4.7.1 Wiring in Hyper Terminal Mode
INTERFACE
AC INPUT
The wiring in hyper terminal mode is in Figure 12. The „CONTROL‟ cable is for different
purposes. „LAS_C‟ is for remote emission control, „AD/RS‟ is for control mode setting, „RDY‟
is a flag for system self-check accomplishment. „S_ERR‟ is for system error report. „EVCC‟ is
24V external power supply. All the signals in the „CONTROL‟ cable are 24V level, and are
relative to „EGND‟. If you don‟t use remote emission control, left „LAS_C‟ disconnected. The
„MODULATION‟ cable need to be connected when the laser emission is controlled by remote
modulation signal, otherwise can be left disconnected. The „RX‟ and „TX‟ of the „RS-232‟ cable
should be connected to the „RX‟ and „TX‟ of the PC, respectively. „AD‟ and „RS-422‟ should be
