SETUP INTERLOCKS

The Wavelength Interlock Replacement Kit includes a male

D-SUB with the passive interlock pins shorted and a BNC

terminator.

1. For the passive interlock, on the back panel, short PIN 1

2. For the active interlock, on the back panel, insert a BNC

terminator in the ACTIVE LOCK BNC port.

3. On the front panel, the keyswitch must be on UNLOCK to

enable the current to the QCL.
