link. The Station Controller system with SiteOmat enables real-time monitoring of a vehicle
refueling process including Volume, Price and all vehicle details.
The SiteOmat Station Controller supports exporting (transactions) and importing (Negative/Positive

1-3. ORCU
Orpak Controller Unit (OrCU) is a complete forecourt controller with its own embedded operating
system (see Figure 1-2). The unit consists of an embedded hardware platform with a solid state
Flash hard disk, Real Time Clock (RTC) with back up, along with surge suppressors for transient
and noise immunity. It also includes power fail recovery mechanisms.
OrCU features two separate and isolated networks (TCP/IP over Ethernet). One network links the
Islander PLUS system components. The second network is intended for external remote
communication (Head Office, 3
rd
party systems). This network is protected by SSL security.
OrCU includes a Security Access Module (SAM) for enhanced data protection and safe security key
storage (Triple DES encryption). OrCU includes a built-in server for Web access through Internet
