RS232 Communications Protocol & Command Set (continued)

Non Critical Load Outlets On

This command controls the relay that feeds power to the NCL Outlets. Note that if the MAIN relay is off, the outlets will still be un-energized.

Send to UPS:

NCL_ON<CR>

Action:

NCL relay closes.

Response from UPS:

NCL_OUTLETS_ON<CR> (if MAIN

 

relay is ON)

 

NCL_OUTLETS_OFF<CR> (if MAIN

 

relay is OFF)

Non Critical Outlets Off

 

NCL_OFF<CR>

Send to UPS:

Action:

NCL relay opens.

Response from UPS:

NCL_OUTLETS_OFF<CR>

Set Low Battery NCL (Non-Critical Load) Shutoff

It is desirable to allow the user to set the battery storage threshold in which the non-critical load outlets will shut off therefore reserving the remaining battery charge for the critical equipment. If the battery charge falls below the threshold, Non Critical Load Outlets are turned OFF.

A common example of critical equipment would be a projector. It is critical that power be maintained to a projector to allow its fan to run and cool the bulb. If the bulb is allowed to overheat, it will be damaged and is very expensive to replace.

Send to UPS:

BATTHRESH<SP>XX<CR>

 

<SP> represents a space: 20 Hex

 

XX is a number between 25 and 60

 

represented in ASCII.

If XX is a valid number, between 25 and 60:

Action:Assigns the battery threshold variable with the value XX

Response from UPS:

BTHRESH<SP>XX<CR>

If XX is not valid:

 

Action:

None

Response from UPS:

INVALIDCMD<CR>

Enable Audible Alarm

It is important that the UPS be as quiet as possible as it will be located in a home theater environment. It is desirable to control the warning beeper. The default setting for the alarm is OFF.

Send to UPS:

BEEPON<CR>

Action:

The beeper will sound when running

 

 

from battery.

Response from UPS:

BEEPISON<CR>

Disable Warning Beeper

 

 

Send to UPS:

BEEPOFF<CR>

Action:

The beeper will not sound when running

 

 

from battery.

Response from UPS:

BEEPISOFF<CR>

Restore Default Settings

 

RESTORE<CR>

Send to UPS:

Action:

Set Non-critical load threshold (2.5)

 

 

to 66%

 

 

Disable the warning beeper (2.7)

 

 

Set High Voltage Failure Threshold to

 

 

147V (2.8)

 

 

Set Low Voltage Failure Threshold to

 

 

88V (2.9)

 

 

Set Battery Mode Voltage to 120V (2.10)

Response from UPS:

DEFAULTSRESTORED<CR>

QUERIES

Request Outlet Status

Transmit the ON/OFF status of the outlet banks.

Send to UPS:

?OUTLETSTAT<CR>

If NCL Outlets are ON:

 

Response from UPS:

NCL_OUTLETS_ON<CR>

If NCL Outlets are OFF:

 

Response from UPS:

NCL_OUTLETS_OFF<CR>

If CL Outlets are ON:

 

Response from UPS:

CL_OUTLETS_ON<CR>

If CL Outlets are OFF:

 

Response from UPS:

CL_OUTLETS_OFF<CR>
