1. Slide the cable holder rod with the cable clamp facing down into the pre-installed adapter situated under the rotary
joint (Fig.
). The rod is held in place using a 2-56 set-screw on the underside of the adapter.
2. Secure the clamp (facing down) onto the cable adapter rod using a #4-40 nylon set-screw (Fig.

2.2.3 Optical Fibers
The
ERJ
can be used alongside an optical rotary joint. If using optical fiber patch cords and a Fiber-optic Rotary Joint,
follow these directions. The system requires a signal patch cord (connecting to a light source) and a subject patch cord
(connecting to the experimental subject).
1. Connect the signal patch cord to the fixed connector of the optical rotary joint.
2. Install the
ERJ Holder
as shown in section
3. Select the subject patch cord(s) for usage. One side must be terminated with an
FC
connector and the other with
a
M3
or
Ferule/Sleeve
connector.
4. Connect the subject patch cord(s)
FC connector
to the rotary connector. Follow the directions in the manual of
the rotary joint.
5. Pass the patch cords through the
Through-hole
(Fig.
). Only
M3
or
Ferrule-sleeve
connectors are small
enough to pass through.
6. Do not secure the patch cord(s) in the
Horizontal Cable Holder
. For proper rotation, they must be hung loosely.
The patch cord(s) must not rub against the side of the through-hole.
