4. Connect the Bus Through connector of ERD 1 to the Bus Input connector of
ERD 2 (item D of
Figure 21
).
5. Place the bus defeater (
Figure 18
) onto the Bus Through connector of the
ERD (item E of
Figure 21
).
Note: Ensure to terminate the External bus with an NKT Photonics bus defeater,
Without the bus defeater, the interlock circuit remains open disabling laser emis -
sion.
6. Using an RF coaxial cable, connect the RF BNC port of the ERD 1 (item A of
Figure 21
) to the RF 1 port of the SELECT (item B of
Figure 20
).
7. Using the other RF coaxial cable, connect the RF BNC port of the ERD 2 (item
B of
Figure 21
) to the RF 2 port of the SELECT (item A of
Figure 20
).
