Agile-Link™ Base Station manual which is contained on the Agile-Link™ CD and on
our web site for detailed instructions on its use with SG-Link® OEM .
The SG-Link® OEM has an additional datalogging feature which we describe as
Sensor
Event Driven Trigger (SEDT)
. In SEDT, the SG-Link® OEM may be configured to
commence datalogging automatically each time a “ceiling” or “floor” sensor output is
met. For example, you may set the SG-Link® OEM so that a datalogging session is
triggered whenever channel 1 (the differential input channel) exceeds (goes through the
ceiling of) 40 microstrain. The session will begin automatically, run its finite duration
and stop. With the next 40 microstrain ceiling event, the SG-Link® OEM would again
run a datalogging session automatically without manual intervention.
When the SG-Link® OEM is not sampling, it can be in one of two states: Sleep or idle.
In Sleep mode, the SG-Link® OEM, on a settable interval (by default 5 seconds),
momentarily awakens and listens for any commands. If a command is heard, it wakes and
responds to the command; if no command is heard, it goes back to sleep. This sleep
function is used to conserve battery power. In idle mode, the SG-Link® OEM is awake
and listening for commands from a base station.
Several configuration/operational/test functions exist for the SG-Link® OEM; some of
the more often used functions are listed below.
•
A
Verify
will test whether the base station and software are communicating
successfully.
•
A
Ping
will test whether a single byte transmission from the base station to the
node is successful.
•
A
Range Test
will test whether communication is being maintained over a period
of time between the base station and the node.
•
A
Cycle Power
will have the effect of manually cycling the power on the node.
•
Node Discovery
allows the base station to detect any node on any frequency as it
is powered on.
•
Load Node Information
reads and displays the model, serial number, firmware
version and other statistics of the node.
•
Frequency
allows reading and setting of the channel on which the node is
operating.
•
Read/Write EEPROM
allows direct reading and setting of parameters
maintained in EEPROM.

accessible features of the SG-Link® OEM.
