FUNCTION MO ES:
The device has got two function modes depending on the position of the ‘Dip2 of Dip-Switch A’:
The first, with ‘Dip2 of Dip-Switch A’ at “OFF” position, is used for the normal working of the device
The second, with ‘Dip2 of Dip-Switch A’ at “ON” position, is used for uploading the Project and/or Firmware
For the operations to follow for the updating, see ‘UPDATE DEVICE’ section
According to the functioning mode, the LEDs will have specific functions, see ‘LEDS’ section
Warning:
Dip1 of ‘Dip-Switch A’ must be at ON position to work even if the Ethernet cable is not inserted

LE S:
The device has got six LEDs that are used to give information about the functioning status
The various meanings of the LEDs are described in the table below
LE Normal Mode Boot Mode
1: HART communication
(green) It blinks when HART communication is running Blinks quickly: Boot state
Blinks very slowly (~0.5Hz): update in progress
2: Ethernet link (green) ON: Ethernet cable connected
OFF: Ethernet cable disconnected
ON: Ethernet cable connected
OFF: Ethernet cable disconnected
3: Modbus communication
(green) It blinks when a Modbus request is received Blinks quickly: Boot state
Blinks very slowly (~0.5Hz): update in progress
4: Device State
(green) Blinks slowly (~1Hz) Blinks quickly: Boot state Blinks very slowly (~0.5Hz): update in progress

HART:
“HART” is an acronym for Highway Addressable Remote Transducer The HART Protocol makes uses Frequency Shift Keying (FSK) standard
to superimpose digital communication signals at a low level on top of the 4-20mA This enables two-way field communication to take place
and makes it possible for additional information beyond just the normal process variable to be communicated to/from a smart field
instrument
It is possible to provide the current loop for HART communication and an additional low power supply @ 24 V DC for feeding HART devices
by setting Dip-Switch D at ON position
Current loop for HART is required when there is not an external device in the bus that provides it

RS485:
For terminate the RS485 line with a 120Ω resistor it is necessary to put ON dip 1, like in figure
The maximum length of the cable should be 1200m (4000 feet)
Here some codes of cables:
Belden: p/n 8132 - 2x 28AWG stranded twisted pairs conductor + foil shield + braid shield;
Belden p/n 82842 - 2x 24AWG stranded twisted pairs conductor + foil shield + braid shield;
Tasker: p/n C521 - 1x 24AWG twisted pair conductor + foil shield + braid shield;

ETHERNET:
The updating of the converters must be made using Connector4 of the HD67908-X-A1 with at least a Category 5E cable The maximum
length of the cable should not exceed 100m The cable has to conform to the T568 norms relative to connections in cat 5 up to 100 Mbps To
connect the device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC/PLC/other is recommended
the use of a cross cable

USE OF COMPOSITOR SW67908:
To configure the Converter, use the available software that runs with Windows called SW67908 It is downloadable on the site
www adfweb com and its operation is described in this document (This manual is referenced to the last version of the software present on
our web site) The software works with MSWindows (XP, Vista, Seven, 8, 10; 32/64bit)
When launching the SW67908, the window below appears (Fig 2)
Note:
It is necessary to have installed Net Framework 4

NEW CONFIGURATION / OPEN CONFIGURATION:
The “New Configuration” button creates the folder which contains the entire device’s configuration
A device’s configuration can also be imported or exported:
To clone the configurations of a programmable “Modbus Slave / HART Master” in order
to configure another device in the same manner, it is necessary to maintain the folder
and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the
button “Open Configuration”
