Intel iSBX 354 Dual Port Multimodule

The iSBX 354 module uses the Intel 82530 Serial
Communications Controller (SCC) component pro
viding two independent full duplex serial channels.
The 82530 is a multi-protocol data communications
peripheral designed to interface high speed commu
nications lines using Asynchronous, Byte-Synchro
nous and Bit-Synchronous protocols to Intel's micro
processor based board and system level products.
The mode of operation (Le. asynchronous or syn
chronous), data format, control character format,
and baud-rate generation are all under program con
trol. The 82530 SCC component can generate and
check CRC codes in any Synchronous mode and
can be programmed to check data integrity in vari
ous modes. The command lines, serial data lines,
and signal ground lines are brought out to a double
edge connector.
The iSBX 354 module provides a low cost means to
add two serial channels to iSBC@ boards with 8 or
16 bit MUL TIMODULE interfaces. In the factory de
fault configuration, the iSBX 354 module will support
two RS232C interfaces. With user supplied drivers
and termination resistors, the iSBX 354 module can
be reconfigured to support RS422A1449 communi
cation interfaces with support on Channel A only for
multidrop control from the base board. Both chan
nels can be configured as DTE or DCE with RS232C
interfaces.
