Description

Functional Description

The CEN-IO is an Ethernet interface device for VersiPort input/outputs and relay
closure outputs. It detects contact closure, digital and/or analog input/outputs and
provides dry contact closure outputs. All signals are monitored/controlled via
10BASE-T Ethernet using standard Internet protocols. The CEN-IO includes a
power pack (either a 500 mA pack for 120V AC or a 1000 mA pack for 220V AC
supply which is provided with the international configuration, CENI-IO).
The CEN-IO contains eight VersiPorts. These eight input/output connections are
referenced to a common ground. Each connection can act as either a digital output
(<o1> through <o8>), a digital input (<i1> through <i8>), or an analog input
(<ain1> through <ain8>). Pullup resistors may be turned on or off for each
input/output connection (<pullup1-dis> through <pullup8-dis>). The following
subsections make use of the reference diagram, shown below.
CEN-IO Reference Diagram
Operations Guide - DOC. 5718 Ethernet Input/Output Module: CEN-IO 1
Ethernet Input/Output Module Crestron CEN-IO
Digital Outputs: <01> through <08>
When a logic high signal is placed on <o1> through <o8>, the output pin is shorted to ground (switch S1-B in the reference diagram is closed). When a logic low signal is placed on <o1> through <o8>, the output pin is driven to +5V (switch S1-B in the reference diagram is open). This default behavior may be modified by placing a logic high signal on <pullup1-dis> through <pullup8-dis>. When the pullup resistor is disabled (switch S1-A in the reference diagram is open) and the corresponding <o> signal is driven low, the output pin floats. When the pullup resistor is enabled and the corresponding <o> signal is driven high, the output pin is shorted to ground.
Each signal <o1> through <o8> has a corresponding feedback <o1-f> through <o8­f> that is driven by the CEN-IO. Feedback is provided from the CEN-IO for these values since another non-Cresnet device on the network may talk directly to the CEN-IO and modify its values.
Example: <pullup1-dis> is driven high. When <o1> is logic low, versiport 1 is floating. When <o1> is driven high, versiport 1 is shorted to ground.
Example: <pullup1-dis> is driven low. When <o1> is logic low, verisport 1 is at +5V. When <o1> is driven high, versiport 1 is shorted to ground.
Digital Inputs: <i1> through <i8>
The CEN-IO can detect when one of its versiports is shorted to ground or driven by a 0 to 5 volt digital signal. When a pin is shorted to ground, the corresponding <i1> through <i8> signal is driven to logic high in the program. The threshold for detection is < +2.5V drives the signal in the program high. Note that for a contact closure input, the pullup resistor should be enabled for that particular input (this is the default behavior), else the input is floating.
Example: If versiport pin 5 is shorted to ground, <i5> is driven to a logic high level. When pin 5 is not tied to ground, <i5> is driven to a logic high level (as long as the pullup is left enabled, which is the default behavior).
Analog Inputs: <ain1> through <ain8> and Minimum Change <MinChange1> through <MinChange8>
A resistive sensor (for example, a sensor that measures humidity) or a voltage source may be tied to a vesiport. This sensor or source is represented by box "A" in the reference diagram.
When a resistive load is tied to a versiport, the corresponding pullup resistor must be enabled (default behavior). This creates a voltage divider and provides a varying voltage level (based on the current resistance of the sensor) for the CEN-IO to read. For example, if a resistive humidity sensor is tied to versiport 1, then <pullup1-dis> should be driven low. The corresponding level is read as an analog value on <ain1> and ranges from 0 to 65535.
When a voltage source is tied to a versiport, the corresponding pullup resistor should be disabled. This allows the A/D convertor in the CEN-IO to directly read the voltage source's value. For example, if a voltage source is tied to vesiport 1 then <pullup1-dis> should be driven high. The corresponding level is read as an analog value on <ain1> and ranges from 0 to 65535 (0 to +10V on the input pin).
The CEN-IO reports any change back to the program when an analog value changes. Depending on the input source, this can result in excessive traffic over the network. A minimum change value may be specified on a per-input basis. This tells the CEN­IO to wait until the corresponding analog input changes by the minimum value before reporting into the program. This is useful if an input source is not clean and has jitter.
2 Ethernet Input/Output Module: CEN-IO Operations Guide - DOC. 5718
Crestron CEN-IO Ethernet Input/Output Module
Example: A voltage source is placed on versiport 1. <MinChange1> is set to 10 via
an Analog Initialize symbol. The <ain1> input does not exhibit any change until it
actually changes by 10. If the currently reported value is 500, for example, a new
value is not reported until it changes to 510 or 490.
Each signal <MinChange1> through <MinChange8> has a corresponding feedback
<MinChange1-f> through <MinChange8-f> that is driven by the CEN-IO. Feedback
is provided from the CEN-IO for these values since another non-Cresnet device on
the network may talk directly to the CEN-IO and modify its values.
Relay Inputs: <relay1> through <relay8> and Relay Outputs:
<relay1-f> through <relay8-f>
The CEN-IO symbol definiton can control the eight relays on the CEN-IO and
obtain true feedback as to the state of the relays in the CEN-IO.
The inputs to the symbol <relay1> through <relay8> allow the SIMPL program to
turn the relays on and off. A high signal on any of these lines turns on the respective
relay. A low signal turns the relay off. For example, if <relay1> has a high signal,
then the relay turns on.
Since the relay states may be changed by a source outside of the Cresnet system, the
symbol outputs <relay1-f> through <relay8-f> allow the Cresnet system to monitor
the state of the relays in the CEN-IO. If an external source changes the state of the
relay to closed, then the respective line is driven high. If an external source changes
the state of the relay to open, then the respective line is driven low. For example, if
an outside source closes relay 2, <relay2-f> goes high.

Physical Description

The CEN-IO is housed in a black enclosure with silk-screened labels on the front
and rear panels. On the front of the unit there are 21 LEDs for indicating the unit’s
current status. All connections, except for one Ethernet port, are made on t he back
of the unit. Refer to the physical views shown on the next page. There are four
rubber feet on the base of the unit for stability and to prevent slippage when the unit
is stored on a surface or stacked. Up to two units can be rack mounted with an
optional 19.00 inch (48.26 cm) rack mount kit (sold separately).
