This page describes how to update the firmware on an IO12.

The IO12 can be updated using a Barionet and a PC/Mac using a terminal program to control the BCL application named MBT (Modbus Tester & Loader). The terminal program can connect to the application MBT either via network (TCP) or a serial (RS-232) connection (two different BCL applications).

Prerequisites

Prepare the following material:

PC or Mac with e and a terminal program such as hyperterm
Optionally: a serial port (HW or USB2serial) and a serial cross cable (3 wire, DB9 female to DB9 female)
A Barionet 50 (FW 2.00 or higher) or a Barionet 100 (FW 2.08 or higher)
Modbus Test & Load BCL application: choose MBT_Vxx_S.cob for serial cable or MBT_Vxx_T.cob for TCP terminal control (xx= stands for actual version number). Download the MBT file from the Barix download section
Power supply 9VDC (min.) to 30VDC (max.), to supply both Barionet and IO12, 300mA (min.)
4pin Extension cable to connect to Barionet 50 or 4 wires to connect to Barionet 100

⇒ Tips:

Using a Barionet 50 is simpler as it needs no wiring: The supplied 4 pin extension cable can be used !
Using the TCP version of the application is simpler as it needs no serial port and serial cable ! It works via the Ethernet network connection.

Hardware setup

Connect the PC/Mac and the Barionet to your network switch or hub.
Prepare the power supply to connect it to the Barionet in a later step.
Depending on the kind of application control connection do the following:
- If you plan to use the TCP version of the application skip to step 3.
- If you plan to use the serial version of the application: Connect the PC/Mac to the serial port of the Barionet with the cross cable
Depending on which Barionet you choose wire the IO12 as following:
- If you use the Barionet 50: bridge the Barionet 50 (J10) and the IO12 (J9 or J10) using the supplied 4 pin extension cable.
- If you use the Barionet 100: As the 4 pin extension cable is NOT supported, connect the Barionet 50 to the IO12 using 4 wires via the screw block terminals as following:

^{Barionet 100}	^{Signal / Wire}	^{Barix IO12}
^{J6 pin 15}	^{Power +}	^{J5 pin 1}
^{J6 pin 16}	^{Power -}	^{J5 pin 3}
^{J7 pin 4}	^{RS485 A}	^{J11 pin 1}
^{J7 pin 5}	^{RS485 B}	^{J11 pin 3}

Software setup

Power up the Barionet and gather the IP address (check your DHCP server, use the Barix Discovery tool or use the ARP trick as explained in the Quick Install Guide)
Depending on the kind of application control connection do the following:
If you plan to use the TCP version of the application:
- Load the file MBT_Vxx_T.cob (xx is the version, at the time of writing: 11) into the Barionet's page WEB4 (Barionet 50: via extended web update, Barionet 100: via tftp), reboot when done and wait 10 seconds
- Start a terminal program (Telnet session) and connect via TCP port 12345 to the IP of your Barionet
If you plan to use the serial version of the application:
- Load the file MBT_Vxx_S.cob (xx is the version, at the time of writing: 11) into the Barionet's page WEB4 (Barionet 50: via extended web update, Barionet 100: via tftp), reboot when done and wait 10 seconds
- Connect the PC/Mac to the serial port of the Barionet with the cross cable
- Start a terminal program with the serial settings 9600,8,N,1 no HW control

Firmware Update procedure

After the above Hardware and Software setup the terminal shows:
Modbus and X8/R6 Test Application

Please select: 1 for factory, 2 for service mode, 3 for loader
Hit the number 2 and hit the Enter (↵) key for sevice mode. The terminal shows:
Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?
To check if talking to the IO12 is possible enter R0,256,4 (capital R, zero, comma, two, five, six, comma, four) and hit the Enter (↵) key. The terminal shows:
R0,256,4

READ: 00B3 0008 000C 0052

The first group (word) of digits tells the HW Type (0x00B3=IO12), the 2nd tells the current version (version 8), the 3rd the Serial 1 (0x000C=12 decimal) and the 4th the Serial 2 (0x0052=82 decimal). Both serials can be found on the data plate of the IO12 !

⇒ If you do NOT receive a reply check the wiring. Another reason for this failure could be the settings of the device. See section IO12 Defaults Parameters Jumper on the Barix IO12 wiki page to assume defaults.
Now that we know that the connection works we can start with deleting the existing firmware by entering F12,82 (capital F, serial1, comma, serial2)
⇒ Make sure you use the correct serial numbers 1 and 2 (decimal values not hex) of YOUR device !!!

and hit the Enter (↵) key. The terminal shows:

F12,82

?

Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?
⇒ Do NOT be fooled by the question mark. The IO12 will carry out the Erase command and after 5 to 10 seconds the PWR LED will go dark.
If the PWR LED stays lit then repeat step 4 carefully.

If after repeating step 4 the PWR LED stays lit then contact Barix support to check if the device must be returned to Barix (via reseller) for factory programming.
Hit the X (capital X) and then hit the Enter (↵) key to exit the service mode. The terminal shows:
Modbus and X8/R6 Test Application

Please select: 1 for factory, 2 for service mode, 3 for loader
Do NOT wait and hit the number 3 and hit the Enter (↵) key for loader mode. The terminal shows:
wrong serial setup - correcting & rebooting ..
After the reboot the loader mode will be started automatically. The terminal shows:
Modbus and X8/R6 Test Application

Please select: 1 for factory, 2 for service mode, 3 for loader

loader started, please reset unit. Press F for erase command, S to send firmwar
Hit the S (capital S) and then hit the Enter (↵) key to start the firmware update. The terminal shows:
sending firmware

⇒ This will take about 20 seconds (the RS-485 LED of the Barionet flickers during transmission) and when done the terminal shows:

end programming
firmware load complete
If it says "end prgramming" only go start over to repeat the erase command (step 4) because it will only accept programming when erased prior to programming
⇒ After a seconds the PWR LED will be lit.
If it stays dark power cycle the IO12 (disconnect the power wires, wait 4 seconds and reconnect power wires)

If it still stays dark repeaet power cycling up to 3 more times

If it stays dark go back to step 4 and repeat the erase command
Hit the X (capital X) and then hit the Enter (↵) key to exit the loader mode. The terminal shows:
Please select: 1 for factory, 2 for service mode, 3 for loader
Do NOT wait and hit the number 2 and hit the Enter (↵) key for service mode. The terminal shows:
wrong serial setup - correcting & rebooting ..
After the reboot the terminal shows:
Modbus and X8/R6 Test Application

Please select: 1 for factory, 2 for service mode, 3 for loader
Hit the number 2 and hit the Enter (↵) key for sevice mode. The terminal shows:
Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?
To check if the update of the IO12 went fine enter R0,256,4 (capital R, zero, comma, two, five, six, comma, four) and hit the Enter (↵) key. The terminal shows:
R0,256,4

READ: 00B3 000B 000C 0052

The second group (word) of digits tells the current firmware version (now 0x000B stands for version 11).

⇒ If it still says the old version then the update failed. Start over from the beginning.

Gratulations, you succesfully updated the device.
