Connecting power
The External bus includes an extension of the interlock circuit. The defeater plug
loops the circuit at the last External bus connector in the system with no other
devices attached to the bus chain. If no defeater is used, the interlock circuit will
be open and disable the laser in the chassis in the same manner as the door
switch opening. The defeater is included with the ADJUSTIK, it is a standard male
DB-15 connector with the necessary pins looped back – see
Table 12 on page 79
.
Connecting power
Power is supplied to the laser through the rear AC input connector. The
connector is a standard C-14 type designed for use with an AC power cord that is
fitted with a C-13 connector. Electrical and cable specifications are listed in
Table 11
.
Table 11 Power specifications
Connecting modulation signals
Input and output wavelength modulation signals are described in chapter 2:
“Modulation”
. The signals are connected to the DB-9 pin connector on th rear
panel, see
“Modulation input/output” on page 97
.
Connecting the trigger input or output
The laser includes a trigger logic input/output signal as part of the Modulation
connector (see
Table 18
). The trigger signal can be used to either initiate or
indicate laser emission.
Input trigger
When set as an input a positive active high signal must be applied to the trigger
pin to initiate emission. The diagram
Figure 58
shows the trigger input.
