INTRODUCTION
Direct machine-to-machine interaction represents the
next logical extension of the internet. Cermetek internet
modem (iModem) products are designed to exploit the
internet to facilitate the utilization of machine-to-
machine interactions. Using email, information can
easily be transferred between systems and can be
transmitted/retrieved at will. Internet email provides low
cost, near real time multi-path communication.
Replacing conventional modems and long distance
telephone lines with local access internet connections
reduces fixed asset and maintenance costs, limits
communication expenses and saves money.
USER FRIENDLY INTERFACE LAYER
All Cermetek iModem products contain a user friendly
interface layer that provides the user transparent
access to the internet. This interface layer, consisting
of various
@T
®
macro commands, has the look and feel
of conventional modem AT commands. With the
@T
®
macro commands the user can direct the iModem to
compose, edit/modify, send, retrieve and delete email
messages. Internet and email activity status is reported
via the iModem’s V.24 (EIA 232-E) serial interface.
The CH2124/60 products are the first generation
internet enabled devices. These products excel at
sending and retrieving modest amounts of data. Email
messages of approximately 125 ASCII characters in
length can be stored in internal Flash ROM for later
transmission. Emails of larger length can be retrieved.
The CH2124/60 products are ideal for very low cost
controller applications and in applications where limited
data transfer is required.
OVERVIEW OF THE CH21XX iMODEM
A conceptual representation of the iModem in an
embedded environment is presented in Figure 1. As
can be seen in this figure, the iModem requires the
input of various internet parameters to function properly:
user name, user ID, user password, ISP telephone
number, ISP mail server address/name, local email
address/name, destination email address and user
specified email message/input port status.
