The SDS has several indicator LEDs:
¾ Power (blue) – indicates when the SDS has line power
¾ Data (red/green) – indicates serial port data activity by blinking red for RS-232 or green for RS-422/485
¾ Status (green) – indicates when the embedded processor is up and running
¾ Link (green) – indicates when a network link has been established; located in the Ethernet connector
¾ Speed (amber) – differentiates between 100Base-T (glowing) and 10Base-T (off) Ethernet connection speeds; located in
the Ethernet connector
The DB-9 serial port(s) connect to your serial device(s) and can support RS-232, RS-422, or RS-485 connections. They are
located either to the left, to either side of the Ethernet port, or on the front panel, depending on the model.
The RJ-45 Ethernet jack connects the SDS to the Internet or to your Intranet. It has two small status LEDs: Link (green) and
Speed (amber).
The power jack should be connected to a +5V power source, as provided with the SDS.
The Reset button puts the SDS through a reset cycle and can also restore the SDS to the factory default settings.
The information label (not shown) is on the bottom of the SDS. It includes the following:
