The following configuration parameters are available as outlined in Table
9 below.
Table 9: PPNM output setup parameters
The 961’s PPNM default settings are 200 ppnm, 100 milliseconds, and
200 milliseconds.
To change the PPNM settings:
1. Press the CURSOR PAD down to highlight PULSES PER NAUTICAL
MILE, PULSE TIME MINIMUM, or PULSE SEPARATION MINIMUM, then
press the EDIT key.
2. Enter the desired parameters, then press the ACCEPT key (or press
CANCEL to leave the option unchanged).
Using VGA output
The 961XD supports an external VGA monitor output from the female
15-pin standard VGA video connector located on the back of the proces-
sor (See Figure 14 on page 21). Conversion of the signal to an NTSC or
PAL video output is possible using VGA converters. Use a VGA-to-NTSC/
PAL converter that doesn’t require separate software. This should be
plug-and-play hardware for standard VGA video input conversion, sup-
porting frame buffering at 75-Hz refresh rate. Also, consider the require-
ments for power: A unit requiring a DC power source is less likely to
cause interference.
