NorthStar Navigation 961XD installation manual Using VGA output, Ppnm output setup parameters

SECTION THREE - Interfacing

The following configuration parameters are available as outlined in Table 9 below.

Table 9: PPNM output setup parameters

Parameter	Options
Pulses per nautical mile	Enter 1 to 999 pulses
Pulse time minimum	Enter 1 to 999 milliseconds
Pulse separation time	Enter 1 to 999 milliseconds

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.
