Using the concept of the SIMM (Single Inline Multipurpose Module), the
SIO-1 features three RS232 serial channels and one RS485 'two-wire' channel.
The SIO-2 features four RS232 serial channels. This makes the SIO-1/-2 ideal
in applications requiring additional serial channels at low cost and/or less
The module can be used on any microprocessor board providing the local MLX bus-extension. The MLX-bus (MPL local extension) provides an 8-bit synchronous bus and can be used like any microprocessor peripheral. The dimensions of the board are very small and the connector is an AMP-standard SIMM-connector.
The technology used is fully CMOS and low power consumption of typically 18mA at only +5V is achieved.
