SUMAVISION EMR Operation Introduction
45 /53
Solution:
EMR can be allowed to leave the factory only if the test ensures that all function indicators
meet the requirements. Therefore it is almost unlikely that the LCD module of the device is
broken, thus this cause can be excluded; check the power lead of the device to confirm
whether there’s any damage to the surface of the power lead, check the quality of power
socket to confirm whether the supply voltage is normal.
In case of fault in the power lead, suggest replacing he power lead to ensure smooth
signal transmission inside the power lead;
In case of fault in the power socket, suggest checking whether the power supply switch of
the power socket is on first; if the power supply switch is on and the power supply to the
slot where the faulty device is located is normal, but the LCD is still abnormal, suggest
checking whether the fuse on the socket is broken, and replacing the fuse.
If the foregoing solutions can’t be enough to solve the problems, it is suspected that the
LCD module is damaged. Please notify the After-sales Technical Support Department of
Sumavision for solution.
7.1.2 ASI 5-channel input card fails to refresh any input
signals.
Reasons for such fault:
The input signal or the line for input sign is abnormal.
Solution:
Confirm the board card of the device with normal input signal can receive which kind of
signals; check the cable for input signal is exempted from short circuit and open circuit;
check the port that which is connecting the cable for input signal is existing refresh port of
the device.
7.1.3 ASI 4-channel output card fails to output the decoding
normally
Reasons for such fault:
The input program source is abnormal
The output bit rate overflows
Solution:
Confirm normal input program sources of the input board card, without video & audio loss;
modify the settings of output system bit rate to make the bit rate be larger than the valid bit
