5.4 Status Output
The status output is an option that reports Analyzer conditions via contact closures on the rear
panel. The closures are available on a 50 pin connector on the rear panel. The contacts are NPN
transistors which can pass 50 ma of direct current. The pin assignments are listed in Table 5-9.
