Using a PS/2 keyboard on a Sparc workstation through the serial port

We have recently migrated an application that used to run on a PC, to now run on a Sparc Workstation. This is a SunBlade 1500, running Solaris 8. The application is running in a dedicated console which has a fitted keyboard and trackerball that have PS/2 connectors and cannot be changed.
We need a way of connecting the PS/2 keyboards to the serial ports of the Sparc workstation. We already have a piece of software that will read ascii values from the serial port so we definately want to go through the serial ports.
Can someone please suggest what converters will be required to get the output of the keyboard and trackerball as ascii input to the serial port.

Actually, that's not a bit perverse, at all.
Jonathan's suggestion is a standard method of connecting to a server.
(null cable between the computer serial ports)
... see the Solaris man pages.
man tip
TeraTerm and Hyperterminal are customarily used on a PC running some dialect of Windows.
The 'tip' command is all that's necessary between Solaris systems.
PS/2 is not a serial connection, but is a keyboard/mouse interface 'invented' by IBM when they offered their XT-class PS/2 line of desktop systems, back in the 1980's.
I found this next link by using Google:
http://members.chello.at/theodor.lauppert/computer/ps2/
The smaller DIN ports were more compact than the AT-class keyboard ports and the mouse moved from a serial port to a dedicated mouse port.
Serial communication devices are not keyboards, per se,
and keyboards are not serial communication devices.
You need other hardware in between to translate what the human being sends, and another computer is a common method to accomplish that translation.
Having said all that ...
Since you cannot change the dedicated console hardware,
I suggest you go to the manufacturer of that console equipment
and have them suggest some sort of serial-to-serial interface lash-up.

I want to transfer data through the serial port in the same coding that hyperterminal uses. How can i do it?

The serial port seems to be working, and labview seems to be sending the data, but the problem is in which format does it send the data, because in hyperterminal i just input the string "JDX" and it sends it to my device, with labview it sends something but my device does not recognize it.

Hyperterminal adds the carriage return/line feed to the string which is
generated by the return key to send out the current line. LabVIEW simply
sends out what you tell it, so try to set the string to "Show \ Display"
format and add a \r or \n or \r\n to the command you want to send out.
Assumes of course that you set the right baudr
ate/bits/parity etc in
LabVIEW with the VISA property node, when opening the serial port.

I want to build an array using the data that I get through the serial port

I am reading data through the serial port, but I want to buffer these data. I have seen a function, but i think that i can use this if I am reading data from I/O intrument, so I don´t how can I fill an array, with the data that I am reading!!!
Thank you!!!

I'll hazard a guess that you are reading data with VISA as a string. Then you want to convert that (probably with Scan From String) into a number. Then, you want to collect those numbers into an array.
We don't really have enough information to tell you the best way to do this. Here are some ideas.
If you are reading all the numbers from the instrument at once (e.g., a waveform from a scope), you might consider using "Spreadsheet string to array". Most scopes return the data as ASCII with commas between the values, so you'd wire a "," to the "delimiter" input of the "Spreadsheet string to array" function.
If, however, the instrument is returning a single point at a time, there are more questions. Do you want to do this continuously, or do you want t
o collect only a certain number of data points, and then process them as a block?
If the latter, then you'd just acquire each data point, convert it to a number, and then use output indexing on the for loop to create your array.
If the former, then you may want to store the data in a queue, and read it from the queue elsewhere in your program.
If you let us know what you want to do, we can probably provide more precise help.

How can an image be displayed by using raw data read from the serial port?

Hi there,
I am using an embedded camera to take photos. To operate it i send commands to it via the serial interface. I have received all of the image data back through the serial port and can view it as hex data in a string. The image data is 16bit colour RAW data at 160x120 resolution meaning i have 38400 bytes of data (160x120 = 19200. 19200*16 = 307200. 307200/8 = 38400). I want to be able to display this data as a picture, but cannot figure out how to do it. Can someone please point me in the right direction? i have been fiddling about with lots of the pixmap functions but no luck. Do i need to put this data in to a 2D array first?

Yes, first convert it into a 2D array of pixel values. From there you can convert it into an image to display it in a picture control.

By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

rajlego,
in the Keyboard pane of System Preferences, select the Shortcuts tab, and then select Mission Control on the left-hand side. On the right-hand side, make sure that the Mission Control checkbox is checked, double-click on its current key combination (by default “^↑”) so that the key combination is highlighted, and then press the F3 button — that will set its shortcut to be F3. You can now press F3 to bring up Mission Control without needing to also press the Fn button.

How can I use the output value from SIMPLE PID to write something to the serial port?

I am working on my Senior Design Project that requires the use of incoming compressed air, propotional valves, continuous servo motors, and a serial servo motor microcontroller. I have figured out how to send byte sequences to the microcontroller through LabVIEW using the VISA serial write function. The motors are attached to the valves to control the flow rate. I have created my own simple feedback system using a bunch of case structures but I realized that I am basically trying to recreate the wheel (I basically was writing my own PID VI). I have an older version of LabVIEW (7.0 Express) and theres no way to upgrade or buy the PID toolkit, so I am stuck using the Simple PID VI. Also, the only way the motor works is sending an array of bytes to tell it to turn on/off, direction, and speed. Is there any way I can use the Simple PID VI in conjunction with the VISA SERIAL write function, or is there any other way I can communicate with the serial port using this pid vi? Any information would be appreciated.

