Figure 3.26 Ć Adding aNew Rack Drop to the End of the Remote I/O
Network (Coax)
Step 6. If a new drop is to be added along the cable route, use the
following procedure:
a.) Cut the remote I/O cable at the point where the new
drop is to be added.
b.) Terminate the cable ends with BNC connectors and, if
necessary, splice them with the new cable segments.
Test the spliced cable segments following the
instructions provided in section 3.4.
c.) For rack drops, connect the other ends of the new
cable segments with a tap attached to the new drop as
shown in figure 3.27. For Head drops, connect the
ends of the new cable segments to a BNC Tee
Adapter. Connect the Tee Adapter directly to the
Remote I/O Head or Remote Drive Interface Head.
Step 7. Make sure the drop number of the newlyĆadded Remote
I/O module, Shark Interface module, Remote I/O Head, or
Remote Drive Interface Head is properly selected before
you cycle power and resume Remote I/O network
operation.
Monitor drop 0 for the status of all remote drops to verify that no
drops have been adversely affected by the installation.
