The JTHW multiplexer port provides 8 inputs and 8 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.

The direction of the input and output lines on this connector are set by jumpers E7 and E8. If E7 is removed or E8 is installed then the multiplexing feature if the JTHW port cannot be used.
