Technical Description 

Page 6 

 

 
Ten pin bussed resistor packs are installed to provide pull-ups to the input ports. These are 
installed on all ports. The pull-up resistor packs are rated at 10K ohms. Figure 2 below provides the 
bussed resistor and corresponding port. The resistors insure that no line is floating which is not 
connected. This provides consistent biasing on all un-terminated lines.
