Polling

When the FELCOM receives a polling command from your home office it automatically
transmits data to your home office. The data are position, speed, bearing and other
data sent from a navigator or an interface unit.
A polling command from your home office can also activate a data report or message
report if the corresponding setting is completed on the FELCOM. If a polling command
with a file name is received, the FELCOM transmits the file to your home office.
6.2.1

Polling commands

This section shows you how to make the polling command at your home office.
There are two kinds of polling commands: one is sent on the MES signalling channel
and the other is sent on the MES message channel.
Polling command on the MES signalling channel
When a polling command is received from your home office, your vessel's coordinates
(position), bearing and speed can be sent automatically as a data report.
The available polling commands are:
• Send a report to the ship once only
• Send a report to the ship at regular intervals
(A program cycle report dependent on the polling command)
Note: The polling command differs according to land earth station. Contact the land
earth station directly for details.
Polling command on the MES message channel
To make the polling command, enter D???, hy-
phen, PIN code (max. 8 digits), hyphen, file name,
colon.
To send file data, type a hyphen and file name.
Then, only the file specified in the directory of the
Message Directory is transmitted. If neither hy-
phen nor file name is entered, nav data (own ship
position, course, speed, etc.) is transmitted.
How to register your PIN code
The PIN (Personal ID Number) code is a password used in message reporting, and is
an eight-digit number agreed upon by communicating parties. There is no rule for de-
termining PIN code. When a ship receives a polling command w/PIN code from a
shore subscriber and the code matches that of the ship, the ship sends a message
report.
