RS-485 Junction Box 
Provides a means for hard-wire connections and incorporates 
protection circuitry to prevent electrostatic surges (which may 
occur on the field wiring) from reaching the Islander. 
 
Power Conditioner 
Provides clean power to the Islander. Provides transient and 
common mode protection. 
 
Pump Control Units 
Required for mechanical pumps and some electronic pumps. 
Microprocessor controlled. One unit controls up to four fueling 
positions (up to 8 fueling positions in self-contained unit) to a 
maximum of 32. Certain applications may require peripheral 
pump control units. Battery-backup, three solid state relays for 
each pump/dispenser, manual override switches. Wall-mounted 
or accommodated in island reader pedestal. 
 
Electronic Pump/Dispenser Interfaces 
Certain pump interfaces use controller boxes or special interface 
devices. When installing any electronic pumps or registers, 
follow the manufacturer's specifications. GASBOY 9800 Series 
electronic pumps and dispensers can be connected to the 
Islander via the RS-485 data loop. A Current Loop interface is 
available from GASBOY and is required for Gilbarco electronic 
pumps. For Islander II, Tokheim and Wayne use a controller 
box to control the pumps. The CFN system interfaces with this 
control box.
