I've been running an HD44780 under CrystalControl and Winamp on the parallel port.
Wanting to free up this port I've purchased a Matrix Orbital LK162-12 thinking this runs purely of a USB port.
The unit powers up and displays it's "Matrix Orbital LK162-12" screen
however LCDC nor windows recognises the display (drivers are installed).
Do I need to set the links differently or do I need a serial connection as well
4 wire USB connection
Hi Alexa!
Thank you for posting on Matrix Orbital's Support Forums.
Unforunatley the LK162 does not come in USB support. All communication for the device will go through COM 1 or 2 via serial communication. You will not need to install drivers for this display to work as it will be through a serial connection. I hope this helps!
I look forward to hearing from you.
Take Care

Hi Alexa,
Unfortunately, we currently don't have a usb to serial converter available, but that is another solution for freeing up the com port. You can do a search on usb to serial cables, and you will see a lot of results for them.
The only other solution I can come up with is to get a usb device, but they are larger than the the LK162-12s.
I apologize for any inconvenience this may have caused you, but I hope I was able to help you as best as possible.

Thank you for your reply.
Usb to serial has solved my problem.
The second USB to serial I tried worked.
The PCMCIA to serial I had wouldn't work.
A Parrallel to serial cable wouldn't work.
I did notice another PCMCIA that provided 2 serial ports of the 1 cable.
Does this mean I could parallel up two serial ports of one cable plugged into a serial port??????
Only having general knowledge I find computer setups work one way one day and not the next.
Without pure trial and error nothing seems certain.
Ahhh life!!
Does your product mean a key press writes information directly to the screen?
I need to do this and will repost if I can't find sufficient information.
I find your product outstanding.
Thanks

Hi ALEXA,
Glad you got your unit working. If you have a cable that has two serial outputs, then that cable probably controls two serial devices at the same time, but not independantly. If you are using a PCI card with two seriall om ports, it probably creates virtual comports. You would need to look up the manual of your device to check how it works. You can control the devices independantly, if you have virtual com ports.
When you press a key, you can have information displayed directly to the screen, but it needs to be programmed. When a key is pressed, a character is generated, and it is sent down the receive line of the host system. You will then program that character accordingly. What software are you using to control the device?

You can program your keys to display different screens or do different functions in LCDC. I have included an example of what you can do in the picture below. The picture indicates the programming of having the display skip to the next screen when you press a character.
To determine the character you get from the keypress, you can press a key, and the character will show up on the test log in the Test/Configuration section shown in the picture below.

Brilliant.
Will give it a go.
Your Aussie distributor "Dominion Electronics" provided a No. 1 sales rresponse.
Is there anyway to run the LK162-12 and a separate USB device over a single 4 core cable?
I use the USB 5 volt for power, leaving 2 cores for data or do I need 4 cores to separate the data from each?

What you can do is check whether the USB to serial cable can provide power to the device. If the cable does provide power, then you can have power and communications going through the DB-9 connector. All you would need to do to have power via the DB-9 is do the modification shown in section 2.1.2 in page 12 of the manual at http://www.matrixorbital.ca/manuals/LK_ ... 12_220.pdf
If not then you can use the usb cable for power, and have the data lines control something else. I don't see a problem if you have seperate power for your other device.
If you have anymore questions or concerns, please feel free to post them.

Yes.
Both the USB device and the LK162-12 share the USB cable power wires
The USB cable's 2 data wires are for another USB Device.
Another two separate wires are needed for the data for the LK162-12 which requires a 6 core cable altogether.
(2 power 2 serial data and 2 USB data)
I would really like to use the 4 core curly cord I have to run both devices.
The cord and cores are unshielded.
Can I possibly run serial and USB data over the same 2 wires?
Also:
Because I'm replacing a current HD44780 non backlit display with your LK162-12 The depth is a problem.
Does your LK162-12 come in a non backlit format?
If not can your daughterboard be used to drive the LK162-12 display via a ribbon cable?
Or can your daughterboard be used to drive the shallower HD44780 display via a ribbon cable?
If so are your lcd display connections (with particular regard to the power terminals polarity);

2. + 5volt/Power/Vcc
3. Contrast?Vlc

Hi ALEXA,
You cannot use the same wires to communicate both serial RS-232 communications and USB. The reason why you won't be able to do this is because both units communicate at 2 different voltage levels. The serial communications utilizes voltage levels of +-12V, and USB is 0 to 5V. If you send +-12V data to the USB device, you can risk damaging it.
If you wish to disable the backlight you can have the brightness set and saved using the application called uproject. You will just need to set the brightness to to the lowest value, which is 0, and save that setting. Uproject can be downloaded at http://www.matrixorbital.ca/software/so ... /uproject/
The serial interface board of the LK162-12 or the daughter board, as you refered it, can drive the HD44780, but the contrast settings may be a little different if you use your own parallel display. You can seperate the two LK162-12 boards and lengthen them with your ribbon cable. The pinouts are the same as shown below. You must know that any damage from seperating the two boards results in voiding the warranty though.

You can also use the x-boardto interface to your parallel display, which can be found at http://www.matrixorbital.com/product_in ... ace-module
The I2C bus does have limitations to cable length. An I2C bus can be a maximum length of 10 meters.
