12.3.2.
Remote Data Retrieval
Environmental Satellite transmissions are one way transmissions. If the only radio that Satlink is
equipped with is the Environmental Satellite radio, there is not a way of retrieving data remotely.
The optional Iridium and Cell modules provide a means of remotely accessing Satlink.
12.3.2.1.
TCP/IP Connection
If Satlink has a cell modem module, a TCP/IP connection may be established using LinkComm.
Once the session is established, download Satlink’s log the same way you would as if you were
on-site.
12.3.2.2.
Messaging
If Satlink is equipped with the Iridium or the Cell module, it is possible to send Satlink a message
requesting the missing data. Please see the
12.3.2.3.
Repeat Tx Data
Repeat tx data requests may be used to get missing data from a Satlink. These requests may be
issued when directly connected to Satlink (via USB, RS232, Wi-Fi) and they may be issued
remotely (e.g. via Iridium). Satlink will reply to these requests by providing transmission data that
would have been transmitted at some point in the past.
In order to have Satlink repeat a transmission, apply the REPEAT option to the TXFORM
command along with a date/time of the missing transmission. Satlink will reply immediately with
the data.
Syntax: TXx TXFORM REPEAT YYYY/MM/DD HH:MM:SS
TXx may be any Tx (e.g. TX2, TX3)
YYYY/MM/DD HH:MM:SS is the date/time of the Tx data that needs to be provided
Here is a capture of the command line session:
!TX1 TXFORM RETX 2016/6/20 23:00:30
:BATT 0 #10 10.887 11.032 11.232 10.971 11.316 11.111 :TEMP 0 #10
28.25 28.25 28.00 28.25 27.75 27.50
Here is a usage scenario:
Customer is missing a GOES Tx that should have happened at 2016/6/20 23:00:30.
Customer sends an Iridium message with the syntax
!TX1 TXFORM REPEAT 2016/6/20 23:00:30
Satlink eventually replies via an Iridium message with
6:BATT 0 #10 10.887 11.032 11.232 10.971 11.316 11.111 :TEMP 0 #10 28.25 28.25
28.00 28.25 27.75 27.50
Please note that Satlink does NOT make a GOES transmission. It simply replies to the command
with tx data. In this example, Satlink was asked for data via Iridium, so it replied via Iridium. If it
had been asked via RS232, it would have replied via RS232.
