SP4000 Flow Computer

Initial Installation and Startup

When a SP4000 / TWP pair are first put on line, several
service actions are required. These include:
1.

Allow time for the SP4000 to charge the batteries in
the TWPNW (see note below)

Set up an account with Skytel and choose a suitable
service plan for this application

Initializing the Pager using the SP4000 INITIALIZE
PAGER utility

Registering the pager with Skytel using the SP4000
REGISTER PAGER utility

Observe a sample exchange of information between
the SP4000 and the remote user using the CLP
PROGRESS

NOTE: It is important to wait 24 hours for the Two Way

Pager Transceiver to charge its batteries prior to
initial use. Otherwise irradic problems may occur
during registration.

Special Utilities for steps 3, 4, and 5 are built into the
SP4000. These may be summarized as follows:

INITIALIZE PAGER = YES causes the SP4000 to send

commands to initialize the pager. The
responses to the command can be either
SUCCESS if all is well or FAILED if a
problem is detected.

to establish a connection with a local Skytel
tower. A series of informative messages
will appear as the SP4000 attempts to
register your PAGER PIN NUMBER with
Skytel. Note that your service plan must be
setup with Skytel before attempting to
register the pager.
The responses to the command can be
either SUCCESS if all is well or FAILED if a
problem is detected.

CLP PROGRESS is a diagnostic menu location that

provides information on the information
exchanges for test purposes (see CLP
Progress Menu in chapter 6). Contact the
applications group at SPONSLER if
problems are encountered in initial setup or
use of two way paging applications.

A more complex form of a remote metering system can be
implemented where the SP4000 will initiate a call to a
“mailbox” at Skytel. The Remote PC can access his mailbox
and read and process the various messages over the
internet as part of a customer billing system. Skytel offers a
software developers kit for customers wishing to create
custom solutions.

In each message, the SP4000 provides a header containing
information that can be used to determine such items as:
1. What is the TAG NO of the device that sent the

information?

2. What is its SENSOR SN
3. What is its DEVICE ID?
4. What type of message follows?
a. Exception Report (Message Type-1)
b. Send one Data Set (Message Type 2)
c. Send all new Datalog Data Sets (Message type 3)
5. What is the time and data of the first data record?
6. What information is contained in the data fields of CSV

that follow?

7. Message Delimiter (CRLF)
8. For commands returning data, the data now follows in

a CSV format

Consult the Universal Serial Commands User Manual for
details on the individual commands supported by the
SP4000.

Contact the SPONSLER Flow Applications Group for a
discussion on the remote metering system capabilities you
are considering.

RS-485 Serial Port (optional)

The RS-485 serial port can be used for accessing flow
rate, total, pressure, temperature, density and alarm status
information. The port can also be used for changing presets
and acknowledging alarms.
