NOTE: The max length of the cable depends on which version of the Telemeca-
nique CPU hardware is being used. With versions of hardware coded lower than
V3 (E.g. CPU 47/11, 47/20) the length of the cable is limited to 3 meters given that
the serial port of the CPU is not optoisolated !!! In this case, whenever you need
to create a cable longer than 3 meters, it is advisable the employ a Telemeca-
nique device like XBT Z 9011 or 9012 to guarantee the galvanic isolation of the
serial line. Failure to adopt such a device can cause damage to the CPU’s serial
port !!!
If the CPU is of a hardware version coded higher than V3 (E.g.. CPU 47/411,
47/425 etc.) the max length of the cable relates to the particular characteristics of
the interface in Current loop (max 1000 meters) even without employing the
optoisolating device mentioned above, in so far as the CPUs have an internal cir-
cuitry created to guarantee the optoisolation of the line.
