Appendix A: RF Driver D-sub 15 Connector
PIN 7 Gate is an active HIGH lasing enable input. Gate is pulled LOW internally
(processor controlled 10k pull down resistor). To initiate lasing, both the Gate
(PIN 7) and Gate-2 (PIN 10) input lines must be pulled HIGH externally by user.
PIN 8
Delay Enable is an active HIGH input. When active, while operating in the
OEM mode (PIN 6 HIGH), a 5 second delay is enforced every time the DC
supply electrical power is cycled. PIN 8 must be enabled to operate in the Safe
CDRH mode. When active, while operating in the safe CDRH mode, a 5
second lasing safety delay is enforced every time the Key Switch is cycled.
The Delay Enable line is internally pulled HIGH by a 10k resistor R36. User
must pull PIN 8 LOW to suppress the safety delay (not recommended).
PIN 9
Discharge Conditioning active HIGH enable input line. PIN 9 is internally pulled
HIGH by a 10k resistor R35. User must pull PIN 9 LOW to suppress Discharge
Conditioning.
PIN 10 Gate-2 is an active HIGH lasing enable input. Gate-2 is pulled LOW by an
internal 10k pull down resistor R100. To initiate lasing, both the Gate-2 (PIN
10) and Gate (PIN 7) input lines must be pulled HIGH externally by the user.
Additionally, Gate-2 is wired directly to the external BNC connector.
PIN 11 AVC (Analog Voltage Control) input. See definition of PIN 5. A 0V DC to 5V
DC analog voltage on PIN 11 results in a proportional 0% to 100% Pulse Width
Modulated (PWM) laser output. The PWM frequency is 2.5 kHz. To enable the
internal PWM drive signal in the AVC mode: PIN 5 must be held LOW by user,
Gate-2 (PIN 10) must be pulled HIGH by user, Gate (PIN 7) can be left open
(NC) or pulled HIGH by user and a non-zero voltage between 0V DC and 5V
DC must be present on PIN 11 for lasing to occur. By the way of Example 1,
1V at this pin will cause the PWM to operate at a 20% duty cycle, 3V at 60%,
etc. (Note: Gate (PIN 7) is pulled HIGH internally by the processor. PIN 7 is
functional as a lasing sizable when pulled LOW by the user.)
