Communication controller card
SCC-04/TTL ACTIS Computer

The SCC-04/TTL module of ACTIS Computer S.A. is a 4-channel serial communication controller according to the VITA-4 specification. This module provides four asynchronous (up to 76.8 kbaud) and synchronous (up to 2 Mbaud) full-duplex channels, with an independent baud rate generator for each channel. The SCC-04/TTL supports TTL level serial interfaces.

The SCC-04/TTL module is based on two enhanced ESCC Z85230, with deeper FIFO and several SDLC improvement than the usual Z8530 Serial Communication Controllers (SCC) from Zilog.

An on-board 2 kByte EEPROM provides IP identification codes and module specific data. A complete industrial OS-9 environment is available for the SCC-04 module.
