The TX IO declaration procedure is the same as for other transmitters. Please visit the sectionConfiguring sensors
Step 2 : TX IO Activation
Once declared on the receiver server and configured, you will need to activate the TX IO to pair it with the receiver. Below are the steps for activating the TX IO.
Power the TX IO (7.5 - 24VDC)
Open the TX IO case by unscrewing the 4 cover screws.
Externally power your TX IO (between 7.5 and 24VDC). If you use our 12V power supply, connect your power supply to the POWER terminal of the receiver.
•Red wire connected to the V+ terminal block
•Black wire connected to the 0V terminal block
Validate the TX IO LED behavior
Once your TX IO is powered and connected to your PC, you can validate the correct behavior of the product using its LEDs. LEDs behavior
Step 3 :Validation of TX IO activation
Validate that the TX IO communicates with the receiver.
From CONFIG TX tab
In the CONFIG TX tab, refresh the page in your browser. A validation sticker should appear in front of the TX IO that you have just activated.
A red dot means that the configuration is being recovered. Do not hesitate to wait a few moments and refresh your page if the green dot does not appear.
From Network tab
In the NETWORKtab, the TX IO frames that you have just activated must be sent at the periodicity that has been configured. This tab allows you to validate the correct reception of the TX IO frames.
Step 4 : Relay control
From a RX MODBUS
The relays are controlled by writing to the Status registers of the relays from the Modbus table. For example, you can activate relay 1 by changing the value of the corresponding status register (0 = OFF / 1 = ON).
From a RX BACNET
Relays are controlled by writing to the Relay Status objects. For example, you can activate relay 1 by changing the value of the corresponding status object (0 = OFF / 1 = ON).
The minimum delay between sending two commands to the TX IO is 2 seconds. If you send a second command before this 2 second delay, it will not be taken into account by the TX IO.
To decode the status of the TX IO inputs from the receiver's Modbus table, please refer to this article.
Optional step: Displaying the status of inputs/outputs
The procedure for accessing the TX IO configuration server is identical to that of the receiver. The default address for accessing the TX IO server is 192.168.77.77 (please avoid use on Microsoft Edge and favor use on Google Chrome).
In the STATUS tab you can see the status display of the digital inputs and the counts since power-up. At the bottom of the tab you can see the relay status display ON or OFF and the number of times the status has been switched from the TX IO power supply.
You can test the relay status by clicking the Toggle Relay button. The relay activates for one second.
The TX IO relays are contact type, electronic mosfet relays without polarity. The maximum voltage between the two relay terminals is 48 VDC and the maximum current is 500 mA.
