Input/output signals
Firestar’s input/output signals are divided into three categories: auxiliary DC power, input signals, and out-
put signals. Signals in each category are fully described in the section below. Figure 3-6 illustrates the pin
arrangement of the
User I/O
(15 pin female D-type subminiature) connector on the laser’s rear panel.
Note:
See
DB-9 connections
later in this section for signal descriptions and pinouts of the SA model’s
side-mounted DB-9 connector.
Caution
possible
equipment
damage
Turn off DC power before installing or removing any plug or cable
from the
User I/O
connector. Ensure that user connections are made
to the appropriate pins and that the appropriate signal levels are ap-
plied. Failure to do so may damage the laser.
