Table 4-7 DB-9 Connector input signal specications.
Pin # Input Signal Name Input Specications
3 PWM (+) Apply a 5VDC Pulse Width Modulated (PWM) signal to the
4 PWM (-) laser’s control input connector.
6 Remote Keyswitch Input Circuit” (zero-voltage) external switches to prevent inter-
nal circuit damage.
Table 4-8 DB-9 Connector output signal specications.
Pin # Output Signal Name Output Specications
1 Fault Shutdown Output Active Low output signal: O: + 15 VDC, 5 mA into 3
kOhm;
7 Remote Keyswitch Output 50 mA maximum @ 30 VDC. Output active (+30 VDC)
when Keyswitch ON or bypassed (OEM models).
8 Remote Lase LED Output Current-limited to 11 mA @ 2.4 VDC maximum. Voltage
output is pulse width modulated at input PWM
signal frequency, not a steady state on/o signal.
9 Remote Ready LED Output Current-limited to 11 mA @ 2.4 VDC maximum.
2 Signal Ground Signal ground for pins 1, 8, and 9.
