What are Packets?
Packets are chunks of data forwarded to the data host at a given interval. The GEM provides various
packet formats to accommodate various hosting sites and software. The packets are sent to both, Com1
(primary) and Com2 (secondary) ports.
REAL-TIME ON-OFF
Refer to Figure 20. The “ON” and “OFF” radio buttons (1) are used to enable/disable the transmission of
the packets. When set to “OFF” a “Keep-Alive” string is sent. This is used to keep a TCP-IP connection
when the GEM is configured as a client. This may be modified in the “Advanced” menu section.
When the page is loaded, the “Real Time Status” button (1) will indicate the current status.

PACKET FORMAT
The packet format is the structure and syntax of the packet. The format varies based on the
requirements and specification defined by the device or site that will be hosting the data. The “drop
down” box provides many different options.
