Coaxial Cables
For coaxial-attached printers, each printer is connected to the computer on a
separate port. The cable cannot be longer than 1500 m (4920 ft).
The following diagram shows how your printer connects to the computer.

If you install a signal cable outside the building, order a station protector kit to
protect your printer from lightning. You can order the kit from your IBM marketing
representative (allow a lead time of 120 days).
One kit (IBM part 1830818) provides two protectors. You need one protector at
each end of the coaxial cable when the cable is installed outdoors (either above or
below ground level). One attachment kit (IBM part 1833106) provides the
necessary hardware for the attachment of the two protectors. Individual protectors
are available for replacement (IBM part 5252899).
If you are ordering cable from sources other than IBM, see Appendix B, “Cable
Specifications and Assembly of the Cables,” for specifications.
Note: For information about assembling coaxial cables and connectors, see
Appendix B, “Cable Specifications and Assembly of the Cables.” For additional
information about coaxial cable installation, see

Coaxial Cable and Accessories for Attachment to IBM Products, GA27-2805.
