CHAPTER 1 SWITCHER SYSTEM OVERVIEW
1.1 Introduction
The MRM-602P Switcher is a high performance, zero-second latency switching
equipment with 6x2 transmission interfaces. Through flexible and multiple video format
modular designs - VGA, YPbPr, DVI or HDMI modular card, each of them is independent
of all other cards in the system and quite easily swap through 2 screws only, the
multimedia signals come from these interfaces sources that you can transmit them
simultaneously to the VGA and HDMI output display, thereby minimizing signals
attenuation and ensuring high definition, integrating high fidelity graphics and multimedia
signal output. It features advanced video signal processing with up to 1080P
de-interlacing and true seamless switching for 1:1 or Full-screen processional-quality
aspect.
The MRM-602P Switcher is used mainly in TV broadcasting projects, multimedia
conference halls, and large display performances, TV teaching and command control
centers. It boasts features of power interruption protection during power surge, LCD
display and synchronous and integrate audio/visual switching functions. Beside it also
supports a RS-232 or LAN communication port enables convenient communication with
remote control equipment to switch the multimedia signals. Through a standard TCP/IP
connection with seamless integration in any existing network for easy remote access.
With easy operation, the MRM-602P Switcher allows you to use both pushbuttons and IR
remote control to operate the device.

and vertical ratio as same as the input image comes from the video. That makes
the output image has no distortion.
- “Full” Aspect ratio mode: This mode modifies the original input image comes
from the video to fit the aspect ratio of your output display. Sometimes the
image will be distorted so that it can fit in with the screen of your output display.
Centralized control upon series connections via RS-485
Supports both HDMI and VGA output.
Supports RS-232 serial control.
Supports RS-485 serial control
Supports Ethernet control.
Supports Audio input/output
Remote controller for up to 12 meters wireless operation.
Hot pluggable and 1U rack design.

6.5.2 RS-485
RS-485 is a standard defining the electrical characteristics of drivers and receivers for
use in balanced digital multipoint systems. Digital communications networks
implementing the RS-485 standard can be used effectively over long distances and in
electrically noisy environments. The Switcher support up to two RS-485 ports allows you
to control more than one relative Device. If the master device is specified for IPM, it
allows you to control all the series devices with web browser. Remember all the ID of
each device upon series connection has to be uniquely.

6.5.5 Device ID Settings
Device ID Settings
The Device ID determines the position of a Matrix system. When multiple Matrix products
are connected to one PC or when the Matrix products are serially connected, the Device
ID decides which Matrix product is to be controlled. Device ID must not set to same
number. Use the ON/OFF switches 1, 2, 3, 4, 5 on the rear panel to set the ID number as
below:

CHAPTER 8 TROUBLESHOOTING
1. What to do if LCD is fail in display?
Answer: Check the connection of power cord is not loosening and the power cord is in a
good status having no any damage. Check the power source is normally.
2. What to do if the Switcher front panel keys switching not responsive?
Answer: The Switcher front panel keys employ scanning testing and require longer
response time. Press the keys for 2 seconds and then release. This way, key
switching will be responsive in operation.
3. What to do if the serial port (usually refer to the computer serial port) fails to control the
Switcher?
Answer: Check that the communication port set by the control software is correctly
connected to the corresponding serial port of the equipment. Also, check if the
computer communication port is in good order. Check the ID address and DIP
Switcher are configured correctly. Refer to 6.5.5 Device ID Settings.
4. What to do if the corresponding audio signal fails to output during Switcher switching?
Answer:
(1) Check if there is signal on the input end. If there is no input signal, it could be that the
input connection cable is broken or the connector gets loosen. You are advised to
replace the connection cable.
(2) Check if there is signal on the output end. If there is no output signal, it could be that
the cable is broken or the connector gets loosen. You are advised to replace the
connection cable.
(3) Check if the output port number is the same as the controlled port number.
(4) Check the connections of input and output ports are correctly.
(5) If none of the above circumstances happen, it could be internal failure of the product
itself. You must send for repair by qualified technical engineers.
5. What to do if you sense the power leakage during plugging or unplugging of the
input/output ports?
Answer: It could be that the equipment power is not properly grounded. You must
properly ground your equipment; otherwise product life can easily be shortened.

6. What to do if the Switcher panel keys and communication ports are out of order?
Answer: Check if the equipment power input is in good contact and the computer
communication ports are in good order. If yes, it could be some internal failure of the
product, please send for repair by qualified technical engineer.
7. What to do if operation and function failure occurred?
Answer: Check if the equipment and the Switcher system are in proper connection. If
the problem persists, send the product to the maintenance center for repair.
8. How to avoid the equipment failure due to the high temperature?
Answer: Place the equipment in a ventilate location. If it is still not to be improved,
please check with the build-in fan whether is damaged. Or contact your agency for
helping.
9. What to do if IR function failure occurred?
Answer: Check the battery of remote controller is NOT running low and the IR connector
is not loosening. Check whether the remote controller is aiming at the IR receiver
accurately.

Audio delay time is 16-bit data. (Unit: 5 ms or 10 ms)
Delay1 - The audio delay time low byte. (Bit0 – Bit7)
Delay
Delay2 - The audio delay time high byte. (Bit8 – Bit15)
The audio delay time unit decided by the DTUF flag of the extend information.
The maximum Delay decided by the DTMAX flag of the extended information.

CRC Calculation
CRC 0 = 0 (initial value)
CRC 1 = CRC_ TABLE [CRC 0 ^ Byte 1] = CRC_ TABLE [0x00 ^ 0x20] = 0x23
CRC 2 = CRC_ TABLE [CRC 1 ^ Byte 2] = CRC_ TABLE [0x23 ^ 0x01] = 0x9F
CRC 3 = CRC_ TABLE [CRC 2 ^ Byte 3] = CRC_ TABLE [0x9F ^ 0x06] = 0x8D
CRC 4 = CRC_ TABLE [CRC 3 ^ Byte 4] = CRC_ TABLE [0x8D ^ 0x03] = 0x93
