The JVA Perimeter Patrol Interface provides Ethernet connectivity for the Z-Series Energizers and monitors. On the Keypad bus port it connects to 1 - 14 Z-Series devices. On the TCP/IP port it connects over LAN or WAN to a PC running Perimeter Patrol. By using multiple TCP/IP interface boards a system can be expanded to more than 100 zones. This interface handles pulse synchronisation for all connected Energizers. HLI code and an SDK are also available to enable integration into other systems.
