Optional Interface Kits: For computer systems that already have UPS monitoring software, Best
Power offers interface cable kits for connecting the FERRUPS to your
computer system. The kit includes the cable, adapters, and instructions.
Optional Internal Bestlink™
SNMP/Web Adapter: Using Simple Network Management Protocol (SNMP), system
administrators can easily monitor and manage remote UPS units that protect
key network devices like servers, routers, and hubs. Best Power’s SNMP
Adapters provide a self-contained link between the FERRUPS and an
Ethernet or Token Ring LAN/WAN. The adapters allow the system
administrator to communicate with the FERRUPS even after the protected
device goes down. The SNMP adapter displays over 60 Management
Information Base (MIB) variables to give the system administrator
information about UPS operation.
BestDock™ FERRUPS has a communication slot that allows quick installation of an optional
SNMP card.
Emergency Power
Off (EPO): You can connect your FERRUPS to your Emergency Shutdown switch to provide a
method for emergency FERRUPS shutdown. This connection shuts down the
FERRUPS output. See the Installation Manual to make the connection.
702 DB9 Port Pin Functions
The table below explains the functions of the pins on the FERRUPS’ DB9 port. This port is on the
FERRUPS’ back panel. The functions of pins 1 and 2 change depending on the communication mode.
When you receive the UPS, it is set up for RS232 mode. However, if you want to use the alternate
functions of pins 1 and 2, you can change the mode by following the steps on the next page.
Pin Function
1 In RS232 mode, this pin receives incoming RS232 communication data.
In Extended Contact Mode, this pin can cause a remote shutdown. If the UPS is using battery power and a
+12-volt DC signal is applied to this pin for 5 seconds, the UPS will shut down 20 seconds later. When the
power outage ends, the UPS will automatically restart after 15 seconds. Signal and shutdown times and
automatic restart are programmable; for more information, call the nearest Best Power office.
2 In RS232 mode, this pin sends outgoing RS232 communication data.
In Extended Signal mode, this pin indicates Inverter (On Battery) Status. When the UPS is using battery
power, this pin produces a +12 VDC signal. When the UPS is not using battery power, this pin produces a -12
VDC signal.
3 Normally Open On Battery Contact. This is a normally open contact that closes (pulls to Common) 15 seconds
after the UPS switches to battery power.
4 Common. This is the signal ground for all signal pins.
5 Normally Open Low Battery Alarm Contact. A normally open contact that closes (pulls to Common)
during a Low Battery or Low Runtime alarm. The FERRUPS can be programmed to close this contact during
other alarms. See the item 5 3 5 in the menu 5 3 System Mode Control.
6 PnP Sense. This pin senses the Microsoft Plug and Play (PnP) request from the PC.
7 Remote Shutdown. If this pin is shorted to common for at least 5 seconds while the UPS is operating on
battery power, the UPS shuts down after 120 seconds (2 minutes).
8 Normally Closed On Battery Contact. A normally closed contact that opens (releases from Common) 15
seconds after the UPS switches to battery power.
9 Normally Open Bypass Switch Status Contact. A normally open contact that closes (pulls to Common)
whenever the UPS is being bypassed through a bypass switch.
