SET  

Description 

Sets power load value in milliamps. If set too low, the minimum value 
will be set; if at or above 1400mA an error will occur. Note that this is 
the load for both the main and the alt pair. 

Command:   

set <value>

 

Response:   

printf(":p%d %dmA\r\n",port,value); 

 

or 

printf(":p%d %dmA (min)\r\n",port,value);

 

Example:   

g2 set 350 

Example response:  :

p9 350mA<CR><LF> 

:

p10 350mA<CR><LF> 

:

p11 350mA<CR><LF> 

:

p12 350mA<CR><LF> 

:

p12 350mA<CR><LF> 

:

p14 350mA<CR><LF> 

:

p15 350mA<CR><LF> 

:

p16 350mA<CR><LF> 

 

STATUS  

Description 

Returns the "Power Good" status of the IEEE load controllers. The 
power status is active when the IEEE controller is receiving power above 
the UVLO value and the load capacitor is charged. Also reports if an 
over temperature condition occurred that caused the port to be shut 
down. 

Command:   

st[atus]

 

Response: 

printf(":p%d PWR %d, PWR2 %d\n",port, state1, 
state2); 

state

 = 1 or 0 for on and off respectively. 

 

TEMPERATURE 

Description 

Reports the temperature of the drain pin of the MOSFET load, as 
measured on the line card PCB. 

Command:   

temp[erature]

 

Response:   

printf(":p%d %3d C\n", port, tempC);
