1.6 7188EX, 7188EA & 7188EN Series
I-7188EX is powered by an 80188-40 processor with 512K bytes of static
RAM, and 512K bytes of Flash memory. One serial RS-232 port and one RS-
485 port are provided. Ethernet support is provided by a NE-2000 compatible
controller with 16K bytes of on-chip buffer memory and 10Base-T media
interface. The I-7188EX also provides 14 user defined I/O pins. A cost-
effective I/O expansion board with A/D, D/A, relays drivers and protected
inputs is available. The I-7188EX also supports battery back-up SRAM boards
and Flash-Rom boards, providing non-volatile mass storage from 128K bytes
megabytes to 64 megabytes. The 10BASE-T port is equipped with a RJ-45
connector. The 10BASE-T interface supports a maximum of 100 meters
cable(22 AWG to 26 AWG) length between the I-7188EX and network hubs.
Compared to the I-7188EX, the I-7188EA adds seven open-collector output
channels and six digital Input channels. The I/O Expansion bus has been
occupied by a DI/O expansion board.
The I-7188EX, an Embedded Internet/Ethernet Controller, focuses on
embedded control applications while the I-7188EN, an Internet
Communication Controller, focuses on communication applications.
Depending on different embedded firmware programs, the Internet
Communication Controller can be used as either one Device Server, one
Addressable Ethernet to RS-232/485/422 Converter, or one Embedded
Internet/Ethernet Controller. Users should refer to comparison table to choose
optimal product. Currently, we offer a wide range of Internet Communication
Controllers, such as I-7188E1/E2/E3/E4/E5/E8. Except the RTC circuitry, the
basic hardware of I-7188EN is similar to I-7188EX. Since there are too many
Configurations for the I-7188EN series product, an OEM or ODM version is
welcomed.
