DB-9 connections
32-1 lasers are equipped with a female DB-9 connector mounted to the sidewall of the laser.
The DB-9 connector provides the user with a convenient method for monitoring fault condi-
tions (over temperature, control/RF circuitry failure, etc.) and adds, remote keyswitch (relay or
switch), and remote LED indicator capability. These signals allow you to connect remote key-
switch, LASE, and ready (PWR) indicators to a remote operator’s station or connect a remote
interlock safety switch to interlock equipment doors or panels.
Caution
Do not ground the Remote Keyswitch input to an external circuit—
this will damage laser circuitry. Any external circuit(s) connected to
these terminals must be oating with respect to ground. We recom-
mend using “dry circuit” (zero voltage) switches or relay circuitry.

Damage
You can control 32-1 lasers from an alternate user-supplied PWM signal source. See
Controlling laser power in the Technical Reference chapter for control signal de-
scriptions.
