Special Modes 

 
 

The  special  modes  are  not  frequently  used  and  they  may  be  selected  by  pressing  the  “Select 
Function” push button  while simultaneously pressing a combination of multiple EDIT push buttons. 
The unit must be in the normal mode of operation to enter any of the special modes of operation. 
The table below shows the combination of the EDIT push buttons that need to be pressed to obtain 
the desired special mode.

1.   Addressing 

 
 

This special mode selection provides for programming the address of the unit used for computer 
control  through  the  RS-232  serial  communication.  The  unit’s  address  applies  to  all  3  channels 
(same address regardless of the channel selection). 

 
 

The unit determines its address at power up by using the following algorithm: 

 
 

1) 

VID: Address determined by ID voltage set in hardware  

 

2) 

MEM: Address stored in non-volatile memory 

 

3) 

READ VID 

 

4) 

IF VID = 0 THEN Address = MEM 

 

5) 

IF VID > 0 THEN Address = VID = MEM 

 
 

This special mode is selected by pressing the “Select Function” push button while simultaneously 
pressing  the  RIGHT  EDIT  push  button.  The  unit  returns  to  the  normal  mode  of  operation 
(Monitoring or Non-monitoring state) after pressing the “Select Function” push button one more 
time. 

 
 

When  this  special  mode  is  selected  the  first  "Function  LED"  will  be  blinking  and  the  serial 
communication baud rate for the unit will be shown on the LED display.  The baud rate can be 
modified by using the EDIT buttons.  An additional Press of the "Select Function" button will make 
the second "Function LED" blink and the address of the unit will be shown on the LED display.  
The address can be modified by using the EDIT buttons only if VID = 0.  The new address will be 
set and stored into the internal non-volatile memory when the unit returns to the normal mode of 
operation. 

 
 

2.  Error List 

 
 

This special mode selection allows the user to retrieve a listing of all of the errors that may be 
causing the failure LED to be ON.
