2.2 Electrical & Optical Cables
2.2.1 Electrical Cables
The rotary joint is assembled using either HDMI or Harwin (6 or 12 contacts) electrical connectors. The number of
electrical contacts does not necessarily equal the number of recording channels. The system requires a signal cable
(connecting to a console, computer or other signaling device) and a subject cable (connecting to the experimental sub-
ject).
(a) Electrical Connectors
1. Ensure that the electrical connectors are free of dust using an air duster before installing the cables. When not in
use, install plastic caps on connectors for protection and cleanliness.
2. Connect the signal electrical cable to the fixed electrical connector (Fig.
3. Connect the subject electrical cable to the rotary connector (Fig.
4. If using the Horizontal Cable Holder, the subject electrical cable can be looped into the Cable Holder Standoff
(Fig. 2.5b) to provide extra torque. The cable is secured into the clamp (Fig. 2.5c) using a #4-40 nylon socket-head
cap screw. See section
2.2.2 Horizontal Cable Holder
The horizontal cable holder keeping electrical cables off-center can be added to increase the effective torque applied on
the rotor. To install the Horizontal Cable Holder:
