1.2.2 system controller interface
The system controller can connect 3 charge amplifiers and 1 IO controller, with 3 rs232/rs465, 4 USB and 1 network interface.
1.2.1 amplifier interface
The charge amplifier supports 4, 8, 12 channels (optional) sensor input, DB15 interface output, and the working voltage is DC12V.
1.2.1 I / O controller interface
IO input and output controller, with 16 isolated input, 16 isolation output, DB37 output interface, Working Voltage DC12V.
2.1 sensor layout
It supports multiple sensor layout modes such as 2, 4, 6, 8 and 10 per lane, supports up to 5 lanes, 32 sensor inputs (which can be expanded to 64), and supports forward and reverse two-way detection modes.
DI control connection
16 channels of DI isolated input, supporting coil controller, laser detector and other finishing equipment, supporting Di mode such as optocoupler or relay input. The forward and reverse directions of each lane share one ending device, and the interface is defined as follows;
|Ending lane||DI interface port number||note|
|No 1 lane(forward ,reverse)||1+、1-||If the ending control device is optocoupler output, the ending device signal should correspond to the + and - signals of IO controller one by one.|
|No 2 lane(forward ,reverse)||2+、2-|

After the trigger control end of forward mode is configured, the reverse mode does not need to be configured, and the system switches automatically. The interface is defined as follows:
|Lane number||Forward trigger||Tail trigger||Side direction trigger||Tail side direction trigger||Note|
|No1 lane (forward)||1+、1-||6+、6-||11+、11-||12+、12-||The trigger control end of the camera has a + - end. The trigger control end of the camera and the + - signal of IO controller should correspond one by one.|
system usage guide
Preparation before instrument setting.
3.1.1 set Radmin
1) Check if Radmin server is installed on the instrument (factory instrument system). If it is missing, please install it
2）Set Radmin, add account and password
3.1.2 system disk protection
1)Running the CMD instruction to enter the DOS environment.
2)Query EWF protection status (type EWFMGR C: enter)
(1)At this time, EWF protection function is on(State = ENABLE)
(Type EWFMGR c: -communanddisable -live enter), and state is disabled to indicate that EWF protection is off
(2)At this time, EWF protection function is closing (state = disable), no subsequent operation is required.
(3) After changing the system settings, set EWF to enable
3.1.3 Create auto start shortcut
1)Create a shortcut to run.
(2) Setting parameters
