RIO
POWER SUPPLY
• Power-over-Ethernet (PoE)
A standard (802.3af) Power-over-Ethernet switch should be used to provide both power
and a network connection to the RIO using a single cable. Alternatively, if a PoE switch is
not available, a PoE midspan injector could be used.
The RIO operates as a PoE Class 1 device (0.44>3.84W) and will typically consume 1.5W.
GROUNDING
The RIO is designed to be mounted on a grounded (earthed) DIN-rail, no dedicated Chassis
ground (earth) terminal is provided.
The PoE connection (power and data) is completely isolated from all the RIO’s ports but the
ports are not isolated from each other (except relay outputs, RIO 44 and RIO 08 only).
STATUS LEDS
The ETC logo will illuminate when power is applied to the RIO. The red LEDs on the front of
the RIO indicate the unit's current status.
The Active LED flashes slowly once the boot up procedure has completed to indicate a fully
functional unit. Once the RIO has connected to a project running on a Controller, the Active
LED will light continuously.
The Ethernet LED indicates Mosaic-related network activity (not network link, see Ethernet
port later) while the remaining LEDs indicate communication on the various ports of the RIO.
ERROR CODES
Additionally the red status LEDs are used to indicate any boot failures of the RIO that prevent
the unit from operating. Error codes are displayed by a repeating pattern of flashing all four
LEDs a number of times in succession, followed by a 1 second pause:
1 flash - Invalid firmware version (reload firmware from Designer)
2 flashes - Invalid device type or serial number
3 flashes - Internal memory test error
4 flashes - Unable to perform factory restore due to corrupt factory firmware
5 flashes - Current firmware is corrupt, no valid firmware versions available to restore
6 flashes - Restored firmware is corrupt
Codes 2 through 6 indicate a hardware error; please consult your distributor, representative or
ETC support for assistance.
NOTE: Power must not be disconnected during firmware updates to the RIO as
corruption of the software may occur, perhaps even rendering the unit
inoperable.
