1 Introduction
The PSM2000ACD is one member of the WebChip
TM
family of products. The module
contains a network communication controller PS2000, an RS-232 transceiver, an RS-485
transceiver, an embedded Modem controller and a standard Modem interface. The
PSM2000ACD provides a convenient interface for users to develop applications for
various networking intelligent devices. It uses a standard Serial Peripheral Interface
(SPI) communication port to connect to the user’s MCU and conforms to the MCUnet
TM
protocol. The PSM2000ACD connects to a server gateway WebChipServer
TM
through
any of the following: RS-232, RS-485, embedded Modem or standard Modem.
2 Features
A single +5V power supply
Each module has a unique ID number
Supports multiple communication modes
—
RS-232 mode: the module has a built-in interface, a MAX232 (from MAXIM),
which performs the conversion between TTL/CMOS signals and RS-232 format.
—
RS-485 mode: the module has a built-in interface that features transient voltage
suppression and thermal shutdown; at most, 64 transceivers can be connected to the
bus.
—
Embedded Modem mode: the module has a built-in embedded Modem and DTMF
generation circuit that support both the standard V.22bis protocol and V.22
protocol.
—
Standard Modem mode: it provides an interface connection to a standard Modem.
Provides a standard SPI port that can be connected to various MCUs
Easy to design networking MCU application system
Supports any gateway software with MCUap
TM
protocol
Maximum operating current: 100mA in embedded Modem mode
