Issues connecting to serial port A from Linux to Sun Ultra 2 workstation

All,
I've been working on this for a couple weeks now. I started off with a couple of modular connectors and tried making my own adapters. I followed the wiring diagrams, and even tried numerous ALTERNATE wiring diagrams for a null modem cable. The most i could get was to be able to watch the Ultra 2 boot from Minicom in linux. I can't send anything, not even break. Finally, frustrated, i ordered a real null modem cable - DB25M to DB9F. I made sure the jumpers were set on the mainboard for RS232. You can imagine my frustration, then, when i discovered this morning that i STILL could not send keystrokes over the serial cable.
I am at the end of my rope. I cannot imagine what else i need to do. Minicom is set to use ttyS0 @ 96008N1.
Any tips, guys? I'm ready to give this machine away to someone with an Annex or or wyse terminal since i'm failling so hard.

I have a solution - in the CMC, set the repo to use DNS. You need to first create an appropriate entry in the <install dir>/sap_bobj/enterprise_xi40/odbc.ini and then create an equivalent entry on your client ODBC settings.

Connection to serial port via USB adapter- error -2147221503

I am trying to drive a stepper motor provided with possible Labview or VB programs. This motor is supposed to be connected via serial port, but the computer has not some, so I bought an USB adpater to connect my motor via USB. I am using the labview programs provided (Labview 8.0). The program cannot connect to the port and returns error -2147221503. Where may I find some help with that ?
Thanks

I see references to 'Luminos'. Is this the provider of the stepper motor and LabVIEW code? If so, your first step should be to contact them. The whole VI is nothing but ActiveX properties and methods and the vendor would be the only one who knows what is going on.

Listing folder from a main board connected by serial port

Hi
I have a main board, I connected it serially and accessed it by VISA application and I have managed to write to and read from it.
My problem is how to list the folder from the board. There are many files in every folder with different file format.
Any help will be appreciated

It is advanced embedded board, it can be counted as a storage device. We are aiming for friendly LV user interface for the customer to view the file stored on it.
And farther we want to list the files, and might add:
loadapp                       (load application loader file)
loadmax2                    (load and program the Max2 using jam stapl)
reboot                         (reboot the blackfin)
boot <filename>        (boot an application)
flashapp                     (program the loaded application loader file to flash)
setboot <filename> (tell bootmanager which application to boot on startup).
unsetboot                  (reset the application to boot).
setmac <address> (ex. setmac 01:f0:cd:45:1f:2a).
setip <address>        (ex. setip 192.168.0.150).
dir                             (list all files).
settime                      (ex. settime 12:04:01).
gettime                      (print out time).

Communicate via serial port/ethernet from client app

Hi
Is it possible to communicate between the client serial port and an Apex application?
(or from the application to an ethernet device).
I need to link an application to a weighing machine and send/receive information via an Apex application. The interface will either be a serial port on the client or the weighing scales could also be connected as a network device.
Any ideas?
Thanks
Kathryn

There are active-x controls that you can use (http://www.activexperts.com/activcomport/howto/html/).. Otherwise you could try writing a small java applet to do this on the client end, don't know enough about your requirements to offer more.. Does the vendor of hardware have a solution?
(Issue with this would be, non-ie browsers MIGHT not want to run vbscript or active-x controls..)
Thank you,

Process Name when we connect via Serial Port ,Its URGENT !!!

Hi,
I am working with Sun Solaris 9 sparc and in my application,I have to communicate with the serial port.
For every connection we made, in Solaris it creates a process.So Can anyone tell me the name of the process when we connect serial cable??
like USB connection /dev/usb0 or /dev/hiddev0 process is created..
Thanks in Adavnce ...

For every connection we made, in Solaris it creates a process.Are you talking about 'telnet' or 'ssh'? Those work differently from serial connections.
So Can anyone tell me the name of the process when we connect serial cable??You might have a login listener if you configure it, otherwise, nothing is running.
You need to provide more details about how you intend to use the serial cable. I can't tell from your post.

Writing to serial port 1 from a PDA

ok this program is driving me NUTS! i have this microchip which uses a certain protocol... now this protocol requires that you send it some characters in hexadecimal so it'll reset... afterwhich it'll send you a data packet containing the version of the microchip etc etc (it's an aduc812... which you can find on www.analog.com)... anyway, that's not important... i am having trouble actually WRITING to serial port 1... i noticed that doing it through an actual PC requires some sort of "open serial port.vi" which is not available in the pda version... all i have is init.vi which is apparently not enough from what i am told... i thas to be opened first... initialized next... then written to then read from... does anyone know how i can acc
omplish this open procedure with the pda module? is that some sort of software i'm missing? why isn't it included with the pda module add on... etc etc... thank you in advance... i really need help with this so as much information as possible would be appreciated... let me know if you need further info...

Connection to serial port for communication RFID

HI,
I have occurred problem in communication to serial port for accessing the RFID
through Serial Port COM1 or COM2 . I got garbage values of Card .
Please give me the code for accessing serial port and indicter the cadr is detected by RFID and read the data on card.

