The node card has two jumper links fitted, J1 and J2, these are illustrated in figure 4.1 below which shows a 
section of the node card. The configuration of these should be set when the shelf is installed using the 
information table 5.1 below. 
 
 

J1 

Post mate enable 

Rectifiers run with no additional connections 

PL5 pin 19 must be connected to PL5 pin 15 
for the rectifiers to run. Can be used as 
remote inhibit function. 

J2 Signal 

ground 

Signals common (PL6 pin 6, PL5 pin 10) is 
connected to negative sense (PL6 pin 12, 
PL5 pin 15). 

Signals common isolated from negative 
sense. 

Table 5.1 

 
 

Potentiometer P1 on the node card adjusts the output voltage of all the rectifiers simultaneously, its position is 
illustrated in figure 5.1 below. It is also adjustable through a hole in the shelf rear panel. The Vtrim signal being 
fed to the rectifiers can be measured on TP1 (TP2 is 0V). An input of 5.0V results in no adjustment of the rectifier 
voltages.
