7.6—SIO Module
7.6.1—Module Description
The SIO (Serial In/Out) Module interfaces four serial communication ports to the VME bus.
Figure 7-19 is a block diagram of the SIO module. The module manages four serial ports. Port a (J1) and
port B (J2) are RS-232 ports. Port C (J3) and Port D (J4) are for RS-232, RS-422, or RS-485
communication protocols. Ports C and D must be at the same baud rate when using 38.4 kBd or 57.6
kBd.
The processor on this module is a 68030. It controls the transfer of data between the ports and the VME
bus.
This module can have as much as 4 KB of Dual-Port RAM and 64 KB of PROM. The local memory
supports the 68030 processor on this module.
The SIO module has one LED (FAULT) and no switches.
