Local control mode

Control of relay outputs based on TX IO input status

---

TX IO power supply

• 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

Access to the TX IO configuration server

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).

Selecting local control mode

Select the Local Control operating mode from the TX IO config tab . Once selected, restart your TX IO so that the mode change is taken into account using the Reboot button from the TX IO server Admin tab.

Configuring TX IO parameters from its server

In the CONFIG TX IO tab , configure your relays by selecting for each relay:

• Input: input 1 or input 2

• The relay mode: normally closed or normally open

Normally closed : corresponds to a closed rest state. When the status is 0, the relay is closed. When the status is 1, the relay is open.

Normally open : corresponds to an open rest state. When the status is 0, the relay is open. When the status is 1, the relay is closed.

• The delay: 1 sec, 5 sec, 10 sec, 30 sec, 60 sec or 120 sec.

Click Save to save your configuration.

Viewing the status of inputs and outputs

In the STATUS tab you can see the status display of the digital inputs and relays, as well as the number of status changes since power-up. You can test the status of the relays by clicking on the Toggle Relay button. The selected relay activates for one second. The TX IO is now configured, you can power it off.

Declaration and configuration of TX IO from the receiver server

The procedure declaration of the TX IO is the same as for other transmitters.

Activation of TX IO

Step 1

Power the TX IO (7.5 à 24VDC)

Open the TX IO case by unscrewing the 4 screws on the cover then supply your receiver externally (between 7.5 to 24VDC).

Step 2

Validate the TX IO LEDs behavior

Once your TX IO is powered and connected to your PC, you can validate the correct behavior of the product using its LEDs.

Validation of TX IO activation from the receiver server

In the CONFIG TX tab, refresh your browser page. 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.

In the NETWORK tab, the TX IO frames that you have just powered must be sent at the periodicity that has been configured. This tab allows you to validate the correct reception of the TX IO frames.

To decode the status of the TX IO inputs from the receiver's Modbus table, please refer to this article.

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.
