NL5000 Serial Interface Cable
The above interface cable facilitates the connection of standard RS-232 signals to
a typical 9 pin “D” type female connector. This cable additionally accommodates
the connection of the +12 VDC, Ground and the A/B power or channel selector to
the 15 pin “D” type female connector on the NL5000 front panel. As shown, D1 is
placed in series between pin 6 and the + 12 VDC supply voltage and provides
reverse polarity protection.
