RIO Functional Elements
Microcomputer Section
The main processing unit of the RIO is a specialized 32-bit Freescale Microcomputer with 32KB SRAM and
256KB of Embedded Flash memory. The SRAM provides memory for variables, array elements and
application programs. The flash memory provides non-volatile storage of variables, programs, and arrays; it
also contains the RIO firmware. The RIO can process individual Galil Commands in approximately 40
microseconds.
The RIO product line has a maximum of 10,000 write cycles for burning (BN, BP, BV combined).
Communication
The communication interface with the RIO consists of one RS-232 port (default is 115 kBaud/s) and one
10/100Base-T Ethernet port (jumper configurable).
There are four status LEDs on the RIO that indicate operating and error conditions on the controller. Figure
1-1 shows a diagram of the LED bank followed by the description of the four lights.

Green Power LED (PWR)
- The green status LED indicates that the power has been applied
properly to the RIO.
Red Status/Error LED (ERR)
- The red error LED will flash on briefly at power up. After the
initial power up condition, the LED will illuminate for the following reasons:
1. The reset line on the controller is held low or is being affected by noise.
2. There is a failure on the controller and the processor is resetting itself.
3. There is a failure with the output IC that drives the error signal.
Green Link LED (LNK)
– The green LED indicates there is a valid Ethernet connection. This
LED will show that the physical Ethernet layer (the cable) is connected.
Activity (ACT)
– The amber LED indicates traffic across the Ethernet connection. This LED will
show both transmit and receive activity across the connection.
