The debugging Interfaces designated for the main control panel are serial interface J7 (RS232
signals), FPGA JTAG interface J3, FPGA AS interface J4, and SD interface for programming before
shipping. Use of these debugging Interfaces is restricted to developers only.
2.3.1.3 Power input and indicator lights on the Main Control Panel
Digital power input and indicator lights
Power input of the digital part is 5V, and it can be tested via testing point TP15 (multimeter shall be
adopted for testing, and during the testing, the red probe shall be connected to TP15, while the black
probe shall be connected to the metal part on the housing). The 5V power input is accompanied by
the fuse F2. Normally the fuse will not be blown since the power supply of the device is equipped
with surge protection. If a short circuit occurs under the input of 5V of power, the power supply will fail
to work properly and a buzzing sound can be heard.
All digital power supplies of the main control panel are equipped with an indicator light and testing
point, and corresponding relationships between the digital power supply, indicator light, and testing
point is shown in the Table 2-2.
