This one isn&#8217;t too sexy, but is a necessary part &#8212; a pulse-per-second (&#8220;PPS&#8221;) distribution system.  This enclosure contains 4 TADD-3 PPS distribution boards.  Each board has 2 sets of 3 outputs, plus 2 RS-232 level outputs.  So, there are 8 input connectors on the rear, as well as 4 DE9 connectors (the PPS signal is on the DCD line, and I&#8217;m only bringing out the RS-232 signal from the &#8220;A&#8221; side of each board).
