS232-A/RS232-B or IR-A/IR-B outputs after the defined Power Off Timeout
and Power On Timeout values respectively.
The Control page has three modes: RS232, CEC or IR. Power On and Power
Off commands can only be entered for the RS232 and IR modes. The
CEC mode power on and power off commands are provided by default and
cannot be changed. Only use CEC mode with displays that support CEC
commands.
▪RS232 Setting 1 and RS232 Setting 2
Select the desired tab and configure the RS232 port settings to match the
display device requirements. Select either ASCII or HEX for the command
format and enter the Power Off and Power On commands with the appropriate
command termination mode: None, CR, LR or CRLF.
If the display device is connected to the respective RS232-A or RS232-B port,
use the Test buttons to confirm that the command is correct. Once the
command is valid, use the Save button to store those commands in the Matrix.
Note that ASCII commands can use any ASCII character, but HEX command
must use hexadecimal notation using hexadecimal value pairs separated by
spaces.

15
▪IR Setting 1 and IR Setting 2
This page requires that the IR commands are available in plain text files
using the CCF IR code format.
1. Select the desired IR Control Setting tab.
2. Click the Load button to load the respective IR command. If the display
device only support a power toggle IR command, then use the same file
for both the Power On and Power Off modes.
3. Use the Test button to confirm that the command functions.
4. Click the Save button to save both IR commands to the Matrix.
8. ASCII control command
The Matrix also supports ASCII control. You need to a RS-232 phoenix connector male
head to RS-232 female head with DB9 serial cable and a RS-232
male head with DB9 to USB male head serial cable. The phoenix connector
male head is connected the RS-232 port of the Matrix, and the USB head of
the serial cable is connected a PC. Open any of a Serial Command tool on
PC such as “Docklight” to send command to control the Matrix. Please see the
following connection diagram;

16
Important:
1. All messages sent to the Matrix must be terminated with an exclamation
mark (!). Any carriage return that is present after the end of the
command will be ignored.
2. All spaces shown in the commands are required.
3. All response messages are terminated by a CR/LF sequence.
4. When all four inputs are requested by the same command, the
response will report each input on a separate line.
5. When both outputs are requested by the same command, the response
will report each output on a separate line.
The ASCII list about the product is shown as below;
