5A. RS232 Communication Mode

Your UPS is set to this mode when you receive it. If you decide not to use the AS/400
UPS monitoring software, you can use this mode to issue commands to the UPS and to
display UPS settings and power conditions. If you would like more information on two-
way communication, commands, and UPS settings, 

call Best Power

 to request document

FTS 502. When the UPS is in the RS232 communication mode, the pins at the DB9 com-
munication port perform these functions:

Pin 1: RS232 Receive Data. Receives incoming RS232 communication data.
Pin 2: RS232 Transmit Data. Sends outgoing RS232 communication data.
Pin 3: Normally Open On Battery Contact. A normally open contact that closes 15

seconds after the UPS switches to battery power.

Pin 4: Common. The signal ground for all signal pins.
Pin 5: Normally Open Low Battery Alarm Contact. A normally open contact

that closes during a Low Battery, Near Low Battery, or Low Runtime
alarm. This tells the AS/400 UPS monitoring software when to start a
computer shutdown. (You can enable this contact for other alarms; for
more information, 

call Best Power 

for document FTS 502.)

Pin 6: Plug and Play Sense for Windows 95.
Pin 7: Remote Shutdown. Shorting this pin to common turns the UPS off.
Pin 8: Unreg12 V isolated source.
Pin 9: Not Used.

Contacts consist of open collector circuits capable of switching up to +40 VDC 50 mA
resistive load. 

5B. Extended Signal Communication Mode

In this mode, additional signal contacts are available for Remote Shutdown and On
Battery Status on pins 1 and 2; pins 3-9 have the same functions they have in RS232
Communication mode. Two-way communication is not possible in Extended Signal mode
— you cannot send commands or display or change parameters.

Pin 1: Remote Shutdown. If the UPS is using battery power and a +12-volt DC sig-

nal is applied to this pin for 5 seconds, the UPS will shut down 30 seconds
later. When the power outage ends, the UPS will automatically restart. Signal
and shutdown times and automatic restart are programmable; for more infor-
mation, 

call Best Power

 for document FTS 502.

Pin 2: On Battery Status. When the UPS is using battery power, this pin produces a

+12-volt DC (RS232-level) signal.

5C. Changing Communication Modes

Note: Since you can use either mode with the AS/400 UPS monitoring software, you do

not need to change the communication mode for standard AS/400 operation.

1.   Find the DIP switches on the back of the UPS (see the 

drawings below

); then, find

DIP switch 4.