EHAG microchip 13,56 MHz dual reader and Mifare 1KB contactless smartcard.
I've succeed to retrieve the data from the transponder (card) but it just only once when i click the button from my application. My question is how do i retrieve the data continuously from the card for every few milliseconds?
sorry for my language.

Multiple serial ports reading from a shared USB port

I have a program that reads from 4 flow controllers, which send data through RS232 serial ports. Because the computer is located pretty far away, the vendor suggested to use an Edgeport box to convert RS232 to USB, then convert to ethernet port using a SuperBooster converter. The signal travels long distance in ethernet cable to the computer and get converted back to USB, then to the computer. In MAX, I was able to see 8 com ports from the Edgeport box, and I was able to communicate with my flow controllers.
The problem is, it will give me some error message occasionally. Sometime it's a VISA Read error, sometime it's a VISA framing error. Could this be caused by the way the signal is transmitted?
In the program I have four parallel WHILE loops that constantly do READ and WRITE to the 4 flow controllers. Could this be causing the errors? If so, what is the best strategy to design this program?
Thanks

I agree with Mike, you will need an error handling strategy that accounts for these errors. And retries the communications. This can be a little tricky, but very doable. I believe some sort of statemachine approach will work best for this.
As for your heated probe. I would make some sort of hardware interlock that will shut it down in case of a coolant failure. NEVER, EVER trust the computer to be running where safety is concerned, either for personal or hardware. There are plenty of ICs that can monitor temperature, and have warning, and alarm outputs! Another option is some sort of watchdog on the communications bus for the coolant control, but I think this is a bit more tricky.

Unwanted data strings in settings, for connectivity to serial port.

When my program connects to the unit, threw the serial port its recording an unwanted string value in my setting files. Causing "19,Read Key (Boolean).vie" Error to be recorded. Unable to locate where and why this is happening in my VI. Im very new to labview and still learning the basic. I have came up with the conclusion that this error started to happen ever since the last LABVIEW update. (Version 13.0f2).
Thank you,

This is my original copy of my labview code, i thought maybe updating it was causing the error 19.
The first Settings.ini is before my code is ran, second is the error after the code is ran.
I inherited a program and im trying to follow all the code to key in where the code is causing the error. Im not sure what exactly code I should post.

How to abort serial port VISA from wating.

Hello All
How can I abort serial port VISA while wating for a byte to arrive.
Lets say I have timeout set for 3 min. but I want to cancel it before that , how to do it programatically?
I tried to set timeout to 0 while wating for data, and it works, but I do not like this method.
Thanks in advance
Pawel

Hi again
I have made some investigations, and here is what I found:
None of Serial Port Brake nor Set Time out work while the "VISA read" is active. All property node can access VISA class only when the "VISA read" is finished.
Therefore, it looks like there is nothing I can do when VISA is active. The only solution is not to allow VISA read.vi to activate. I think I can use your idea and monitor the amount of bytes at the port.
I wanted to avoid it.
Thank you for your help

Issue connecting SPA3102 FXO port to paging interface

Hello,
I was referred to this community after a call to small business support, we were unable to come to a solution.
SPA3102 v5.2.13 FW
Viking Electronics PI-1 Paging Interface
We were told from Viking that the interface only supports an FXO port, all the connections were verified with their support and we're able to page by connecting an analog phone straight to the interface. Plugging into the FXS port on the SPA3102 also results in a dial tone playing over the paging system.
All settings on the SPA3102 are default minus SIP registration information, we see the unit as registered within the web interface as well as within our Asterisk CLI.
Trying to ring the extension results in constant ringing if voicemail is disabled, and straight to voicemail if enabled. Within the Asterisk CLI we see a SIP response 503 "Service Unavailable."
I can get the SPA3102 to respond by lowering the "Line In Use Voltage" down from its default value of 30. However all I hear is a hum and I'm not able to speak over the paging system.
Any insight into this issue would be greatly appreciated, we believe it's just settings on the SPA3102 unit itself that need to be changed.
Thanks!

Looking at the Viking Pl-1 web page installation instructions, I think the key setting on the SPA3102 would be to set the voip-to-pstn gateway dial plan to NONE. The "hum" you get when you lower the Line-In-Use setting sounds like the dial tone you would get with the default dial plan setting.
I would try the following:
Viking Pl-1:
Talk Battery Switch (PT): On
Audio In: Cabled to FXO port of SPA3102
SPA3102:
Interface Analog Phone attached to SPA3102:
Line 1 Tab
Line Enable: YES
Dial Plan: (S0<:@gw0>)
PSTN Line Tab
Line Enable: Yes
VoIP-to-PSTN Gateway Enable: Yes
One Stage Dialing: Yes
Line 1 VoIP Caller DP: NONE
VoIP Answer Delay: 0
Line In Use Voltage: xx
The Line In Use Voltage needs to be lower than the Talk Battery voltage supplied by the Viking Pl-1. Usually it is set about half way between the on-hook and off-hook voltage level. Measure the FXO (PSTN Line) on-hook voltage by reading it on the SPA3102 INFO Tab. Set the Line In Use Voltage substantially below the on-hook talk voltage.
If you lift the phone with the above settings you should be connected to the paging system.
Interface to an asterisk pbx system:
PSTN Line Tab
Setup Registration on PSTN Line Tab to Asterisk system.
Register: Yes
Proxy: xxx
UserID: xxx
Password: xxx
VoIP-to-PSTN Gateway Enable: Yes
VoIP Caller Auth Method: None
One Stage Dialing: Yes
VoIP Caller Default DP: NONE
VoIP Answer Delay: 0
Line In Use Voltage: same comments as above
If you call the extension on the asterisk PBX you should be attached to the Viking unit.

