The JTHW multiplexer port provides eight inputs and eight outputs at TTL levels. While these I/O can be used

 

 

 

in unmultiplexed form for 16 discrete I/O points, most users will utilize PMAC software and accessories to use

 

 

 

this port in multiplexed form to greatly multiply the number of I/O that can be accessed on this port. In

 

 

 

multiplexed form, some of the SELn outputs are used to select which of the multiplexed I/O are to be accessed.
