Users who intend to use a gating signal should set the UC-2000’s gate input logic to internal Pull-Down
(normally off) mode. This prevents the beam from being enabled unless a high level (+3.5 V to +5.0
VDC) signal is applied to the Gate input connector. In the pull-down (normally off) mode, an asserted
logic low signal, short circuit to ground, or an open or disconnected Gate input locks the beam off.
Many CO2 lasers operating in applications requiring short gating pulses at repetition rates below 500 Hz
will exhibit some leading-edge overshoot regardless of the PWM frequency. This occurs because a
cooler lasing medium (the CO2 gas) is more efficient than a hotter one. The overshoot effect is more
pronounced at lower gating frequencies because the gas has more time to cool between PWM
Command signal pulses.
Interface Connections
The User I/O connections section includes subsections:
•
Interface A (DB-9) connector
•
Interface B (RJ45) connector
Two built-in interface options are available for integrating OEM v30 lasers—a DB-9 and an RJ45 interface
connector. The RJ45 (Interface B) connector is useful when integrating v30’s into existing integrated
laser systems previously configured for an RJ45 interface. For new Firestar OEM v30 installations, use
the DB-9 (Interface A) connector. Although both interface connectors provide the same functionality,
the DB-9 connector contains an additional output, Lase Indicator, that activates when the v30 is actively
lasing.
Interface A (DB-9) connector
Warning: Serious Personal Injury
The UC-2000’s default gate logic is factory set to internal Pull-Up (normally on) mode so that an
open (disconnected) Gate input causes the laser to turn on. This functionality allows the user to easily
test and verify laser operation prior to integration.
In an integrated system, you should configure the UC-2000’s gate input logic to internal Pull-Down
(normally off) mode. This prevents the beam from being enabled unless a high level (+3.5 V to +5.0
VDC) signal is applied to the Gate input connector. In the Pull- Down (normally off) mode an asserted
logic low signal, short circuit to ground, or an open or disconnected Gate inputs locks the beam off.
