7.6 Hello command
This command establishes communication with a new unit. An example of communication
with SDI-EO and SDI-OE is shown in the following. The command is short (a single
question mark) to save bandwidth. The card will respond with card info. If the card is not
present, the command times out.
A typical response would be:
0409?
0904EO/SDI/1310nm,-7.5dBm\
hw rev 1.0\
sw rev 1.0\
protocol ver 1.0
This is an electrical to optical converter for SDI, with a -7.5dBm 1310nm laser. The
hardware revision is ver 1.0, and the software version is ver 1.0. The protocol version is 1.0.

7.7.1 Hello command
An EO converter will respond to a hello command with:
0409?
0904EO/SDI/1310nm,-7.5dBm\
hw rev 1.0\
sw rev 1.0\
protocol ver 1.0
or
0409?
0904EO/T140/1310nm,-7.5dBm\
hw rev 1.0\
sw rev 1.0\
protocol ver 1.0
7.7.2 Info command
The card will respond to the command string "info" by sending the card status. This is a
typical example.
