The table documents how UPS devices operate with the card. 

UPS:

UPS operational issue

Smart Serial: DB-9F smart signaling interface

Simple: Simple Signal interface via DB-9F

USB:

USB-B port on the card.

1 Simple Remote On

Not always supported. Some UPS devices 
allowed starting with the Remote On signal 
when AC utility power was off.

Remote On is enabled when AC utility power is on OR 
when AC power has been off for less than 10 minutes.

2 UPS

On button operation UPS turned on immediately.

UPS turns on after the configured Turn on Delay. The 
default setting is "0" (zero) - immediately turn on.

3 UPS

Switched Outlets

Were not supported.

Where relevant, switched outlet operation is disabled: all 
the UPS outlets function simultaneously. (The Main 
Outlet Group might turn on slightly before, and turn off 
slightly after, the other outlets). Switched outlet-related 
LCD menu screens are not accessible.

4 UPS

RJ-45 comms port

Was not supported.

Disabled.

5 UPS

USB comms port

Differed, depending on setup.

Disabled.

6 UPS

Self-test Operation Could always be initiated.

1. A self-test is enabled on extended-run UPS devices 
with more than 8 hours runtime. 2. A UPS might prevent 
a self-test if the battery charge is < 70%. 

7 UPS

Runtime Calibration A runtime calibration could be initiated, 

regardless of load and battery charge.

Two conditions must be met: 1. The battery charge must 
be 100%. 2. The load must be => 10% of the UPS rating.

8 Smart 

Serial

Test lights and 
beeper

The UPS beeped for 1.5 seconds

Beep operation is determined by the UPS; some newer 
UPS devices have a 5 second beep.

9 Smart 

Serial

Simulate Power 
Failure

The UPS operated momentarily on battery. The UPS does not go to battery operation, but 

temporarily remembers this command (in order to enable 
the Shutdown on Battery command).

10 Smart 

Serial

Establishment of 
Communications

Serial communications had to be re-
established each time the UPS turns on.

No change.

11 Smart 

Serial

Minimum battery 
capacity to restart

After a complete discharge of batteries in an 
outage, the UPS restarted when the battery 
charge reached this value.

The UPS reads the value as a %, and restarts as follows:
0%—an immediate restart; 15%—with runtime of 90 
secs.; 30%—with runtime of 180 secs.; up to a 
maximum 90%—restarts with runtime of 240 secs.

12 Smart 

Serial

Battery Replacement 
Date

Any 8 characters were supported.

The date format must be mm-dd-yy, with any separating 
character (“-” here) supported. Dates prior to the UPS 
manufacture date are not accepted.

13 Smart 

Serial

Alarm delay after 
line fail

On some UPS devices you could set the 
beeper to sound after being on battery for 30 
secs, or at low battery. All UPS devices 
could mute and disable the beeper.

UPS devices can enable, disable or mute the alarm. If 
beeping at low battery or on battery is selected, the alarm 
is disabled, but the setting is displayed on the LCD 
screen.

14 Smart 

Serial/
USB

UPS Model

Returned the device name, e.g. Smart-UPS 
750VA

Returns the closest equivalent historical name, which 
might be different from the name displayed on the LCD 
screen.

15 Smart 

Serial

Nominal Battery 
Voltage

Reported the nominal battery voltage of the 
UPS.

The nominal battery voltage is not known so the card 
“estimates” it and returns 024, 048, or 192; if an estimate 
is impossible, the card reports 024.

16 Smart 

Serial

Upper Transfer 
Voltage

For SURTD UPS devices, the card displays the 
corresponding bypass limit; but the allowable range of 
values is determined by the voltage setting of the UPS.

17 Smart 

Serial

Lower Transfer 
Voltage

18 USB

DelayBeforeReboot The Turn Off Delay setting was applied 

before turning the UPS off, the UPS 
remained off for the time specified, and was 
then turned back on immediately.

The Turn Off Delay setting is applied before the UPS is 
turned off, the UPS remains off for the time specified, 
and the Turn On Delay is applied before the UPS is 
turned back on.

19 USB

USB communication Not present on SURTD UPS devices.

Not functional when installed in a SURTD UPS device.
