Wireless Communication Overview

Since the early 1990s, wireless communication has been shifted from the first generation of
Advanced Mobile Phone System (AMPS) standard technology, to the 2nd generation technology
of digital cellular technology. The 2nd generation (2G) includes the CDMA and GSM
technology both have deployed heavily in North America and worldwide. Due to its digital
nature, the 2G technology has a much better utilization of bandwidth and can support a much
large number of users in the same given bandwidth when compare with the AMPS technology.
As such the wireless carrier service providers are beginning to stop the offering AMPS services
to their customers. Many of the equipments that were built with the analog modems and depend
on the AMPS services will have to seek other alternative.

The Telenetics solution is to build the Omega Digital series of wireless modem to operate in the
CDMA or GSM network environment and can interface, connect and convert the legacy
equipment with build-in analog modem, which previously can only operate in AMPS or PSTN
lines, to the head end host computer via the wireless cellular digital network.

The Telenetics Solution:

The product described in the document, refer to as the Omega Analog to Digital Converter
(OADC), is a standalone device that is to install at the remote site and connect the remote
terminal unit (RTU), utility meter, or end point device, internally equipped with an analog
modem, to the remote host computer by means of the cellular CDMA or GSM technology.
Typical network configuration of the OADC is listed in Figure 1.

The OADC is primarily designed to interface with a RTU or end point device equipped with an
internal voice band modem. The OADC consists of a motherboard and a daughter board. The
motherboard consists of the microprocessor and the peripheral components such as the flash
memory and data RAM. The daughter board consists of a modem data pump and the subscriber
line interface chip (SLIC). The primary function of the motherboard is to interface with the
cellular transceiver, the modem data pump and the SLIC within the daughter board. It also
controls and manages the data traffic to and from the daughter board. The primary function of
the daughter board is to interface with the analog modem within the meter, RTU or any end point
devices. The daughter board provides all the necessary voltages, ring signals and on-hook and
off-hook detection and control similar to a Telco central office.

If the daughter board is removed from the OADC, the Omega unit with only the motherboard is
capable of interface directly to an external DTE (RTU or end point device) with an RS-232 or
RS485 serial port interface.

Installation Procedure

1.   Obtain Cellular Service
     Contact your service provider to get a phone number. Once you have a phone number,
     program this number into the transceiver of Omega ADC.

2.   Set up the Omega’s Configuration

          a. Setting the DIP Switch to match you meter’s internal modem
                    SW1 and SW2 - Baud Rate Setting
                         - For Omega ADC, it is the receiving speed of analog modem.
                         - Baud Rate setting, see table 2-1
                         - The default setting of Omega ADC set to be auto mode. Both SW1
                             and SW2 are ON. In this mode, the analog modem can
                             automatically detect and use appropriate modulation and speed to
                             handshake with the internal modem of meter.
                    SW3 – OFF
                    SW4 - OFF.
                    SW5 – Diag/RSSI for LED indication. See section 4 of Chapter 2 for
                    SW6 – OFF.
                    SW7 – OFF.
                    SW8- Serial Port Communication (RS232/ RS485)
                         - For OADC, the baud rate of command port is fixed to be 9600 with
                             no flow control.

                        SW9 – 2W or 4W for RS485 full duplex communication.
                        SW10 – OFF (Set to ON for testing Mode).

5.   Test the Omega Unit

          a. Call the Omega ADC phone number for a modem connection
             Dial the Cellular phone number from the central computer to make a connection
             to the meter. After establishing the connection between central computer and
             meter, the bi-directional communication and data transfer is ready.

          b. Originate a data call from a modem connected to the Omega ADC
             Dial the phone number of central computer from the meter’s modem. The modem
             of meter is the originator of this phone call. Once modem of central computer
             answers the phone call, this connection will be established. The bi-directional
             communication data transfer is ready.

6.   Set Up Special Options for Your Applications

          a. Know the speed of the modem in you meter
             Due to non-standard modems, there may be necessary to change the SW1 and
             SW2 to match the speed of modem in your meter if the default baud rate setting
             cannot synchronize with your modem properly. For detail, please check 2.a
             section of Chapter 2.

          b. Set for a maximum online timer
             The default setting of online timer is 0 (never time out). This timer can be
             changed by the AT*T command.

          c. Set for a maximum register timer
             The default setting of register timer is 14400 seconds (4 hours). The timer can be
             changed by the AT*R command.

7.   AT Command Set
     You can issue the AT commands from the central computer or command port of Omega
     ADC. RS232/485 ports can be used for command port.

     AT*? – List the OADC commands.

     AT*D =[string] – set auto dialup phone number
     AT*D? – Display the auto dialup phone number
     Default: Empty

     AT*DEBUG = number

              0: disabled to display the debugging message
              1: enabled to display the debugging message
              2: directly connected to transceiver. The input/output will directly reroute to
              3: directly connected to modem. The input/output will directly reroute to modem.
               Note: 2 and 3 validated for local command port only.

    AT*ESC = <string> - Set the escape sequential string, maximum length is 9 characters.
    The default string will be “*+*+*+”. After issuing this AT command, OADC will enter the
    command mode. The commands can be issued from central computer, RTU or command
    ports. While in this command mode, the established wireless communication will NOT cut
    off until the central computer hangs up the call. In another word, hanging up the RTU will
    not cut off the communication.
