Operator's Manual
Pulse Input Port 1 is pin 18 of the 31 pin connector and
Pulse Input Port 2 in pin 21 of the 31 pin connector. Both
ports share pin 14 as a common ground. These are separate
from NMEA-0183 Input Ports 1 and 2.
Pulses Pr.Nm - This is the calibrated pulses per speed unit value
that you must get from the speed log manufacturer.
Alarm If No Data - Causes an alarm to activate if data is not
received on the port you defined when Yes is selected (the
default condition). To disable the alarm, select No with the
Change softkey.
Correction Factor - allows you to make minor adjustments to
observed or measured errors in your speed through water
calculation. The input value will be multiplied by this value
before it is used in the receiver. The default value is 1.00.
Both input types have a window in the lower portion of the display
which indicates the input value in real time. If you are receiving
input data at the time you set the configuration up, you should see
the raw input value in the Input value, and the corrected value that
the receiver will apply in the Used value. 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.
