2 Change the SRD service request response timeout
value to 0 (zero). The default value is 60.
3 Click the Message tab, and then select the appropriate
SRD.
4 In the Test Commands group, select SRD RF On.
5 Cycle the SRD’s power.
SRD re-registers with the Management Control Centre.
The SRD is now set to the proper RF for calibrating the
SAM.
6 See “Calibrating the SAM” on page 4.

Note: After calibration is complete, the RF and SRD
service request response timeout values must be set back
to their original values.
Calibrating the SAM
After configuring an SRD for calibration, you can calibrate
the SAM. Calibrating the SAM is a two-person task in which
one installer trains the SAM using a transmitting SRD.
Another installer collects calibration data points at the Master
Management Centre (MMC).
To Calibrate a SAM
As an installer with the transmitting SRD moves around the
circumference of the SAM, the installer will stop at specific
increments (for example, every 20 meters) and the SRD will
automatically send a signal to the SAM. SAM collects the
data points to learn the SRD’s position.
Calibration data is collected at the MMC after identifying the
SAM Node ID. By specifying the Polar Coordinates (Angle
and Distance), each time a data point is identified (a signal
received from the transmitting SRD), you collect the
calibration data. After collecting the calibration data, you
clear one of the coordinates, usually the Y box, so that you
can collect another data point. The installer with the SRD
then moves, maintaining a fixed radial distance from the
SRD, and stops so that the MMC can collect another
calibration data point. This process is repeated until each
