Can the Com port on the EX90 be connecting to an AMX NI700 to receive command?

if so, what are the pinouts for the EX90? (TX/RX/GND) The AMX uses pin 3 for TX, Pin 2 for RX and Pin 5 for GND. I have been using an RJ45 cable and trying to match pins but I am still not getting a TX signal. Also, does the COM port need to be enabled?

The EX90 is not really build to be controlled by an additional control system.
(in general thats a thing for the integrator prodcucts).
The Serial port is not a RS232 (+/-25 Volt), instead of their using TTL level.
So a direct connection without a proper cable might cause a hardware fault!
I think the serial port was on by default, but that might have changed on the current software versions, thats what works fine for me:
xconf // serial
*c xConfiguration SerialPort BaudRate: 38400
*c xConfiguration SerialPort LoginRequired: Off
*c xConfiguration SerialPort Mode: On
The serial port is also on the bottom of the device, its ok to use it if you need to
troubleshoot boot issues, but besides that not really usable.
Dont expect Cisco to do any support for this if you run in to strange behavior when
controling the system with a 3rd party control.
Btw, what I would strongly recommenced is to use the telnet/ssh cli or http(s) API.
could picture that this might work with the AMX700, so why even think of using a serial port, ...

Output Signal From a Desktop Flash application to the COM port

How do I script to connect /send a signal to the COM port of
the PC from a Desktop Flash application.
The Signals can be variables such as "1/2/3/4" . The signals
will be send on a corresponding click in the flash application. For
eg: if I click button "A" in the Flash application, it sends a
signal "1" to the COM Port. If I click the Button"B", it send the
signal"2" to the COM Port.
Please advise if it can be done directly or through a Third
Party software.

Go to Solution.

Windows 7 is not officially supported by National Instruments as it hasn't even been released. That means you won't get any official support from NI on this.
That said, does your computer actually recognize a serial port? Do you have an actual serial port, or do you have some sort of virtual COM port, or are you using some sort of adapter, such as a USB to serial port box? If it's any of the latter, the most likely reason is a driver issue which needs to be written to be compatible with Windows 7.

Write among COM ports in the same PC without cables

How can I write to the memory address(es) of a serial COM port? I would like to send data from one serial COM port to another in a manner similar to the that of the 'Simple Data Client' and 'Simple Data Server' vi examples. This must sound strange since this is exactly what a null modem cable will do, externally. I would like to eliminate the cable connection between COM ports that exsit in the same PC and communicate between them, internal to the PC, somehow.
Currently, I am using a LabVIEW vi to read a serial message on COM1, translate it, send the trsanslation out on COM2, so that a separate windows program (no .DLLs to interface with LabVIEW) can read the message on COM 3. COM 2 and COM 3 are connected by a null-modem cable. This requires three COM ports, and two serial cables. I realize that I can use a physical loop-back jumper on COM2, for instance, where I send and read the translated message on COM2, but I still wonder if there is a method for doing this in memory, or something. Is there a way to accomplish the same objective with one cable (into COM1), no loop-back jumpers, and only two serial ports? In summary, I want to read on COM 1, translate in LabVIEW, then write directly to another COM port, internally, without using a serial cable. Can the 'IN PORT' or 'OUT PORT' vi's apply here? Are these tools only for parallel ports?
Hope this is not too confusing.... It seems like I am always trying to do something with LabVIEW that was not meant to be done....
Thanks.

Thank you. If I pay the price they ask, this looks like it will create and share virtual COM ports - exactly what I need. However, I would really like to find a way to do this in LabVIEW, such that I do not have to make my application dependent on another piece of third party software. The 'Simple Data Client.vi' and 'Simple Data Server.vi', included in the shipset examples, seem to do this for TCP/ IP ports. I wonder why the COM ports cannot be addressed at the memory level, in a similar manner???

Re: if weblogic can serve two ports at the same time?

That's not true. WebLogic supports a non-secure and secure listener port at the
same time. That was one of the selling points for my organization.

Why do they 'have to be on different ports'? We block requests by URI
- so just
block all requests to /youradminapp/* at the firewall. Or you can block
them at
your Web Server. Or restrict them by user in WL.

I dropped my iphone 5 in the water, its dead and when I try to charge it the apple logo comes and goes, thats my only sign of life, I've done many after market repairs but what I want to know is if I should replace the ligntning port or the battery

I dropped my iphone 5 in the water, its dead and when I try to charge it the apple logo comes and goes, thats my only sign of life, I've done many after market repairs but what I want to know is if I should replace the ligntning port or the battery... or just buy a galaxy s5?

If you dropped it in water, and then plugged it in, you may very well have destroyed the battery and/or the logic board. Charging/plugging in to a power source is very damaging to wet electronic devices. There is not much you can do but replace the entire iPhone...and since you did repairs yourself Apple will not do an out-of-warranty replacement.
You can try replacing the battery, the lightning port is another issue, but I would not expect that iPhone to work again.

How to close the COM Port ??????????

