D20i Signal Interface and Pin Description

1(PWM Orange and white)

RF Enable

TTL logic input

1=RF ON,0=RF OFF;1KΩ impedance.

This input turns on the laser.(See also Pin 7,Control Enable, below)

2(+15V Orange) +15 VDC±0.5VDC,0.25 A Max output for customer use
3(Laser Green and white)

Laser ok

TTL logic output,1=LASER OK,0=LASER Fault;

Output is asserted when no faults(SWR, Temp or Volt.)are detected

4(Temp Blue)

Temperature OK

TTL logical output,1=Temp ok,0=Temp fault;

Output is asserted when temperature is below 60℃

5(Volt Blue and white)

Power and voltage OK

TTL logical output;1= voltage ok,0=voltage fault;

Output is asserted when DC supply voltage is below max. value

6(GND Green) For internal use. must be grounded
7(Enable Brown and white)

Control enable

TTL Logical input;1= Laser control enable,0= Laser controlled disabled

This input must be asserted before RF enable can be used to turn on the laser.

8(GND Brown)




1) The connector uses the RJ-45 type

2) These specifications are subject to change
