• Use the cable LP-KIT007-001C between the FX16 Master
Controller and the first RS-232/RS-485 converter.
• The RS-232 port of the FX16 Master Controller has the possibility
to power the converter (for those converters that offer the
port-powered option).

• Run the 485 trunk cable separately from low-voltage power cables
and use a minimum of 30 cm (12 in.) separation per 230 V/30 A
circuits.
• Do not run the RS-485 cable in parallel to power cables for long
distances (>3 m [9.8 ft])
• Do not run the RS-485 cable close to transformers or
high-frequency generating equipment.
User Interfaces
The FX16 Master Controller can support up to two user interfaces at the
same time. An FX16 with an integral Medium User Interface (MUI) can
support one remote MUI. An FX16 without an integral MUI can
support two remote MUIs.
The remote MUI is available in two models: a panel mount nonisolated
version (up to 3 m [9.8 ft] from the controller) and a wall mount
isolated version (up to 1 km [0.6 miles] from the controller). The FX16
Master Controller can supply power to one panel mount MUI. See
Figure 30 and Figure 31 for installation details.
For the panel mount connection, use the cable connection kit
(LP-KIT007-000C), 3 m (9.8 ft) long, with a phone jack on the MUI
end and a screw connector on the FX16 Master Controller end.
