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 left disconnected. The PE of the cable for “INTERFACE” is not shown in Figure 3,