Dear all :
I have written an application that send AT commands to a modem , Once I opened a com port , i don't know how to close it . I got the null pointer exception when i create a new channel , because the inputStream and outputStream is owned by the previous channel . So , some one can teach me how to close the com port that opened before ?
my source code for open port :
public void Connect_Com(CommPortIdentifier portId) {
Integer i = new Integer((int) (Math.random()* 1000));
String channel = "channel" + i.toString();
System.out.println(channel);
try {
System.out.println("preparing to open port");
serialPort = (SerialPort) portId.open(channel, 2000);
} catch (PortInUseException e) {}
try {
inputStream = serialPort.getInputStream();
System.out.println("getting inputStream");
} catch (IOException e) {}
try {
serialPort.addEventListener(this);
} catch (TooManyListenersException e) {}
serialPort.notifyOnDataAvailable(true);
try {
serialPort.setSerialPortParams(9600,
SerialPort.DATABITS_8,
SerialPort.STOPBITS_1,
SerialPort.PARITY_NONE);
} catch (UnsupportedCommOperationException e) {}

serialPort.close() ?
From the documentation of SerialPort:
- SerialPort extends CommPort.
- CommPort.close() closes the communications port.

Communicating via the Com port (comm)

Hi Folks,
I'm trying to communicate to the com port on my device but apparently can't "see" any available com ports.
Actually I'm trying to communicate via the Infrared port on my device and have been able to do so on a Nokia using COM0, however, on an Orange SPV, no ports are available. I'm using the Connector class from GCF.
I've used
System.getProperty("microedition.commports")
and on the Nokia get a load of ports back, however, on the other device I get back null. The device does have a IrDA port so I feel like I should be able to access it, I just don't know how.
I wondered if there is other ways to get hold of a port?
Reading http://developers.sun.com/mobility/midp/questions/properties/index.html it implies that the above property is implementation specific, does that mean Midlet Manager implementation specific (the SPV device uses Intent Java).
Thanks for any suggestions or any tips / links on IrDA / serial communication with ME :)
Cheers,
Toby

Start with the NI modbus library.
http://sine.ni.com/nips/cds/view/p/lang/en/nid/201711
Or download portmon and use it to watch the data as modscan is working. Then use VISA and serial port commands to transfer data bytes until it matches what modscan is transmitting. You'll learn more doing it this way.
Also download the modbus protocol pdf file.

Using VISA and RS232 devise , loosing the COM port .

Using VISA and R232 devise communicating fine with labview and I can Read and Write.
however, I want to turn OFF the devise, then turn it ON again (part of the test), and be able to continue .
The COM port is not communicating . unless I turn both the devise off and Exit LV then restart again.
How to do that without restarting LV.
thanks

" Is there a better way to make sure its closed and driver is not hanging onto the connection? "
you could try a command like " devcon disable usb\vid_0CD5*0003~" and then "devcon enable usb\vid_0CD5*0003~"
( you will need to figure out the ID of your device, my example is for a LabJack U3. )
Get the devcon.exe-utility from microsoft.
but as mentioned before, just watch what happens with device Manager (' run devmgmt.msc')...
to enable/disable a device in a VBS script you can use below example, (As Administrator!)
Option explicit
Dim oShell
set oShell= Wscript.CreateObject("WScript.Shell")
oShell.Run "RunAs /user:Domain\USER ""cmd"
WScript.Sleep 100
oShell.Sendkeys "USERPASSW"
WScript.Sleep 500
oShell.Sendkeys "devcon disable usb\vid_0CD5*0003~"
WScript.Sleep 1000
WScript.Sleep 100
oShell.Sendkeys "devcon enable usb\vid_0CD5*0003~"
WScript.Sleep 1000
oShell.Sendkeys "exit~"
Wscript.Quit
My reason for doing it this way is that my USB device didn't respond to any of my calls from Labview. Enable/Disable solved the issue...
The thing I particularly hate about above VBS-script is that I need to send the Admin password in plain text...

Can I use the Airport Express to connect to a Linksys Wireless Network and then use the Ethernet port on the Airport for a wired connection to a device for internet access? Would I be able to then also use that Ethernet pt to a Ntwk Hub for more wired c

Thanks for the help. Looked but not clear on what I am trying to do as being possible. Can I use an Airport Express to connect wireless to a Linksys Wireless Router, such that I can then use the Ethernet ports on the Airport to either connected to a PC wired, or even use a hub off the Airport Express to allow multiple wired connections to it?
I am not looking to have the Airport Express extend my wireless network, just connect to it and provide me wired connections in a different location from where my Linksys Route is located. Would prefer to replace Linksys with all Apple, but just not possible financially yet. Thanks for the help.

If the AirPort Express Base Station (AX) is an 802.11n model, then yes, you can reconfigure it as a wireless Ethernet bridge. In this configuration, the AX would join the wireless network provided by the Linksys router and its Ethernet port would be enabled for either a single wired device or for an Ethernet hub or switch for multiple devices.

Hey Guys!
I just got my AirPort Extreme Base, but I can't use my HP Deskjet F4580 wireless printer with it.
The printer is not connected to the AirPort Extreme's USB port. It is placed in another room, and I'd like to use it (the printer) wirelessly (not connected to the USB port os the AirPort Extreme), as I used to. There is no place for the printer close the AirPort Extreme. It worked just fine with my previous wireless router (Linksys WRT54G). I'm very disappointed with the AirPort Extreme Base Station because of that!...
Can you help me? Please?!

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.