Hi gpatel,
you know how to communicate to serial port, but you don't know how to send a value from SimplePID to serial port???
You know how to communicate, but then you don't know how to communicate???
You should explain this in more detail...
Edit:
From you first post you know what values your motor driver is expecting. You know which values the PID.vi is providing. Now all you need is a formula to reshape the values from PID to the motor. It's up to you to make such a formula. Unless you provide any details we cannot give more precise answers...

How to use the serial port

hello
I would like to know if there is other library than comm to use to establish communication with the serial port ..
can we do this with pure java ,I mean without the need of using any library ???
if not then what is the best library to use ???
any examples ??
I have other question
when i use the library comm
I use the public void serialEvent(SerialPortEvent event) to get my data
but that data comme line by line
is there a way to get all the data at once ???
than kyou in advance

There you go

How can I use LabVIEW to send the equivalent of a CTRL D (in VT 100 format) out the serial port of my computer?

I am trying to write a vi that interfaces with a piece of OEM equipment that is set up to talk with a VT 100 terminal. I can't seem to locate the ASCII equivalent string (if there is such a thing) of a CTRL D. Is there a vi that emulates VT 100 commands?

If I recall, CTRL-D is EOF on most ASCII tables.
You'd probably have to use an escape sequence
or if you can use an unsigned 8-bit that might be
easier.

It will use minimal internet bandwidth unless your content is streaming from web>iPad>AppleTV.
Local network comms for content already on the iPad (eg presentations) will not generally use internet bandwidth apart from protected iTunes material that requires brief internet authorisation.

MEASURING FORCE ON BALANCE USING AN ELECTRONIC BALANCE FROM THE SERIAL PORT

Hi,
I am trying to measure FORCE using an electronic BALANCE from the serial port. My measurements are strange! The BALANCE sometimes give ZERO reading! Is it because of the sample rate, baud rate etc? I have attached the readings concerned.
Attachments:
databalance.doc ‏144 KB

I think your problem is due to the way you read the weight :
1/ask the balance to send the data
2/oversee the byte number on the serial port until it is constant
3/read the bytes received
4/convert to number
During step 2, you compare the bytes at serial port with the previous value. So far, you have been very lucky to be able to read something : the answer here is always ZERO since the readings occur BEFORE the balance has been able to send anything! means that your loop stops immediately (if you are not convinced, jujst add an indicator to display the loop index. However, since you added a wait (0.8 s), when going to step 3, the balance has had some time to send something. Here, you should not have read again the number of bytes at serial port, but that unwillingly corrects the previous error and you can read most of the received data...
You should modify completely your algorithm. Usually, a balance send the weight as a string with some terminator (RC or LF). Accordingly, the algorithm should be :
1/ask the balance to send the data
2/read the serial port, concatenating the received chars until a terminator char is received or a timeout has occured
3/convert to number

My macbook does not have a firewire port. Is there any kind of adapter that will allow me to use my advc 300 (which need to plug in to the FireWire port)?

My macbook does not have a firewire port. Is there any kind of adapter that will allow me to use my advc 300 (which need to plug in to the FireWire port)?

Firewire, USB and the recent thunderbolt use completely different protocols, therefore there are no adapters for mutually adapting them, just a computer, which allows connecting them, and will work as an interface. For example, if you have an external disk in an enclosure with only FW connection and another one with USB connection, just your mac, having both, allows their interconnectivity.
If your mac does not have FW (the brief alu MB series, Air) you cannot connect a FW device, if only FW port is there.

IMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store

iMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store. I can't pay for it so I would really appreciate the help.

Look in your applications folder for the installer - Install OS X Yosemite. Delete it. Then go back to the App Store purchases tab and see if you can download it. You might have to re-index Spotlight.

Sending an ESC code using the serial port

I have a motor control aplication that requires sending an ESC character using the serial port. LabView has several built-in functions (end of line, line return, etc.) but I just do not know how to send this particular code using the serial port. Any ideas?

The hex code for ESC character is 1b, Try writing it in a 8 bit unsigned number and then change that byte to charachter using labview function "byte Array to string". In this way you can pass this charachter.

When using an airport extreme to extend a wireless modern, will the lan ports work?

When using an airport extreme to extend a wireless modern, will the lAN ports work?

The AirPort Extreme can extend the wireless signal from another Apple wireless router. When it does, the Ethernet ports on the extending AirPort router are enabled.
Apple's "extend" feature appears to be a proprietary Apple function, so it would be extremely unlikely that an AirPort Extreme...or any other Apple router....could extend a 3rd party router product wirelessly....if that is really what you are asking here.

I can not communicate with the FP-1000, using the serial port.

FP-100 communication by serial port.
My problem is the communication with the interface FP-1000, I haven been using it for two month with my program application and suddenly it stopped to work. I tried to use the FieldPoint Explorer to communicate using its last configuration but it does not work. I have tried to configure again and the FieldPoint Explorer doe not find any module, also I have seen that the network and access LEDs don lit when I am trying to communicate with the FP-1000.
I have checked all connection and they are already, the FP-1000 turn on, and the status LEDs does not lit.
I guess the trouble is the RS-323 connector at the FP-1000.
Could you tell how can I solve this problem?

Hello,
There are a number of things that you can try when you are experiencing communication problems with a FP-1000.
First, double-check that the serial port that you are using is the same one that you are specifying in FieldPoint Explorer. Try using another serial port on the host computer. Try connecting the FP-1000 to another computer.
Make sure that you have FieldPoint Explorer version 3.0.2 or later. Free upgrades are available from the web.
I hope this helps,
Chad Evans
