Correction Factor - Allows you to make minor adjust-
ments to observed or measured errors in your speed
through water calculation. The input value will be multi-
plied by this value before it is used in the receiver. The
default value is 1.00.
Digital Pulse Input:
Pulses Pr. Nm - This is the calibrated pulses per speed
unit value that you must get from the speed log manu-
facturer.
Alarm If No Data - Causes an alarm to activate if data is
not received on the port you defined when Yes is select-

Both input types have a window in the lower portion of
the display which indicates the input value in real time.
If you input a calibrated pulse rate, you can check for the
appropriate speed right here.
You will be able to view the speed log information in the
NAV4 screen when it is implemented in future software.
Log Pulses - GPS SOG Log Pulse Output
This screen controls the output port (Pulse) of the
speed over ground log output from the MX500 CDU at a
user-defined pulse rate per nautical mile. This output is
normally used to feed GPS SOG to an ARPA radar. The
default state is not active, and set to 200 pulses per
nautical mile.
