FBUS INTERFACE UNIT (if supplied)
OVERVIEW
Francis Searchlights FBUS data system facilitates control of up to 30 search-
lights from multiple control stations. To provide the required control response
whilst maintaining a low data rate for extended transmission distance, the
FBUS data system involves precisely timed control signals.
The FBUS interface offers a simplified communication interface to the FBUS
data system over a number of different physical layer communication stand-
ards and data rates. The system also facilitates long range communications
over LAN / Internet.
When used with Francis searchlights FBUS Control software the FBUS inter-
face can control networks of lamps over local communication systems or
globally via the internet.
POWER / FBUS CONNECTION
The FBUS interface obtains a supply from the FBUS data system, no external
power supply is required. The interface connects to the four wire FBUS sys-
tem like any FBUS system component. The four-wire interface provides 24V
supply and RS485 communications with FBUS.
EXTERNAL INTERFACE AND CONNECTIONS
The FBUS interface supports RS422 (4 wire), RS485 (2 wire), USB (VCP)
and UDP.
