Maximum cable length
The RF18xC can be operated with any reader configuration with a maximum cable length of
50 m. In some situations, longer connecting cables up to 1000 m are possible. Please note
that a transfer speed of 115.2 kbaud can only be guaranteed for a max. cable length of

Joining more than two cables to form a long cable should be avoided due to the additional
contact resistances.
