Software upgrade policy:

Software upgrades are free of charge. For timers, I'll have to do the upgrade. For the Control Box, you can decide to do it yourself.

For the units I'll upgrade, you have to pay the postage for an insured package for the return. For most contries it is something like 150-200DKR.

How to upgrade the Control Box:

Step 1 - Build the programming adaptor.

Build a programming adapter cable. At one end, there should be a 3 pin SIL female connector, pin spacing = 2.54mm = 0.1", at the other there should be a SUB-D 9 pole connector.

Connect as follows:

SIL pin 1 to SUB-D pin 5, Black wire

SIL pin 2 to SUB-D pin 3, Red wire

SIL pin 3 to SUB-D pin 2, Blue wire

Step 2 - Download software.

Download the latest software version CBox1_06.txt, right-click here to download.

Or the previous version CBox1_05.txt, right-click here to download.

Step 3 - Prepare the Control Box for programming.

Remove the batteries from the Control Box.

Open the Control Box by removing the 4 screws at the bottom. Be careful when you open the box, make sure that you note all the positions of the connectors and wires. Leave all connectors, including display connector connected.

Step 4 - Connect the programming adaptor.

Identify the two RS232 connectors, 2 rows of 3 pins, located close to the keyboard connector. Connect the adaptor to the outer row in the following order from the end of the display connector edge: Blue - Red - Black, pin numbers 3 - 2 - 1.

Connect the adaptor accordingly.

Step 5 - Set up HyperTerminal. 

Set up HyperTerminal on your PC as follows (located under START - PROGRAMS - ACCESSORIES - COMMUNICATION - HYPERTERMINAL):

Connect to the COM port you intend to use

Settings:

Windows keys

Backspace = delete

Emulation: VT100

Port Settings - Configure:

Bits per second (Baud): 19200

Databits: 8

Parity: None

Stopbits: 1

Flow control: None

ASCII setup:

Send New Line after CR

Line delay = 20 milliseconds

Step 6 - The actual programming.

The Control box checks for a connected PC as first thing when powering up.

Hold down the SPACE key of your PC until the control box is up and running.

Connect the DC adaptor to the Control Box, still keep the SPACE key depressed.

The Control Box should respond by sending the menu text. If so, release the SPACE button and you are in loader mode.

Choose E for Erase FLASH

Choose S to load S-Record file

In the HyperTerminal Menu, choose Transfer - Send text file

Choose CBox1_xx.txt that you just downloaded

When the menu is back, the Control Box is updated.

Remove the DC (power) adaptor

Remove the programming adaptor

Assemble the box again.
