2. Wire MS/TP cables to unit.
• The RS485 network cable connections are polarity
sensitive and must be connected the same way on
every device (i.e. + to + and - to -).
• Shield drain connections should be daisy chained in
the same manner as the signal cables for RS485. The
shield drain wire should be left unterminated at the
end of the cable and connected to shield only at the
network master controller. Shield wires must not be
connected to the RS485 connector on the FT-3500.
• The maximum number of devices allowed on an RS485
network segment without a repeater is 32. Adding more
than 32 devices to a single segment may reduce the
transceiver output voltage to a level that is too low to be
distinguished from background noise on the cable.
