The Dualcom S main menu appears:
Note: At the bottom of most screens are help areas that provide information on
how to navigate and edit settings within the serial/telnet interface.
TCP/IP Connection
The Dualcom S administration can be performed either by Telnet or through a
web browser. The Telnet session uses a VT100/ANSI terminal type, and is
identical in look and feel to the Serial interface.
The web interface utilizes MD5 security. Some older versions of web browsers
may have problems with the higher level of security required for MD5
authentication. If problems with logging in are experienced, please download
the latest version or update the browser.
The following describes how to connect to the Dualcom S using a web browser:
1) Note the MAC address from the label on the Dualcom S unit.
2) Attach the unit to a network with a DHCP server using the Ethernet port
on the front of the Dualcom S unit. Power up unit and allow it to pick up
an IP address.
3) Once an IP address is selected, find the address in the DHCP table of
your DHCP server that corresponds to the unit’s MAC address.
4) In your browser, enter the IP address assigned by your DHCP server.
5) Log on using admin and password as the User Name and Password
(once other user accounts have been created, they can be used here as
well).

Setting High/Low Currents and Grace Periods
When the current rises above or falls below the current limit for longer than the
grace period, current alerts send syslogs and trigger SNMP traps. Do the
following to enable high/low current alerts and grace periods. Once enabled, a
log and a SNMP trap will be sent if the measured current drops below or rises
above the limit for longer than the low or high grace period.
1. To enable low current alerts, navigate to [ ] Enable Low Current
Alerts and press Enter. An xappears indicating the option is active.
Press Enter again to remove the x and disable the option.
2. To change the Low Current or Low Grace period times, navigate to the
desired setting and press Enter.

desired setting and press Enter.
6. Use Backspace and the number keys to change values. Press Enter
when done.
Enabling Cyber Breaker® the Virtual Circuit Breaker™
Cyber Breaker® the Virtual Circuit Breaker™ provides protection for each
individual outlet, so if one is pulling too much current, only that outlet is tripped.
It also eliminates uncertainties about when a circuit will trip.
Cyber Breaker® is not designed to protect against short circuits or major over
current conditions. If a circuit is shorted or if the bank/unit current is above the
rated limit, the primary or branch circuit breaker may still be tripped.
Selecting Enable Virtual Circuit Breaker trips the circuit if the current goes
over the number of amps set in the High Current (Amps) box for longer than
the number of milliseconds set in the High Grace Period box. The LED for that
outlet will then turn red, indicating the outlet is tripped. To reset Cyber
Breaker®, turn it off and then back on. The outlet will then turn on.
To enable Cyber Breaker®, navigate to [ ] Enable Virtual Circuit Breaker
(TM) and press Enter. An xappears indicating the option is active. Press Enter
again to remove the xand disable the option.