Eurotherm 2704 connection via serial port with ModBus

Hello guys,
first some words about my problem:
I have to develop a software which allows reading and writing the
temperature (we have 3 Eurotherm 2704) (I think some of you know this problem yet ).
I wrote already the program and it works, but I used "iTools OPC
Server" for my program and it was the demo version (works only 30 minutes).
The group doesn't want to pay for the iTools, I should solve this problem without
iTools .
In this forum I found out, that I can use the ModBus for it:
http://forums.ni.com/ni/board/message?board.id=170&thread.id=468139&view=by_date_ascending&page=2
I know, there are some similar threads here, but I am new with LabView
and need some help.
I downloaded one example “my modbus serial query.vi “
http://forums.ni.com/ni/board/message?board.id=170&thread.id=135288&view=by_date_ascending&page=2
but it does not work (I am not really sure, what I have to change in the
file)
With OPC Server I found out:
COM5
Baud Rate 9600
Parity: None
Flow Control: None
Data Bits: 8(RTU) (I can choose RTU, but where can I change to 8 bit ?! )
And by other properties, I have no idea what I have to change there
For Example
Modbus Data Unit In (all read and write mode ? Which one do I need to read the temperature and to set the set temperature?)
Modbus Command ?!!!
No idea.
I have folowing adresses (comms address 0x00030001, canonical address: 1)
Which one do I need ?!
I think if I get the signal from one temperature controller, I can do it for
other, but my problem is now THIS one.
Can you help me whit it ?
Should I use a other example ?! Maybe do you know better one?
Thank you, very much.
Alexander

Hello Putnam and Christian,
I think the problem because you can not understand my question is my English, sorry
I'll try it again:
@Christian:
Thank you for the links, but I think all threads in NI Forum with topic "Help, Eurotherm 2704 ?" were written by me
You understood my problem correctly.
We have 3 temperature controllers and I have to develop a LabView program, which allows reading the temperature from the controllers. It should be possible to write the set temperature from LabView to temperature controller as well.
The controllers are connected already (I think with RS485) and I can read/set the data from/to controllers (with “iTools OPC Server”), but I have to change my program so, that it works without “OPC Server”
@Putnam:
In the meantime I found out, why I got an error with “my modbus serial query.vi” (the solution was very simple, I had to close the OPC-Server ).
It runs now and I try to understand now how the VI exactly works.
Maybe you can help me with it?
I try to explain what I understood, if something is wrong, tell my please:
The “my modbus serial query.vi” allows to read the multiple values (maximum 125 register) (default block read size is 125) from controller (I can see the data in the register array). In each register I have values for different variables. The Modbus address of Loop1 PV (I need this value) is known ( 00001, Eurotherm manual).
Does it mean that the first element in the register-array is the value for the temperature from Loop 1 ?! (multiplicated by a factor, if it is correct, how can I find out this factor? It is linear?)
And if I need the value of Loop2 (the address is 01025), I have to set the start address for example to 1000 and in this case the 25-th element in register-array is the value for PV Loop 2 ?!
I got this idea, after I left the laboratory and could not try it out. I can do it first at Monday, but I would know if it is correct what I think.
If it is correct, I think I will able to change “my modbus serial query.vi” on my own, that it works in my program.
Or there is a better example/solution than “my modbus serial query.vi” ?!
The other problem would be writing of temperature, but I will ask about it later . First temperature READING problem!!
Thank you!
Alexander.

ConnectionNotFoundException when connecting via serial port

Hi all
I have got a HttpConnection that looks like this
HttpConnection connection = (HttpConnection)Connector.open( "http://localhost:80/test/read.txt" );
InputStream inputstream = connection.openInputStream();
...The above codes work fine on the emulator, but when I wish to connect to the server via the device from the usb cable, it throws me an javax.microedition.io.ConnectionNotFoundException
I'm working on a SE W880i and is running the midlet from the Device Explorer...

Hi,
thanks for the response.
no, I can't login to the switch(es) at all. There seems to be no response from hyperterminal at all. (Then I noticed that the LEDs had gone "solid" and that everyone started to complain they had lost network connection!)
Even when I powered off and powered on the switch with the console port still connected, nothing appeared on the hyperterminal screen.
However, as mentioned, I'm able to connect to one of our spare switches using the same settings, same laptop, and same console cable - so I guess that would rule these things out as being the cause?
Its definitely a strange one, especially as it seems to be affecting all 3 of the live switches!
