This tab allows you to specify what type of data a particular port on the DL-V3 can transmit and
receive. Click directly in any of the cells and a drop down box of choices is available The receive type
(
Receiver
) tells the receiver what type of data to accept on the specified port. The transmit type
(
Transmitter
) tells the receiver what kind of data it can generate. For example, you would set the
receive type on a port to RTCA in order to accept RTCA differential corrections.
The
Ports
and
Interfaces
tabs are originally blank when the user creates a group (in case you don’t
want to alter the receiver ports and interface configurations when you start logging a group).
Otherwise the DL-V3 might drop the connection with
CDU
when the settings are changed.
Click on the
Add Defaults
button to add the default values for interfaces. To remove the values (for
example, so as not to interfere with
CDU
), click on the
Remove All
button.
You can set the base station ID, when it is transmitting corrections, in the
DGPS TX ID
field. The
following range values should be used when you are entering a base ID:
RTCA ID:
any four character string containing only alpha
(a through z) or numerical (0 - 9) characters
0
≤
RTCM ID
≤
1023
0
≤
CMR ID
≤
31
The default entry for the
DGPS Tx Id
field is ANY. The ANY option forces the message to revert to its
default base ID. The ANY defaults are:
RTCM
0
RTCA
AAAA
CMR
0
It is also possible to disable or enable the generation or transmission of command responses for a
particular port. Disabling of responses is important for applications where data is required in a specific
form and the introduction of extra bytes may cause problems, for example RTCA, RTCM or CMR.
Disabling a port prompt is also useful when the port is connected to a modem or other device that
responds with data the receiver does not recognize.
When NONE is chosen, the specified port is disabled from interpreting any input or output data.
Therefore, no commands or differential corrections are decoded by the specified port.
