4.2.18.1.2 The REA JET print head cable
The data connection between the REA JET HR pro 2K/4K control device and the print heads is a
high-speed communication interface. The requirements with regard to cable quality and transfer are
comparable to those of a CAT 6 network cable. With the application of LVDS technology, this
connection is particularly resistant against external influences. The REA JET print head cable has
been specially developed for these requirements and is drag-chain compatible.

Due to the high data transfer rate and the importance of print
head cables, REA JET urgently recommends using only
genuine REA JET print head cables.
