XYCOM XVME-400 70400-001 card

Overview

The Xycom Automation XVME-400 and XVME-401Quad Serial I/O Modules are single-high, single-wide VMEbus modules that provide a VMEbus system with four serial communication channels.  

The XVME-400 and XVME-401 differ only in their communication interface:  the XVME-400 provides four RS-232C serial ports, while the XVME-401 provides four RS-422A/RS-485 serial ports.

Both modules contain two Z8530 Serial Communica tion Controller (SCC) chips which provide a variety of communication modes, including asynchronous, byte synchronous, and bit-oriented protocols. 

Each channel is independently programmable and has its own baud rate generator and modem signal controls.

The VMEbus interface directly maps the Z8530 SCC chips into the short I/O address space, starting on a jumper-selected 1 Kbyte boundary. 

The modules can also be jumpered to generate an interrupt on any of the seven VMEbus interrupt levels.  

The two Z8530 SCC chips can generate a total of 16 different interrupt vectors.

For applications not allowing I/O to be routed out the front panel, the XVME-490 and XVME-491 offer the same functionality as the XVME-400 and XVME-401.

In a 6U form factor, the I/O is routed via the VMEbus P2 connector on the back of the board
