Crestron CEN-IO Ethernet Input/Output Module Ethernet Input/Output Module: CEN-IO 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.
Ethernet Input/Output Module Crestron CEN-IO Digital Outputs: <01> through <08> When a logic high signal is placed on through , the output pin is shorted to ground (switch S1-B in the reference diagram is closed). When a logic low signal is placed on through , 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 through .
Crestron CEN-IO Ethernet Input/Output Module Example: A voltage source is placed on versiport 1. is set to 10 via an Analog Initialize symbol. The 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 through has a corresponding feedback through that is driven by the CEN-IO.
Ethernet Input/Output Module Crestron CEN-IO CEN-IO Physical Views INPUT/OUTPUT RELAY OUTPUT CEN-IO Ports Most ports are provided on the back of the CEN-IO. Each has a silk-screened label. Refer to the illustration and descriptions below. There is only one port on the front panel of the CEN-IO. CEN-IO Ports (Rear Panel) INPUT/OUTPUT RELAY OUTPUT 12 VDC .5A This DC power socket connector is used to supply external power via the supplied 500 mA power pack (1000 mA power pack for CENI-IO configuration).
Crestron CEN-IO Ethernet Input/Output Module I/O (1 - 8, G) This 9-pin connector (eight input/outputs and one common) is used to detect digital and analog input/output levels. The contact closures to ground current is 2.5mA. Port recognizes input/outputs compatible with TTL and CMOS digital signals and can tolerate up to 24V DC. Threshold is 2.5V. Input/outputs can also measure analog voltages from 0 to 10V DC. RELAY OUTPUT (1 - 8) This 12-pin connector provides eight normally open relays.
Ethernet Input/Output Module Crestron CEN-IO ERR (Ethernet) This LED illuminates when an Ethernet protocol error is detected. RELAY (1 - 8) These LEDs illuminate when respective relay is closed. I/O (1 - 8) These LEDs illuminate when the input or output voltage threshold for respective INPUT ports are exceeded. Leading Specifications The table below provides a summary of leading specifications for the CEN-IO. Dimensions and weight are rounded to the nearest hundredth unit.

Doing so displays the MISCELLANEOUS SNMP INFORMATION MENU again. • Change the Assigned Name - Depressing “2” from the MISCELLANEOUS SNMP INFORMATION MENU instructs the program to reveal the current assigned name value and prompts the user to ‘Enter the new “Assigned Name”’.
Crestron CEN-IO Ethernet Input/Output Module master CRESNET ID and prompts the user to ‘Enter the entry number to remove’. Enter the entry number (1, 2, 3, 4, or 5). The program responds by prompting the user to ‘Press any key to continue’. Doing so displays the MANIPULATE MASTER LIST MENU again. Clear Dynamic Master List - Depressing “4” from the MANIPULATE MASTER LIST MENU removes all current entries from the dynamic master list. Press any key to return to the MANIPULATE MASTER LIST MENU.
Ethernet Input/Output Module Crestron CEN-IO the numbers consecutively. When all the numbers are entered, depress ‘9’ to return to the RELAY SELECTION MENU. VersiPort Control Depressing “3” from the MAIN MENU opens the VERSIPORT SELECTION MENU which appears on the screen as four options. VERSIPORT SELECTION MENU in Viewport Window Display All Inputs as Digital Depressing “1” from the VERSIPORT SELECTION MENU reveals the current digital state of the eight inputs (#1 through #8).
Crestron CEN-IO Ethernet Input/Output Module Restart Box Depressing “6” from the MAIN MENU allows the user to restart the device. The program responds with the ‘DO YOU REALLY WANT TO RESTART THE DEVICE?’ message. Depress ’Y’ to restart or ‘N’ to abort the restart. Depress any key to return to the MAIN MENU. Upload Firmware Depressing “7” from the MAIN MENU allows the user to upload the latest firmware via the Serial connection.
Ethernet Input/Output Module Crestron CEN-IO Block Diagram of System Incorporating a CEN-IO The touchpanel has an ON and OFF button for each zone (join number 1 and 2 for ZONE 1 and join numbers 3 and 4 for ZONE 2). Each zone has a light sensor that is connected to an analog input of the CEN-IO. The lights can be turned off either via a button press from the touchpanel or when the sensor detects a light level greater than 50% of its maximum value.

Crestron CEN-IO Ethernet Input/Output Module Glossary of Terms Community String Community strings are passwords that let an SNMP controlled device know the priviledge level of the controller with which it is communicating. There are seperate community strings for read only permission and read writer permission. Default Router Default router is the address of the router the device uses to communicate with devices that are not connected directly to the local network.
Ethernet Input/Output Module Crestron CEN-IO Master List Master list is a list of Crestron Internet Protocol (CIP) enabled devices that will be informed of any changes in the state of the controlled device. The device accepts commands from the addresses of these masters. NMS Trap Catcher NMS trap catcher is the address of a SNMP monitoring station that sends any alarm messages that the monitored device wishes to send.
