1 Introduction
The PSM2001ACD 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, and a standard Modem interface. The PSM2001ACD provides a convenient
interface for users to develop various networking applications for intelligent devices. It
uses a standard Serial Peripheral Interface (SPI) communication port to connect to
the
user MCU and conforms to the MCUnet
TM
protocol. The PSM2001ACD connects to a
server gateway WebChipServer
TM
through any of the following: RS-232, RS-485 or
standard Modem.
2 Features
Single +5V power supply
Each module has a unique ID
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; 128 transceivers can be connected to the bus at
most.
—
Standard Modem mode: it provides an interface connection to the 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 the
MCUap protocol
Maximum operating current: 30mA
