Communication ports
Port E1
•
For Ethernet LAN, BACnet IP, and Modbus TCP/IP
communication at 10 or 100 Mbps, half duplex
(10/100 BaseT Ethernet):
•
Both
Assigned
(default) and
DHCP
IP addressing are supported
and DIP switch selectable
Port S1
(BACnet MS/TP):
•
For communication with Open and third-party controllers via
BACnet MS/TP at 9600 bps, 19.2 kbps, 38.4 kbps, or 76.8
kbps (DIP switch selectable). Default is 76.8k bps.
•
A
BT485
may need to be installed on
Port S1
if the i-Vu Open
Link is at the beginning or end of a network segment. The
BT485
adds bias and terminates a network segment.
Port S2
(Configurable EIA-485/EIA-232 port for third-party network
connections, including):
•
Modbus (RTU) - 9600 bps, 19.2 kbps, 38. 4 kbps
•
LonWorks (requires SLTA-10 adapter)
Local Access
(115.2k bps port):
•
For i-Vu Open Link configuration using a terminal program
(such as Windows Hyperterminal) via RS-232
•
For system start-up and troubleshooting using Carrier tools via
Rnet
Real time clock
Battery-backed real-time clock keeps track of time in event of
power failure
Battery
10-year Lithium CR123A battery provides a maximum of 720 hours
data retention during power outages. The battery retains time,
trend data, alarm data, configuration data, and operating
parameters in the event of power failure.To conserve battery life,
battery backup turns off after a specified number of days defined in
the controller driver.
