Association procedure

The basic function of the e.sylink is that it can be connected by means of a wireless interface 802.15.4, equipped with a protocol owned by DAB, to one or more e.sybox units.

It is possible to connect the e.sylink to an e.sybox or to several e.sybox units using the following procedure:

• Supply power to the e.sylink
- Go to page AS (see e.sybox manual) on the e.sybox, press the '+' key for at least 5 seconds, wait for the blue leds (on the e.sybox display) to blink every 2 seconds.
- Press the right key on the e.sylink for at least 5 seconds, then wait until the system 1 blue leds (see table 4) is lit with a fixed light.

To interrupt the procedure it is possible to press the left key on the e.sylink. In the event of a momentary disconnection from e.sybox, the blue led blinks to indicate that the device is not connected, but is trying to restore the connection.

The wireless network configuration is maintained even in the case of a temporary power cut or if the device is switched off.

Disconnection procedure and resetting of the wireless configuration. Hold down the left key for 5 seconds. If the operation has been successful the System 1 blue leds will be off.

4 - HOW TO UPDATE E.SYLINK AND E.SYBOX

e.sylink has the possibility of updating its firmware through a USB connection and of updating e.sybox firmware by means of a wireless connection. When the e.sylink is connected to the PC using the USB cable provided, a .bin file can be seen in it which contains the e.sylink firmware and the firmware for updating the e.sybox. The file will be of the type EsyBox_Vxxx.yy_EsyLink_Vkkk.zz.bin, where xxx.yy represents the fw version of e.sybox, while kkk.zz represents the fw version of e.sylink

Procedure for updating the .bin file on e.sylink:

To change the e.sylink firmware or update e.sybox with a recent version you must have the .bin file with the most recent version of e.sylink and e.sybox issued by DAB (www.dabpumps.com), a PC with Windows 7, Vista or XP operative system and the USB cable with B type connector supplied with e.sylink. If you want to replace the file with a new version, follow the procedure described below: (the USB will power the e.sylink during the update)

1 - Connect the USD cable supplied
2 - Switch on the e.sylink, holding down any key.
3 - The e.sylink disk unit will appear on the PC 3
4 - Delete the file present
5 - Copy the new .bin file

It is now possible to update e.sybox with e.sylink, using the wireless interface 802.15.4. To do this the two devices do not need to be associated with each other. Updating takes about 1 minute.

Procedure for updating e.sybox with e.sylink:

On the e.sylink control unit	1	Switch off the e.sybox pump you want to update.
	2	Position the e.sylink control unit in the immediate vicinity of the e.sybox pump
	3	Disconnect the e.sylink control unit from the power supply
	4	Holding down the 2 keys ≪ ≪ simultaneously, supply power to the e.sylink control unit.
	5	Release the keys and check that the green LED ≪ is lit.
	The e.sylink is now ready and will remain in standby for about one minute.
On the e.sybox pump	6 H	Holding down the keys [MODE] and [-], supply power to the e.sybox
	7 R	Release the keys.
		At this point the e.sybox display will show the message “LV LOADER v y.x” and an empty progress bar; after a few moments the bar will start to fill, showing that the updating phase has started which will take about one minute.At the end of this phase the e.sybox will reset automatically, starting the new program.Now it is necessary to check that the firmware is correctly installed.Once the pump has been restarted, the display shows the home page. Press the [MODE] key 6 times until page VE is shown.If the expected version is shown on page VE under the heading “SW V.”, the operation has been successfully completed.
	Repeat this procedure to update other e.sybox units.

If the update has not been successful, the red Fault led will light up on the e.sylink.

Table 1 describes the number of blinks of the e.sylink FAULT led in the case of errors and the actions to be taken.

5 blinks The firmware installed on the e.sybox is more recent than that in the e.sylink.	The system is working correctly. Check it a more recent Firmware version is available.
4 blinks e.sybox firmware not present or corrupted	Load the correct .bin file
