5.2 Optoisolated Rear I/O Module
The CP-RIO3-46-OPT rear I/O module is a 4-channel serial I/O device supporting the RS485
industry standard. The serial I/O channels of this module are optoisolated. The CP-RIO3-46-
OPT is provided with the following key features.
• up to 115.2 kBaud asynchronous transmission
• 4 serial channels
• 50-pin, dual row, female, D-Sub connector (all channels on one connector)
• RS485 standard (without local echo)
• 1kV process-to-system side optoisolation
• bus termination resistors, hardware selectable
• control LEDs both on the module’s and mainboard’s front panels
• Windows® 2000, Windows® XP, Windows® XP Embedded, Linux® and VxWorks®
drivers
The supply voltage for the module is 5V DC. It is provided by two 5V/5V on-board DC/DC
converters, one for the channels 0/1 and one for channels 2/3.
Warning!
The power signals (+5V and GND) are power supply INPUTS to supply the rear
I/O module with power. These pins MUST NOT be connected to any other
power source, either within the backplane itself or within the rear I/O module.
Failure to comply with the above will result in damage to the CPU board, and
can result in damage to the RIO module.
In addition, all pins that are reserved or N/C must not be used for any other pur-
poses.
