Interface Design Specification for the Sensor Communication Module Management Port

2.1 Overview

The SCM is a general purpose device for the collection and dissemination of sensor data.
It is comprised of built in sensors, external sensor interfaces, an RTLS radio, and a
microcontroller. It also has an LCD display, 3 push button switches, 3 LEDs, and a
buzzer that are user configurable. The SCM contains built-in temperature, humidity, and
contact closure sensors, and may optionally contain a GPS receiver. In addition, the
SCM has an external serial port that can be used to interface to other sensors. The serial
port also serves as the management port through which the SCM is placed into Manage
Mode as described by this document.

The SCM operates in either Run Mode or Manage Mode. Run Mode is the normal
mode of operation where the SCM collects data from the various sensors and either stores
it in NVM or transmits it via the RTLS radio. Data can be collected and transmitted at
timed intervals, or as specified by certain events. Events include threshold settings,
button presses, and external inputs.

The Manage Mode allows the user to define how the SCM will function during Run
Mode. Execution of Management Commands allows the user to tailor this behavior to
meet their specific operational needs. Manage Mode also provides for a Test

Command that causes the SCM to execute a built-in-test (BIT). Likewise, Management
Commands provide a means for the user to retrieve SCM configuration settings as well

as any data contained in nonvolatile memory (NVM). NVM data may hold data logged
from prior SCM utilization, or it may contain BIT results.

SCM Configuration Application Program (SCMCAP) is an automation of Management
Commands with built-in error checking. SCMCAP allows users to configure the SCM
for specific applications and uses.

3 SCMCAP Instructions

SCMCAP operates as a stand-alone Microsoft Windows PC application. Insert the SCM
software disk into the PC CDROM drive. It will automatically install. Follow the on­screen instructions during installation.

Connect an SCM to the PC’s serial port using the cable provided in the kit. Start the
SCMCAP program.

When launched, the SCMCAP Main Form will appear as shown in Figure 1. It contains
the following provisions:

a) Writing new configuration settings to the SCM
b) Setting Tag parameters
c) Defining user interface characteristics
d) Configuring the built-in sensors
e) Setting event-driven Actions
f) Reading the current configuration settings from an SCM
g) Retrieving SCM Nonvolatile memory
h) Testing the SCM
i) Placing the SCM in Run Mode

Placing the mouse pointer over a button or title will cause a definition of that field’s
function to be displayed.
