Modbus Card --- provides direct integration of UPS information (meters and
status) to a building management system (BMS) using the Modbus RTU
protocol.
•
ConnectUPS -X Web/SNMP Card --- provides remote monitoring through a Web
browser interface, e-mail, and a network management system (NMS) using
SNMP; connects to a twisted-pair Ethernet (10/100BaseT) network.
•
Modem Card --- provides “out-of-band” remote notification and monitoring
using modem communication directly to cell phones and pagers.
•
Relay Interface Card (AS-400) --- provides a voltage-free ”true relay” interface
for IBM AS/400 computers, other relay connected computers, and industrial
applications.
