Introduction
1.1 About HDMI Matrix Switcher CSW-HD880
CSW-HD880 is a high-performance digital signal switcher t hat ca n be used for cross switching of
multi computer and audio signal. Independent HDMI com ponent and I/O terminals make each
component signal transm it and switch separately; this design can reduce attenuati on of signal
transmission to minimum and out put the image and audio signa l i n high-fidelity quality.
CSW-HD880 mostly apply in broadcasting TV en gin eer ing, m ulti-m edia meet ing roo m, bi g scre en
display engineering, television education, com man d control center and other fields. With RS232
interface, it can be worked with PC, remote control system and any other far-end contr ol system
devices.

5. Operation of the EDID management
MHD matrix switcher is b uilt in the EDI D ma nagement database. The EDID management can be
automatically shake han d, or manual exchanged, and factor y restore.
6.1 EDID automatically shake hand
The CSW-HD880 is built in the EDID data, which can com mun icate with the displayers and v ideo
source automatically. When the displayers or video sources are connected to the MHD matrix switcher,
they will share the EDID/D DC information with the matrix sw it cher.
The CSW-HD880 communication solution is like th i s:
The MHD EDID database includes most popular displaying data, but not all the displaying data
because of the capability and firmware limitation. S o, w e ca n manually refresh the E DID data to update
the EDID data base.

6.2 EDID management of MHD matrix
The RS232 commands for EDID management of MH D mat r ix models include: “EDIDMAuto.”
”EDIDMInit.” and ”EDIDM[X]B[Y].”, (Please notice the text-transform, and the dot in behind.)
6.2.1 Erase and Refres h t he E DID data
The EDID refresh ports have the priority grade when the matrix is executing the EDI DMAuto function,
ranging from output 1 to out put 8 in pri or it y order . I t means t he output 1 is the most prior to exchange
the EDID data, and then the output 2 is the second prior to exchange the EDID data. And, the output 8
is the last prior.
When the user carries the EDID erase/refresh function, t he M H D w il l detect the output priority and
exchange the EDID data w ith t he available most prior output port.
Priority of CSW-HD880
6.2.2 Auto EDID management
The only way for auto EDID man agement is by sending RS232 c ommands “EDIDMAuto.”. When the
“EDIDMAuto.” is sent, the MHD matrix switcher wil l copy the EDID data from th e m ost pr ior output port.
It means the MHD will er ase the o ld EDID d ata, and fully copy the EDI D data fr om the disp layer whi ch is
connected to the most prior out put port. The feedback command is “EDIDMAuto”.
6.2.3 EDID restore to factory default
There are two ways to do restor e E DI D ma nagement: by RS232 co m m and or by buttons.
EDID management by RS 232 command
When we send the “EDIDMInit.” to the MHD matrix switcher, it will recover the factory default EDID data.
The feedback command is “EDIDMInit”.
EDID management by but t ons
Press the button “INITIAL” on the front pa nel, the MHD matrix switcher wil l restore the EDID to factory
default.
6.2.4 Manually EDID switching
There are two ways to do manua l ly EDID management: by RS232 c ommand or by buttons.
EDID management by RS 232 command
When we send the RS232 command “EDIDM[X]B[Y].”. The matrix will copy the EDID data of output[X]
to the input[Y]. The fee dback command is “EDIDM: [X]To[Y]”.
EDID management by but t ons
Press the button “EXTERNAL” then input button [X] , and t hen pr ess output button [Y ]. The matrix will
copy the EDID data of the out put [X] t o the input[Y].
NOTICE: If the output[X] does not connect to an activ e displ ay, the EDID management w ill t ake no
action.
6.3.5 RS232 feedback:
When a RS232 command is correctly sent, all the connected displayers w il l be blank for 2~3 seconds
and recover again. And, the MHD matrix switcher will send out the RS232 feedback command.

Oper ation: Press buttons in this order: “ 3” in I NP UT area, “1” in OUTPUT area.
7.2 Command Format of the Switching Operation
With the front control panel, t he switcher could be control direct ly and rapidly by pressing the but tons
under below format.
“Menu” +“Input Channel” +“Output Channel 1”
“Menu”: “AV”, “INITIAL”, “EXTERNAL”
“Input Channel”: Fill with t he number of input channel to be controlled
“Output Channel”: Fill with t he number of output channels to be cont r olled
7.3 Examples of Operation
Example 1：T o tr ansfe r video an d audio sig nals from input ch annel N o.1 to ou tput cha nnel

Then, switching OK ! audio/video switching from “1” to “3” and “4”
7. Usage of the Remote Controller
With the infrared remote cont r ol ler, the matrix switcher could be control remotely. Because the function
buttons on the remote cont r oller are t he same with the ones on the fr ont control panel, the remote
controller shares the same control operation and co m m and format with the control panel.

10. Troubleshooting & Maintenance
1) When the output image in the destination device connected t o t heHDMI Matrix (MHD) has ghost,
such as the projector output with ghost, please check the proje ctor’s setting or try another high
quality connection cord.
2) When there is a color losing or no video signal output,，M aybe the HDMI cables haven’t bee n
connected asHDMI criterion
3) When the remote controll er doesn’t works:
A. Maybe the battery is run out of, please chang e a new one.
B. Maybe the controller is broken, please as k the d ealer to fix it.
4) When user can not control the HDMI Matrix (MHD) by computer through its COM por t , please
HDMI Matrix Switcher
16
check the COM port numb er in t he software and make sure the CO M por t is i n good condition.
5) If there is not “beep” sound when switching the I/O signal, pl ease make sure the beeper is
switched-on. If so, the beeper inside the matrix may be broken. Pl ease send it to the dealer for
fixing.
6) When switching , the beeper beeps but without any output image：
A. Check with oscilloscope or multimeter if there is any signa l at t he input en d. If t here is no sign a l
input, it may be the input connection cord broken or the connectors loosen.
B. Check with oscilloscope or multimeter i f ther e is any signal at the output end. If there is no
signal output, it may be the out put connection cord broken or the connectors loosen.
C. Please make sure the destination device is exactly on the controlled output channel
D. If it is still the same after the above check in g, it may be something wrong i n t he switcher.
Please send it to the dealer for fixing.
7) If the output image is interfered, please make sure the sy stem is earthed well.
8) If the static becomes stronger when connecting the H DMI connectors, it may be due to the
incorrect earthling of the p ow er supply, Please earth it agai n cor r ect ly, and otherwise it would brin g
damage to the switcher or shor t en its nat ural life.
9) If the Matrix can not be controll ed by the keys on the front panel, RS2 32 por t or remote controller,
the host may has already been broken. Please send it to t he dealer f or f ixi ng.
