SL3-SDI-1
The figure below shows the connections provided by the SL3-SDI-1. A description of each of the
connections is provided in the following paragraphs.
3.3.
SL3-XMTR-1
SL3-XMTR-1 is similar to the SL3-SDI-1 with the following changes:
The 2 SDI-12 ports are replaced with an auxiliary DB9 connector. This connector is for
factory use only.
There is no Wi-Fi module in the SL3-XMTR-1. The button will not turn on Wi-Fi but is
only for failsafe reset.
SL3-XMTR-1 is designed to connect to another logger via the RS232 port. The logger will
setup the SL3-XMTR-1 and regularly transfer data to it for transmission. The logger may
use Sutron’s Satlink Communicator Protocol (SCP) or command line protocol for setup
and data transfer functions.
Contact Sutron customer service for additional information.
3.4.
Multi-function Button
Satlink3 has a multi-function button installed on the front.
Briefly pressing this button will turn on the Wi-Fi.
Additionally, if the failsafe has been tripped, briefly pressing this button will reset the
failsafe.
The multi-function button is also used to reboot Satlink. If the button is held down for 5
seconds, the red LED will come on. Keep holding the button until the red LED turns off
in order to reboot Satlink.
